Abstract

L'invention concerne des codecs vidéo échelonnables destinés à être utilisés dans des systèmes et des applications de vidéoconférence hébergés sur des points d'extrémité/récepteurs hétérogènes et des environnements de réseau. Les codecs vidéo échelonnables fournissent une représentation codée d'un signal vidéo source à des résolutions temporelles, de qualité et spatiales multiples.
