JVET-AC0004 JVET AHG report: Test material and visual assessment (AHG4) [V. Baroncini, T. Suzuki, M. Wien (co-chairs), S. Liu, S. Puri, A. Segall, P. Topiwala, S. Wenger, J. Xu, Y. Ye (vice-chairs)]
Activities
Verification test preparation for VVC multilayer coding
A teleconference was organized by AG5 and JVET AhG4 2022-12-16 08:30h UTC. The topic was the Verification Test preparation for VVC Multilayer Coding. The report of the AhG meeting is available in JVET-AC0042.
Subjective test preparation for film grain synthesis
The teleconference was organized by AG5 and JVET AhG4 2022-12-16 17:00h UTC. The topic was the preparation for subjective testing of film grain synthesis. The report of the AhG meeting is available in JVET-AC0043.
Test sequences
The test sequences used for CfP/CTC are available on ftp://jvet@ftp.ient.rwth-aachen.de in directory “/ctc” (accredited members of JVET may contact the JVET chairs for login information).
In the report period, test material related to the CTC for SHVC has been made available in that directory.
Due to copyright restrictions, the JVET database of test sequences is only available to accredited members of JVET (i.e., members of ISO/IEC MPEG and ITU-T VCEG).

Recommendations
The AHG recommended:
- To review and discuss the input related to the verification test plan for VVC multilayer coding proposed in JVET-AC0145.
- To review and discuss the input related to the subjective tests for the FGC SEI message proposed in JVET-AC0181.
- Review JVET-AC0041 and JVET-AC0044 in a joint meeting with AG5 and WG7
- Review JVET-AC0267 in a joint session with AG 5
- To collect volunteers to conduct further verification tests, including volunteers to encode.
- To continue to discuss and to update the non-finalized categories of the verification test plan, including those which have not been addressed yet.
- To review the set of available test sequences for the verification tests and potentially collect more test sequences with a variety of content.
- To continue to collect new test sequences available for JVET with licensing statement.
It was suggested that the aspects targeted in JVET-AC0041 should be discussed at a higher level with other WGs (2, 4, 7) and VCEG first, e.g. whether it is desirable to develop dedicated tools or profiles for PCC in JVET.
