Title (EN) TIMELY RECOVERY FOR MEDIA ON DEMAND STREAMING
(FR) RECUPERATION EN TEMPS OPPORTUN POUR TRANSMISSION MULTIMEDIA A LA DEMANDE EN CONTINU
Abstract:
(EN) For a media on demand (MoD) session where content is streaming from a first content server to a media agent, a server manager operates to minimize or eliminate the impact of a failure affecting the streamed content. The server manager will monitor at least the first content server, and when a failure is detected, initiate the transition from the first content server to a second content server. In particular, the server manager will directly or indirectly ensure that the media agent has sufficient information to establish another streaming session for the MoD session with the second content server. The transition is preferably facilitated in real time and within a short enough time period to eliminate or at least minimize the effect of the media ultimate presentation to the subscriber.
(FR) Selon l'invention, pour une session multimédia à la demande (MoD) dans laquelle un contenu est transmis en continu d'un premier serveur de contenu vers un agent multimédia, un gestionnaire de serveur fonctionne pour réduire au minimum ou éliminer l'impact d'une défaillance touchant le contenu transmis en continu. Le gestionnaire de serveur surveille au moins le premier serveur de contenu et, lorsqu'une défaillance est détectée, initie la transition du premier serveur de contenu vers un second serveur de contenu. En particulier, le gestionnaire de serveur s'assure directement ou indirectement que l'agent multimédia présente suffisamment d'informations pour établir une autre session de transmission en continu pour la session MoD avec le second serveur de contenu. La transition est de préférence assurée en temps réel et dans un temps assez court afin d'éliminer ou au moins de réduire au minimum l'effet de la dernière présentation de multimédia à l'abonné.
