Abstract
(EN) There is included a method and apparatus comprising computer code configured to cause a processor or processors to perform obtaining video data, creating, based on the video data, a timed metadata track indicating a segment bandwidth and comprising information of a plurality of aligned segments of a media adaptation set such that duration information and size information of each of the aligned segments are included in at least one metadata sample, switching to one of a plurality of representations of the video data based on whether the timed metadata track indicates at least an overflow to an input buffer per each of the plurality of representations, and delivering the one of the plurality of representations to a client as a part of an event stream and based on at least one mode indicated in the event stream.
(FR) Sont divulgués un procédé et un appareil comprenant un code informatique configuré pour amener un processeur ou des processeurs à réaliser l'obtention de données vidéo, la création, sur la base des données vidéo, d'une piste de métadonnées synchronisées indiquant une bande passante de segment et comprenant des informations d'une pluralité de segments alignés d'un ensemble d'adaptation multimédia de sorte que des informations de durée et des informations de taille de chacun des segments alignés soient incluses dans au moins un échantillon de métadonnées, la commutation vers l'une d'une pluralité de représentations des données vidéo sur la base du fait que la piste de métadonnées synchronisées indique au moins un débordement vers un tampon d'entrée pour chacune de la pluralité de représentations, et la livraison de l'une de la pluralité de représentations à un client en tant que partie d'un flux d'évènement et sur la base de d'au moins un mode indiqué dans le flux d'évènement.
