AHG12: On CBR subpicture extraction
Authors: Robert Skupin HHI Yago Sanchez HHI Karsten Suehring HHI T. Schierl HHI
Abstract
This contribution proposes several options to specify an extraction process for subpictures that allows a CBR mode after extraction.
Meeting Notes
JVET-Q0404 AHG12: On CBR subpicture extraction [R. Skupin, Y. Sanchez, K. Sühring, T. Schierl (HHI)]

This contribution was discussed Wednesday 15 January at 1900 in Track A (chaired by GJS). It had not been reviewed in the HLS BoG.

It proposes a way to associate filler data NAL units and filler payload SEI messages with subpictures. It was noted that these already have an association defined for association with VCL NAL units, and this should be sufficient to associate them with subpicture regions. Using this association and adding a CBR flag for the subpicture level information SEI message should be sufficient. The extraction process should account for the association. Decision (BF/cleanup): Adopt CBR flag and semantics and extraction process as described. Text is to be integrated into revision of JVET-Q0397.
