JVET-AP0213 AHG9: On implicit representations with the Gaussian splatting information SEI message [S. Lee, S. Sasse, Y. Berendsohn, Y. Sanchez, R. Skupin, T. M. Borges, C. Hellge, T. Schierl (HHI)]

Agreed to be included in TuC in joint meetings

JVET-AP0213-v2 (was discussed in Discussed in HLS track chaired by S. Deshpande from 18:25:18:40 CEST on 30 April 2026.

The yellow highlighted syntax is on top of JVET-AM0212.

It was asked if the syntax in this SEI uses anything from the JVET-AM0212 SEI. Very little information from there is used. The syntax includes a {…} section which also uses syntax from JVET-AM0212.

It was asked (for future) what is the pixel rate for this and JVET-AP0079 and JVET-AP0100-v5.

This also makes some additions to the NNPFC syntax and semantics, and NNPFA related process. It was suggested to create a version for integration which does not have {…}.

Agreed (also in HLS track) to include JVET-AP0213-v3 in TuC where the only change compared to the presented v2 will be to remove the {…} part syntax and fill it in.
