Summary

Amendment 3 to Recommendation ITU-T H.222.0 | ISO/IEC 13818-1 specifies the transport of bit-streams conforming to one or more profiles defined in Annex G of Recommendation ITU-T H.264 | ISO/IEC 14496-10 (fourth edition) over MPEG-2 Transport Streams as defined in Recommendation ITU-T H.222.0 | ISO/IEC 13818-1. It proposes extensions to Recommendation ITU-T H.222.0 | ISO/IEC 13818-1.

A number of use cases can be supported, if different video sub-bitstreams with different values of dependency_id of the scalable bit-stream are transported as different elementary streams (ES). This allows for de-multiplexing on Transport Stream (TS) level, which is the pre-requisite for selective access to a certain set of layers, selective content protection, or unequal error protection mechanisms. MPEG-2 TS already specifies the transport of Network Abstraction Layer (NAL) units conforming to one or more profiles defined in Annex A of Recommendation ITU-T H.264 | ISO/IEC 14496-10. This amendment makes extensions for supporting NAL units and bit-streams according to Annex G of Recommendation ITU-T H.264 | ISO/IEC 14496-10.
