JVET-U0118 Crosscheck of JVET-U0078 (AHG9: Out-of-loop luma mapping with chroma scaling using APS or SEI message parameters signalling) [Fangjun Pu (Dolby)] [late]

JVET-U2024 Exploration Experiment on Enhanced Compression beyond VVC capability [ V. Seregin, J. Chen, S. Esenlik, F. Le Léannec, L. Li, M. Winken, J. Ström, X. Xiu, K. Zhang] [WG 5 N 41] (2021-02-15)

Plans for this experiment are documented in detail in JVET-U0140. An initial draft was reviewed and approved. A telco was planned to be organized by AHG12 before finalization. Initial drafts of the experiment descriptions should be made available shortly after the meeting.

Future meeting plans, expressions of thanks, and closing of the meeting

Future meeting plans were established according to the following guidelines:

• Meeting under ITU-T SG 16 auspices when it meets (ordinarily starting meetings on the Wednesday of the first week and closing it on the Wednesday of the second week of the SG 16 meeting – a total of 8 meeting days), and
• Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 5 auspices when it meets (ordinarily starting meetings on the Friday prior to such meetings and closing it at lunchtime on the last day of the WG 5 meeting – a total of 7.5 meeting days).

In cases where an exceptionally high workload is expected for a meeting, an earlier starting date may be defined. In case of online meetings, no sessions should be held on weekend days. This may imply an earlier starting date as well.

Some specific future meeting plans (to be confirmed) were established as follows:

• Tue. 20 – Wed. 28 April 2021, 22^nd meeting, online under ITU-T SG 16 auspices.
• Wed. 7 – Fri. 16 July 2021, 23^rd meeting, online under ISO/IEC SC 29 auspices.
• Fri. 8 – Fri. 15 October 2021, 24^thmeeting...

JVET-U0009 JVET AHG report: SEI message studies (AHG9) [J. Boyce, S. McCarthy, C. Fogg, P. de Lagrange, A. Luthra, G. J. Sullivan, A. Tourapis, Y.-K. Wang, S. Wenger]

At the 20th JVET meeting, the AHG on SEI message studies was established with the following mandates:

• Study the SEI messages in VSEI, VVC, HEVC and AVC.
• Collect software and SEI showcase and usage information for SEI messages, including encoder and decoder implementations and bitstreams for demonstration and testing.
• Identify potential needs for additional SEI messages.
• Study SEI messages defined in HEVC and AVC for potential use in the VVC context.
• Coordinate with AHG3 for software support of SEI messages.

The following contributions were identified as related to AHG9. It is noted that some of the contributions were not identified as AHG9 in their titles.

• JVET-U0045 AHG9: Picture output suppression SEI message [M. Pettersson, R. Sjöberg, M. Damghanian, J. Ström (Ericsson)]
• JVET-U0049 AHG2: Some errata items for AVC [Y.-K. Wang (Bytedance), G. J. Sullivan (Microsoft)] (Errata item 1 relates to AHG9)
• JVET-U0053 AHG9/AHG11: Level information for super-resolution neural network [T. Chujoh, E. Sasaki, T. Suzuki, T. Ikai (Sharp)]
• JVET-U0078 AHG9: Out-of-loop luma mapping with chroma scaling using APS or SEI message parameters signalling [E. François, P. de Lagrange, F. Le Léannec (InterDigital)]
• JVET-U0082 AHG9: Scalability dimension SEI message and three HEVC SEI messages [Y.-K. Wang, L. Zhang, K. Zhang, Z. Deng, Y. Wang (Bytedance), A. Vetro (MERL), M. Mrak, S. Blasi (BBC)]
• JVET-U0083 Signalling of decoder initialization...
