METHOD AND DEVICE FOR REORDERING AND MULTIPLEXING MULTIMEDIA PACKETS FROM MULTIMEDIA STREAMS BELONGING TO INTERRELATED SESSIONS

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to a method and a device for reordering and multiplexing multimedia packets from multimedia streams belonging to interrelated sessions and particularly for data streams encoded with a scalable video codec, which are transported by a real-time transport protocol (RTP). The method for reordering and multiplexing multimedia packets from multimedia data streams belonging to interrelated sessions includes a step of searching within the packets of a stream having the highest frame rate amongst said multimedia streams, for a common timing variable of the packet associated with the next frame of the multimedia data, in a predetermined order related to the encoding process with which said data were encoded, and a step of providing the packets in said predetermined order between said sessions in the order of the session interdependency.;EFFECT: providing a method of said known type, but which can solve the said problems of computational complexity, increased bandwidth or need to cope with different frame rates, for retrieving packets of eg RTP/SVC sessions in the non-interleaved mode and/or single NAL unit mode.;13 cl, 10 dwg
