Title (EN) SYSTEM AND METHOD FOR VIDEOCONFERENCING USING SCALABLE VIDEO CODING AND COMPOSITING SCALABLE VIDEO CONFERENCING SERVERS
(FR) SYSTEME ET PROCEDE POUR LA VIDEOCONFERENCE UTILISANT LE DECODAGE VIDEO ECHELONNABLE ET SERVEURS DE VIDEOCONFERENCE DE COMPOSITION D'IMAGES
Abstract: front page image
(EN)Systems and methods for videoconferencing are provided. The systems use scalable video coding techniques and a compositing scalable video coding server (CSVCS) to composite input video signals from transmitting conferencing participants into one single output video signal forwarded to a receiving participant. The server is configured to composite the input video signals pictures without decoding, rescaling, and re-encoding of the signals.
(FR)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.
