Abstract
This document contains the draft text for changes on new profiles, colour descriptors, and SEI messages for the 5th edition of the High Efficiency Video Coding (HEVC) standard (Rec. ITU-T H.265 | ISO/IEC 23008-2). The changes include: 1) the support of four new profiles, namely the Multiview Main 10, Multiview Monochrome, Multiview Monochrome 10, and Multiview Monochrome 12 profiles; 2) the support of three additional colour type identifiers; 3) the HEVC-specific supports for some supplemental enhancement information (SEI) messages that may be included in VC bitstreams but are not to be specified in the VC specification, and 4) some technical corrections and editorial improvements to the 5th edition text of HEVC. The SEI messages are the neural network post-filter characteristics (NNPFC) SEI message, the neural-network post-filter activation (NNPFA) SEI message, and the phase indication SEI message, that are to be specified in the 3rd edition of the Versatile Supplemental Enhancement Information messages for coded video bitstreams (VSEI) standard (ITU-T H.274 | ISO/IEC 23002-7).

JVET-AF0063 On MV-HEVC profiles [Y.-K. Wang, H. Liu, L. Zhang, S. Jiao, C. Hu, J. Cui, G. Xu (Bytedance)]
It was asserted that, although the syntax of MV-HEVC allows for an output layer set (OLS) in an MV-HEVC bitstream to have both texture layers and depth layers, the profile definitions do not allow this. Recently, applications have come up, e.g., virtual reality, that benefit from all the following three aspects simultaneously: 1) using inter-view prediction between different views, 2) having depths associated with the coded views to be available to the decoder and the renderer, and 3) using existing HEVC hardware encoder/decoder designs. It is also asserted that in such applications it is desirable that the bit depth of the depth component can be of up to 16 bits.
This contribution proposes the following:
- Update the definitions of the four new profiles, namely the Multiview Main 10, Multiview Monochrome, Multiview Monochrome 10, and Multiview Monochrome 12 profiles, to allow for an OLS containing a layer conforming to such a profile to have both texture layers and depth layers.
- Add a new profile, named the Multiview Monochrome 16 profile, where it is also allowed for an OLS containing a layer conforming to this profile to have both texture layers and depth layers.
The proposed changes, including some minor editorial changes not summarized above, are included in an attachment, with all the proposed changes marked relative to JVET-AE1006-v1.
It was reported that the existing definition of the new Multiview profiles does not support carriage of depth maps. A text is...
Decisions
It was concluded to keep the definition for the Multiview Main 10 profile as it is in terms of encoding depth maps. This also retains the same concept as in the 8 bit profile.
Contributions in this area were discussed at 1735–1745 on Thursday 19 Oct. 2023 (chaired by JRO).

Compare the VVC documents with the VVC software and resolve any discrepancies that may exist, in collaboration with the software AHG,
Encourage the use of the issue tracker to report issues with the text of both the VVC specification text and the algorithm and encoder description,
Continue to improve the editorial consistency of VVC text specification and Test Model documents,
Ensure that, when considering changes to VVC, properly drafted text for addition to the VVC Test Model and/or the VVC specification text is made available in a timely manner,
Review bug tickets, and other AHG2 related inputs and act on them if found to be necessary.

JVET-AE0294 Film Grain BOG Report [W. Husak (BoG coordinator)]
The results of first BoG meeting were presented in JVET on Saturday 15 July at 1445, as shown below.
Elements needed included a Denoiser, FG Analyser, and FG Synthesizer. With the GT approach, the denoiser could in the first place be skipped, and it could be investigated whether the artistic film grain comes with the content could be equivalently generated with the FGS SEI. This would not be fully realistic, but denoiser and analysis could be added later.
Another application is coding artefact hiding by dithering. In that case, an objective metric is more urgently needed.
It was mentioned that in practice also quant matrices are often used together with film grain (example x.265?).
The GT data set could be used in the subjective quality testing of SEI for category 2, and also for category 1 -> viewing if possible on Wednesday...
