Abstract

La présente invention permet de distribuer sur un réseau un seul fichier vidéo ou audio codé qui peut être lu par différents clients avec des débits binaires, des résolutions et des niveaux de qualité différents, déterminés individuellement par chaque client. Un codeur insère dans les trains de bits du fichier média des informations de « signalisation de couche » qui délimitent et identifient plusieurs couches différentes (par exemple, différentes « couches de signification/échelle » et différentes « couches de région »). Un serveur de média stocke les fichiers média et peut distribuer à différents clients sur le réseau des trains de bits aux propriétés différentes en fonction des couches demandées par chaque client ou convenant à chaque client.
