Abstract
(EN)
A method and apparatus include including, in a moving pictures experts group (MPEG) dynamic adaptive streaming over hypertext transfer protocol (DASH) media presentation description (MPD) file, an initialization presentation element that identifies an initialization presentation and one or more initialization groups included in the initialization presentation. An initialization group element that identifies an initialization group and one or more initialization sets included in the initialization group is included in the MPD file. An initialization set element that identifies an initialization set is included in the MPD file. The MPD file is transmitted to a client device.

La présente invention concerne un procédé et un appareil comprenant l'inclusion, dans un fichier de description de présentation multimédia (MPD) de la diffusion en continu adaptative dynamique sur le protocole HTTP (DASH) de groupe d'experts d'images animées (MPEG), d'un élément de présentation d'initialisation, lequel identifie une présentation d'initialisation et au moins un groupe d'initialisation inclus dans la présentation d'initialisation. Un élément de groupe d'initialisation, lequel identifie un groupe d'initialisation et au moins un ensemble d'initialisation inclus dans le groupe d'initialisation, est inclus dans le fichier MPD. Un élément d'ensemble d'initialisation, lequel identifie un ensemble d'initialisation, est inclus dans le fichier MPD. Le fichier MPD est transmis à un dispositif client.
