ABSTRACT:
Compression parameter sets are stored in files separate from the main AV or transmitted separately and prior to any subsequent transmission of AV data. The scope of parameter set identifiers is limited to not more than a Program Chain. Either existing files are extended by including the compression parameter sets directly, or separate files containing the compression parameter sets are created. In order to support easy authoring of compound content, it is proposed to amend each compression parameter set or groups of such parameter sets with scope period information, which can be based on time stamps, on file names, or on sector numbers on the disc. It is additionally proposed to employ an indirect referencing mechanism, where parameter set identifiers are referring to secondary tables, and where the entries of secondary tables are defined to be themselves identifiers referring in turn to entries of a common parameter set table provided once.
