Title (EN) OFFLOADING A DISTRIBUTION SERVER TASK TO A MEDIA GATEWAY
(FR) TRANSFERT D'UNE TÂCHE DE SERVEUR DE DISTRIBUTION À UNE PASSERELLE MULTIMÉDIA
Abstract:
(EN) A server offloads one or more tasks to a first media gateway. The server receives, from the first media gateway that is receiving a video stream of a television channel, a first message that indicates that the first media gateway is eligible to process a request for media content of the television channel that otherwise would be processed by the server. The server receives, from a second media gateway, a request for media content of the television channel. The server transmits, to the second media gateway, a redirection response that instructs the second media gateway to request the media content from the first media gateway.
(FR) La présente invention concerne un serveur qui transfère une ou plusieurs tâches à une première passerelle multimédia. Le serveur reçoit, de la première passerelle multimédia qui reçoit un flux vidéo d'un canal de télévision, un premier message qui indique que la première passerelle multimédia est prête à traiter une demande de contenu multimédia du canal de télévision qui serait autrement traitée par le serveur. Le serveur reçoit, d'une seconde passerelle multimédia, une demande de contenu multimédia du canal de télévision. Le serveur transmet, à la seconde passerelle multimédia, une réponse de redirection qui ordonne à la seconde passerelle multimédia de demander le contenu multimédia à partir de la première passerelle multimédia.
