Channel changes between services with differing bandwidth in a switched digital video system. A services map published by the headend and distributed to all of the edge devices, allows a bandwidth requirement to be correlated with each request from a device in the home. The bandwidth requirement is passed upstream along with the request for service and is subject to a system resource management validation.
La présente invention concerne des changements de chaîne entre des services à bande passante différente dans un système vidéo numérique commuté. Une carte de services publiée par la tête de réseau et distribuée à tous les dispositifs périphériques permet de mettre en corrélation une demande de bande passante avec chaque demande d'un dispositif à domicile. La demande de bande passante est transmise dans le sens montant avec la demande de service et est soumise à une validation de gestion des ressources du système.
