The default sub bit-stream for operating point of operating point layer identifier and NAL unit of the NAL unit header and SEI NAL unit of the given that the header of the given the time identifier the definition and expression. When the SEI message is suitable for when nested in the default sub bit-stream said device in operation to the default sub bit-stream and using the nested and SEI information.

A device determines based at least in part on a syntax element in a scalable nesting supplemental enhancement information (SEI) message encapsulated by an SEI Network Abstraction Layer (NAL) unit whether a nested SEI message encapsulated by the scalable nesting SEI message is applicable to a default sub-bitstream. The default sub-bitstream is an operation point representation of an operation point defined by a layer identifier specified in a NAL unit header of the SEI NAL unit and a temporal identifier specified in the NAL unit header. When the nested SEI message is applicable to the default sub-bitstream the device uses the nested SEI message in an operation on the default sub-bitstream.
