JVET-Y0008 JVET AHG report: High bit depth, high bit rate, and high frame rate coding (AHG8) [A. Browne, T. Ikai, D. Rusanovskyy, M. Sarwer, X. Xiu, Y. Yu]
Activities
The AHG used the main JVET reflector, jvet@lists.rwth-aachen.de, with [AHG8] in message headers, but no correspondence marked as AHG8 was sent between the 24th and 25th meetings.
The major area of work for the AHG in this meeting cycle was as follows:
- The development of conformance testing in coordination with AHG5. A revision of JVET-X2026 “Conformance testing for VVC operation range extensions (Draft 2)” was uploaded on 14th November 2021 and a notification was sent to the reflector.
- Updates to the draft text for the VVC version 2 extensions in coordination with AHG2. A revision of JVET-X2005 “VVC operation range extensions (Draft 5)” was uploaded on 12th November 2021.
There were 3 related related contributions for the 25th meeting.
Contributions
JVET-Y0049 “AHG2/AHG8: On the range extensions GCI flags”, Y.-K. Wang
JVET-Y0127 “AHG5: Editors' update on conformance testing for VVC operation range extensions”, D. Rusanovskyy, T. Hashimoto, H.-J. Jhu, I. Moccagatta, M. G. Sarwer, Y. Yu
JVET-Y0190 “AHG2/AHG8: Suggestions for the operation range extensions GCI”, J. Gan, Y. Yu, H. Yu
Recommendations
The AHG recommended the following:
- To proceed with finalization of VVC version 2 at this meeting;
- To review all related contributions;
- To continue high bit depth, high bit rate, and high frame rate studies.
It was pointed out that potentially a combination of scalability with extended bit depth could be tested with the VTM software.
