Abrégé
(EN)
A method of and apparatus for updating decoding information are provided. A method of transmitting media data includes generating a media stream including one or more media data items, one or more decoding information of the media stream, and information for arranging updating of the decoding information; and transmitting the media stream, the one or more decoding information item of the media stream, and the information for arranging updating of the decoding information, in which the one or more media data items have decoding information that are different from each other. According to the method and apparatus, the amount of data to be processed and the complexity of data processing can be reduced, thereby reducing an encoding time and a media data processing time in a decoder.

L'invention concerne un procédé et un appareil de mise à jour de données de décodage. Selon l'invention, un procédé d'émission de données multimédia consiste à générer un flux multimédia contenant un ou plusieurs éléments de données multimédia, une ou plusieurs données de décodage du flux multimédia, et des données permettant la mise à jour des données de décodage, et à émettre le flux multimédia, l'élément ou les éléments de données de décodage du flux multimédia, et les données de mise à jour des informations de décodage. L'élément ou les éléments de données multimédia contiennent des informations de décodage différentes les unes des autres. Ce procédé et cet appareil permettent de réduire la quantité de données à traiter et la complexité du traitement de données, et de réduire ainsi le temps de codage et le temps de traitement des données multimédia dans un décodeur.
