JVET-V0009 JVET AHG report: SEI message studies (AHG9) [J. Boyce, S. McCarthy, C. Fogg, P. de Lagrange, A. Luthra, G. J. Sullivan, A. Tourapis, Y.-K. Wang, S. Wenger]

At total of 16 contributions are identified relating to AHG9, of which:

• 8 contributions relate to the mandate on the potential needs for additional SEI messages;
• 5 contributions relate to the mandate on SEI messages previously adopted or specified in AVC, HEVC, VVC, or VSEI;
• 1 contribution relates to the mandate on possible need of mandatory post processing in the context of SEI messages; and
• 2 contributions are crosschecks of proposed software that relate to the mandate on showcase and usage information for SEI messages

The regular JVET e-mail reflector was used for discussions (jvet@lists.rwth-aachen.de) with [AHG9] in message headers. There were no emails besides the AHG kickoff message sent to the JVET reflector during the AHG period.

The AHG recommended to review all related contributions and continue SEI messages studies.
