This part of ISO/IEC 14496 specifies the storage format for AVC (ISO/IEC 14496-10 | ITU-T Rec. H.264) video streams. The storage of AVC content uses the existing capabilities of the ISO Base Media File Format but also defines extensions to support the following features of the AVC codec: - Switching pictures: To enable switching between different coded streams and substitution of pictures within the same stream. - Sub-sequences and layers: Provides a structuring of the dependencies of a group of pictures to provide for a flexible stream structure (e.g. in terms of temporal scalability and layering). - Parameter sets: The sequence and picture parameter set mechanism decouples the transmission of infrequently changing information from the transmission of coded macroblock data. Each slice containing the coded macroblock data references the picture parameter set containing its decoding parameters. In turn, the picture parameter set references a sequence parameter set that contains sequence level decoding parameter information.
