scope:

This Recommendation defines the procedures for use of advanced video codecs, including those based on [ITU-T H.264], in ITU-T H.300-series terminals, including ITU-T H.310, ITU-T H.320, ITU-T H.321, ITU-T H.322, ITU-T H.323 and ITU-T H.324 terminals. Such procedures include control, indication, capability exchange, and transport mechanisms.

Additionally, this Recommendation defines generic extended video control, indication, and capability signalling, applicable for use with all video codecs used in ITU-T H.300-series multimedia terminals.

Annex A specifies ITU-T H.264 transport for ITU-T H.323 systems, including Annex G of [ITU-T H.264] (Scalable Video Coding).

Annex B specifies a reduced-complexity decoding process to be applied to ITU-T H.264 Baseline profile bitstreams when such use has been negotiated using [ITU-T H.241].
