Abstract

The embodiments relate to a method comprising obtaining at least two bitstreams each comprising one or more independently decodable sub-bitstreams; determining identifiers of the one or more independently decodable sub-bitstream and a spatial relationship between the independently decodable sub-bitstreams of the at least two bitstreams; generating a description file, in which an indication of the relationship between the sub-bitstream identifiers of the independently decodable sub-bitstreams from the at least two bitstreams is included; encapsulating the at least two bitstreams into real-time protocol streams; and transmitting the real-time protocol packets comprising the at least two real-time protocol streams along with the description file indicating the relations between the independently decodable sub-bitstreams of the at least two bitstreams. There is also described a method comprising obtaining a description file comprising at least one mapping table, and two or more RTP media stream descriptions; determining a relationship between independently decodable sub-bitstreams by parsing the mapping table; requesting from a sender a portion of the two or more bitstreams; and receiving the requested portion of the two or more bitstreams.
