Abstract
This report summarizes the activities of the AhG4 on Test material and visual assessment that have taken place between the 40th and 41st JVET meetings.
Meeting Notes
JVET-AO0004 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)]
  1. Preparations for the Joint Call for Evidence on video compression with capability beyond VVC

AHG4 supported the activities of AHG17 and prepared for the on-site testing activity.

  1. Test sequences

The set of JVET test sequences is hosted at 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. The password for the site is updated after each meeting with the Zoom password for that meeting. The tentative schedule for the changes is as follows:

  • After the April meeting, the password changes on 1st of June
  • After the July meeting, the password changes on 1st of September.
  • After the October meeting, the password changes on 1st of December.
  • After the January meeting, the password changes on 1st of March.

Recommendations

The AHG recommended:

  • To take into account the proposed test sequences in the preparation of the CfP on video compression with capability beyond VVC.
  • To continue to discuss and to update the non-finalized categories of the verification test plan for multilayer VVC based on JVET-AO0215.
  • 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.
