JCTVC-J0245 SEI Message for profile and level signaling for temporal scalability and extensions [J. Boyce, D. Hong, W. Jang]
An SEI message is proposed for the base HEVC specification, to optionally indicate profiles and levels for sub-bitstreams associated with temporal sub-layers. This contribution updates the proposed syntax of prior contribution JCTVC-I0231 to use the new profile indicators adopted in JCTVC-I0499. The proposed SEI message can also be extended for scalable and multiview extensions with optional profile & level indicators for each layer and temporal sub-layer combination. For the scalable and multiview extensions, a re-definition of the maximum pixel throughput limit level constraint in the SPS is proposed, such that the constraint applies only to the individual layer, and not the full sub-bitstream corresponding to that target layer_id, enabling the same SPS to be referred to by multiple layers.
Too early to decide on this before the concept of VPS/SPS signalling is finalized.
Closed by actions take on BoG output.
