JVET-AM0174 AHG9: On general SEI payload constraints [Y. Sanchez, R. Skupin, T. M. Borges, K. Sühring, C. Hellge, T. Schierl (Fraunhofer HHI)]

Presented at 1230 on Friday 27 June 2025.

This contribution proposes to update the excluded payloadTypes from the constraint in subclause D.2.2 in VVC v4, which disallows multiple SEI messages with the same payloadType within an AU.

It was suggested that the text description SEI message should also be added to the list. In general, it seems like any SEI messages with an ID should be added to the list.

Decision: Adopt with addition of text description SEI (219).

General discussion during 1600–1615 on Thursday 26 June 2025 (chaired by J. Boyce).

VSEI v4 is intended for FDIS in October. There is a preference for design stability. Bug fixes and editorial improvements are OK. We intend to be cautious about adoptions that change the design. Small items with clear benefits may be considered.
