Part 16 Media Linking Application Format (MLAF)
Companion screen applications let user enjoying broadcast programmes access related information on other typically internet-connected devices. N15096 Requirements for Media Linking Application Format (MLAF) provide use cases and requirements on standardized technology in this domain. REF _Ref401149193 \h \* MERGEFORMAT Figure 2 shows the connections that a bridget should create from a professional production to social media or other websites. Source media are images, music and video clips. The Bridget will provide a content and destination description.

Compact Descriptors for Video Analysis (CDVA)
The envisioned activity which will go beyond object recognition required for example in broadcast applications. Especially for automotive and security applications, object classification is of much more relevance than object recognition ( REF _Ref377314454 \h \* MERGEFORMAT
Figure 3, REF _Ref401494958 \h Figure 4). MPEG foresses IP-cameras with a CDVA encoder which enables search, detection and classification at low transmission rates. Related technology within MPEG can be found in MPEG-7 and video signatures.
Figure SEQ Figure \* ARABIC 3: The upper part of the diagram shows the Analyze-Then-Compress (ATC) paradigm. That is, sets of video features are extracted from raw frames and encoded before transmission resulting in low bandwidth communications. This is opposite to traditional Compress-Then-Analyze (CTA) paradigm, in which video features are extracted close to complex visual analysis.
Figure SEQ Figure \* ARABIC 4 Usage of CDVA for identification of classes and recognition.
It is foreseen that identification of classes is much more challenging than object recognition. This work might start later than the work on detection and recognition. For detection and recognition, challenges include flexible objects and specular surfaces. Furthermore, low latency is required.
In order to prepare for an evaluation, N15089 Call for Proposals for Compact Descriptor for Video Analysis - Search and Retrieval (CDVA) describes the frame work for the evaluation to take place at the 113th meeting. N15087 Data Requirements for Compact Descriptors for Video Analysis in Search and Retrieval Applications describes the goals of the standard. Initial evaluation procedures are shown in N15088 Compact Descriptors for Video Analysis for Search and Retrieval Applications: Draft Evaluation Scenarios. N15042 Compact Descriptor for Video Analysis (CDVA) provides an overview for Search and Retrieval as well as Detection applications. N15320 AHG on Compact Descriptors for Video Analysis continues the work.
Free Viewpoint TV
Free Viewpoint TV was the vision that drove the development of many different 3D video coding extensions. It is now time to take back a step and see where the future of 3D will go. Super-multiview displays and holographic displays are currently under development. They will provide horizontal as well as vertical parallax. Hence, we need further extensions of current multiview technology, which assumes a linear camera arrangement, in order to accommodate for more general camera arrangements for future displays. For interaction and navigation purposes, modern human computer interfaces need to be developed. The purpose of the exploration was previously described in N14546 Purpose of FTV Exploration.
N15048 Experimental Framework for FTV shows the further work of the FTV group. It was agreed to use high-resolution 10s FTV video without depth data as test material. The dismissal of depth data might create an FTV encoder/decoder solution that can work with arbitrary video input. For navigation applications, five arbitrary views will be used as test data. Evaluation will be done on stereo displays and displays with more views if they are available. As anchors, MV-HEVC and 3D_HEVC are used. N15095 Draft Call for Evidence on FTV provides details of the test conditions.
The adhoc group N15319 AHG on FTV (Free-viewpoint Television) will continue to work on this long-term exploration.
Future Video Coding
One of the very important users of MPEG-technology is the mobile industry. It is expected that the 5G-Network will be ready between 2020 and 2023. Therefore, it might make sense for MPEG to have a new generation of standards ready by 2020. This might require a new CfE on video coding technology in late 2015 or early 2016.
In N15090 Requirements for a Future Video Coding Standard (Draft), MPEG points towards the goal of a future video coding standard. The N15279 AHG on Future Video Coding Standardization Challenges will refine the document.
Genome Compression
Today, DNA sequencing creates a lot of data. One data set is easily about 800 Mbyte. Typically, several data sets are made for one person. Given that today machines are optimized for speed and not for accuracy, an interesting opportunity for compression technology might exist. TC276 Biotechnology is currently not considering compression. N15098 Tutorial on Genome Compression gives an introduction to the field.
N15093 Requirements on genome compression and Storage (Draft) lists initial requirements that need to be sanctioned by industry and users. N15092 Database for Evaluation of Genome Compression and Storage provides genome data that can be used for compression experiments. The adhoc group N15322 AHG on Requirements on Genome Compression and Storage will continue this exploration.
High dynamic range and wide colour gamut content distribution
Several film studios currently master movies for digital cinema and DVD separately since the colour space of the cinema is much larger than the colour space of a regular TV set. The industry would like to master just one version of the content using the xyz colour space as one example of a Wide Color Gamut (WCG) colour space. Furthermore, future TV will use High Dynamic Range (HDR) displays. In order to adapt to the different displays and projectors, transformation hints are desirable which instruct the terminal how to scale the colours of the content to the capabilities of the display. Furthermore, the signal needs to be deployed with an amplitude resolution accommodating HDR. Deploying video in such a way would also allow consumers to actually benefit from a WCG and HDR of a new TV screen.
At this point, tools for supporting bit depth scalability as well as WCG scalability are available. An appropriate profile definition is on its way.
For B2B application like contribution, a bitrate of 25 Mbit/s is sufficient coding HDR WCG content using HEVC. For B2C applications like Blu-ray or broadcast, there might be a need for further improvements in coding efficiency. As anchors for evaluations, HEVC main at 10 bit or 12 bit might be used.
The group plans to create interchangeable test material. There might be a chance to issue a Call for Evidence at the 111th meeting. However, at this point only limited improvements at 10 Mbit/s were demonstrated.
N1502 Draft Requirements and Explorations for HDR and WCG Content Distribution summarizes the requirements and use cases for HDR and WCG applications.
Based on N15028 Draft Call for Evidence (CfE) for HDR and WCG Video Coding, MPEG developed N15083 Call for Evidence (CfE) for HDR and WCG Video Coding with results expected at the 112th meeting. N15084 Requirements and Use Cases for HDR and WCG Content Distribution describes the environment for using HDR and WCG. Depending on the results of the CfE and external requirements, a time line for further standardization work will be defined. It might happen that a CfP will be issued in parallel to ongoing standardization work.
MPEG also requests further test material as described in N15099 Call for 1000 and 4000 nits Peak Brightness test material for HDR and WCG Video Coding.
Liaison letters N15097, N15280, N15281, N15282, 15283 and N15284 were sent to numerous organizations.
The adhoc group N15318 AHG on Support of HDR XYZ Color Space and HDR will finalize test conditions and conduct a subjective test of the submissions to the Call for Evidence.
Media Orchestration
For applications like augmented broadcast, concert recording or class room recording with several cameras as described in N15091 Context and Objectives for Media Orchestration, play back requires spatial and temporal synchronization of the different displays. N15323 AHG on Media Orchestration will work on this topic.
Media Wearables
N15200 Exploration on Wearable MPEG describes a potentially new item for integration of MPEG-technology into clothes and other wearables.
Screen Content Sharing Application Format
N15086 Draft Requirements for MPEG Adaptive Screen Content Sharing Application Format combines technologies for transport, coding and composition in order to enable the description of contents of computer screens based on components like background, window, video etc. Screen content coding, digital item identifier, MMT and MPEG Composition Information are relevant technologies. The Adhoc group N15321 AHG on Screen Content Sharing Application Format continues to refine the requirements and specification. A timeline needs to be specified.
Media-centric Internet of Things
The Requirements subgroup recognizes that MPEG-V provides technology that is applicable in the area of Internet of Things. N15085 Exploration on Media-centric Internet of Things (draft) provides definitions, use cases and requirements. The Requirements subgroup would like to ask MPEG members to encourage relevant external organizations to share their views on this subject as it relates to digital media. Work continues in N15324 AHG on Media-centric Internet of Things (MIoT).

MPEG-2 Systems (13818-1)
Topics
ISO/IEC 13818-1:201x AMD 2 Carriage of layered HEVC
This amendment will specify layered coding techniques, namely multiview and scalable HEVC coding. Layered media streams need to be supported by the transport formats in a way that different layers can be encapsulated and transported individually.
ISO/IEC 13818-1:201x AMD 3 Carriage of Green Metadata
This amendment specifies a format for carriage of green metadata that enables display power reduction in MPEG-2 TS. The metadata consists of frame statistics and quality indicators. This metadata allows the client to attain a specified quality level by scaling frame-buffer pixels and to reduce power correspondingly by decreasing the display backlight or OLED voltage.
ISO/IEC 13818-1:201x AMD 4 Carriage of additional MPEG-4 audio profile & level
This amendment extends Table 2-71 with more MPEG-4_audio_profile_and_level assignment values.
ISO/IEC 13818-1:201x AMD 5 Carriage of 3D Audio
This amendment defines stream type, descriptors and buffer model to carry MPEG-H 3D audio bitstream in MPEG-2 TS. Two stream types will be assigned to distinguish main stream from auxiliary stream. Descriptors will provide information on user selectable and/or modifiable audio objects and information on which object contains either supplementary or main audio. T-STD extension will allow
splitting an encoded audio scene into several elementary streams. One single audio decoder decodes all elementary streams to one audio presentation. Each of those elementary streams carries one or more encoded channel signals.

Suggested an issue with Operation Point Descriptor being mandated in standard and not mandated in Annex U.
Agreed to remove inconsistency between mandated operation descriptor and the implied example in Annex U.
M 35924 Qualcomm
Highlighted some issues with Operation point descriptor and proposed changes.
Agreed to add auxiliary and auxiliary enhancement to tables 2-50 and 2-103.
Agreed to changes to the Operation point descriptor syntax and semantics. There is dependency of some elements in this program level descriptor with other elementary level descriptors.
M 35944 Fraunhofer HHI
Suggested changes to text for clarification of hierarchy descriptor use and mandate.
Agreed to include in study text.
m35626, m35869, m35872
DIN comments included review of contribution m 35869 which suggested new descriptors and contribution m 35872 which proposed updates to study text of PDAM 5.
NB comments from ANSI and DIN were accepted including changes proposed in m 35872 as this aligned the transport with that in audio. M 35869 was postponed to next ballot cycle so that other NB experts can review this.
We approved DoC ISO/IEC 13818-1:2014 / PDAM 6 and text of ISO/IEC 13818-1:2014 / DAM 5. (Mar 6, 2015). Contribution M 35869 will be an output document for review by national body experts.
M 36109
suggested a possible error in PES header of ISO/IEC 13818-1:2014.
The group agreed that this was an error that seems to have been introduced during the amendment for carriage of SVC and agreed to produce an errata document listing this issue. Based on feedback from national body experts to the next meeting, we will produce a corrigendum to ISO/IEC 13818-1:2014.
M 35963
suggests using MPEG section method for carriage of quality access units instead of PES carriage to harmonize with DAM 3 (carriage of Green metadata). In addition, it also uses a similar buffer model as Green metadata system.

The SAP type field goes to 4 bits.
we add
"For the purposes of these definitions, the SAP is the access unit which is described by Annex I as located at Isau and/or Isap.
Note The distinction between Isau and Isap is only needed to distinguish between referring directly to the access unit, and referring to its containing structure."
m35958 Clarifications on Channel Layout Box in the ISO/IEC 14496-12 ISOBMFF study DAM4
m35484 DRAP sample group in the ISOMBFF
Thank you. We agree this belongs in a future version of part 12, but wed like to look at the DASH implications before we go ahead. Perhaps calling these DRAPs a SAP (type 7?) would help with the labeling. We need to look at how the layer above (e.g. DASH) can find both the IRAP (sync sample in our terms) and the DRAP. We should look also at how this relates to temporal scalability and subsequences.
We put this for now in our defect report though its not a defect, as such.
m35922 On the concept of random access point in 14496-12 and 14496-15
Yes, time to clean up. Into the defect reports for parts 12 and 15.
m35777 Correction to the user-data box in movie fragments
We should think about the replacement rule for user-data; we insert a section in the defect report to think about it.
We agree to (a) move the text to the movie fragment section and (b) reference it from meta-data and user-data, and of course fix the user-data box header. Into the new integrated edition (as a part of the COR/amd4 handling).
m35831 Provision for verification of data integrity of ISOBMFF structures
We have questions about how often it is the case that the transport layer (disk, network, whatever) delivers us files but with errors that it did not detect. E.g. in HTTP or FLUTE, you know which byte ranges of the file you received and which are missing. However, maybe there are use cases. We can see this getting used as the basis for a signing mechanism, which some might like. We should probably start a TuC for this whole area (partial files, errors, and so on).
m35905 Signaling of Partial/Corrupted ISOBMFF
Thank you for this input; we will form a document that carries all the emerging ideas in partial file storage. Having looked at this and other contributions, it is becoming clearer that we might usefully work out what exact scenarios error cases we are trying to handle. Experts are encouraged to contribute to the ongoing document.

See the comments above on m35905.
m35921 On sample grouping type in 14496-12 and 14996-15
Agreed at least to clarify according to option 3 for the general grouping type parameter. Into the defect report. We note however, that the sample group description index can be in multiple sample to group boxes that have different grouping type parameter values.
We keep the layering etc. in the grouping type parameter (this is amendment 4 material). We suggest that we go to 4 bits for the SAP type, for safety; maybe more will come along (like DRAP).
m35950 Comments on Edit List Box in the ISO/IEC 14496-12 ISOBMFF Defect Report
Since edit lists cannot occur in movie fragments. We also need a note explaining the difference between an empty edit and a zero-duration media edit. Into the defect report, thank you.
m36113 Inputs to the defect report for ISO/IEC 14496-12
Taken as the basis for the defect report, but note all the additions from other contributions.
m35485 USNB Technical comments (RE: WG 11 via SC 29)
We will need to do an update at some point, documenting the new conformance files, and well insert a paragraph pointing at this open source, as suggested.
m35984 Progressing Unidirectional Delivery of File Format
Integrated into the exploration document.
m35776 File format reference software and conformance update (2)
Thank you. We note updates will be needed to track the FDIS.
m35982 ISO BMFF conformance software: gathering comments
The feedback from plenary is that the conformance document will reference but not contain the indicated software.
m35879 Carriage of spatial relationship for dynamic ROI in video panorama in ISOBMFF
This is interesting and has multiple use cases. We note that sample groups already exist and are suitable for few alternatives use case. Adding to the sample table doesnt seem right. In the track case we could support non-rectangular ROIs, which is nice; we could also have multiple tracks, and not all the ROIs need to have a pre-computed video track. The track format could be textual or XML, of course, and we have meta-data XML tracks already.
We would like to see a design that documents ROIs, links to pre-computed tracks, handles resolution scaling (e.g. for DASH), and so on.
We are not sure where such a design would land in terms of specification. This is logically a media format (like metrics).
We make a WD at this meeting; we need to decide where it will be, before we request a sub-division. Perhaps under metrics, 23001-10?

ISO/IEC 14496-15:2013 AMD 1 Carriage of Layered HEVC
This amendment specifies the storage of video bitstreams consisting of multiple views and the associated depth, encoded based on Annex I of ISO/IEC 14496-10. The design is based on the MVC file format, which is specified in Clause 7 of ISO/IEC 14496-15, in a backwards-compatible manner. In the design, storage of the texture and depth of a particular view in either separate tracks or the same track is supported. The design also includes the signalling of various indications, such as the presence of texture and/or depth for each view, as well as whether the texture or depth component or both of a view is required for the presentation of another view. The amendment also adds the signaling (using HEVC video descriptor) to indicate use of HEVC low-delay coding mode in each access unit where the STD buffer management is performed using the HEVC HRD parameters

m35833 Optional MIME parameters for L-HEVC in ISO/IEC 14496-15
We note that the whole question of whether there are multiple bitstreams and their relationship etc. is already an issue for the codecs parameter. We note that the OlsIdx is also only useful if somehow it is conveyed between the can you play this decision and the supply of the actual media.
m35834 Indication of output layer set for L-HEVC in ISO/IEC 14496-15
We need to say its the index in the VPS, and also say that there is a restriction there be only one VPS in the track (and hence only one sample entry as well). We need an open question of what to do with a bitstream that doesnt obey this restriction, also.
m35848 Clarification on Layered HEVC storage in ISOBMFF
We agree that wed like to mark operating points in a track saying if you process this track and resolve extractors, the result is a bitstream that is HEVC conformant corresponding to a given operating point; neither subsetting of the NAL units, nor implicit fetching and re-ordering from other tracks, is needed. We agree the one-layer per-track is much simpler, and we remove profile-tier-level from the LHEVC config record and make that reserved space (so that the layout stays the same). We study this for a meeting period.
m35918 Indication of hybrid codec scalability for L-HEVC in ISO/IEC 14496-15
We note that the limited number of possibilities really suggests a sample group, and ideally its on the base layer as it documents that layer (and also how it is used, alas). Sample group on the base layer and the flag says not surely not used by any enhancement layer.
m35923 On HEVC and L-HEVC file formats
For problem 2, option 1 is preferred; the sample groups help with the layers. Otherwise accepted.
m35946 ObjectTypeIndication code point for HEVC
The RA to assign the next code after AVC, for HEVC, and to insert the HEVC codec types in the codecs table, with the objecttypeindication shown.

m35849 Storage of WebVTT Thumbnail tracks in ISOBMFF
We think that the meta handler should be used, with an appropriate role user-data item, and indeed a thmb track reference.
We should propose an amendment to part 30, and make sure that the thmb track reference is in the part of the image file format to be moved to part 12.
Yes, the shadowing is a nice technique as simple relative URLs are supposed to work.
We should consider this for an amendment of part 30, documenting how VTT non-caption tracks can be used.

This amendment extends text and classification descriptors for descriptive metadata for audiovisual content. These extensions address existing data types and add some elements and attributes. The first one improve internationalisation for text-based metadata by identifying the script(s) used and enables carrying strings represented in multiple character sets in the same XML document, using encoding. The other extends classification metadata in order to: (a) improve interoperability with existing metadata formats used in professional media production, (b) increase cardinality of some elements and (c) add attributes and a version element.

This format defines a way to encrypt media (audio, video, etc.) in files of the ISO base media file format family. By using a common encryption format, a single media asset can be used by several services and devices using different digital rights management systems, and the implementation complexity that would be consequent on having duplicate files and formats for the same content can be reduced or eliminated.

This adds support for a general framework for sample variants in the ISOBMFF. This would be used by a forensic watermarking system to modify the base sample, but is independent of the watermarking algorithm. Variants are sample data that may be used by a decoder and DRM system to ultimately output video or audio that is marked in a way that can be unique to individual decoders or decoder product models. The application of the variants during the decode process is under control of the DRM system (and ultimately the content provider).

Summary of discussions
m35711 An editorial update of the Image File Format specification (ISO/IEC 23008-12)
Definitions need to be ISO style; no article and no period.
Hm, primary image is confusing wrt primary item; new word?
We need Prof. Timmerer to look at the URN.
7.2.2 needs a rename, its not the right title.
We go with ISOBMFF and lower_with_underscores.
Thank you.
m35778 Suggested updates to the HEVC Image File Format
yes, we change simr to cdsc. The change to allow simr in the init means the existing cdsc direction is acceptable. We dont accept the thumbnail direction change.
We adopt a grid item that does constrained grid layup; the tiles must be all sized width/rows by height/columns.
aligned(8) class ImageGrid { unsigned int(8) version = 0; unsigned int(8) flags; FieldLength = ((flags & 1) + 1) * 16; unsigned int(8) rows; unsigned int(8) columns; unsigned int(FieldLength) output_width; unsigned int(FieldLength) output_height;}
Yes, the fill is a color in RGB in sRGB space. We discussed whether we would like an alpha here to allow transparent background fills. We need to clarify what the auxl alpha means when the base image also has an alpha plane. It overrides? Composites? We agree to make this RGBA (need to find a suitable definition).
Author to draft the text for a loop box at the movie level.
We will study the general question of box directories, but not specifically for this format.
m35825 A grouping mechanism for the Image File Format (ISO/IEC 23008-12)
Yes, we adopt v2, with item_IDs and track_IDs. Yes, if track_IDs are used then this box must be at file level no item have the same ID as a track. The structure goes into the section to go to part12. The group types may be image file format specific, of course. We adopt this with the alternative reference for now. We are slightly concerned that base references appear to imply an operational dependency, whereas it is a semantic dependency only,
m35826 Miscellaneous cleanups for ISO/IEC 23008-12
We agree the new handling of aux items and tracks and note we should use the hidden flag to match the track (not) in movie flag.
We make the refs sample group a should as there are cases (IPIPIP, DRAP) where one would not need it.
Yes, we clarify the requirements for pict tracks but make the general statement first.
m35828 Multiple-of-90-degree rotations for image sequence tracks in ISO/IEC 23008-12
But clap and other sample entry processing happen before the matrix.
m35829 On brand specifications for the Image File Format (ISO/IEC 23008-12)
Thank you. We agree that file: URLs are dangerous, fragile, sometimes ambiguous and poorly supported.
m35830 Optional MIME parameters for ISO/IEC 23008-12
We agree that
comma-separated list of at least the primary item and other non-hidden items should be possible
its important to know the base image types of a derivation, probably more important than the chain
we can rely on profiles to some extent to know what operations must be supported
some composition operations (grid, overlay) require a sub-parameter (number of inputs, pixel count)
wed like to use the derivation 4CCs if possible and not have to invent URLs (yet)
codecs and profiles parameters are ideally as short as possible
How is it if we say that (a) at least the primary item must be documented (b) for a derivation chain, the base image item(s) must be documented (even if hidden) and in general (c) hidden items should not be included.
We will need to document the derivation chain and sub-parameters for derivation operations, as this contribution says (e.g. the pixel count). How?
Choices:
put only the base image type in; snag: for some derivation operations (notably overlay) this is an unlimited exposure;
document the items in a derivation tree using + and document that the sub-parameters of a derivation operation are the image count and pixel count, as suggested;
item.grid.2995200+hvc1.A1.80.L93.B0+clap+jpeg
item.clap+jpeg
The pixel count is mandatory if an operation required buffer image storage greater than twice the largest coded image in the parameter. (The pixel count sums the input and output images). The derivation operations are mandatory if either (a) they are not required by all profiles or (b) they are required to have the pixel count parameter.
We got with (h), a minor mod of the proposal, where instead of URLs and indexes, we use the 4CC instead
m35840 Comparison of BPG and MPEG Image File Format
We could usefully note the ability to interleave item extents (e.g. alpha and image) to allow progressive display. Do we need to point out to the video team that YCgCo may be interesting? Has HEVC ever been tested on CMYK? It might help to make our WD of FDIS public.
m35844 Review of use cases on the Image File Format
We accept to have an hvt1 item have an init reference to an hvtC item, which is a full hvcC config plus a mandatory tile location.
Overall summary
In reviewing several of these we think that architecturally:
we need to be able to group transformations into a single item
we should box the init material and allow a restricted set of basic declarative data in the init record (width+height, pasp, etc.)
we might usefully bundle meta-data as well, but this is not urgent
flag on the item info entry for hidden seems fine
we take the item groups in, but make the contents be item/track IDs, and maybe only the altr group type for now?

Summary of discussions
m35927
Summary: supported USNB in pointing out problems with flexible parameter insertion. It suggest to signal the specific scheme(s) client needs for URL parameter insertion.
Disposition: Partially accepted the problems. We will address the solution with separate descriptors and revise the UrlQueryInfo to tie to those descriptors.
m36073 Liaison Statement from 3GPP on MPEG-DASH
Summary: It provides the use-case in which a mosaic of various video channels are encoded together and provides to the DASH client using a MPD. While streaming and playing this mosaic as one single stream and decoding by one decoder, the user can click on o channel area in mosaic and the DASH client gets the external MPD for that channel, does a soft transition and start playing back the corresponding audio and video stream. 3GPP asks whether this use-case can be addressed by SRD and current MPEG spec.
m35954 Mosaic service based on SRD
Summary: provides a solution for 3GPP use case by having a new value for role as multiple, and using descriptors for linking the independent MPD URLs.
m35978 DASH: On Amendment 2 (SRD and Authentication)
Summary: lists the use-cases of authentications and their requirement, various methods of token exchange and suggests that the authentication/authorization annex of DAM2 is not adequate for building interoperable services.
m35877 A WebSocket-based Transport Protocol to Carry SAND messages

Disposition: Accepted with revision: Change it to essential descriptor and add it as an example in informative part of WD. Also add the SAND diagrams to DASH client in WD.
m35976 Addressing 3GPP Use Case
Summary: propose to use XML for message formats. Use 1) a header extension in HTTP response. 2) 300 response including a sand header. 3) 400 message and include a sand message.
Discussion:Do we need delivery method more frequent than a segment request? M35976 can send messages as fast as the segment request.
Disposition: Accepted assistance, enforcement and error case for signaling the sand message method in the WD. We will change the names. Also add a note in WD that common parameters for messages are needed such as publish time and validity duration.
M35965 On SAND Metrics Reporting
Summary: to suggest use the XML format for metrics
Disposition: We add a note in WD: we are considering XML format for metrics. We welcome experts to bring alternative format proposals and benefits.
m35843 DASH SubAssetIdentifiers and Sub-Representations

Participants: Interdigital, TNO, CableLabs, Qualcomm, bitmovin, orange, Microsoft.
Send this CEs use-cases to other orgs and asks their inputs.
Revisit the TuC Playback control after this CE.
m35938 Ad content signaling in MPEG-DASH
Summary: suggest an attribute for skipping/not-skipping
m35935 Live edge hinting for MPEG-DASH
Summary: proposing an attribute to MPD to indicate the latest available segment in live server.
Disposition: Noted. The r count in SegmentTimeline provides the latest available segment. The contributor to review segment timeline and see if it can address the use-case.
m35937 Descriptive information for adaptation set and representation
Summary: proposes new attribute @name at period, adaptation set, or representation, to provide descriptive information (pure text with no semantical meaning) to be used by application, to show it to user/ to display.
Disposition: Include this in TuC, with changing name to label.
m35971 Playback Enforcement in DASH
Summary: proposes the signaling rule in MPD: content range and operations.
Disposition: Subject of CAPCO CE. Joins the CE.
m35979 Simplified On-Demand Multi-Period Content
Summary: proposes a new attribute and some extension to allow breaking an on-demand period into two virtual periods
Disposition: Accepted in TuC. Note: the backward compatibility should be investigated.
m36034 DASH: Temporal QoE Signalling in MPD for DASH Subrepresentation
Summary: proposes to include a distortion attribute for subrepresentation in MPD.

Disposition: Accepted to be included in TuC.
m36066 On HTTP caches, CDN and media origin - informative
Summary: describes how origin servers and CDN interact.
Disposition: Include in TuC with the note that this section is a candidate for Part 3.
m35839 Supplemental property descriptor for fast start-up representations
Summary: Using SHEVC to create segments that are low resolution at the beginning and increase resolution as segment progresses. Define one representation in the adaptation that have these segments. Use the supplemental descriptor to signal this Representation
Disposition: Accepted with revision in TuC. For any codec, SHEVC is a specific case.
m35885 Multi-Stream Streaming in DASH (Multi-Stream DASH)
Summary: multiple streams at same time. Streams could have relationships.
Disposition: Noted. Use-cases are either already addressed by SRD, labels, and current DASH features or fall in the application layer.
Recommendation on DAM2 Role extension
Summary: We believe
1) Roles values are characteristics of the content. However the meaning of each value may imply the ways they can be used by client.
2) Reviewing the received liaison response, there is no universal Roles table or equivalent defined anywhere. W3Cs Kind defines some of the values, but additional values are defined by SCTE and ATSC and DVB. But DVBs signaling differs from ATSC and SCTE.
3) There is a benefit of a universal table. The benefit is achieved if and when the deployments use the same common scheme. We prefer to reference an external standard or CICP spec for it. However, since there is no specification available that are acceptable to all organization and since the Role may be used by stand-alone DASH client (so called Type 1, which basically plays back the received MPD), we recommend to extend the table that can address common important applications and also is aligned as most as possible with various specification. We understand we cannot achieve full alignment with already defined signaling by some consortia. But by extending the role value we avoid further fragmentation.
Recommendations:
Revise the DAM2 Role value extension table with the following:
DescriptionsTextual or audio media component containing a textual description (intended for audio synthesis) or an audio description describing a visual componentSignVisual media component representing a sign-language interpretation of an audio component.MetadataMedia component containing information intended to be processed by application specific elements.hearing-impairedAudio component with improved intelligibility for hearing impaired listeners. Note 4: Role descriptors with values such as main, alternate (as alternative) , dub (as translation), "subtitle", "caption", "descriptions", "sign" or "metadata" may be used to enable assignment of a "kind" value in HTML 5 applications for tracks exposed from a DASH MPD.
Note 5: The descriptions may be interpreted as service for visually impaired if @contentType is audio.
The values related to audio to be shared with audio subgroup and get its input.
Include a descriptor scheme by which an adaptation set can point to another adaptation set, using destination adaptation set id. This scheme can be used with Essential/Supplemental Descriptor only at adaptation set level.

m35657 LiaisonAMD2 Statement from CableLabs
Summary: Replied on Role value extension included in DAM2 in details. Found some values useful, some redundant, and in some cases asks for clarification or removing/adding the constraints. For instance:
The submitted values description, sign and metadata from Table 2 in the Liaison Statement are important to include as they provide a direct mapping to the same HTML track kind attribute values defined by HTML5 [1] and HTML [2].
The submitted value description, which is defined in HTML, should be used and the submitted Role value visually-impaired should be dropped since it is redundant with description.
The submitted value description should to be changed to descriptions to match the usage in HTML.
The submitted value hearing-impaired should be useable in the Role descriptor. Remove the last sentence in semantic.
Modify the added Note to Role table as the following:
Note 4: Role descriptors with values such as main, alternate (as alternative) , dub (as translation), "subtitle", "caption", "description", "sign" or "metadata" may be used to enable assignment of a "kind" value in HTML 5 applications for tracks exposed from a DASH MPD.
Disposition: Noted. Since we received liaisons from DVB, ATSC, 3GPP and CableLabs, we recommend to revise the DAM2 such that it accommodates the most requested values as indicated below.
m35798 Liaison from DECE
Summary: Points out the related MovieLabs specs similar to the Role Descriptor. Some of values listed in this liaison are signaled differently in DASH, using different descriptors or attributes, and there are not the subject of Role. Therefore, we dont think there is a meaningful mapping between Movielabs mentioned specs and Role in DASH.
Disposition: Noted.
m35912 SCTE DVS Liaison on DASH
Summary: Similar to m35657, outlines some requested revisions for some of the values, ask to eliminate one and also proposes a replacement table for Roles additional values, improving the semantics. Also it request to have a signaling mechanism for receiver-side mix.
Disposition: Noted.
Recommend the followings:
Add the following as a note at the end of Role values table:
Note: The descriptions may be interpreted as service for visually impaired if @contentType is audio.
Add a descriptor scheme into FDAM 2 that enables the link from one adaptations sets to another by using id in value.
Since we received liaisons from DVB, ATSC, 3GPP and CableLabs, we recommend to revise the DAM2 such that it accommodates the most requested values as indicated below.
m36018 ATSC Liaison on DASH
Summary: proposes the replacement table for Roles additional value table in DAM2, with the intension of improving the semantics. This table is referenced in few ATSC specs.
Disposition: Since we received liaisons from DVB, ATSC, 3GPP and CableLabs, we recommend to revise the DAM2 such that it accommodates the most requested values as indicated below.
m36073 Liaison Statement from 3GPP on MPEG-DASH
Summary: 3GPP does not maintain any such metadata and are not planning to do so in any near future. It would support a central repository for such metadata and may consider referring to this if considered appropriate.
Disposition: Noted. The liaison support doing this if it is designed as a central place.
m36079 Liaison Statement from DVB
Summary on Role: The usage of Role is defined in 6.1.2 and 7.1.2 of the DVB Bluebook A168 (soon to be ETSI TS 103 285), from which an example audio table is copied, can be found at:
HYPERLINK "https://www.dvb.org/resources/public/standards/a168_dvb_mpeg_dash.zip" https://www.dvb.org/resources/public/standards/a168_dvb_mpeg_dash.zip. DVB defines its own accessibility scheme and uses the combination of Role and accessibility descriptor to signal some of the audio representation characteristics.
Disposition: Since we received liaisons from DVB, ATSC, 3GPP and CableLabs, we recommend to revise the DAM2 such that it accommodates the most requested values as indicated below.
m35929 DASH-IF Liaison on Recent Activities
Summary: Auth/Access Authorization section of DAM is not ready for publication due to various use-cases that needed to be addressed. One or multiple token exchange schemes are needed to be defined with DAM2.
m35929 DASH-IF Liaison on Recent Activities
Summary: provides test vectors with and without MPD updates, being hosted by DASH-IF.
Disposition: to include the links to those pages in WD. Provide a list of test vector classes.

MPEG-7 Visual XM software part 6
After the previous meeting, the possibility of needing to put the second edition FDIS on hold was considered. As no technical record of the given changes existed before, and a possible corrigendum action would span the base text and several amendments, it was decided that a better approach would be issuing the new edition as CD with a clen ballot process. This CD (N15127) was also made available as a public document, which had not been possible with the previous FDIS.
A white paper on the sofware update is targeted for the next meeting.
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51855&id_meeting=163" m36105 Conformance Testing Report for ISO/IEC 15938-3:2002/Amd 3:2009: Image signature tools [Karol Wnukowicz, Stavros Paschalakis, Miroslaw Bober]
The report shows that conformance testing for the Image Signature Tools fails with respect to the descriptor content when different version of external libraries are used, namely ImageMagick (image IO and decoding) and OpenCV (mathematical and matrix operations, filtering, etc.). Effect of OpenCV is much greater than ImageMagick. The conformance failure is primarily with respect to the local signatures; almost all global signatures pass conformance testing. The report also indicates that the conformance conditions are too strict, especially for the local signatures.
Further investigation of the results is needed to decide how to relax the conformance conditions, and how that would affect the precision of matching.
This will likely result in a corrigendum of the conformance testing part, and new reference descriptors.
CDVS
The BoG on CDVS was chaired by Stavros Paschalakis. The notes in this section were primarily recordings from the BoG, which met Monday-Thursday during announced times.
Not yet in position of issuing CD on part 14.
The following output documents were generated:
WD3 on part 14 combining both SW and conformance (N15128).
TM13 document (N15129, this will later be merged into part 14 CD in the future, as "usage guidelines").
Announcement of the awareness event (N15132).
The CD for part 14 is planned to be issued by the next meeting.
Conformance testing and reference software
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51574&id_meeting=163" m35824 CDVS Test Model code optimizations and enhancements [Massimo Balestri (Telecom Italia), Gianluca Francini (Telecom Italia), Skjalg Lepsoy (Telecom Italia), Alessandro Bay (Politecnico di Torino), Attilio Fiandrotti (Sisvel Technology), Massimo Mattelliano (Sisvel Technology)]
Proposes a wide range of changes to the CDVS TM.
Code structure
Split example applications from the TM.
Provide various examples of usage of the CDVS library.
Code optimisation
Switching off the building and use of global descriptor retrieval weight table, which takes up 512 MB in the CDVS library. Minimal effect on retrieval performance.
Computing orientation after feature selection.
Coordinate encoding using integral image.
Matching and retrieval using popcnt instead of look-up tables.
Other
Functionality to perform localisation on retrieval results (currently only pairwise matching).
Change of arithmetic coding software library.
New options and implementation for server-side descriptors (currently fixed descriptor length; now allows all CDVS lengths).
Fixed a syntax error to align with CDVS specification.
The only change in performance is in retrieval, due to the switching off of the weight table, but the difference is minimal. The only change in the descriptors is due to fixing a syntax error to align with the CDVS specification. None of the proposed changes have any effect on the CDVS specification under ballot. It was agreed that the proposed modifications will be accepted and implemented in the TM13.

Crosscheck OK.
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51658&id_meeting=163" m35908 A proposal of conformance test for CDVS [Nicola Adami, Mirko Gagni, Claudia Gargiulo, Stefano Maccarana, Federico Polini, Muhammad Umar Riaz, Riccardo Leonardi]
The proponents had two aims: (1) implement a CDVS encoder from the specification text (FDIS) only, using non-expert developers, (2) investigate conformance testing points and limits within the encoder pipeline. The proposal only focuses on the encoder, checking the FDIS text for clarity and correctness, and determining parts in the implementation that affect conformance. OpenCV is used in the implementation.
Work has progressed to checking global descriptors and keypoints. Global descriptor: Calculate descriptor differences. Keypoints: First attempt to establish keypoint correspondence to +/-1.5 pixels (HM bin size). If this doesn't work attempt to establish keypoint correspondence at greater spatial distances. At +/-15 pixels, 50% keypoint correspondence achived on small set (2-3 images). Possible reasons: incorrect encoder implementation, specification text ambiguity, or high sensitivity in numerical computations?
Proposal discusses a number of stages in keypoint detection were checks can be made.
A few issues with the text of the standard (typographical and editorial mistakes and some ambiguities) are also identified, along with some suggestions to improve clarity.
The group found this contribution very valuable, both in checking the specification text and in providing a platform for development of conformance testing conditions and limits. Proponents encouraged to continue this line of work and report at the next meeting.
BOG Discussions and Progress on Conformance testing and reference software
Regarding the Reference Software, the group discussed a number of changes and additions that are required before issuing a CD, including
A "how to build and run" document for new users of the software
Creating CDVS applications with simple and well-defined IO and command line arguments to descriptor extraction, matching and retrieval.
Creating a "test-bed" environment for one of the public domain databases that were used in the CDVS evaluation so that users can generate results (the database will not be part of the software)
Regarding the Conformance Testing, especially regarding local descriptors, we discussed the various options and concluded that, given the CDVS encoder keypoint coordinate binning and keypoint parameters which are not in the bitstream (scale, orientation), it will be very difficult to establish keypoint corresponces based on location for further verification. Therefore, an alternative approach was adopted, whereby a simple local descriptor matching is used to establish keypoint correspondences, and then it is checked whether the identified pairs have similar locations and descriptor values. A conformance checker "software tool" has already been built and tested during the meeting, more work will be carried out in the AHG.
It had been initially discussed whether it would be beneficial to issue a document reflecting the planned testing of conformance (similar to CE). Later, it was concluded that no conformance testing output CE document is needed, the work will be conducted by the AHG.

Video Coding for Browsers
During the Monday plenary, the BoG led by Mohammed Raad was given the following tasks:
Analysis of claimed type-3 situation: Set up a list of claims from the patents under question (see m35857), identify those that are surely not applying and those that may be disputable (it was later comfirmed that an ISO official gave advice about the appropriateness of performing such an analysis).
Preparation of Preliminary DIS & Draft DoC
The following two documents had already been presented in the AHG on Sunday, and were later reviewed again in the BoG and approved in the Video plenary:
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51243&id_meeting=163" m35493 Proposed DoC of the USNB comments on 14496-31 DIS [Mohamad Raad, Harald Alvestrand]
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51244&id_meeting=163" m35494 Proposed 14496-31 DIS text [Mohamad Raad, Harald Alvestrand]
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51552&id_meeting=163" m35802 Editor's comment on the results of the 14496-31 DIS ballot [Mohamad Raad, Harald Alvestrand]
The document makes recommendations about a possible progress after the DIS ballot. During the MPEG opening plenary, it was clarified that for a reasonable progress the most important aspect would be a better understanding about how type-3 claims affecting the current draft standard.
It was also mentioned that the document contains some aspects which are going beyond the technical mandates of editing. The document was not presented in Video again.
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51607&id_meeting=163" m35857 Followup to m34971 [J. Ridge]
Presented in Video. In the document, Nokia draws the attention of WG11 to the IPR statement related to RFC 6386 "VP8 Data Format and Decoding Guide" that includes a list of patents that Nokia has identified as potentially relevant to the VP8 version submitted to the IETF, and that Nokia believes are also potentially relevant to the VP8 version (VCB) proposed at MPEG. The list is accessible at HYPERLINK "https://datatracker.ietf.org/ipr/2035/" https://datatracker.ietf.org/ipr/2035/. While Nokia believes that the list is accurate, Nokia reserves all rights to identify additional patents or otherwise modify the list in the future.
One difference between the situation in IETF and MPEG may come due to the fact that 14496-31 only specifies the decoder as normative, whereas VP had been submitted to IETF as complete encoder/decoder package.
An initial plan from the Monday plenary had been to work towards an output document to identify the issues.
It was suggested during the meeting in Video Wed 15-17 that the output document should not be interpreted as our judgement about the validity of the claims in the patents mentioned, the purpose would rather be
collect evidence about how the VCB decoder operates in the stages which could be affected by the claims, such that it is easier for interested experts to make their own judgement
to identify in which parts there could be potential need to change the text in the VCB specification
It was however expressed by other participants that experts in MPEG are not able to judge legally (or some of them cannot participate in matters regarding patent evaluations) whether patents apply or not, such that legal evidence would need to come from outside or within an upcoming ballot.
No consensus was reached that such an output document would be agreed upon. This should not mean stopping the analysis performed in a BoG, which however was only attended by very few experts
Suggested solutions were:
to upload the result of the BoG as an input doc
to formulate a document with further analysis of VCB building blocks without taking explicit reference to patents
to leave the issue open and further discuss in Friday plenary.
During Thursday and Friday, no further analysis was performed in the BoG, and no output doc was produced. A resolution was issued asking Nokia to provide more clarity about their claims, particularly with regard to the fact that 14496-31 only defines the bitstream syntax/semantics and decoder operation, and, as reported by the BoG, a substantial amount of claims in the patents refer to encoding.
The Draft DoC (N15125) and Draft Text in Preparation for 2nd DIS 14496-31 (N15126) were approved as output docs.
Internet Video Coding Exploration
During the Monday plenary of the Video SG, the report about IVC visual quality evaluation (N14989) which had been produced in the interim period was approved no objections were raised. The overall conclusion of this report had been:
In summary, considering all cases together, the tested IVC encoder can be considered to be slightly better than the WVC encoder and equal to the VCB encoder. In terms of the visual comparison, it should be noted that not all the common test conditions test sequences were tested, such that this figure cannot be considered complete. Furthermore, the results (both in terms of average BD bit rate and subjective quality) show clear evidence that ITM 10 has significantly improved compared to the ITM 7 configurations that had been used in N14240. This is, in particular, visible for the LD test cases, where ITM 7 had been consistently worse than the other encoders.
The BoG on IVC was chaired by Ronggang Wang. The first meeting of the BoG was held 2015.2.16. The following issues were identified during the Monday plenary of the Video SG to be resolved during the meeting, and further discussed in subsequent plenaries:
Prepare evidence about progress from ITM7 to ITM11 (and if possible include information what can be expected from new contributions). In particular, it would be interesting to assess how close it is to saturation (in terms of technology that would be appropriate for inclusion, and how close it is to AVC high profile)?
Upon this request, the BoG provided the following viewgraphs:
(1) The progress from ITM7 to ITM11, using ITM7 as the Anchor
(2) The performance comparison of ITM11 with WVC, VCB and AVC HP, using AVC HP as the Anchor
Clarify whether more viewing for assessing the visual quality should be performed at the current or better at the next meeting (in the latter case, using ITM12)? Initially consult with test chair on some examples whether the new results would justify performing another round of expert viewing at the 111th meeting; otherwise, rather plan it for the 112th, anticipating from the new contributions that more improvements could be made.
Upon this request, the BoG reported that the blocking artifacts in the ITM10 were much improved by the new contribution on stronger loop-filtering, such that it is likely better to perform more subjective quality assessment at the 112th meeting.
The breakout group made the following remarks upon the results shown:
IVC has been progressed well meeting by meeting, and now, its performance has been close to the peak(close to AVC HP).
The performance of ITM11 for Random Access cases is much better than both WVC and VCB, and close to AVC HP.
The performance of ITM11 for Low Delay cases is much better than WVC, slightly better than VCB, and close to AVC HP.
Several new contributions will be added upon ITM11 to obtain ITM12 in this meeting, and the ITM12 will be expected to be more superior to WVC and VCB.
We have found clear evidence on the visual quality improvement of ITM10 by the new vertion of ITM. We have done some extensive visual testing sequence by sequence from 9:00 to 18:00 in IVC BoG, on the new version of ITM(ITM11 + new loop filter) against VCB and AVC HP, we observed that:
for Random access cases, IVC is clearly better than VCB on almost all test sequences, and very similar with AVC HP.
for Low delay cases, on the sequences of video conference, which are main scenarios for LD, IVC and AVC HP are better than VCB; while for sequences with high motion, on the low bitrate bitstreams, VCB is better than IVC and AVC HP. Overall, the three codecs are comparable for LD cases.
For technical discussions, the IVC breakout group started their meeting from Monday 16:00, with subsequent meetings on Tuesday, Wednesday and Thursday. All recommendations of the BoG as reported below were later approved for adoptions in ITM and WD in the video plenaries of Wednesday (section REF _Ref412282679 \r \h 12) and Friday (section REF _Ref412282698 \r \h 13).
Technical proposals
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51496&id_meeting=163" m35746 Bug report on ME initialization in internet video coding (IVC) encoder [Seung-ho Lee, Sang-hyo Park, Euee S. Jang]
In CS2 case, the current IVC test model (ITM) encodes I and P frames only, not B frames. However, we found that one parameter related on B frame affects the whole encoding process though B frame was not used at all. In this contribution, a bug that may not be intended on ME initialization process is presented, and a simple way is proposed to fix it.
Recommendation of BoG: adopt it into the next version of ITM encoder software.

HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51497&id_meeting=163" m35747 Enhanced encoding technique on the quantized coefficients of chroma for internet video coding (IVC) [Seung-ho Lee, Sang-hyo Park, Euee S. Jang]
In the current IVC test model (ITM) encoder, the rate-distortion optimized quantization technique is applied to only luma blocks, not chroma blocks, which may results in distortion further on the quantized coefficients chroma block. To increase coding efficiency, a simple encoding technique that tries to optimize the quantization process on chroma block pixels is proposed.
The proposed method shows a 0.8% gain in CS1 and a 1.6% gain in CS2.
Discussion:
Only consider chroma distortion, but dont consider rate cost;
To check if subjective quality will be affected with this method.
Recommendation of BoG: to adopted it as an optional tool in ITM encoder.

HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51498&id_meeting=163" m35748 Improved set of reference frames for internet video coding (IVC) [Seung-ho Lee, Sang-hyo Park, Euee S. Jang]
This contribution presents an improved set of reference frames to increase the coding efficiency of IVC. The use of multiple reference frame (MRF) adopted in ITM 6.0 showed good coding efficiency, referring successive previous frames that could contain more accurate motion information than the very previous frame. To give different chance to encoder, we propose a different set and associated encoding method that enable to refer pixels of frames located on longer distance than the original frames.
The experimental results showed that the proposed method achieved 1.6%, 2.1%, and 2.3% gains in terms of BD-rate on Y, U, and V components respectively in CS2.
Discussion:
To replace the traditional successive multiple reference frames with temporal index of 0, 1, 2, 3 and 4
with temporal index of 0, 1, 3, 7 and 11
If ( reference_frame_index < 2)
new_reference_index = reference_frame_ index;
else
new_reference_index = 4*(reference_frame_ index - 1) - 1;
Remmendation: to adopt it into the next version of IVC WD.

HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51641&id_meeting=163" m35891 Temporal Dependent Rate-Distortion Optimization in Internet Video Coding [Ce Zhu, Yimin Zhou, Yanbo Gao, Shuai Li, Qiang Peng, Lu Yu]
This proposal attempts to apply and customize the temporal-dependent RDO method under Low-Delay configuration for one-pass Internet Video Coding (IVC). Under the Low-Delay configuration, the influence of the current coding unit is predicted from the collocated unit in the previous frame due to the future frames being inaccessible.
Experimental results demonstrate that the temporal-dependent RDO scheme implemented on ITM 11.0 achieves 1.2% bit saving on average for CS2 (Low-Delay) coding structure.
Recommendation of BoG: to adopt it as an optional tool in ITM encoder.

HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51642&id_meeting=163" m35892 Fuzzy Rate Control Scheme for Internet Video Coding [Yimin Zhou, Ce Zhu, Min Zhong, Minke Luo, Lu Yu]
This contribution proposes a frame level rate control scheme for internet video coding (IVC). In view of unpredictability or uncertainty of video content and channel status, a fuzzy controller is introduced to minimize the deviation between the target buffer level and the current buffer fullness. To improve the precision of fuzzy control, an input domain determination method is presented. The proposed rate control scheme is implemented on ITM 11.0. Extensive experiments demonstrate that the proposed rate control scheme maintains an accurate variable bit rate control and steady buffer size during the coding process while achieving coding gains on all-intra (AI), CS1 and CS2 structures separately. This proposal is a revised version of the previous one M34388 REF _Ref409701669 \r \h [1].
Recommendation of BoG: Adopt it in the encoder side.

This contribution proposes to add an enhanced loop filtering tool in the coding loop of Internet Video Coding Test Model. Experimental results show that the proposed scheme can remove the blocking artifacts and improve subjective quality significantly.
Contribution: enhanced loop filtering tool.
Discussion:
Different videos were shown during AHG meeting to compare between the original and the proposed, which were RaceHorses and BQMall. Video and stopped image were evaluated.
- It was observed from the demo videos, blocking artifacts have been greatly reduced.
- One of participant said if we stopped the video then we can find the proposed outperforms, but in video the improvement is not so obvious.
- Still both shows flickering effect in high QP bitstreams.
- Flickering effect should be resolved.
Main changes are: adding stronger filter with additional conditions (called intra block difference), it still can be covered by the claims of the expired de-blocking patent.

This contribution presents ongoing works aiming at developing dataflow architecture for the scalable HEVC decoder within the RVC framework.
Based on the SHM 4, parsing of the VPS extensions is added that contain multi-layer syntax elements necessary for the decoding of the scalable HEVC profile.
First report about scalable main 8 profile
Further update and specification by the next meeting (likely not many more FUs e.g. VPS, inter-layer processing, but synchronization in data between base and enhancemen

To improve the performance of the dataflow HEVC decoder, some optimizations are applied and involve modifications in the architecture.
This document presents a set of optimizations applied on the intra prediction (IntraPred), the inverse integer transform (xIT), the QP generator (QP_gen) and the reconstruction (SelectCU) actors. These optimizations are currently applied on a testing temporary architecture. In a revision view of the document, the difference that would be involved on the architecture compared with m33242_AMD (108 meeting in Valencia) is put.
The related software which improves the conformance verification is to be released as DAM study.
Since not all confomance tests are passed, it may be necessary by the next meeting to consider delaying the FDAM of the software amendment until all streams are verifying the compliance.

(This is text related to m35870.)
Title is misleading, because Amd.2 has already reached a final stage. It was discussed that it would not be a viable approach to remove existing specified FU (which would require a corrigendum, but none of the existing building blocks is wrong). Instead, it should be included in a new amendment. Provided that an SHVC related amendment can be started by the next meeting, it should be combined with that.
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51620&id_meeting=163" m35870 Miscellaneous optimizations on the dataflow description of HEVC decoder [Khaled Jerbi, Damien De Saint Jorre, Daniele Renzi, Marco Mattavelli, Claudio Alberti]
To improve the performance of the dataflow HEVC decoder, some optimizations are applied and involve modifications in the architecture. This document presents a set of optimizations applied on the intra prediction (IntraPred), the inverse integer transform (xIT), the QP generator (QP_gen) and the reconstruction (SelectCU) actors. These optimizations are currently applied on a testing temporary architecture. In a revision of the document, the difference that would be involved on the architecture compared with m33242_AMD (108 meeting in Valencia) is presented.
The document provides an alternative approach for parallel implementation of the deblocking filter which could be useful as an alternative way of implementing HEVC in parallel architectures. This could coexist with the existing approach but would also require a second configuration of FU networks for implementing HEVC.
Further clarification may be needed whether a specification of a FU for an existing standard would need to be normative (or whether additional ways of implementing it could just be given as informative examples.
It is agreed that the new proposal is useful and should be included in an upcoming amendment of 23002-4 and 23002-5. (See above under 35868.)

This contribution proposes the implementation of an event-based performance monitoring in RVC-CAL. The goal of the proposal is to provide a mechanism in RVC-CAL to analyze in detail the performance of an implementation in a processor-based platform. In order to achieve this goal, annotations are used to signal the instrumented actors and actions. To implement the proposal, the open-source Performance API (PAPI) has been integrated into ORCC - the Open-source RVC-CAL Compiler.
Extension of m28171, m31243, m33115
based on external library/API PAPI
Agreed to include it in an update of the white paper (Marco clarifies with Kyunheon whether this can be done in an editing period, or requires update at the next meeting, in latter case, we could have another draft white paper)

Correction of the P22 primaries is necessary (as the precision is insufficient).
It was concluded that this small change should be included in FDAM2 (DAM2 is curently under ballot).
Green Metadata
A joint meeting with the System SG was held Thursday 9:00-10:00. The following issues were discussed during this meeting:
Timing synchronization for carrying green metadata in AVC/HEVC SEI message.
For AVC, the FDIS of 23001-11 already contains the link to the Green SEI message hook of AVC. It was suggested for the SEI message to refer to ISO/IEC 23001-11, where the payload has been defined. It was agreed to include green metadata support in the AVC PDAM2.
For HEVC, it was planned that support should be included in DAM of SCC (June) by JCT-VC, although appropriate text for HEVC needed preparation; In order to synchronize the progression of the two specs referring each other, the amendment in 23001-11 should be started at the current meeting. The PDAM text was reviewed and approved jointly.
HYPERLINK "http://phenix.it-sudparis.eu/mpeg/doc_end_user/current_document.php?id=51530&id_meeting=163" m35780 Revised HEVC SEI Message for Green Metadata [Spencer Cheng, Jiangtao Wen]
This was reviewed in JCT-VC.
m35795 and m36024 were on best effort decoding.
m36055 is a follow-up of m35009. It gives information about the power saving and quality loss when deblocking is switched off or alternative interpolation filters are used.
Concerns were expressed that best effort decoding should not prescribe a specific non-normative decoding process. At most, metadata information should be given to a decoder that by itself then decide what to do depending on its implementation architecture. It should be demonstrated which types of metadata are benefical for such purposes. The non-normative actions to follow from these metadata should be formulated in a very generic way, e.g. not for specific interpolation filters.
m36024 is related to m36055 (subjective evaluation)
m35795 is a follow-up of m35148. No concrete proposal of metadata was provide, but this was showing the potential benefit in two hardware architectures.
Investigations on best-effort decoding is ongoing.

HDR/WCG Video Coding
See the Requirements SG report. In the joint discussion with ITU-T VCEG, they also expressed interest in the topic and in being kept informed. A CfE was issued to solicit contributions on the subject.
Future Video Coding
On behalf of the Video SG, an AHG had been set up with the goals of discussing and identifying challenges in video coding technology beyond HEVC; identifying suitable test cases and materials; and soliciting contributions on potential improvements in video compression. Another AHG on industry needs was working under requirements; the input documents on this topis are primarily related to requirement topics, but presented in a joint meeting Wed. 17-18:30; the subsequent notes reflect technical aspects that are relevant from the perspective of the Video SG
Presentation of AHG report: In the discussion about the report it is pointed out that the transport mechanisms are less relevant than the services themselves, which would be available over any types of networks; it was further mentioned that the advent of new types of sensors e.g. lightfield/plenoptic could become relevant.
Presentation of Zetacast (36097, on broadcast): new generation expected around 2025, 50% rate reduction over HEVC would be desirable
Presentation of Netflix (35771, on streaming/download) contributions: VOD at low bitrates 200-250 kbit/s, 25% rate reduction would already be attractive, encoder complexity no problem, scalability desirable for flexibility in storage and streaming, perceptual quality relevant. Netflix database still under development (4K primarily), and is intended to be provided. Perceptual evaluation/metrics ongoing, not available yet. Some 3D material also available. Scalability is denoted as important, but unclear whether there are new requirements on scalability? It is mentioned that SHVC is not attractive for the kind of flexible scalability Netflix would desire. Challenges for low bit rate over some networks - Current rate range is from 200 kbit/s (480p) up to 16 Mbit/s (4K).
In the joint discussion with ITU-T VCEG, both groups expressed interest in studying future video coding techniques and in communicating with each other about the subject.
In a follow-up meeting Thu 10-11, next steps towards future video coding standardization were determined as follows (see N15272):
Look around for new solutions
Document to solicit contributions on improved compression (request for demonstration of technology that improves compression beyond HEVC for traditional (e.g. HEVC CTC) or innovative use cases) Output from Video (N15273)
Study on new capturing technologies - AHG
Workshop about new video compression and capturing technologies (Lucca) - AHG
List a short and meaningful list of requirements
Solicit contributions on open problems in video usages - AHG
Identify new challenges brought by this - AHG
Start developing a lean and meaningful document Output from Requirements (N15090)
Define test material and test cases
Issue request for test material (resolution) - AHG
New material to include professional and user generated content
Establish an environment for people to share experiences
Develop an experimentation platform based on HM16.3|4 (mention in video doc & AHG)
Potentially there may be other platforms in the future depending on submissions
Other issues
Restructuring of 14496-4 and 14496-5 remains planned.
Wednesday Video plenary status review
A Video subgroup plenary was held 12:00-13:00 on Wednesday. Reports of BoGs were given as follows:
MPEG-7 Visual:
Input on conformance was discussed, investigation planned on how loosening the conformance would affect the matching performance (out this into AHG mandates)
Issuing the CD of part 6 second edition
Clarify whether the descriptors which are not having reference implementation are in any profiles (Stavros reports back)
CDVS:
Software improvements are being accepted for WD3
New TM document (13) will be issued, with timeline
Conformance to be reviewed, independent implementation is investigated. Eventually consider describing the planned experimention in an output doc
Initial planning of awareness event. 3 demos confirmed. External speakers about potential applications?
BoG meets again from 14:00
IVC:
Prepare BD rate figures using HP as anchor
Issue resolution that the progress in IVC becoming close to HP performance is exciting, and plan a visual comparison against high profile by next meeting to make further decision of progressing this into a work item
Clarify whether HP anchors should be regenerated .Alexis Tourapis expressed some willingness to do that, but final clarification could not be reached until the meeting closed. To be further clarified in AHG during the preparation of the IVC viewing for the 112th meeting.
Technical review of new contributions:
Bug report on ME (encoder only) approved by Video plenary
RDOQ for chroma (encoder only) approved by Video plenary
Reference frame set improvement (likely normative however does not require changing the signaling), needs further assessment about prior art. This was revisited Thu 11:30 Agreed that this likely covered by sufficiently old prior art. It was however pointed out that the new mechanism of storing some older reference pictures would increase the decoded picture buffer significantly, such that further investigation should be performed how this could be reduced. In terms of complexity of a video coding implementation it would not be desirable. Adoption to ITM 12 approved by video plenary.
Loop filtering (normative change using more pixels) it is claimed that the expired patent which covers the loop filter is not related to the number of pixels and the new method of decision. Further investigation was performed in the BoG, with revisit in Video Thu 11:30. During this discussion some concern was expressed whether the strong filtering which also modifies pixels q1/p1 and q2/p2 is covered by the prior art of the expired patent, whereas the decision/threshold criteria are assessed to be covered. During the Friday plenary, more evidence was brought that the prior art does not restrict modifications of pixels within the block adoption approved by Video plenary
Temporal dependent RDO (non-normative) approved by Video plenary
Fuzzy rate control (non-normative) approved by Video plenary (but not to be used in the visual comparison which should be without rate control)
Overall improvement may be in range of 1% for RA, 2% for LD
BoG continues Wed 13:00
Follow-up dicussion in video plenary on Thu 11:30
Reported that average BR incease of ITM11 versus AVC HP is 11/10.6% for RA/LD cases.
VCB:
Further review of the work so far Wed 15:00, presentation of documents, suggested improvements of the type-3 investigation to turn it into an output doc.
RVC:
Reviewed Wed 14:00
Closing plenary topics
A closing plenary of the Video subgroup was held Friday 9:0011:00. Output docs were approved, and AHGs were established. Discussions are recorded in this section.
All issues regarding breakout activities are basically reflected in the respective subsections about BoG activities above.
CDVS:
Conformance testing was further discussed, a new contribution was brought with different encoder implementation (from scratch). Divergences in detection and matching of keypoint was found, further investigation necessary. Conformance testing tool was implemented. No document is needed.
Some further cleanups in reference software needed before going to CD.
Awareness event: Planning of output with 3 weeks editing period, presentations on CDVS scope, technology, applications planned (only internal speakers), 5 demos confirmed.
IVC:
Further investigation had been made on the issue of the strong deblocking filter proposed in m35786. It is confirmed that the prior art (expired patent) does not restrict the number of pixels to be modified.
New EE6 on multiple reference frames.
The Video plenary was closed Friday 02-20, 11:02.
Output docs
During the closing plenary, the following output documents were recommended for approval by the Video subgroup (including information about publication status and editing periods).

JCT-VC report
Source: Jens Ohm and Gary Sullivan, Chairs
Summary
The Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T WP3/16 and ISO/IEC JTC 1/ SC 29/ WG 11 held its twentieth meeting during 1017 Feb. 2015 at the ITU-T premises in Geneva, CH. The JCT-VC meeting was held under the chairmanship of Dr Gary Sullivan (Microsoft/USA) and Dr Jens-Rainer Ohm (RWTH Aachen/Germany). For rapid access to particular topics in this report, a subject categorization is found (with hyperlinks) in section REF _Ref298716123 \r \h 1.14 of this document.
The JCT-VC meeting sessions began at approximately 0930 hours on Tuesday 10 Feb. 2015. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 1400 hours on Tuesday 17 Feb. 2015. Approximately 120 people attended the JCT-VC meeting, and approximately 200 input documents were discussed. The meeting took place in a collocated fashion with a meeting of ITU-T SG16 one of the two parent bodies of the JCT-VC. The subject matter of the JCT-VC meeting activities consisted of work on the video coding standardization project known as High Efficiency Video Coding (HEVC) and its extensions.
One primary goal of the meeting was to review the work that was performed in the interim period since the nineteenth JCT-VC meeting in producing:
The HEVC test model (HM) 16 improved encoder description (including RExt modifications);
HEVC Defect Report for conformance testing (for Version 1);
The RExt draft verification test plan (including some testing of version 1 for interlaced video);
The RExt reference software draft 1 and conformance testing draft 3;
The SHVC conformance testing draft 1 and test model 8;
For HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 3, SCC draft text 2, and a document specifying common test conditions and software reference configurations for SCC experiments.
The other most important goals were to review the results from three Core Experiments on Screen Content Coding (CE13), and review other technical input documents. Reviewing the progress made towards definition of screen content coding tools was the most important topic of the meeting. Advancing the work on development of conformance and reference software for recently finalized HEVC extensions (RExt, SHVC) is also a significant goal. Further preparation of verification tests was conducted. Possible needs for corrections to version 2 were also considered.
In addition to 2 new experiment plan descriptions in screen content coding, the JCT-VC produced 10 other particularly important output documents from the meeting:
The HEVC test model (HM) 16 update 2 improved encoder description (including RExt modifications);
Verification test plan for format range extensions and interlaced video;
The RExt reference software draft 2 and conformance testing draft 4, the latter being combined with improved version 1 conformance testing ;
The SHVC reference software draft 1, conformance testing draft 2 and SHM test model 9;
For HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 4, SCC draft text 3, and a document specifying common test conditions and software reference configurations for SCC experiments.
For the organization and planning of its future work, the JCT-VC established 13 "ad hoc groups" (AHGs) to progress the work on particular subject areas. The next four JCT-VC meetings were planned for Fri. 19 Fri. 26 June 2015 under WG 11 auspices in Warsaw, PL, Wed. 14 Wed. 21 Oct. 2015 under ITU-T auspices in Lucca, IT, Fri. 19 Fri. 26 Feb. 2016 under WG 11 auspices in San Diego, US, and Wed. 25 May Wed. 1 June 2016 under ITU-T auspices in Geneva, CH.

Organization
The ITU-T/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) is a group of video coding experts from the ITU-T Study Group 16 Visual Coding Experts Group (VCEG) and the ISO/IEC JTC 1/ SC 29/ WG 11 Moving Picture Experts Group (MPEG). The parent bodies of the JCT-VC are ITU-T WP3/16 and ISO/IEC JTC 1/SC 29/WG 11.
The Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T WP3/16 and ISO/IEC JTC 1/ SC 29/ WG 11 held its twentieth meeting during 1017 Feb. 2015 at the ITU-T premises in Geneva, CH. The JCT-VC meeting was held under the chairmanship of Dr Gary Sullivan (Microsoft/USA) and Dr Jens-Rainer Ohm (RWTH Aachen/Germany).
Meeting logistics
The JCT-VC meeting sessions began at approximately 0930 hours on Tuesday 10 Feb. 2015. Meeting sessions were held on all days (including weekend days) until the meeting was closed at approximately 1400 hours on Tuesday 17 Feb. 2015. Approximately 120 people attended the JCT-VC meeting, and approximately 200 input documents were discussed. The meeting took place in a collocated fashion with a meeting of WG11 one of the two parent bodies of the JCT-VC. The subject matter of the JCT-VC meeting activities consisted of work on the video coding standardization project known as High Efficiency Video Coding (HEVC) and its extensions.

Information regarding logistics arrangements for the meeting had been provided via the email reflector HYPERLINK "mailto:jct-vc@lists.rwth-aachen.de" jct-vc@lists.rwth-aachen.de and at HYPERLINK "http://wftp3.itu.int/av-arch/jctvc-site/2015_02_T_Geneva/" http://wftp3.itu.int/av-arch/jctvc-site/2015_02_T_Geneva/.
Primary goals
One primary goal of the meeting was to review the work that was performed in the interim period since the nineteenth JCT-VC meeting in producing:
The HEVC test model (HM) 16 improved encoder description (including RExt modifications);
HEVC Defect Report for conformance testing (for Version 1);
The RExt draft verification test plan (including some testing of version 1 for interlaced video);
The RExt reference software draft 1 and conformance testing draft 3;
The SHVC conformance testing draft 1 and test model 8;
For HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 3, SCC draft text 2, and a document specifying common test conditions and software reference configurations for SCC experiments.
The other most important goals were to review the results from three Core Experiments on Screen Content Coding (CE13), and review other technical input documents. Reviewing the progress made towards definition of screen content coding tools was the most important topic of the meeting. Advancing the work on development of conformance and reference software for recently finalized HEVC extensions (RExt, SHVC) is also a significant goal. Further preparation of verification tests was conducted. Possible needs for corrections to version 2 were also considered.
Documents and document handling considerations
General
The documents of the JCT-VC meeting are listed in Annex A of this report. The documents can be found at HYPERLINK "http://phenix.it-sudparis.eu/jct/" http://phenix.it-sudparis.eu/jct/.
Registration timestamps, initial upload timestamps, and final upload timestamps are listed in Annex A of this report (as of the time of preparation of this report).
The document registration and upload times and dates listed in Annex A and in headings for documents in this report are in Paris/Geneva time. Dates mentioned for purposes of describing events at the meeting (other than as contribution registration and upload times) follow the local time at the meeting facility.
Highlighting of recorded decisions in this report:
Decisions made by the group that affect the normative content of the draft standard are identified in this report by prefixing the description of the decision with the string "Decision:".
Decisions that affect the reference software but have no normative effect on the text are marked by the string "Decision (SW):".
Decisions that fix a "bug" in the specification (an error, oversight, or messiness) are marked by the string "Decision (BF):".
Decisions regarding things that correct the text to properly reflect the design intent, add supplemental remarks to the text, or clarify the text are marked by the string "Decision (Ed.):".
Decisions regarding simplification or improvement of design consistency are marked by the string "Decision (Simp.):".
Decisions regarding complexity reduction (in terms of processing cycles, memory capacity, memory bandwidth, line buffers, number of entropy-coding contexts, number of context-coded bins, etc.)
"Decision (Compl.):".
This meeting report is based primarily on notes taken by the chairs and projected for real-time review by the participants during the meeting discussions. The preliminary notes were also circulated publicly by ftp during the meeting on a daily basis. Considering the high workload of this meeting and the large number of contributions, it should be understood by the reader that 1) some notes may appear in abbreviated form, 2) summaries of the content of contributions are often based on abstracts provided by contributing proponents without an intent to imply endorsement of the views expressed therein, and 3) the depth of discussion of the content of the various contributions in this report is not uniform. Generally, the report is written to include as much discussion of the contributions and discussions as is feasible (in the interest of aiding study), although this approach may not result in the most polished output report.
Late and incomplete document considerations
The formal deadline for registering and uploading non-administrative contributions had been announced as Friday, 30 Jan. 2015.
Non-administrative documents uploaded after 2359 hours in Paris/Geneva time Saturday 31 Jan. 2015 were considered "officially late".
Most documents in the "late" category were CE reports or cross-verification reports, which are somewhat less problematic than late proposals for new action (and especially for new normative standardization action).
At this meeting, we again had a substantial amount of late document activity, but in general the early document deadline gave a significantly better chance for thorough study of documents that were delivered in a timely fashion. The group strived to be conservative when discussing and considering the content of late documents, although no objections were raised regarding allowing some discussion in such cases.
All contribution documents with registration numbers JCTVC-T0139 and higher were registered after the "officially late" deadline (and therefore were also uploaded late). However, some documents in the "T0139+" range include break-out activity reports that were generated during the meeting, and are therefore better considered as report documents rather than as late contributions.
In many cases, contributions were also revised after the initial version was uploaded. The contribution document archive website retains publicly-accessible prior versions in such cases. The timing of late document availability for contributions is generally noted in the section discussing each contribution in this report.
One suggestion to assist with the issue of late submissions was to require the submitters of late contributions and late revisions to describe the characteristics of the late or revised (or missing) material at the beginning of discussion of the contribution. This was agreed to be a helpful approach to be followed at the meeting.
The following other technical design proposal contributions were registered on time but were uploaded late:
JCTVC-T0124 (a proposal on CE1 Test C.1: 2-D Index Map Coding of Palette Mode in HEVC SCC) [uploaded 02-01]
JCTVC-T0125 (a proposal on CE3 Test B.1: Adaptive Scan Directions in HEVC SCC) [uploaded 02-01]
JCTVC-T0126 (a proposal on CE3 Test B.3: 2-D Intra String Copy in HEVC SCC) [uploaded 02-01]
JCTVC-T0138 (a proposal on Copy mode for static screen content coding) [uploaded 02-02]
The following other documents not proposing normative technical content were registered on time but were uploaded late:
JCTVC-T0031 (a document proposing editorial improvements to HEVC Screen Context Coding Draft Text 2) [uploaded 02-11]
JCTVC-T0104 (a document analyzing coding performance for HEVC with denoising) [uploaded 02-16]
The following cross-verification reports were registered on time but were uploaded late: JCTVC-T0032 [uploaded 02-10], JCTVC-T0033 [uploaded 02-03], JCTVC-T0085 [uploaded 02-01], JCTVC-T0100 [uploaded 02-04], JCTVC-T0107 [uploaded 02-10], JCTVC-T0108 [uploaded 02-10], JCTVC-T0115 [uploaded 02-06], JCTVC-T0130 [uploaded 02-02], JCTVC-T0131 [uploaded 02-03].
The following contribution registrations were later cancelled, withdrawn, never provided, were cross-checks of a withdrawn contribution, or were registered in error: JCTVC-T0093, JCTVC-T0205, JCTVC-T0211, JCTVC-T0221, JCTVC-T0226, and JCTVC-T0232.
Ad hoc group interim activity reports, CE summary results reports, break-out activity reports, and information documents containing the results of experiments requested during the meeting are not included in the above list, as these are considered administrative report documents to which the uploading deadline is not applied.
As a general policy, missing documents were not to be presented, and late documents (and substantial revisions) could only be presented when sufficient time for studying was given after the upload. Again, an exception is applied for AHG reports, CE summaries, and other such reports which can only be produced after the availability of other input documents. There were no objections raised by the group regarding presentation of late contributions, although there was some expression of annoyance and remarks on the difficulty of dealing with late contributions and late revisions.
It was remarked that documents that are substantially revised after the initial upload are also a problem, as this becomes confusing, interferes with study, and puts an extra burden on synchronization of the discussion. This is especially a problem in cases where the initial upload is clearly incomplete, and in cases where it is difficult to figure out what parts were changed in a revision. For document contributions, revision marking is very helpful to indicate what has been changed. Also, the "comments" field on the web site can be used to indicate what is different in a revision.
"Placeholder" contribution documents that were basically empty of content, with perhaps only a brief abstract and some expression of an intent to provide a more complete submission as a revision, were considered unacceptable and were to be rejected in the document management system, as has been agreed since the third meeting.
The following case did not occur at the 20th meeting: The initial uploads of the following contribution documents were rejected as a "placeholders" without any significant content and were not corrected until after the upload deadline:
JCTVC-T0XXX (a proposal on
, corrected by a late upload on 02-XX)
A few contributions had some problems relating to IPR declarations in the initial uploaded versions (missing declarations, declarations saying they were from the wrong companies, etc.). These issues were corrected by later uploaded versions in a reasonably timely fashion in all cases (to the extent of the awareness of the chairs).
Some other errors were noticed in other initial document uploads (wrong document numbers in headers, etc.) which were generally sorted out in a reasonably timely fashion. The document web site contains an archive of each upload.
Measures to facilitate the consideration of contributions
It was agreed that, due to the continuingly high workload for this meeting, the group would try to rely extensively on summary CE reports. For other contributions, it was agreed that generally presentations should not exceed 5 minutes to achieve a basic understanding of a proposal with further review only if requested by the group. For cross-verification contributions, it was agreed that the group would ordinarily only review cross-checks for proposals that appear promising.
When considering cross-check contributions, it was agreed that, to the extent feasible, the following data should be collected:
Subject (including document number).
Whether common conditions were followed.
Whether the results are complete.
Whether the results match those reported by the contributor (within reasonable limits, such as minor compiler/platform differences).
Whether the contributor studied the algorithm and software closely and has demonstrated adequate knowledge of the technology.
Whether the contributor independently implemented the proposed technology feature, or at least compiled the software themselves.
Any special comments and observations made by a cross-check contributor.
Outputs of the preceding meeting
The output documents of the previous meeting, particularly including the meeting report JCTVC-S1000, the improved HEVC Test Model 16 (HM16) JCTVC-S1002, the Draft Verification Test Plan for RExt and interlaced coding with version 1, JCTVC-S1003, the Version 1 Conformance Defect Report JCTVC-S1004, the RExt Reference Software JCTVC-S1011, the RExt Conformance Testing Draft 3 JCTVC-S1012, the SHVC test model 8 (SHM8) JCTVC-S1007, the SHVC Conformance Testing Draft 1 JCTVC-S1008, the Screen Content Coding (SCC) Draft Text 2 JCTVC-S1005, the SCC test model 3 JCTVC-S1014, and the common test conditions for SCC (JCTVC-S1015) were approved. The HM reference software and its extensions for RExt, SHVC and SCC were also approved.
The group had initially been asked to review the prior meeting report for finalization. The meeting report was later approved without modification.
All output documents of the previous meeting and the software had been made available in a reasonably timely fashion.
The chairs asked if there were any issues regarding potential mismatches between perceived technical content prior to adoption and later integration efforts. It was also asked whether there was adequate clarity of precise description of the technology in the associated proposal contributions.
It was remarked that, in regard to software development efforts for cases where "code cleanup" is a goal as well as integration of some intentional functional modification, it was emphasized that these two efforts should be conducted in separate integrations, so that it is possible to understand what is happening and to inspect the intentional functional modifications.
The need for establishing good communication with the software coordinators was also emphasized.
At some previous meetings, it had been remarked that in some cases the software implementation of adopted proposals revealed that the description that had been the basis of the adoption apparently was not precise enough, so that the software unveiled details that were not known before (except possibly for CE participants who had studied the software). Also, there should be time to study combinations of different adopted tools with more detail prior to adoption.
CE descriptions need to be fully precise this is intended as a method of enabling full study and testing of a specific technology.
Greater discipline in terms of what can be established as a CE may be an approach to helping with such issues. CEs should be more focused on testing just a few specific things, and the description should precisely define what is intended to be tested (available by the end of the meeting when the CE plan is approved).
It was noted that sometimes there is a problem of needing to look up other referenced documents, sometimes through multiple levels of linked references, to understand what technology is being discussed in a contribution and that this often seems to happen with CE documents. It was emphasized that we need to have some reasonably understandable description, within a document, of what it is talking about.
Software study can be a useful and important element of adequate study; however, software availability is not a proper substitute for document clarity.
Software shared for CE purposes needs to be available with adequate time for study. Software of CEs should be available early, to enable close study by cross-checkers (not just provided shortly before the document upload deadline).
Issues of combinations between different features (e.g., different adopted features) also tend to sometimes arise in the work.

IPR policy reminder
Participants were reminded of the IPR policy established by the parent organizations of the JCT-VC and were referred to the parent body websites for further information. The IPR policy was summarized for the participants.
The ITU-T/ITU-R/ISO/IEC common patent policy shall apply. Participants were particularly reminded that contributions proposing normative technical content shall contain a non-binding informal notice of whether the submitter may have patent rights that would be necessary for implementation of the resulting standard. The notice shall indicate the category of anticipated licensing terms according to the ITU-T/ITU-R/ISO/IEC patent statement and licensing declaration form.
This obligation is supplemental to, and does not replace, any existing obligations of parties to submit formal IPR declarations to ITU-T/ITU-R/ISO/IEC.
Participants were also reminded of the need to formally report patent rights to the top-level parent bodies (using the common reporting form found on the database listed below) and to make verbal and/or document IPR reports within the JCT-VC as necessary in the event that they are aware of unreported patents that are essential to implementation of a standard or of a draft standard under development.

It is noted that the ITU TSB director's AHG on IPR had issued a clarification of the IPR reporting process for ITU-T standards, as follows, per SG 16 TD 327 (GEN/16):
"TSB has reported to the TSB Director's IPR Ad Hoc Group that they are receiving Patent Statement and Licensing Declaration forms regarding technology submitted in Contributions that may not yet be incorporated in a draft new or revised Recommendation. The IPR Ad Hoc Group observes that, while disclosure of patent information is strongly encouraged as early as possible, the premature submission of Patent Statement and Licensing Declaration forms is not an appropriate tool for such purpose.
In cases where a contributor wishes to disclose patents related to technology in Contributions, this can be done in the Contributions themselves, or informed verbally or otherwise in written form to the technical group (e.g. a Rapporteur's group), disclosure which should then be duly noted in the meeting report for future reference and record keeping.
It should be noted that the TSB may not be able to meaningfully classify Patent Statement and Licensing Declaration forms for technology in Contributions, since sometimes there are no means to identify the exact work item to which the disclosure applies, or there is no way to ascertain whether the proposal in a Contribution would be adopted into a draft Recommendation.
Therefore, patent holders should submit the Patent Statement and Licensing Declaration form at the time the patent holder believes that the patent is essential to the implementation of a draft or approved Recommendation."
The chairs invited participants to make any necessary verbal reports of previously-unreported IPR in draft standards under preparation, and opened the floor for such reports: No such verbal reports were made.
Software copyright disclaimer header reminder
It was noted that, as had been agreed at the 5th meeting of the JCT-VC and approved by both parent bodies at their collocated meetings at that time, the HEVC reference software copyright license header language is the BSD license with preceding sentence declaring that contributor or third party rights are not granted, as recorded in N10791 of the 89th meeting of ISO/IEC JTC 1/ SC 29/ WG 11. Both ITU and ISO/IEC will be identified in the and tags in the header. This software is used in the process of designing the HEVC standard and its extensions, and for evaluating proposals for technology to be included in the design. After finalization of the draft (current version JCTVC-M1010), the software will be published by ITU-T and ISO/IEC as an example implementation of the HEVC standard and for use as the basis of products to promote adoption of the technology.
Different copyright statements shall not be committed to the committee software repository (in the absence of subsequent review and approval of any such actions). As noted previously, it must be further understood that any initially-adopted such copyright header statement language could further change in response to new information and guidance on the subject in the future.
Communication practices
The documents for the meeting can be found at HYPERLINK "http://phenix.it-sudparis.eu/jct/" http://phenix.it-sudparis.eu/jct/. For the first two JCT-VC meetings, the JCT-VC documents had been made available at HYPERLINK "http://ftp3.itu.int/av-arch/jctvc-site"http://ftp3.itu.int/av-arch/jctvc-site, and documents for the first two JCT-VC meetings remain archived there as well. That site was also used for distribution of the contribution document template and circulation of drafts of this meeting report.
The JCT-VC email list is managed through HYPERLINK "https://mailman.rwth-aachen.de/mailman/options/jct-vc" https://mailman.rwth-aachen.de/mailman/options/jct-vc, and to send email to the reflector, the email address is HYPERLINK "mailto:jct-vc@lists.rwth-aachen.de"jct-vc@lists.rwth-aachen.de. Only members of the reflector can send email to the list. However, membership of the reflector is not limited to qualified JCT-VC participants.
It was emphasized that reflector subscriptions and email sent to the reflector must use real names when subscribing and sending messages and subscribers must respond to inquiries regarding the nature of their interest in the work.
It was emphasized that usually discussions concerning CEs and AHGs should be performed using the reflector. CE internal discussions should primarily be concerned with organizational issues. Substantial technical issues that are not reflected by the original CE plan should be openly discussed on the reflector. Any new developments that are result of private communication cannot be considered to be the result of the CE.
For the case of CE documents and AHG reports, email addresses of participants and contributors may be obscured or absent (and will be on request), although these will be available (in human readable format possibly with some "obscurification") for primary CE coordinators and AHG chairs.

AHG reports (15)
The activities of ad hoc groups (AHGs) that had been established at the prior meeting are discussed in this section.
(Consideration of these reports was chaired by GJS & JRO on Tuesday 02-10, 0930-1300, except as noted.)
HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9979" JCTVC-T0001 JCT-VC AHG report: Project management (AHG1) [ HYPERLINK "mailto:garysull@microsoft.com" G. J. Sullivan, HYPERLINK "mailto:ohm@ient.rwth-aachen.de" J.-R. Ohm]
This document reports on the work of the JCT-VC ad hoc group on Project Management, including an overall status report on the project and the progress made during the interim period since the preceding meeting.
In the interim period since the 19th JCT-VC meeting, the following (14) documents had been produced:
HEVC test model (HM) 16 improved encoder description (including RExt modifications),
HEVC conformance testing defect report (for Version 1),
RExt draft verification test plan (including some testing of version 1 for interlaced video),
RExt reference software draft 1 and conformance testing draft 3,
SHVC conformance testing draft 1 and test model 8;
For HEVC screen content coding (SCC) extensions, the HEVC screen content coding test model 3, SCC draft text 2, and a document specifying common test conditions and software reference configurations for SCC experiments.
Finalized versions of three Core Experiment reports for SCC (CE1: Improvements of palette mode, CE2: Intra block copy relationship to inter coding, and CE3: Intra Line Copy and Intra String Copy)
Furthermore, three Core Experiments on screen content coding tools (CE1, 2, 3) were run. Advancing the work on development of conformance and reference software for HEVC extensions was also a significant goal.
The work of the JCT-VC overall had proceeded well and actively in the interim period with a considerable number of input documents to the current meeting. Active discussion had been carried out on the group email reflector (which had 1729 subscribers as of 2015-02-09), and the output documents from the preceding meeting had been produced.
Except as noted below, output documents from the preceding meeting had been made available at the "Phenix" site (http://phenix.it-sudparis.eu/jct/) or the ITU-based JCT-VC site (http://wftp3.itu.int/av-arch/jctvc-site/2015_02_T_Geneva/ ), particularly including the following:

The fifteen ad hoc groups and the three core experiments had made progress, and various reports from those activities had been submitted.
The different software modules (HM16.3, SHM8.0 and SCM3.0) had been prepared and released with appropriate updates approximately as scheduled. Both SHM and SCM are implemented as branches from HM16.
Since the approval of software copyright header language at the March 2011 parent-body meetings, that topic seems to be resolved.
Released versions of the software are available on the SVN server at the following URL:
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/version_number,
where version_number corresponds to one of the versions described below e.g., HM-16.3.
Intermediate code submissions can be found on a variety of branches available at:
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/branches/branch_name,
where branch_name corresponds to a branch (eg., HM-16.3-dev).
Various problem reports relating to asserted bugs in the software, draft specification text, and reference encoder description had been submitted to an informal "bug tracking" system (https://hevc.hhi.fraunhofer.de/trac/hevc). That system is not intended as a replacement of our ordinary contribution submission process. However, the bug tracking system was considered to have been helpful to the software coordinators and text editors. The bug tracker reports had been automatically forwarded to the group email reflector, where the issues were discussed and this is reported to have been helpful. It was noted that contributions had generally been submitted that were relevant to resolving the more difficult cases that might require further review.
The ftp site at ITU-T is used to exchange draft conformance testing bitstreams. The ftp site for downloading bitstreams is http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/.
A spreadsheet to summarize the status of bitstream exchange, conformance bitstream generation is available in the same directory. It includes the list of bitstreams, codec features and settings, and status of verification.
Approximately 200 input contributions to the current meeting had been registered. A significant number of late-registered and late-uploaded contributions were noted, even though most were cross-check documents.
A preliminary basis for the document subject allocation and meeting notes for the 20th meeting had been circulated to the participants by being announced in email, and was publicly available on the ITU-hosted ftp site.

This document reports the work of the JCT-VC ad hoc group on HEVC test model editing and errata reporting (AHG2) between the 19th meeting in Strasbourg, FR (October 2014) and the 20th meeting in Geneva, CH (February 2015).
An issue tracker (https://hevc.hhi.fraunhofer.de/trac/hevc) was used in order to facilitate the reporting of errata with the HEVC documents.
The High Efficiency Video Coding (HEVC) Test Model 16 (HM 16) Improved Encoder Description was published as JCTVC-S1002. This document represented a refinement of the previous HM16 Encoder Description document (JCTVC-R1002). In particular, numerous tool descriptions were improved and command-line description separated out, due to the availability of the HM software manual. The resultant document provides a source of general tutorial information on HEVC Edition 1 and Range Extensions, together with an encoder-side description of the HM-16 software.
A list of bug fixes for HEVC Edition 2 provided by some of the editors of HEVC Edition 2 was collected and included in the attachment.
The report included a text attachment that listed a number of issues and contained some fixes.
Additional topics mentioned in the report included
Clarity of the text in relation to profile specifications for ross_component_prediction_enabled_flag and related high-level syntax elements.
Some minor indexing issues
The issues seemed to be generally rather minor.
It was agreed that corrections can just be integrated into the screen content coding amendment/revision.
The recommendations of the HEVC test model editing and errata reporting AHG are for JCT-VC to:
Encourage the use of the issue tracker to report issues with the text of both the HEVC specification and the Encoder Description
Identify and resolve any residual issues relating to mismatches between software and text
Review the above reported discussions and conclude whether and what changes should be made to the HEVC version 2 specification
Review the list of bug fixes collected for HEVC Edition 2, and include all confirmed bug fixes, including the outcome of the above items, if any, into a JCT-VC output document for the purpose of HEVC Edition 2 defect reporting

(Consideration of this report was chaired by GJS and JRO on Saturday 02-14 p.m.)
This report summarizes the activities of the AhG on HEVC HM software development and software technical evaluation that have taken place between the 19th and 20th JCT-VC meetings. Activities focused on software maintenance, i.e. code tidying and fixing bugs.
A brief summary of activities related to each mandate is given below.
No software changes were adopted at the previous meeting. Thus, only bug fixes and cleanups were addressed. The distribution of the software was made available through the SVN server set up at HHI, as announced on the JCT-VC email reflector.
The HM user manual has been updated and a version controlled copy is included in the doc directory of the repository. A PDF version has been produced and is included in the same location prior to each HM release.
Version 16.3 was released on Feb. 6, 2015. A number of bugs have been identified and fixed.
There are a number of reported software bugs that should be fixed.
A detailed history of all changes made to the software can be viewed at https://hevc.hhi.fraunhofer.de/trac/hevc/timeline.
Released versions of the software are available on the SVN server at the following URL:
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/version_number,
where version_number corresponds to one of the versions described below (eg., HM-16.0). Intermediate code submissions based on previous versions can be found on a variety of branches available at:
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/branches/branch_name,
where branch_name corresponds to a branch (eg., HM-11.0-dev).
Current development has been moved into a single development branch at
https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/branches/HM-dev
HM 16.3 was released on Feb 6, 2015. A major change is that copies of parameter sets are stored with every decoded picture. This avoids references to invalid parameter sets while filtering or output, when parameter sets have been overwritten with changed parameters. In the process the code has been cleaned up declaring the parameter sets 'const' to avoid accidental change. The release also includes many other bug-fixes. A list of closed bug tracker items can be found at:
https://hevc.hhi.fraunhofer.de/trac/hevc/query?status=closed&group=resolution&milestone=HM-16.3
There are no coding performance changes between HM16.3 and HM16.2.
HM 16.4 is planned to be released during or shortly after the 20th JCT-VC meeting. Work is progressing on cleaning up SEI writing functionality.
Unless the release has been tagged, the development branch can be found under
HYPERLINK "https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/branches/HM-dev" https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/branches/HM-dev
Changes to common test conditions were proposed in JCTVC-S0090. Early versions of the meeting notes were not fully clear, whether the changed GOP structure was adopted for the additional configuration example with temporal scalability, or whether the HEVC version 1 common test conditions were supposed to be changed to include temporal scalability and the new reference structure.
Additional testing on the coding performance has been conducted after the meeting showing some loss.
The common test condition files have not been changed and the issue was left for discussion at the next JCT-VC meeting. The following note was added to the meeting report:
"Post-meeting note: Further testing to confirm the described results was conducted after the meeting by the software coordinator (K. Sühring). In the context of HM 16.2, the modified referencing structure reportedly showed an average 0.3% loss relative to the ordinary random access configuration for the HM, with peak loss (on the sequence "SteamLocomotive") being 2.1% (Main) or 2.2% (Main 10). There was a reported general tendency for higher resolutions to have somewhat larger losses than for lower resolutions. Since the reported loss, while still minor, was larger than what was expected from the discussion at the meeting, the example random access configuration for the HM was not replaced pending future discussion to determine whether the measured loss is acceptable. (Only the example temporal scalability configuration was replaced for the HM distribution.)"
The following table shows coding the performance change for random access compared to the current CTC GOP; both based on HM-16.2:
Random Access MainRandom Access HE10YUVYUVClass A0.9%0.0%"0.1%1.0%0.4%0.1%Class B0.4%"0.1%"0.1%0.4%0.2%0.2%Class C0.0%0.0%0.1%0.0%0.1%0.3%Class D"0.1%0.0%0.1%"0.1%"0.1%"0.1%Class EOverall0.3%0.0%0.0%0.3%0.1%0.1%0.3%0.0%"0.1%0.4%0.1%0.1%Class F0.2%0.3%0.2%0.2%0.2%0.2%
The following comparisons were provided as Excel sheets:
HM-16.2+fix+S0090_vs_HM_16.2: The reference structure proposed in JCTVC-S0090 compared to CTC
HM-16.2+fix+S0090_vs_HM_16.2+fix+tid: The reference structure proposed in JCTVC-S0090 compared to the example file for temporal scalability (which is included in the "misc" folder of the HM software)
HM-16.2+fix+tid_vs_HM_16.2: The example file for temporal scalability (which is included in the "misc" folder of the HM software) compared to CTC
Note: JCTVC-S0090 includes a software fix related to handling of pictures on different temporal sub-layers. The fix has been applied to the software for all configurations that use temporal sub-layers.
There was discussion about the potential change of CTC for RA, such that temporal scalability would be supported. This leads to average bit rate increase of 0.3% and maximum around 2% (for steam locomotive).
In the discussion, a participant commented that the difference in performance between the new temporally nested and the non-nested configuration examples is very small ("0.1 to 1%, depending on sequence class, 0.3% overall average as tested), which was said to not really justify providing different configuration examples. It was also asserted that having the ordinary RA example use temporal scalability is desirable for showing this feature of the design.
Decision (SW): Agreed to change the CTC in HM 16.4 such that temporal scalability is supported in the RA test conditions (version 1 and all extensions RExt/SCC/SHM).
There is an on-going issue regarding the bit-range of inputs to CCP, first reported on the bug-tracker as ticket 1321 (https://hevc.hhi.fraunhofer.de/trac/hevc/ticket/1321).
HM uses 16-bit Pels to store data at the output of the inverse transform, unless high-bit-depth support is enabled (as required for above 12-bit operation), which then uses 32-bit Pels. It was noticed that with engineered bitstreams, a different result was obtained from using the version of HM with high-bit-depth-support enabled versus the version with high-bit-depth-support disabled. This was determined to be due to the inputs of the inverse-CCP been prematurely truncated to fit within the 16-bit Pel type. This behaviour had not been seen before with encoder-generated bitstreams.
The aim is that a suitable constraint can be added to the specification that will not hinder any real encoders on the market, but reduce the sizes of intermediate values and internal buffers caused by engineered/evil bitstreams. It is hoped that these intermediates can continue to be represented within the more software/processor-friendly 16-bit Pel types.
This issue was discussed at the previous JCT-VC meeting in Strasbourg and it was agreed that a constraint could be added to the next version of the HEVC specification. (However, it was not yet incorporated into a draft text output document.)
The initial constraint proposed at the previous meeting (which limits inputs to the range of the quantized coefficients CoeffMinY/C to CoeffMaxY/C) has been found to be problematic when coding 16 bit video with extended precision disabled. For example, this constraint would impact the use of CCP in lossless coding of 16-bit data for a normal encoder, since such an encoder would be expected to produce lossless residuals at the output of inverse-CCP of 17 bit (16-bit+sign). However, it was remarked that it doesn't really seem sensible to try to encode high bit depth data with extended precision disabled.
An alternative constraint was later suggested on the bug tracker (constrain inputs to bitDepthY/C+4 bits). This keeps data below 16-bit (preferable for software implementations, such as HM) for 12-bit profiles (and below), and does not impede the operation of CCP above 12-bit.
JCT-VC T0132 also discusses other alternative limit methods.
This issue was further discussed chaired by GJS on Monday 02-16 p.m.
Decision: As previously planned, for RExt purposes, specify a normative constraint that limits inputs to the inverse CCP to the range of the quantized coefficients CoeffMinY/C to CoeffMaxY/C. (Include in SCC draft output.)
The bug trackers for HEVC and the SHVC, MV-HEVC and 3D-HEVC extensions have been in the focus of spam robots. Additional measures have been deployed to prevent posting of spam into tickets and wiki pages (which could result in reflector messages), including:
Registration is only available through the HEVC main bug tracker at
https://hevc.hhi.fraunhofer.de/trac/hevc
Accounts are still valid on all sites.
Registered users need to confirm their email address and the account needs to be manually verified by one of the AhG chairs. Please use your real name and an email addresses that helps to identify as a person. Notify the AhG chairs via email in case your account is not verified within 2-3 work days.
A 'captcha' code needs to be entered for registration.
Specific IP addressed are automatically blocked based on suspicious activity. Please notify the AhG chairs via email in case of accidental blocking.
Recommendations of the AHG were to:
Continue to develop reference software based on HM version 16.3 and improve its quality.
Test reference software more extensively outside of common test conditions
Add more conformance checks to the decoder to more easily identify non-conforming bitstreams, especially for profile and level constraints.
Encourage people who are implementing HEVC based products to report all (potential) bugs that they are finding in that process.
Encourage people to submit bitstreams that trigger bugs in the HM. Such bitstreams may also be useful for the conformance specification.

The ftp site at ITU-T is used to exchange bitstreams. The ftp site for downloading bitstreams is
http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/
The spreadsheet to summarize the status of bitstream exchange, conformance bitstream generation is available at this directory. It includes the list of bitstreams, codec features and settings, and status of verification.
The guidelines to generate the conformance bitstreams is summarized in JCTVC-O1010.
For HEVC version 1, JCTVC-S1004 (output document from Strasbourg meeting) summarizes the defects of the current conformance bitstreams. After the Strasbourg meeting, the following problems were revised. All known problems were resolved. The revised bitstreams were uploaded at the following site, separating the bitstreams under ballot.
http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/under_test/
general_profile_idc has reserved value 0 (7.4.4). The value of the general_profile_idc was set to 0 in the revised bitstreams. The value of this flag must be 1. The problems were fixed and the following revised bitstreams were uploaded (AMP_A_Samsung_7, AMP_B_Samsung_7, AMVP_C_Samsung_7, STRUCT_A_Samsung_7, STRUCT_B_Samsung_7).
The spec requires that once decoding end_of_slice_segment_flag with value 1, the remaining bytes in the slice segment data must not be different from zero. (#1283)
The problem was fixed and the following bitstream was uploaded.
DBLK_A_MAIN10_VIXS_4
In the following bitstreams, the value of general_profile_compatibility_flag[0] is not equal to 0. The problem was fixed and the following bitstream was uploaded.
SLIST_A_Sony_5
SLIST_B_Sony_9
SLIST_C_Sony_4
The following new bitstreams to test SAO/Deblocking corner case were provided.
SAODBLK_A_Divx_1
SAODBLK_B_Divx_1
These streams have extreme conditions for SAO and deblocking for CTU size 8x8 that are difficult for multi-threading. The clips are 500 frames long to cause multi-threading problems, use freely available content.
HEVC v.1 conformance test was finalized in Sapporo and it was also agreed to add new conformance bitstream for HEVC v.1 during Sapporo meeting. One bitstream to test SAO corner case was agreed to add during Sapporo meeting and it is inlcuded in the defect report of HEVC v.1 conformance.
It was agreed that we should add additional new bitstreams for existing profiles as feasible.
The bitstreams that had been planned to be generated were reviewed, for version 1, RExt, and SHVC.
Bit depth & chroma format to cover in RExt conformance are as follows.
4:0:0, 4:2:0, 4:2:2, 4:4:4
8, 10, 12, 16b
The initial SHVC conformance plan is available in JCTVC-S1008, including instructions for generation of bitstreams. An editors revision of the draft SHVC conformance plan is available in JCTVC-T0215.
The list of the 44 bitstream categories and their status are available in section 2.6.1.
Volunteers were identified for the bitstreams in 41 categories. 3 categories do not have identified volunteers and additional volunteers are requested. The following 11 companies have volunteered to participate in generation of SHVC conformance bitstreams: Ericsson, ETRI, InterDigital, Fraunhofer HHI, Nokia, Qualcomm, Samsung, Sharp, Sony, Technicolor, and Vidyo.
At the start of the meeting 28 bitstreams in 15 categories had made been available, with 26 categories not yet available. The available bitstreams are based on an SHM-dev branch of the SHM software, because of the current unavailability of an SHM release which conforms to the specification. It is hoped that when a new SHM release becomes available that the available bitstreams will conform and will not need regeneration.
The AHG recommended the following:
to approve the corrections of HEVC v.1 conformance bitstreams
to discuss how new bitstreams for HEVC v.1 be added
to collect missing bitstreams
to promote RExt and SHVC conformance to PDAM at Geneva meeting
Some problems with ftp upload were mentioned.
Proceeding to PDAM for RExt and SHVC conformance testing was requested and agreed.

This report summarizes the Verification test preparation Ad-Hoc Group (AHG5) activities between the 19th JCT-VC meeting in Strasbourg, France (October 2014) and the 20th JCT-VC meeting in Geneva, CH (February 2015).
The ChromaConvert utility was created to perform chroma downsampling and upsampling for the preparation of interlace test sequences.
This utility is included as a build target in the HDRTools software, prepared by A. Tourapis. Please contact the AHG chairs for access to this software.
Access to test material for interlaced video content was negotiated with CBS and NBC Universal. CBS and NBC Universal are thanked for providing test material on terms suitable for verification testing.
The Draft verification test plan for interlaced video and format range extensions (JCTVC-S1003) was produced and uploaded.
Config and per-sequence config files are included.
Scripts/Makefiles for converting yuv10 and sgi input for interlace verification are included.
A patch against HM-16.2 is included that adds support for second-field QP biasing.
Bitstreams production for the verification testing is started:
Qp refinement for bit-rate targeting for the range extensions bitstreams was performed. One additional round is needed (some bit-rates vary much more than expected when QP is adjusted).
Some interlace bitstreams had unexpected bit-rates, further investigation needed (plan to resolve during meeting, with assistance from G. Barroux).
The AHG recommended to:
Finalize bitstreams at target bit-rates.
Select a subset of bitstreams for subjective tests.
Conduct the subjective test.

This report summarizes the activities of the JCT-VC ad hoc group on SCC coding performance analysis (AHG6) between the JCT-VC 19th meeting in Strasbourg, France, and the 20th meeting in Geneva, Switzerland.
A kick-off message for AHG 6 was sent out on Oct. 27.
The following changes have been made in JCTVC-S1015 Common conditions for screen content coding tests:
Added 4:2:0 format and Class F sequences in the text
Provided two separate results reporting templates (Lossy and Lossless) for 4:2:0 sequences.
Changed sign for lossless reporting
Changed categorization in the summary sheet of the reporting templates for 4:4:4 sequences. The new categories are shown below:
RGB, text & graphics with motion, 1080p & 720p
RGB, mixed content, 1440p & 1080p
RGB, Animation, 720p
RGB, camera captured, 1080p
YUV, text & graphics with motion, 1080p & 720p
YUV, mixed content, 1440p & 1080p
YUV, Animation, 720p
YUV, camera captured, 1080p
There were concerns about the quality and quantity of the current 4:2:0 sequences in the common test condition. Suggestions and interests have been expressed to use chroma-subsampled 4:4:4 screen content sequences in future tests.
JCTVC-T0080 presents simulation results that showed turning off ACT for YUV sequences could significantly speed up runtime for simulations, with relatively small impact on coding performance. The authors of that document suggest modifying the common test conditions to turn off ACT at the sequence level. The performance impact of ACT is smaller than what was previously reported, which was said to be due to encoder optimization differences.
JCTVC-T0194 presents statisticical information on the usage of IBC, palette, and intra prediction. Specifically, the percentage of pixels as well as the corresponding bits coded with the IBC, palette, and intra prediction mode, are shown respectively. The authors of that document note that:
The percentage of the video that is coded in IBC is large with full-frame search. The remaining amount of content may not be sufficient for optimization of non-IBC tools.
Chinese text has quite different characteristics from existing test sequences. It may be useful to test non-IBC tools.
The statistics differ substantially depending on the search range of IBC. In particular, palette mode is used much more when the IBC search range is reduced.
It was remarked that a similar phenomenon applies to the use of tiles and slices which also has the effect of reducing search range.
The authors of that document suggested modifying the test conditions and include a constrained search range for IBC, in addition to full frame, in the evaluation of non-IBC tools. They also suggest adding new test sequences with non-alphabetic texts, such as Chinese. See notes for T0052.
JCTVC-T0053, JCTVC-T0062, JCTVC-T0072, JCTVC-T0109, JCTVC-T0120 present methods to enable palette mode for non-4:4:4 formats.
The AHG recommended to:
Study the proposed changes to the common test condition in T0080 and T0194, and create CEs or an AHG if needed to further study these proposals.
Discuss addition of new test sequences. We only have 4 "Class F" (4:2:0 exclusively screen content), and 2 "mixed text & graphics". It was agreed to add another 7 sequences of "text and graphics" (1080p and 720p), bringing the total number of 4:2:0 screen content sequences to 13. See the notes on the BoG report T0229.
Continue to evaluate the coding performance of the newly adopted tools and their interaction with the existing HEVC tools in the Main profile and range extensions.

This document reports on the work of the JCT-VC ad hoc group on SCC extensions text editing (AHG7) between the 19th JCT-VC meeting in Strasbourg, FR (October 2014) and the 20th JCT-VC meeting in Geneva, Switzerland (February 2015).
The second working draft for the High Efficiency Video Coding Screen Content Coding (HEVC SCC) extension was created as an output document following the decisions taken at the 19th JCT-VC meeting in Strasbourg, FR (October 2015).
JCTVC-S1005 was published by the editing ad hoc group (AHG) following the 19th JCT-VC meeting in Strasbourg, France. The text of JCTVC-S1005 has been submitted to ISO/IEC JTC1/SC29.
List of changes with respect to JCTVC-R1005_v3:
Integrated adaptive motion vector precision (JCTVC-S0085)
Moved residual_adaptive_colour_transform_enabled_flag to PPS and refined ACT condition (JCTVC-S0086)
Integrated QP clipping for ACT (JCTVC-S0086, JCTVC-S0140, JCTVC-S0144)
Integrated ACT unification (JCTVC-S0254)
Integrated ACT for different colour component bit-depth (JCTVC-S0180)
Integrated sequence-level disabling of intra boundary filtering (JCTVC-S0102)
Integrated constrained reference area for intra block copying (JCTVC-S0088)
Integrated maximum palette and palette predictor size size signalling in SPS (JCTVC-S0025)
Integrated deblocking for palette mode (JCTVC-S0096)
Integrated syntax optimization for palette sizes 0 and1 (JCTVC-S0099, JCTVC-S0105, JCTVC-S0110, JCTVC-S0173)
Integrated conditional signalling of palette_transpose_flag (JCTVC-S0110)
Integrated changes to palette run length coding (JCTVC-S0269)
Integrated run length coding for PalettePredictorEntryReuseFlag (JCTVC-S0153)
Integrated unification of treatment of escape and index samples (JCTVC-S0258)
Integrated delta qp and chroma qp offset signalling for palette mode blocks (JCTVC-S0043)
Integrated initialization process of palette prediction variables. (JCTVC-S0088)
Integrated TU-based ACT, which is of editorial change. (JCTVC-S0179)
The second working draft does not include encoder restrictions related to overflow in cross component prediction (bug tracker ticket number 1321). There was an additional comment after the 19th JCT-VC meeting indicating that the proposed restriction may not be appropriate for high input bit-depths when extended precision is disabled. It was suggested to be beneficial to have a side activity to study this issue during this meeting to discuss the appropriate restriction and return to the discussion later in the meeting. JCTVC-T0132 is related to this issue.
JCTVC-T0031 proposes editorial improvements to address the feedback and comments related to the second working draft.
The screen content coding test model 3 (SCM 3) (document JCTVC-S1014) was released on 5 February 2015. General tutorial description for adaptive motion vector resolution was added. Encoder search descriptions for palette mode and intra block copying were further refined. Description of adaptive colour transform was updated.
The recommendations of the HEVC SCC extension draft text AHG are to:
Approve the documents JCTVC-S1005 and JCTVC-S1014 as JCT-VC outputs
Address the comments and feedback on SCC extensions text specification as appropriate
Compare the HEVC SCC extensions document with the HEVC SCC extensions software and resolve any discrepancies that may exist, in collaboration with the SCC extension software development (AHG8)
Refine the encoder restriction related to the overflow in cross component prediction, possibly through side activity or a BoG.

HM-16.2_SCM-3.0rc1 was tagged on the SVN HHI repository on November 15, 2014 before the release of HM-16.2_SCM-3.0 to allow proponents to cross-check integrations and interactions with other adoptions. This version is same as HM-16.2_SCM-3.0.
The release was announced on the email reflector. The software can be downloaded at https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/HM-16.2+SCM-3.0rc1/
HM-16.2+SCM-2.1 has been tagged on HHI Server on October 29, 2014 and can be downloaded at https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/HM-16.2+SCM-2.1/
The changes over RExt8.0_SCM2.0 were:
Migration of SCM2.0 HM 16.2.
Removals of macros related to SCM 2.0.
Fix for ticket #1344 (Instances of color changed to colour in SCM).
Fix for ticket #1337 (incorrect address calculation in ACT).
The JCT-VC issue tracker at https://hevc.hhi.fraunhofer.de/trac/hevc/ has been updated to allow bug reports to be entered for SCM, currently under milestone HM+SCC-4.0, version SCC-3.0.
The AHG recommended the following:
Continue to develop reference software based on HM16.2_SCM3.0 and improve its quality.
Remove macros introduced in previous versions before starting integration towards SCM-3.0 such as to make the software more readable.
Continue merging with later HM versions.

This document reports the work of the JCT-VC ad hoc group on SHVC text editing (AHG11) between the 19th JCT-VC meeting in Strasbourg, France (1724 Oct. 2014) and the 20th JCT-VC meeting in Geneva, Switzerland (1018 Feb. 2015).
The status of this AHG was discussed verbally prior to upload of the report.
The editorial team worked on the following two items:
Improve the quality of JCTVC-S1007: SHVC Test Model 8 text
Collect and fix the bugs in the second edition of HEVC specification
The JCTVC-S1007 Test Model 8 document mainly contains the general descriptions of the SHVC framework, texture data resampling process, motion field mapping process and colour mapping process. The main change to the previous JCTVC-R1007 (SHM7) is adding the description related to profile, tier and level signalling.
A list of bugs and editorial issues have been found in second edition of the HEVC specification and the fixes have been provided to the editors.
The AHG recommended to:
Use SHVC bug-tracker (https://hevc.hhi.fraunhofer.de/trac/shvc) to report issues related to SHVC Draft and Test Model text.
Compare the SHVC documents with the SHVC software and resolve any discrepancies that may exist, in collaboration with the SHVC Software AHG.

SHM software can be downloaded at https://hevc.hhi.fraunhofer.de/svn/svn_SHVCSoftware/tags/
For migrating to HM16 (RExt) software base, SHM-8.0 was implemented on top of HM-16.2 and the code can be obtained at https://hevc.hhi.fraunhofer.de/svn/svn_SHVCSoftware/branches/SHM-upgrade. It works fine with HEVC base layer, however some work needs to be done for CGS and external base layer configurations, so it was decided by AHG12 to release it as SHM-8.1 after the work will be completed.
SHM-8.1(tentative) against SHM-7.0 under common test conditions
Development plan and recommendations
Continue to develop reference software based on SHM-8.0 and improve its quality.
Finish migration to HM-16.x base which includes RExt
Resolve identified software and working draft mismatches.
The following were discussed in the review:
Discontinue releasing further versions based on HM15.
SHM8.0 was released based on HM 16.2 (without RExt)
Work on SHM 8.1 was ongoing, and would be based on HM 16.3 (with RExt); currently, CGS and external base layer is not working yet in that context.

HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9873" JCTVC-T0104 HM reference encoder study [C. Fogg (MovieLabs)] [late]
(Consideration of this topic was chaired by GJS on Sunday 02-15 a.m.)
This information document explores a non-normative approach to improving utilization of code levels and resulting coding efficiency, unlike the normative system changes (albeit no decoder reconstruction changes) to techniques such as the code level redistribution or luminance scaling described in JCTVC-T0102. One of the key asserted benefits of the methods in JCTVC-T0102 is to, in effect, assign fewer code levels to dark, usually noise-ridden areas of the transfer function, thus reducing the entropy of the final integer signal in the container conversion steps that take video signal from linear light to the non-linear (perceptually uniform) quantized/integer signal which is passed through a codec chain. A non-normative container or system solution would be to reduce the entropy while retaining detail as much as possible. No changes are required to either the signal container (relationship between integer sample code levels and display intensity) or decoder semantics. A motion-compensated noise reduction algorithm from isovideo is utilized in this study.
(This information contribution was presented and discussed before being uploaded.)
This is a study of non-normative encoding techniques for improving HDR performance. It looks at noise reduction techniques applied to some HDR video, as a way to improve coding efficiency. When measured relative to the denoised input, substantial improvement of coding efficiency was reported.

HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9811" JCTVC-T0042 Comparison of Compression Performance of HEVC Test Model 16.2 and HEVC Screen Content Coding Extensions Test Model 3 with AVC High 4:4:4 Predictive profile [B. Li, J. Xu, G. Sullivan (Microsoft)]
(Consideration of this topic was chaired by J. Boyce on Friday 02-13 p.m.)
This contribution is a study of the relative objective (i.e. PSNR-based) compression performance of HEVC RExt Main 4:4:4 12 Test Model 8 (using 8, 10, and 12 bit configurations), HEVC SCC Test Model 1 (SCM 2) and AVC High 4:4:4 Predictive Profile. It builds upon the prior work reported in JCTVC-G399, JCTVC-H0360, JCTVC-I0409, JCTVC-J0236, JCTVC-K0279, JCTVC-L0322, JCTVC-M0329, JCTVC-O0184, JCTVC-P0213, JCTVC-R0101, and JCTVC-S0084 updating the results by using the latest available reference software (JM-18.6, HM-16.2, HM-16.2+SCM-3.0), profile and test model designs, and the RExt and SCC test sequences. The overall results indicate that for RExt CTC sequences, RExt Main 4:4:4 12 Profile saves 25%, 33%, and 38% bit rate for AI-MT, RA-MT and LB-MT, respectively, relative to AVC High 4:4:4 Predictive Profile. The overall results also indicate that for screen content sequences, the HEVC SCC Test Model 3 also improves quite substantially over JM-18.6. For example, for RGB text and graphics with motion (TGM) 1080p&720 sequences, the HEVC SCC Test Model 3 saves 86%, 80%, and 77% bits for AI, RA and LB lossy coding over JM-18.6.
It was commented that the performance of the SCC coding tools is highly sequence and class dependent, and suggested to consider modifying the SCC test set.
A BoG (H. Yu) was asked to consider recommendations of modifications of the SCC test set. See notes for T0229.
HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9849" JCTVC-T0080 AHG6: Coding performance of SCC tools and suggested common test conditions [P. Lai, S. Liu, S. Lei (MediaTek)]
(Consideration of this topic was chaired by GJS on Friday 02-13 p.m.)
Under common test conditions, this contribution presents coding performance measurements of Intra block copy (IBC), palette, and adaptive colour transform (ACT).
From these measurements, it is asserted that turning off ACT for YUV sequences significantly speeds up runtime for simulations, with relatively minor impact on coding performance. It is suggested to modify the common test condition such that ACT is turned off for YUV sequences at sequence level.
In the discussion, it was pointed out that there was a loss on some individual sequences (one sequence with 6% loss and another with 1% loss for LDB).
It was remarked that the 8% reported speedup is only in the YUV category.
It was remarked that our CTC should be as uniform as possible, unless there's a good reason not to do that. No action on CTC.

(Consideration of this topic was chaired by GJS on Friday 02-13 p.m.)
This contribution presents statistical information on the usage of IBC, palette, and intra prediction. Specifically, the percentage of pixels is shown as well as the corresponding bits coded with the IBC, palette, and intra prediction mode, respectively. With reference to these data, it was proposed to further modify the test conditions and include a constrained search range for IBC, in addition to full frame, in the evaluation of non-IBC tools. The contributor also suggested consideration of adding new test sequences with non-alphabetic texts, such as Chinese.
A BoG was asked to consider the test sequence selection.
See notes for T0006, T0052 and T0229.

Per the notes on T0006 and T0229, it was agreed to modify the selection of the test sequences to be tested for SCC CTC.
Core experiments in SCC (52)
CE1: Palette mode improvement (12)
CE1 summary and general discussion (1)
(Consideration of this topic was chaired by GJS on Tuesday 02-10 p.m.)
HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9970" JCTVC-T0021 CE1: Summary report of CE on improvements of palette mode [P. Lai, P. Onno, R. Cohen, V. Seregin, X. Xiu, Z. Ma (CE Coordinators)]
This document summarizes the Core Experiment 1 (CE1) on improvements of palette mode.
In the 19th JCT-VC meeting in Strasbourg, Core Experiment 1 (CE1) was formed with five tests, to further investigate improvements of the existing palette mode in SCM-3.0. This contribution describes test conditions, test results, and comparisons.
Category A Generalized copy above mode for palette Index coding
Test A.1 Extended copy above mode to the first line
Proponent: MediaTek, JCTVC-S0079/S0114; Qualcomm, JCTVC-S0155
MediaTek and Qualcomm, JCTVC-T0036/T0037
Crosschecker: Fujitsu, JCTVC-T0151
This test evaluates enabling COPY_ABOVE_MODE for coding palette indices in the first line of a palette-mode CU. The indices of the neighbouring CU pixels are used as reference indices for the COPY_ABOVE_MODE, and the indices are derived with the palette of the current CU. Simplifications for the index conversion (from pixel to index) are tested.
Index conversion with search over all palette colours
A.1.1 with SCM3.0 palette index redundancy removal on all indices coded.
A.1.2 with SCM3.0 palette index redundancy removal on applicable indices.
Index conversion with reduced number of colours that are searched (from 32 to 8)
A.1.3 with SCM3.0 palette index redundancy removal on all indices coded.
A.1.4 with SCM3.0 palette index redundancy removal on applicable indices.
A.1.5: Directly copy the pixel values, instead of converting the pixel values into palette indices.
Index conversion with search using only the primary colour component, with or without reduced number of search
A.1.6 with SCM3.0 palette index redundancy removal on all indices coded.
A.1.7 with SCM3.0 palette index redundancy removal on applicable indices.
A.1.8: Infer neighbouring CU pixels indices as 0 (similar to JCTVC-S0155).
A.1.1 Full redundancy removal, Index conversion loop over entire palette, with 3 components
A.1.2 Partial redundancy removal, Index conversion loop over entire palette, with 3 components
A.1.3 Full redundancy removal, Index conversion loop over 8 palette entries, with 3 components
A.1.4 Partial redundancy removal, Index conversion loop over 8 palette entries, with 3 components
A.1.5 Partial redundancy removal, directly copy pixel values
A.1.6 Full redundancy removal, Index conversion loop over entire palette, with 1 component
A.1.7 Partial redundancy removal, Index conversion loop over entire palette, with 1 component
A.1.8 Infer neighbouring CU pixels indices as 0
Summary: 7 methods (A.1.1-A.1.7) have roughly similar compression performance benefit relative to the current design. The 8th (A.1.8) is not interesting. A.1.5 (called "copy pixel") is the least complicated.
In A.1.5, when the above pixel is escape coded and within the current CU, the current pixel is treated as escape coded not as a copied value. A non-CE proposal suggests to instead copy the value rather than the escape indication in this case.
The suggested conclusion was that A.1.5 is better than the current design and better than the other A.1.x proposals. It was suggested that T0054 is related. However, that proposal is not yet well-studied, and results were not provided on time, and it was suggested that the gain shown in T0054 seems to be less than that of A.1.5.
It was initially agreed to adopt A.1.5. However, later in the meeting, a problem with this plan was noted, and a different approach was adopted. See the notes for T0231.
Test A.2 Generalized copy above mode
With the extended copy mode techniques described in Test A.1, this test evaluates a generalized copy above mode, where the converted indices or pixel values can be copied. The proposed generalized copy above mode is signalled by a copy above mode flag, followed by an offset which specifies the distance between the row being copied from and the current row being coded. Constraints on the maximum offset for each row were also tested, and results for the mode constrained within the CU are provided as well.
Method 1: Copy from multiple rows above, when copy from outside CU: Full redundancy removal, index conversion loop over entire palette, 3 components.
Method 2.1: Copy from multiple rows above, when copy from outside CU: Partial redundancy removal, index conversion loop over entire palette, 3 components.
Method 2.2: Copy from multiple rows above, when copy from outside CU: Partial redundancy removal, index conversion loop over 8 palette entries, 3 components.
Method 3: Copy from multiple rows above, when copy from outside CU: Partial redundancy removal, directly copy pixel values
Method 4: Copy from multiple rows above, when copy from outside CU: Infer as index 0.
Method 5: Copy from multiple rows above, cannot copy from outside CU.
After the conclusion of the A.1.x category, it seemed that only method 3 in the A.2 category needed to be considered. The benefit for text & graphics and mixed content for this seems to be about 0.4%. An extra syntax element is sent to indicate how many rows above to reach up to get the value to copy. Two rows outside the current CU are needed, and all rows within the current CU. Additional encoder searching (and syntax sending) is needed. The 0.4% gain did not seem worth the complication added by the multi-line referencing. No action was therefore taken on this.
(The measured runtime differences are not necessarily reliable.)
Category B Colour index coding
Test B.1 Modified palette run coding
Proponent: Qualcomm, JCTVC-S0111, JCTVC-T0034
Crosschecker: ITRI, JCTVC-T0180
Description:
This test evaluates a modification of the binarization for run coding. A shorter codeword is assigned to the run to the end of the block. Two methods are tested. In one method, a symbol (such as 3) is reserved for the run to the end of the block. The reserve value may be varied depending on the maximum possible run. Different reserve values are tested. In the second method, sending an additional flag to indicate the run to the end of the block is tested. Context coding of the flag is tested. Related redundancy removals such as conditional signalling, CU level enabling flag, are also be tested in combination with the proposed methods. The results shown below are for the second method (using a flag).
There may be a reduction in the average number of parsed bins using this method, but this was not checked.
There are some non-CE contributions that are related, and have larger gain.
No action was on this CE proposal.
SHAPE \* MERGEFORMAT
Category C 2-D index map coding of palette mode
Test C.1 2-D index map coding of palette mode
Proponent: Huawei, JCTVC-S0151, JCTVC-T0124
Crosschecker: Qualcomm, JCTVC-T0032
This test evaluates 2-D index map coding methods designed for improving the performance of the palette mode. The proposed method is available as an additional method for coding palette indices. A flag associated with each run indicates which method to use (1-D or 2-D). The 1-D method is a modified version of the current method for coding palette indices. If 2D_flag = 1, COPY_ABOVE flag is skipped, otherwise, COPY_ABOVE flag is coded using only one context (2 contexts are used in the default RUN-based 1-D search).
References outside the CU are converted to indexes using a mapping process.
The anchor was not the CTC.
The technique is similar to IBC, but has a more flexible shape and positioning and uses index mapping rather than direct value referencing. A related non-CE proposal T0192 uses direct value referencing, to avoid the index maping process.
In the 1x4 case, the rows above the current CTU are not referenced only the CTUs to the left.
No action was taken on the CE scheme as-is.
Test 1: IBC 1×4 CTU, 2D index map coding 1×4 CTU (anchor: IBC 1×4 CTU)
Test 2: IBC 2×4 CTU, 2D index map coding 2×4 CTU (anchor: IBC 1×4 CTU)
Test 3: IBC 3×5 CTU, 2D index map coding 3×5 CTU (anchor: IBC 1×4 CTU)
Test 4: IBC full-frame as common test conditions, 2D index map coding 1×4 CTU (anchor: IBC 1×4 CTU)
Category D Encoder modification of palette coding for escape pixels
Test D.1 Encoder modification of palette coding for escape pixels
Proponent: ITRI, JCTVC-S0048, JCTVC-T0044
Crosschecker: Qualcomm, JCTVC-T0033
This test evaluates a fast algorithm that adaptively determines the size of major colour table. The algorithm may change a number of major colour pixels to escape pixels or change a number of escape pixels to major colour pixels.
This is an encoder-only modification, changing the decision-making process between what is coded as a palette entry versus what is coded as escape mode.
Version 1 (no increase in R-D checks)
Version 2 (one additional R-D check)
Some losses were noted in RA and LB. The proponent indicated that the results can be improved, based on a related non-CE contribution T0169. Another related contribution is T0087.
No action was taken on the CE.

On Harmonization of IBC with inter
Test 1: Intra block copy and Inter signalling unification (JCTVC-T0094)
In JCTVC-S0113 and JCTVC-S0302, the IBC mode is signalled without intra_bc_flag but reusing inter signalling by adding the current picture to the reference picture list(s) instead. With the shared signalling, IBC can be differentiated from the conventional inter mode by checking the selected reference picture.
On PU IBC on/off
Test 2: Intra block copy signalled at PU level (JCTVC-T0071)
In JCTVC-S0121, the result for PU level IBC on/off on top of SCM-2.0 was provided. In this test, the performance of PU level IBC on/off is tested on SCM-3.0.
On IBC merge/skip mode
Test 3.1: IBC merge mode using HEVC merge candidates (JCTVC-T0040)
In JCTVC-S0081, merge candidates for IBC are constructed according to inter mode. In this test, the performance of this method is tested on SCM-3.0.
Test 3.2: IBC merge mode using default candidates (JCTVC-T0073)
In JCTVC-S0123, some default IBC merge candidates are added to the merge list when the merge list is not full. In this test, the performance of this method is tested on SCM-3.0.
On IBC deblocking
Test 4.1: On deblocking for screen content coding (JCTVC-T0039) Note: 4.1 is not a harmonization
In this test, the boundary strength rule is altered as follows:
if either side of an edge is IntraBC, BS = 1,
else, if either side of an edge is Intra, BS = 2,
else, apply inter rules to select between BS = 1 or BS = 0.
Test 4.2: Inter deblocking for IBC (JCTVC-T0095)
In JCTVC-S0112, IBC is treated as inter mode during the deblocking process. Moreover, in order to keep the deblocking module unchanged, after an IBC block is decoded and before the deblocking process, it is converted to be a uni-directionally predictive inter block with the BV being its MV and the current picture being the reference picture.
On Vector coding
Test 5.1: Vector binarization (JCTVC-T0089)
Note: 5.1 also changes the current MVD coding of HEVC. None of the tests has used the current MVD coding method for BVD, as it was asserted this would gve considerable loss
In this test, first a context coded flag is coded to indicate MVD is zero. When MVD is not zero, another flag may be coded to indicate if absolute level of MVD is greater than N. If MVD is greater than N, the remaining absolute level is coded using bypass Exp-Golomb codes. One flag is coded to indicate sign of the vector.
(Test 5.2: IBC BV coding for small PUs withdrawn)
Test 5.3: Block vector coding for IBC (JCTVC-T0090)
In this test following aspects have been tested separately and jointly. a) One flag is added to specify whether the vector is predicted or not. If not predicted, vector is coded without prediction. b) Reducing redundancy of vectors with respect to their sign and absolute values.
The combination of 5.1+5.3 is tested and results are provided.
On BV Prediction
Test 6.1: On BV predictor (JCTVC-T0040)
In JCTVC-S0087, IBC merge mode is simulated using the current BV predictors and BVD=0. In this test, the performance is evaluated in the context of SCM-3.0.
Note: Test 6.1T1 modifies the candidate list construction, whereas 6.1T2 uses the current list construction. Both 6.1 tests are using only 2 candidates in the final list.
Test 6.2: On IBC BV prediction method (JCTVC-T0096)
In JCTVC-S0112, the line buffer for HEVC AMVP is shared with IBC such that the above spatial neighbours can be used for BV predictor as well with no additional buffer requirement.
Combination Tests
Test 7: combination of Test 1 and Test 3.2 (JCTVC-T0075)
In this test, the software in test 1 is used as the platform. Default IBC merge candidates are added to the merge list when the list is not full.
Test 8: combination of Test 1 and Test 5.1, Test 5.3 (JCTVC-T0089, JCTVC-T0090)
The binarization methods described in test 5.1 and test 5.3 are tested under the unification framework of Test 1.

Implicitly, it enables merge/skip, bi-prediction from inter and intra and mixed prediction (sub-CU inter/intra) which explains some of the gain.
It is furthermore pointed out that two macros are turned on that partially contribute to the gain. (0.50.7%). Related to checking the correct decision for mixed prediction, involving 3 components in the vector search.
With regard to de-blocking, when constraint intra prediction flag is on, IBC goes back to intra, which could cause a contradiction. The same would be the case with test 2, which basically treats IBC as inter mode.
Restriction to 4x8 is asserted to lead to loss, which is however compensated by the other benefits.
Several experts expressed opinion that it would be desirable to achieve a true harmonization, where the current inter mode of v1 (including MV coding, binarization etc.) is used as is. It was also expressed that the advantage of such a unification would even outweigh a certain loss in compression.
Continue CE in this regard. In this context, it should also be considered to use an efficient way of coding the integer-pel MV of IBC, e.g. by signalling in quarter-pel and using the adaptive MV resolution flag at slice level. It is expressed during the discussion that a specific modification for IBC just shifting the MV after the decoding would be more acceptable than modifying the binarization or CABAC.
Test 2a/b gives information about sub-PU IBC (with intra/inter DBF). Compared to test 1, it uses 4x4 still. This also unveils that inter deblocking is giving benefit for IBC
Test 3 is showing the benefit of merge; 3.2 fills the list with additional candidates
Test 4 tests de-blocking (where the inter de-blocking 4.3 performs better than the specifically modified version 4.1)
Test 5.1 modifies the vector binarization for both MV and BV coding. It is however not a complete unification, using different context models for MV and BV. For camera-captured content, a small loss is observed in some cases (0.1% in LD)
Test 8 (5.1) uses the same context model and same binarization from 5.1 for BV and MV. It is however still performing a shift of MV as from Test 1.
The common understanding is that
Either a full unification is achieved (in which context an MV shift operation when used for IBC is acceptable, but MV coding different from v1 would not be desirable, and modificaton of AMVP/merge would also not be desirable), or
Design IBC as third mode beyond intra and inter prediction, and then with the usual tradeoff complexity/performance. This should branch off at the CU level (which would not qualify test 2).
With regard to merge (test 3) two concerns are raised a) it may be not well parallelizable due to 4x4 blocks and 5 candidates and b) some of the gain could be achieved by encoder only modification (see 6.1 T2).
It is requested to report results of the unified solution (as described above). If resonable (expectation is that the gain compared to current SCM would still be around 1% for RA and LD) this is likely to be adopted. See further notes under JCTVC-T0227.
Some of the other methods investigated in CE2 also give additional gain compared to SCM, however
Test 2 (sub-CU) would have the disadvantage that it does not cleanly define a third mode at the CU level
Test 3 (4x4 merge) may have some implications wrt parallelization, and some of the gain could also be achieved by encoder-only (test 6.1T2)
Test 4.2 (using inter deblocking for IBC) obviously gives benefit, but would be implicit in the unified solution
Test 5.1 would be undesirable because it changes the MV coding (would need to be modified such that it only changes the BV coding, such that 5.3 would better); 5.3 could be another add-on over current SCM, but only gives 0.5%
Test 6.1T1 uses 5 candidates for BVP, which also raised some complexity concerns
Test 7 would not fit the unification, as it modifies the merge list construction
From the current results, it is not obvious that a separate mode would have significant compression advantage compared to the unified solution.

The intra line copy (ILC) technique divides a PU row-wise or column-wise into lines and performs the intra-copying operation within a given search range (i.e. 1x2 CTUs as in A1, and 1x4 CTUs as in A2 and A3) inside the current frame. Pixels within the current CU cannot be taken as reference. Syntax-wise, a PU-level flag is introduced when intra_bc_flag is enabled to indicate the use of IntraLC mode, and another flag is sent for each ILC PU to indicate the splitting manner.

branches after the IBC flag at the CU level, and the intra line copy is an additional prediction mode replacing IBC when invoked.
Test B: Intra string copy
All contributions in test B are modifications to a CE3 basis software, which goes back to a software used in previous CE10. Signalling is done in a way that branches after the IBC flag at the CU level, and the intra string copy is an additional prediction mode replacing IBC when invoked.

X-check: HYPERLINK "http://phenix.int-evry.fr/jct/doc_end_user/current_document.php?id=9949" JCTVC-T0178
In this test, the notion of ISC is applied to the coding of palette index map. A CU-level flag is introduced to switch adaptively between the proposed Flexible 2D Block Coding (F2D) and the SCM-3.0 palette index coding. Various settings (1x4, 2x4, 3x5, FF) for local search area are tested.
When using F2D, another flag is introduced to switch adaptively between 1D and 2D index coding mode for each string. The 1D mode is the same as COPY_ABOVE mode except that only one context modeller instead of 2 is used to encode COPY_ABOVE mode flag. Strings coded by using the 2D mode can be any rectangular shape, and the indices within each rectangle are coded by using a string-copying technique to fetch reference indices from the reconstructed area in the current frame and therefore re-quantization of reconstructed pixels is required.
The F2D also emulates COPY_LEFT mode by signalling a single pixel colour, zero mvx, and zero mvy. This pixel colour can be explicitly signalled or predicted by using a frequent pixel table (i.e. same as the palette major colour table).
Besides, the same residual coding as SCM-3.0 is required when a CU is coded by using F2D.
Vertical palette index scanning is disabled in this test.
Note: Test B1.2 (and B3 which is also based on it) uses a modified palette mode for prediction, followed by residual coding. If implemented as tested here, it means that first the palette syntax and operations need to be passed and afterwards, residual coding is invoked (whereas current palette from SCM completely bypasses PU and RQT). This is the reason why CABAC throughput is going beyond the current worst case.
Test B2: Pseudo 2D (P2D) Matching Mode
Proposal: HYPERLINK "http://phenix.int-evry.fr/jct/doc_end_user/current_document.php?id=9904" JCTVC-T0135
X-check: ???
In P2D mode, the current string and its reference string have exactly the same 2D shape. A pair of offsets, x and y, are used to indicate the position of the reference string inside the current frame. The syntax parsing for offset x depends on the value of offset y.
A special case of the P2D mode occurs for single-colour strings. In this case, P2D signals the colour of such strings instead of their offset x and y. This colour can be explicitly signalled or predicted by using a secondary reference buffer (e.g. similar idea to the palette colour prediction). This mode is very similar to the COPY_LEFT mode except that the copying operation is applied in pixel domain but not in palette index domain.
Vertical scanning is enabled in this test.
Test B3: Pixel Based Flexible 2D Block Coding (F2D)

This test is performed based on Test B1.2 with enabling vertical scanning for palette index map coding. Furthermore, outside the current CU no single pixel are accessed, the smallest string can be a 4x4 block.
Test B4.1: Memory Bandwidth Reduction I

This proposal introduces a constraint on the string length of ISC (compared to the basis software) to reduce worst-case memory access bandwidth. The minimum string length applied is of 4 pixels.
Test B4.2: Memory Bandwidth Reduction II
Proposal: HYPERLINK "http://phenix.int-evry.fr/jct/doc_end_user/current_document.php?id=9905" JCTVC-T0136
X-check: HYPERLINK "http://phenix.int-evry.fr/jct/doc_end_user/current_document.php?id=9950" JCTVC-T0179
This test is performed on top of Test B2 (Pseudo 2D Matching Mode). It additionally introduces a constraint on the string length of ISC to reduce worst-case memory access bandwidth. The minimum string length applied is of 20 pixels, but such constraint is applied only when part of the reference pixels of a string overlap with the reconstructed pixels lying outside of 2-CTU search range.
Syntax design and matching criterion used in this test are different from Test B4.1.
Vertical scanning is enabled in this test.

The 1-D matching dictionary mode is tested on top of the 2D matching dictionary mode. Only the pixels that are coded by using the 1-D matching mode are stored in the dictionary (unless the number of stored pixels exceeds the pre-defined dictionary size) and can serve as reference pixels for prediction.

Notes from the discussion:
Generally, for lossy coding, test A proposal (intra line copy) performs better than any of the category B proposals
For lossless coding, test B proposals perform better. In this case, likely more short strings are accessed, which partially explaining the significant increases in runtime.
The reports on memory bandwidth for 4.2 may not be fully valid, as it assumes that a 2 CTU cache is available. Therefore, at least for test condition 1, the same would apply for all 1x1 size proposals.
Proposals that make some restriction in memory bandwidth are test A (line copy 1x4) and test B4.1 (4x1 string copy). Furthermore, for test B3 the value for memory access should be rather in the same range as 4x4 IBC, since pixel copy is restricted to current CU. However, B3 (as currently implemented) has considerable increase in worst case context coded bins. It is reported by proponents that at least in the lossy case this could be avoided by disabling residual coding (no results on this available).
Generally, due to the concept that intra line is extending IBC, the version tested in the CE has become obsolete due to the unification of IBC and inter coding (see notes for T0227).
B1.2 and B3 were not tested under test condition 1.
Gain that is reported from test A lossy is in the range of 2-3% for AI, 1-2% for LD/RA (for CTC, those gains are rather at the lower end of those numbers), for the TGM classes. Technologies from test B provide slghtly less gain for the lossy case. Some of the test B methods have even losses in the non-screen content classes.
For test A, some performance gain is also observed for mixed content (but lower than TGM)
For lossless coding, test B7 shows around 6% BR reduction for AI, 3% for RA, 2% for LD under CTC, and 9/5/3% under test condition 2 (restricted search range) (only for SC classes, not for camera captured content). Other test B proposals show less gain, but some of them still more than test A which gives 2/1.3/1 for AI/RA/LD in CTC.
Note: Due to the new method of computing BD gains for the TGM (averaging 1080 and 720 in one class), it is not visible from these numbers that the gain in 1080 is higher.
In case of lossy coding, intra line copy (test A) is giving the best performance gain (see above). It is however increasing the complexity by enforcing a kind of sub-PU partitioning.
The number of context coded bins for the vectors is increased, but in the method of test A RDPCM is diabled which keeps the worst case number of context coded bins below the current limit.
Intra line copy adds complexity at several parts of the processing chain: Increasing the number of block vectors to be coded, processing and memory access at sub-PU level, change of residual coding (disabling RDPCM).
In case that IBC would be harmonized with inter coding (as per CE2), the additional definition of such a prediction mode would not be justified by the compression gain that is reported.
If IBC stays as a third mode, ILC could be regarded as a sub.mode of it. Also for this case, there is no doubt that the complexity is increased compared to IBC, mainly due to the need of performing sub-PU partitioning and line-wise access in the prediction, and quadrupling the number of vectors. Implications to off-chip memory bandwidth (in case where no sufficient cache is available) have not yet been sufficiently investigated. Basically, the situation has not changed relative to the last meeting, i.e. that memory bandwidth with need for off-chip access (if no sufficient cache size would be available) is unacceptable.
Another aspect that is discussed is the possible restriction of IBC access range, which may be necessary would cause some compression loss, and might make the unification with motion comp less attractive from the implementation perspective. If such a restriction would be made, the gain reported by ILC might at least partially compensate for the loss caused by an IBC restriction.
For test B, interesting compression gain is reported for the case of lossless coding. In this case, no residual coding is applied, such that intra string copy would be operated as an alternative against palette or conventional (prediction/residual) coding branching from the CU level. However, the proposal that provides most gain (B7) would require 3 MByte additional on-chip memory at the decoder, and 20 MByte at the encoder for the dictionary, which is unacceptable implementation-wise. Some of the other proposals have potential problems in CABAC throughput, or memory bandwidth as per the tables above (which may be resolved in some of the CE related contributions).
Conclusion:
Intra line copy: Discontinue investigations due to the fact that IBC/inter have been harmonized and it would no longer fit into such a framework
Intra string copy: See notes in section REF _Ref400627477 \r \h 5.1.3; further study was encouraged, provided that sufficient benefit can be shown. No official study was established as a CE from this meeting.

HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9817" JCTVC-T0048 Non-CE1: On palette prediction for slices [C. Gisquet, T. Poirier, G. Laroche, P. Onno (Canon)]
(Consideration of this topic was chaired by GJS on Tuesday 02-10 p.m.)
The present contribution first reports issues found in the SCM3.0 encoder when various encoding features such as tiles and slices are enabled. It is asserted that when those features are enabled, the palette prediction is interrupted or reset and this leads to a significant loss of the coding efficiency. This contribution thus proposes a modification of the palette prediction mechanism to overcome this issue, where a PPS-level table is used to initialize the palette predictor. It is reported that the proposed normative change provides a BDR gain of 1.7% to 2.7% over SCM3.0 (when using slices of 1500 bytes maximum) for the screen content classes, using the All-Intra scenario.
Part of this relates to IBC rather than palette. See notes in section on T0056 for that.
Coding efficiency effects of slice & tile resets were discussed. In the current design, the palette is reset.
The contribution proposes to initialize the palette predictor with PPS-level entry values.
Loss resilience was also suggested as a justification for having a high-level initialization.
Test results for 1500 bytes/slice were reported.
A suggestion was to use only previous frames not including the current frame for constructing the global predictor, for delay reduction. Analysis was done for a current frame and sent in the PPS, then reused for other frames (to save syntax bits).
The coding of the values in the global palette used FLCs.
It was mentioned that there was some prior discussion of palette initialization.
(Further consideration of this topic was chaired by GJS on Sunday 02-15 a.m.)
Side work on a low-delay version of this was conducted (and was reportedly partly cross checked by Nokia). Even when the initialization was based on the previous frame, the technique was shown to have almost the same effectiveness.
The anchor was modified to fix problems with slice constraints (see also notes for T0055 and T0056).
It was remarked that the proposed syntax has a PPS dependency on the SPS.
A modified syntax was presented. Aside from minor editorial issues such as syntax element names and the use of word phrases instead of precise variable or syntax element expressions, it was noted that it should account for the number of actual colour components (either by using some syntax element sent earlier in the PPS if available, or by adding one if necessary).
Decision: Adopted (the PPS-level initialization, revised as noted).

HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9821" JCTVC-T0052 Non-CE1: Escape coded pixel prediction for palette based coding [J. Ye, J. Zhu (Fujitsu)]
(Consideration of this topic was chaired by GJS on Tuesday 02-10 p.m.)
In this contribution, escape coded pixels are proposed to be predicted by palette predictor or escape predictor which is constructed by the escaped pixels occurred in previous palette-coded CUs. There is a CU-level flag to indicate existence of escape coded pixel prediction mode in current CU. If the prediction exists, for each escape pixel, a flag is used to indicate current escape coded pixel is predicted or not. For those escape coded pixels which are predicted, use an index to indicate which element of predictor is its prediction.
Three schemes were tested. 1) Escape coded pixels are predicted by palette predictor. Reported test results show gain of 0.1% and 0.2% on TGM RGB and YUV (AI-lossless) on top of SCM3.0 anchor when maximum palette predictor size is 64; 2) Escape coded pixels are predicted by escape predictor. Reported test results show gain of 1.0% and 1.4% on TGM RGB and YUV (AI-lossless) on top of SCM3.0 anchor when maximum escape predictor size is 64 and gain of 1.5% and 2.0% on TGM RGB and YUV (AI-lossless) on top of SCM3.0 anchor when maximum escape predictor size is 128; 3) Escape coded pixels are predicted by palette predictor and escape predictor. Reported test results show gain of 1.5% and 2.0% on TGM RGB and YUV (AI-lossless) on top of SCM3.0 anchor when maximum palette predictor size is 64 and maximum escape predictor size is 64.
This is a follow-up on S0052, S0053, S0054 by the same proponent.
Three methods were considered for predicting escape coded values.
It was remarked that some aspects of this seem similar in spirit to simply increasing the palette size, which generally helps for lossless coding. The amount of storage is increased.
A comparison to simply increasing the palette size and/or palette predictor size would be needed to determine whether the scheme is beneficial relative to that for the same amount of memory increase. It was remarked that the gain seen for larger memory capacity at the last meeting was roughly similar.
For lossy coding, there is basically no benefit.
No action was therefore taken on that on the proposed normative change.
The contributor advocated that our SCC CTC should use smaller QPs now we use 22, 27, 32, 37.
(Further consideration of this topic was chaired by JRO & GJS Friday 02-13 a.m. and later chaired by GJS Friday 02-13 p.m.)
In initial discussions, it was tentatively agreed to shift down the testing range to 17, 22, 27, 32. This would allow us to construct two curve ranges easily, although it was suggested that the summary report should report the lower QP range results. Further discussion of this was requested.
It was suggested to make sure we don't cross over into lossless territory or get too close to lossless. It was later commented that this seems not to be a big concern.
Doubling the palette size and palette predictor size was suggested if we lower the QP values. Further discussion was suggested after checking on how much difference that seems to make.
It was commented that there is some memory inefficiency in the HM.
The IBC referencing range was also discussed. The suggestion was to run both 4x1 (2x1 local search) and full frame IBC variants in CTC.
(Further consideration of this topic was chaired by JRO & GJS Saturday 02-14 p.m.)
Decision: 1) Don't change the QP points, 2) Double the palette and palette predictor size anyway, 3) Test both IBC search ranges for lossy 4:4:4 cases.
Remark: Why aren't we testing low-delay P instead of or in addition to low-delay B? This issue was postponed for further study.

(Consideration of this topic was chaired by GJS on Tuesday 02-10 p.m.)
Proposes to use pixel value directly, rather than index, for copy-above mode.
In this contribution document, it is proposed to use pixel value instead of index for copy above mode in palette mode. And copy above mode is applied for the 1st line of CU. Reported test results show gain of 0.3% and 0.4% on AI-lossless of TGM RGB and YUV and 0.7% and 0.8% on AI-lossy TGM RGB and YUV contents on top of SCM3.0.
Less gain seems reported than for A.1.5. No action was taken on this.

(Consideration of this topic was chaired by GJS on Tuesday 02-10 p.m.)
In HEVC and its non-SCC extensions, hardware decoding is often pipelined with 32x32 processing units due to the maximum transform block size equal to 32x32. In SCM-3.0, a 64x64 traverse scan is utilized for 64x64 palette coded block. A different block pipelining scheme (e.g., 64x64, which results in significantly larger silicon area) is needed. In this contribution, the 64x64 traverse scan is divided into four 32x32 traverse scans to accommodate to the 32x32 block pipelining. It is asserted that the implementation cost can be reduced. It is reported the BD-rate increases are 0.00.2% with average smaller than 0.1%.
Bit rate loss for simply disabling 64x64 is reportedly around 0.3%.
It was suggested that both this and the 32x32 max size restriction be retested in conjunction with the A.1.5 adoption.
Retesting of A.1.5 versus this versus 32x32 max size restriction was requested.
(Further consideration of this topic was chaired by JRO & GJS Friday 02-13 a.m.)
Testing with A.1.5, 64x64 with 32x32 subscan reportedly has 0.00.1% coding efficiency impact, versus 0.20.4% for just disallowing 64x64 palette mode. It was commented that encoders could use multi-block optimized palette design or other techniques to avoid the penalty from disallowing 64x64 palette mode.
It was discussed how we would express the disallowing of 64x64 size.
The 32x32 restriction was noted to correspond with the maximum transform block size in HEVC.
Decision (cleanup): Disallow palette mode for 64x64 CUs (see "method 2" in proposal).

(Consideration of this topic was chaired by GJS on Wednesday 02-11 a.m.)
In HEVC Screen Content Coding (SCC) Extensions, palette_escape_val is binarized using truncated binary (TB) code with cMax calculated by a procedure that is asserted to be complicated. This contribution proposes to fetch cMax from a predefined table directly with QP as the table input. Experimental results reportedly show that coding performance is not changed by the proposed method.
This is just an editorial change, suggesting to specify the derivation using a table instead of formulas, but not changing the value that is derived. It was commented that it may be better to use formulas in the text, in order to show the principles behind the derived numbers. Delegated to the editors for consideration, but tentatively no action appeared necessary.

(Consideration of this topic was chaired by GJS on Wednesday 02-11 a.m.)
The first reported problem is that the existing escape pixel in SCM3.0 and the spec reportedly has a division problem in calculating the maximum possible quantized value. This contribution presents several proposed solutions to solve this problem.
Solution 1 utilizes a look up table of 6 elements to store six scaling factors (the same as the one used in SCM3.0 encoder) to derive the maximum possible quantized escape pixel value.
Solution 2 utilizes a look up table of 52 elements storing the maximum value for each QP.
Solution 3 utilizes qP and bitDepth to derive the number of bins for fixed length codeword for escape pixels. This changes the reconstruction scheme such that only step sizes that are powers of two are used. (This is somewhat similar in spirit to our IPCM mode, which also can include a shift.)
Solution 4 utilizes a variable-length binarization codeword for quantized escape pixels which is independent on the maximum possible values (i.e., has no explicit upper bound).
The proposed solutions are all implemented based on CE3 common software, and the simulation results reportedly demonstrate that they all have negligible RD difference under CTC.
Comments during the review included:
It was noted that the amount of escape-coded pixels in the CTC is smaller than it would be for very-low-QP operation. Consideration of low-QP and lossless operation seemed needed.
A participant said that "solution 4" seemed the cleanest. It was noted that the test results show some loss of coding efficiency (up to 8% with a 31-entry palette, although using a larger palette seems likely to be beneficial in that case) for that scheme.
As a second reported problem, the existing escape reconstruction has undefined negative right shift operations. It is proposed to be aligned with the current coefficient dequantization to avoid undefined operations. And this has no effect on CTC.
Contribution T0118 has an alternative approach for both reported problems. See notes for T0118.

HYPERLINK "http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=9887" JCTVC-T0118 Non-CE1: On escape colour coding for palette coding mode [X. Xiu, Y. Ye, Y. He (InterDigital)]
(Consideration of this topic was chaired by GJS on Wednesday 02-11 a.m.)
This contribution proposes to change the escape colour coding method for the existing palette design in HEVC screen content coding specification draft 2 and the test model SCM-3.0. Specifically, two defects of the current escape colour coding method are identified. Firstly, the calculation of the maximum value for the truncated binary code of escape colours does not match the actual dynamic range of quantized escape colours. This affects the efficiency of palette coding mode, especially for medium to low QPs, due to the insufficient dynamic range represented by the truncated binary codewords. Secondly, the inverse quantization process of escape colours is not properly defined, causing the right-shifts to become negative for high QPs. Solutions are proposed to resolve the above issues in the existing design, and tested for both low QPs (i.e., 0, 1, 2, 3) and high QPs (i.e., 42, 43, 44, 45) in addition to the QP settings in the common test conditions.
Compared to SCM-3.0 lossy anchor, for low QPs, the proposed methods reportedly provide an average {G/Y, B/Cb, R/Cr} BD-rate savings for AI, RA and LB of {13%, 10%, 10%}, {6.5%, 5.7%, 5.6%} and {2.1%, 2.1%, 2.1%}, respectively, for the sequences in the categories text & graphics with motion, 1080p & 720p in both RGB and YCbCr colour formats. For high QPs, the corresponding reported average {G/Y, B/Cb, R/Cr} BD-rate savings are {0.1%, 0.2%, 0.1%}, {0.2%, 0.2%, 0.1%} and {0.0%, 1.4%, 0.2%} respectively. The proposed methods reportedly do not bring any performance loss for the QP settings in the common test conditions.
The cMax calculation proposed is the same as the the "solution 1" scheme proposed in part 1 of T0112.
The method of handling right shifts is essentially also equivalent to part 2 of T0112, except possibly in some rounding detail.
(Further consideration of this topic was chaired by JRO & GJS Friday 02-13 a.m.)
It was later confirmed that there is exact equivalence of the inverse quantization formula, and the T0118 expression seems editorially preferred. Also the range calculation here is the same as the first such variant proposed in T0112.
Decision: Adopt, but specify that when cu_transquant_bypass_flag is equal to 1, the cMax is (1 @ A B Y Z [ \ x y òéÝÕÍ¿´©¿}s}s`RIRhgi%mHnHuhY$hgi%0JmHnHu$jhY$hgi%0JUmHnHujhgi%UaJ
