AHG9: DOI SEI support for target picture with alpha channel
Authors: Thibaud Biatek Nokia Jill Boyce Nokia Miska M. Hannuksela Nokia
Abstract
The DOI SEI message supports use of alpha channel pictures in the formation of a target picture. However, the target picture itself represents only texture. It is proposed to add support in the DOI SEI message for formation of a target picture alpha channel that is associated with the primary target picture. Formation of a target picture alpha channel enables usage of the DOI SEI message for generation of a standalone overlay, without the background video contained in the bitstream. Support for alpha target pictures also enables cascading of DOI SEI messages.
Meeting Notes
JVET-AK0100 AHG9: DOI SEI support for target picture with alpha channel [T. Biatek, J. Boyce, M. M. Hannuksela (Nokia)]

Consideration of this was chaired by S. Deshpande on 16 January 2025 at 18:45 PM.

The DOI SEI message supports use of alpha channel pictures in the formation of a target picture. However, the target picture itself represents only texture. It is proposed to add support in the DOI SEI message for formation of a target picture alpha channel that is associated with the primary target picture. Formation of a target picture alpha channel enables usage of the DOI SEI message for generation of a standalone overlay, without the background video contained in the bitstream. Support for alpha target pictures also enables cascading of DOI SEI messages.

The target picture has texture component but additionally the proposal can provide alpha channel for the target picture.

There was support for this proposal from a non-proponent.

Decision: Adopt.
