JVET-T0082 New HLG sequences for high bit-depth video coding [K. Kondo, M. Ikeda, A. Browne (Sony)]

This contribution was discussed briefly in session 20 at 2010 on Thursday 15 October.

This contribution proposes new HLG (Hybrid Log-Gamma) test sequences for high bit-depth video coding. This provides information on the test sequences, which are resolution, frame rate, chroma format, bit-depth, frame count and the coding results of VTM-10.0 compared to HM-16.22-RExt.

This contribution was discussed in the HBD BoG (see section 5.1.1, esp. JVET-T0124).

JVET-T2023 EE on Neural Network-based Video Coding [E. Alshina, S. Liu, W. Chen, Y. Li, R.-L. Liao, Z. Ma, H. Wang] [WG 5 [N 25] (2020-10-30)

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.

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

• Wed. 6 – Fri. 8 and Mon 11 – Fri. 15 January 2021, 21^st meeting under SC 29 auspices as a teleconference (7.5 meeting days).
• Wed. 21 – Wed. 28 April 2021, 22^nd meeting under ITU-T auspices in Geneva, CH.
• Fri. 9 – Fri. 16 July 2021, 23^rd meeting under SC 29 auspices in Prague, CZ.
• Fri. 8 – Fri. 15 October 2021, 24^th meeting under SC 29 auspices in Antalya, TR.

The agreed document deadline for the 21^st JVET meeting was planned to be Wednesday 30 Dec. 2020.
