Abstract:
1. A method of indicating bit stream subsets in a compressed layered video bit stream comprising a plurality of bit stream subsets, each bit stream subset representing a certain layer of the compressed layered video bit stream, the method comprising: receiving the compressed layered video bit stream; dividing the compressed layered video bit stream into video packets, wherein each video packet comprises either one of video data or supplemental information; marking each video packet with a single subset identifier of a plurality of subset identifiers, wherein each subset identifier of the plurality of subset identifiers is associated with a corresponding bit stream subset of the plurality of bit stream subsets, for associating each video packet with the corresponding bit stream subset and with parameters describing properties of the corresponding bit stream subset; and providing at least one video representation definition, each video representation definition comprising at least one relevant subset identifier, wherein the bit stream subsets associated with the at least one relevant subset identifier together form a decodable video representation.
