(EN) METHOD AND APPARATUS FOR INDICATING SWITCHING POINTS IN A STREAMING SESSION
(FR) PROCÉDÉ ET APPAREIL POUR INDIQUER DES POINTS DE COMMUTATION DANS UNE SESSION DE DIFFUSION EN CONTINU
Abrégé
(EN)
A method, apparatus, system and computer program product are provided to provide switching point information to facilitate switching between different representations of the media content. In an instance in which a content consumption device determines that a switch from a first representation to a second representation is merited, the content consumption device may identify the appropriate switching point from the switching point information provided by the server. The content consumption device may then request the second representation of the media content beginning at the switching point.
(FR)
L'invention concerne un procédé, un appareil, un système et un produit-programme informatique destinés à fournir des informations de point de commutation facilitant la commutation entre différentes représentations du contenu multimédia. Selon un exemple dans lequel un dispositif de consommation de contenu détermine la nécessité de commuter d'une première représentation à une seconde représentation, le dispositif de consommation de contenu peut identifier le point de commutation approprié à partir des informations de point de commutation fournies par le serveur. Le dispositif de consommation de contenu peut ensuite demander la seconde représentation du contenu multimédia à partir du point de commutation.
