JVET-Q0279 AHG8/AHG9: On alignment across layers [B. Choi, S. Wenger, S. Liu (Tencent)]

This contribution was discussed Saturday 11 January at 2030 in Track A (chaired by GJS).

Item 1 of this contribution belongs to this category.

Item 1 proposes that if the current picture is RASL, a picture referencing the current picture in the same AU shall be equal to RASL.

It was remarked that we do not require IRAP pictures to be aligned across layers, so it should be allowed for a RASL to reference a trailing picture in a reference layer. Thus, no action was taken on this.
