Abstract

L'invention se rapporte à un Procédé de diffusion de données audio et vidéo par un dispositif serveur. Un réseau (2) peut connecter entre eux différents éléments média d'un même foyer. Un tel réseau comporte un serveur (1), généralement un ordinateur, et des clients (3), par exemple un décodeur. Cette configuration offre la possibilité de créer un bureau géré par le serveur (1) mais commandé à distance par le client (3) via le réseau (2). Un tel réseau (2) doit faire circuler des données et les traiter rapidement. Actuellement, la tendance est de compresser au maximum les données transitant sur le réseau (2). Cependant plus ces données sont compressées plus elles sont longues a traiter. L'invention prévoit non pas de faciliter le transfert des données mais au contraire de réduire le temps de traitement des données circulant sur le réseau (2) en envoyant seulement la première et la dernière image d'une séquence d'animation graphique.
