The present invention provides a method (900) and device (100) in multimedia systems for efficiently segmenting information bitstreams from multiple media sources into variable length packets, and multiplexing and sending the packets to a shared communication link with low delay and low overhead. The packet segmentation and multiplexing are performed dynamically based on fullness of a set of information buffers that contain the information bitstreams to be transmitted, and delay-sensitivity of each information bitstream. The multi-discipline queuing scheme has been developed in this invention to control the dynamic packet segmenting and multiplexing process.
La présente invention concerne un procédé (900) ainsi qu'un dispositif (100) pour systèmes de communication multimédia. Ce système permet de segmenter efficacement les trains binaires d'informations, en provenance de plusieurs sources de média, en paquets de longueur variable, ainsi que de multiplexer et d'envoyer ces paquets sur une liaison de communication commune, avec un retard et une surcharge du système réduits. La segmentation et le multiplexage des paquets se font de manière dynamique à l'aide d'un ensemble de mémoires tampons qui contiennent les trains binaires d'informations à transmettre, et par la détection du retard de chaque train binaire d'informations. Le mécanisme de file d'attente multidisciplinaire dont il est question dans cette invention permet de gérer la segmentation dynamique en paquets et le processus de multiplexage.
