Abrégé
(EN)
A data stream format for transmission of data frames (108) between a computer and a video client via an interface, the data stream being a plurality of data frames (108) transmitted sequentially, each data frame comprising: a frame header (110); video data (112), the video data (112) following the frame header (110); and audio data (114), the audio data (114) following the video data (112).
(FR)
L'invention concerne un format de flux de données destiné à la transmission de trames de données entre un ordinateur et un abonné vidéo par l'intermédiaire d'une interface. Ledit flux de données est constitué par une pluralité de trames de données transmises séquentiellement, comportant chacune un en-tête de trame, des données vidéo suivant l'en-tête de trame, et des données audio suivant les données vidéo.
