Abstract

La présente invention concerne des système et des procédés pour la vidéoconférence. Les systèmes utilisent des techniques de décodage vidéo échelonnable et un serveur de vidéoconférence de composition d'images (CSVCS) pour la composition de signaux vidéo d'entrée provenant des participants émetteurs à la conférence en un signal vidéo de sortie unique acheminé à un participant récepteur. Les serveur est configuré pour la composition d'images de signaux vidéo d'entrée sans décodage, rééchelonnage et recodage des signaux.
