Abstract
(EN)
In one example, a device for retrieving video data includes one or more processors configured to receive data describing a sample entry type for a sample of a video bitstream, the sample entry type being one of 'hev1' or 'hev2', wherein the sample comprises video data encoded according to one of High-Efficiency Video Coding (HEVC) or layered HEVC (L-HEVC), and wherein one or more other samples including video data precede the sample in the video bitstream in decoding order, and in response to the sample entry type being 'hevl ' or 'hev2' and the sample comprising the video data encoded according to one of HEVC or L-HEVC, retrieve the sample to perform random access using the sample, without retrieving the video data of any of the one or more other samples that precede the sample, and without retrieving parameter sets of any previous samples of the video bitstream in decoding order.

Un exemple de l'invention concerne un dispositif de récupération de données vidéo comprenant un ou plusieurs processeurs configurés pour recevoir des données décrivant un type d'entrée d'échantillon pour un échantillon d'un flux binaire vidéo, le type d'entrée d'échantillon étant l'un parmi 'hev1' ou 'hev2'. L'échantillon comprend les données vidéo codées conformément soit au codage vidéo à haute efficacité (HEVC), soit au HEVC en couches (L-HEVC), et un ou plusieurs autres échantillons contenant des données vidéo précèdent l'échantillon dans le flux binaire vidéo dans l'ordre de décodage. En réponse au fait que le type d'entrée d'échantillon est 'hev1' ou 'hev2' et au fait que l'échantillon comprend les données vidéo codées conformément soit au HEVC, soit au L-HEVC, récupération de l'échantillon pour effectuer un accès aléatoire en utilisant l'échantillon, sans récupérer les données vidéo de l'un quelconque des un ou plusieurs autres échantillons qui précèdent l'échantillon, et sans récupérer des ensembles de paramètres de l'un quelconque des échantillons précédents du flux binaire vidéo dans l'ordre de décodage.
