JVET-AK0004 JVET AHG report: Test material and visual assessment (AHG4) [V. Baroncini, T. Suzuki, M. Wien (co-chairs), W. Husak, S. Iwamura, P. de Lagrange, S. Liu, X. Meng, S. Puri, A. Segall, S. Wenger (vice-chairs)]
Activities
Verification tests for VVC multilayer coding
The verification test plan has been updated to output JVET-AJ2021 of the previous JVET meeting.
Subjective quality testing of FGC SEI message
A report on subjective quality testing of FGC SEI message has been produced as output document JVET-AJ2037. The report includes the results and findings from expert viewing activities at the 35th and 36th JVET meetings.
The plan for subjective quality testing has been updated as output JVET-AJ2022 of the previous JVET meeting.
Test sequences
The server providing JVET test sequences has been updated. The new site is https://vqa.lfb.rwth-aachen.de. A mirror of this site is available at https://datacloud.hhi.fraunhofer.de with the same login credentials. The directory structure of the previous ftp server has been maintained. The test sequences used for CfP/CTC are available in directory “/ctc”.
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). Members of JVET may contact the JVET chair for login information. It is suggested to update the password for the site after each meeting with the Zoom password of that meeting.

Recommendations
The AHG recommended:
- To review the input contributions related to AHG4 during the meeting.
- To progress the work in AHG17 towards setting up a test set suitable for performance assessment of video compression technology beyond the JVET CTC.
- To continue to discuss and to update the non-finalized categories of the verification test plan for multilayer VVC and the subjective quality test plan for FGC, including those which have not been addressed yet.
- To collect volunteers to conduct further verification tests and subjective quality tests.
- To collect volunteers to actively contribute to the verification test development.
- To review the set of available test sequences for the verification tests as well as subjective quality 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.
