Title (EN) SYSTEM AND METHOD FOR MANAGING ADJACENT CHANNELS IN AN ADAPTIVE STREAMING ENVIRONMENT
(FR) SYSTÈME ET PROCÉDÉ DE GESTION DE CANAUX ADJACENTS DANS UN ENVIRONNEMENT DE DIFFUSION ADAPTATIVE EN CONTINU
Abstract:
(EN) A system and method for managing adjacent channels in an adaptive streaming environment. One or more adjacent channels way be defined for a client device relative to a current streaming channel, wherein the client device is configured to pre-fetch metadata and initialization information for the defined adjacent channels based on bandwidth, conditions, buffer conditions, etc. When a channel is changed, the client device is operative to use the pre-fetched data to quickly obtain encoded media content for rendering.
(FR) Système et procédé de gestion de canaux adjacents dans un environnement de diffusion adaptative en continu. Un ou plusieurs canaux adjacents peuvent être définis pour un dispositif client par rapport à un canal actuel de diffusion en continu, le dispositif client étant configuré pour la pré-lecture de métadonnées et d'informations d'initialisation relatives aux canaux adjacents définis sur la base de la bande passante, des conditions, des conditions de tampon, etc. Lors d'un changement de canal, le dispositif client est apte à utiliser les données issues de la pré-lecture pour obtenir rapidement un contenu codé de média en vue de sa restitution.
