Title (EN) MULTIPLE BUFFERED CHANNEL IP MULTICAST
(FR) MULTIDIFFUSION SELON UN PROTOCOLE INTERNET PAR CANAUX MULTIPLES TAMPONNES
Abstract:
(EN) A method to allow a user to change multicast channels received over the Internet without reception delay. The method for implementing the invention includes a multicast generating system (12) coupled to a public or private network (14), such as the internet. A network router (16) is coupled to the network and one or more user systems (20). Multicast channels are monitored for their amount of usage by the user. The multicast broadcasts with the most monitored usage are buffered for quick access. A multicast broadcast is buffered according to a determined available bandwith for a user system. Buffering of one or more multicast broadcasts is discontinued if the network is determined to be too congested.
(FR) Cette invention concerne un procédé permettant à un utilisateur de changer de canal de multidiffusion reçu par Internet sans retard de réception. On surveille l'utilisation que fait l'utilisateur des canaux à multidiffusion. Les canaux à multidiffusion dont la surveillance révèle qu'ils sont le plus souvent utilisés sont assortis de tampons qui en rendent l'accès plus rapide. Une émission multidiffusée est tamponnée en fonction d'une largeur de bande disponible pour un système utilisateur. Le tamponnage d'une ou de plusieurs canaux à multidiffusion est interrompu s'il apparaît que le réseau est embouteillé.
