Scalable nesting SEI message for given layer

By introducing the scalable nesting all_layers_flag flag in the video encoding system, the compliance test errors caused by the scalable nesting SEI message application flag in multi-layer video encoding are solved, and higher encoding efficiency and functionality are achieved.

Abstract

To provide a method for applying scalable nesting supplemental enhancement information (SEI) messages used to support coding layers in a multi-layer bitstream.SOLUTION: A bitstream received at a decoder includes a scalable nesting supplemental enhancement information (SEI) message in one or more layers and in the current SEI Network Abstraction Layer (NAL) unit. The scalable nesting SEI message includes a scalable nesting all layers flag (SN all_layers_flag) that specifies whether the scalable nesting SEI message applies to the scalable nested SEI message and all layers with layer identifiers (Ids) that are greater than or equal to a layer identifier (Id) of the current SEI NAL unit.SELECTED DRAWING: Figure 7
