Title (EN) METHOD AND SYSTEM FOR FAST CHANNEL SWITCHING USING STANDARD RTSP MESSAGES
(FR) PROCÉDÉ ET SYSTÈME POUR UNE COMMUTATION DE CANAL RAPIDE À L’AIDE DE MESSAGES RTSP STANDARD
Abstract: front page image
(EN)Method and system for performing fast channel switching in client-server systems, in which live media streams sent by a streaming server under the RTSP protocol are played by the client, are described. The seek functionality in the media player is overloaded to provide switching between live media streams by using standard RTSP message in-band within a single RTSP session.
(FR)La présente invention concerne un procédé et un système permettant d’effectuer une commutation de canal rapide dans des systèmes client – serveur, dans lesquels des flux multimédia en direct envoyés par un serveur en continu sous le protocole RTSP sont reproduits par le client. La fonctionnalité de recherche dans le diffuseur multimédia est surchargée pour assurer une commutation entre des flux multimédia en direct par l’utilisation d’un message RTSP standard dans la bande dans une seule session RTSP.
