JVET-Q0627 On Dependent Quantization: combination of JVET-Q0243 and JVET-Q0227 [P. Le Léannec, E. François (InterDigital)] [late]

This contribution relates to Dependent Quantization and combines the proposals from JVET-Q0243 on using 8 quantization states instead of 4 states in the current VTM, and JVET-Q0227 on using an qP-dependent offset when applying the scaling process for transform coefficients.

The reported psnr-Y, U, V BD-rate variations compared to VTM7.0 when using 8 quantization states are:

AI: –0.47%, 0.42%, 0.43% (Y, Cb, Cr) at 109% encoding time and 100% decoding time
RA: –0.38%, –0.05%, –0.12% (Y, Cb, Cr) at 106% encoding time and 101% decoding time
LB: –0.58%, 0.18%, 0.36% (Y, Cb, Cr) at 106% encoding time and 101% decoding time

No need for presentation.

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 Tuesday of the first week and closing it on the Wednesday of the second week of the SG 16 meeting – a total of 9 meeting days), and
• Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 11 auspices when it meets (ordinarily starting meetings on the Wednesday prior to such meetings and closing it at lunchtime on the last day of the WG 11 meeting – a total of 9.5 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. 15 – Fri. 24 April 2020, 18^th meeting under WG 11 auspices in Alpbach, AT (post-meeting note: the planned Alpbach meeting was later converted to a teleconference-based meeting in response to the COVID-19 pandemic).
• Tue. 23 June – Wed. 1 July 2020, 19^th meeting under ITU-T auspices in Geneva, CH.
• Wed. 7 – Fri. 16 October 2020, 20^th meeting under WG 11 auspices in Rennes, FR.
• Wed. 6 – Fri. 15 January 2021, 21^st meeting under WG 11 auspices in Capetown, ZA.

The agreed document deadline for the 18^thJVET meeting was planned to be Wednesday 8 April 2020. Only HLS topics were planned to be considered on...
