Title (EN) DYNAMIC CHUNK MANIPULATION FOR STREAMING MIXED LIVE AND ON-DEMAND MEDIA: APPLICATION PROGRAMMING INTERFACE
(FR) MANIPULATION DYNAMIQUE DE SEGMENTS POUR TRANSMISSION MULTIMÉDIA EN CONTINU MIXTE EN DIRECT ET À LA DEMANDE: INTERFACE DE PROGRAMMATION D'APPLICATION
Abstract:
(EN) Timestamps for streams of media that transition from one media source to another (such as from live content to on-demand content, and vice versa) can be rewritten by a server to help ensure error-free streaming by the client. Embodiments can coordinate the creation of a client manifest with the dynamic creation of a requested segment of media (i.e., "chunk") to determine how to rewrite timestamps of requested chunks such that they are continuous through the transition.
(FR) L'invention concerne des estampilles temporelles pour des flux de données multimédia qui effectuent une transition d'une source multimédia vers une autre (telle que d'un contenu en direct vers un contenu à la demande, et inversement) qui peuvent être réécrites par un serveur afin de garantir une transmission en continu sans erreur par le client. Des modes de réalisation de l'invention peuvent coordonner la création d'un manifeste client par la création dynamique d'un segment de média (c'est-à-dire un "chunk" en anglais) demandé, pour déterminer comment réécrire l'estampille temporelle des segments demandés de façon qu'ils soient continus pendant la transition.
