Abstract
This contribution describes additional study of a new SEI message named Colour Transform Information (CTI) SEI message, proposed in JVET-U0078. The SEI message signals mapping parameters that can apply to the decoded pictures. The mapping can operate intra-component (for luma and chroma) or inter-component (for chroma). In this contribution, the CTI has been tested as a mandatory process for out-of-loop mapping for HDR-PQ content. Tests without and with LMCS have been made. The best results are obtained with CTI and LMCS both applied. BD-rate variations compared to VTM12.0, for the CTCs HDR PQ content, are reported in the table below, for AI, RA, LB and LD configurations.

JVET-V0108 AHG9: Colour Transform Information SEI message [E. François, M. Radosavljević, P. de Lagrange, F. Le Léannec (InterDigital)]
This contribution was discussed in sesssion 16b at 2330 on Friday 23 April 2021 (chaired by GJS).
This contribution describes additional study of a new SEI message named colour transform information (CTI) SEI message, proposed in JVET-U0078. The SEI message signals mapping parameters that can apply to the decoded pictures. The mapping can operate intra-component (for luma and chroma) or inter-component (for chroma). In this contribution, the CTI has been tested as a mandatory process for out-of-loop mapping for HDR-PQ content. Tests without and with LMCS were reported. The best results were reportedly obtained with CTI and LMCS both applied. BD-rate variations compared to VTM12.0, for the CTCs HDR PQ content, are reported in the table below, for AI, RA, LB and LP configurations.
DE100 | PSNR-L | wPsnrY | wPsnrU | wPsnrV | psnrY | psnrU | psnrV | EncT | DecT | |
AI | -0.46% | -0.91% | -0.30% | -5.27% | -6.21% | 0.40% | -1.79% | -2.15% | 106% | 99% |

* LB and LP configuration is not part of the HDR CTCs. (This was suggested to be just to make the simulations faster.) It was pointed out that the two LD configurations are not included in some of the other “specialized” CTC, such as 360, 444.
The proponent emphasized that low delay is an important use case.
No benefit (or not much benefit) was reported for HLG content and SDR content.

Abstract
This contribution reports the cross-checking results for contribution JVET-V0108 on Colour Transform Information SEI message [1]. The cross-checking tests were performed for HDR PQ content under CTC conditions [2] for the second test which enables both CTI-SEI and LMCS. All results match the results provided in JVET-V0108.

Non-SEI HLS aspects (3)
Contributions in this area were initially discussed in session 16b at 0030–0120 UTC on Saturday 24 April 2021 (chaired by GJS). The notes of one contribution, JVET-V0109, were moved to section 4.13 from this section since the contribution seemed more a matter of system interface requirements than high-level syntax.

Abstract
This report summarizes the activities of the AhG3 on Test model software development that has taken place between the 23rd and 24th JVET meetings.
The mandates given to the AHG are:
- Coordinate development of test model (VTM, HM, SCM, SHM, HTM, MFC, MFCD, JM, JSVM, JMVM, 3DV-ATM, 360Lib, and HDRTools) software and associated configuration files.
- Produce documentation of software usage for distribution with the software.
- Enable software support for recently standardized additional SEI messages.
- Discuss and make recommendations on the software development process.
- Propose improvements to the guideline document for developments of the test model software.
- Perform comparative tests of test model behaviour using common test conditions.
- Suggest configuration files for additional testing of tools.
- Investigate how to minimize the number of separate codebases maintained for group reference software.
- Coordinate with AHG on Draft text and test model algorithm description editing (AHG2) to identify any mismatches between software and text, and make further updates and cleanups to the software as appropriate.
- Prepare drafts of merged CTC documents for HM and VTM, as applicable.
The software model versions prior to the start of the meeting were:
- VTM 14.0 (Aug. 2021)

Decisions
The AHG recommended to:
Approve JVET-V1002, JVET-V1004, JVET-V2002, JVET-V2005, and JVET-V2006 documents as JVET outputs,
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 AHG2 related contributions (if any) and act on them if found to be necessary.

For the organization and planning of its future work, the JVET established 12 “ad hoc groups” (AHGs) to progress the work on particular subject areas. At this meeting, 1 Core Experiment (CE) and 2 Exploration Experiments (EE) were defined. The next eight JVET meetings were planned for Wed. 7 – Fri. 16 July 2021, online under ISO/IEC JTC 1/SC 29 auspices, during Fri. 8 – Fri. 15 October 2021 as a mixed-mode meeting under ISO/IEC JTC 1/SC 29 auspices in Antalya, TR, during January 2022 under ITU-T SG16 auspices in Geneva, CH, during Fri. 22 – Fri. 29 April 2022 under ISO/IEC JTC 1/SC 29 auspices, location t.b.d., during Fri. 15 – Fri. 22 July 2022 under ISO/IEC JTC 1/SC 29 auspices in Cologne, DE, during October 2022 under ITU-T SG16 auspices in Geneva, CH, during January 2023 under ISO/IEC JTC 1/SC...

JVET-V0112 AHG9: On Bitstream Properties Signalling for Decoder Initialization [S. Deshpande (Sharp)]
This contribution was discussed in sesssion 18b at 1530 on Monday 26 April 2021 (chaired by GJS).
It is proposed to signal picture storage and picture format related information about CVSs in the bitstream to help the decoder initialization.
It is proposed to signal picture storage and picture format related information about CVSs in the bitstream to help the decoder initialization. In this document this information is called bitstream properties information.
It is asserted that signalling information which provides maximum required decoder resources for decoding a bitstream allows a decoder to allocate enough resources (e.g. memory/ DPB space) which can be used to decode the entire bitstream. Thus, need to deallocate and reallocate memory when decoding each CVS of a bitstream may be avo...
