The file format for storage of SVC content, as defined in Annexes A to E, and the file format for storage of MVC content, as defined in Annexes B to F, use the existing capabilities of the ISO base media file format and the plain AVC file format (i.e. the file format specified in Clauses 2 to 5 not including SVC and MVC supports specified in Annexes A to F). In addition, the following new extensions, among others, to support SVC- and/or MVC-specific features are specified.
- Scalable or multiview grouping:
a structuring and grouping mechanism to indicate the association of NAL units with different types and hierarchy levels of scalability.
- Aggregator:
a structure to enable efficient scalable grouping of NAL units by changing irregular patterns of NAL units into regular patterns of aggregated data units.
- Extractor:
a structure to enable efficient extraction of NAL units from other tracks than the one containing the media
data.
- Temporal metadata statements:
structures for storing time-aligned information of media samples.
- AVC compatibility:
a provision for storing an SVC or MVC bitstream in an AVC compatible manner, such that the AVC compatible base layer can be used by any plain AVC file format compliant reader.
