Title
(EN) A ROBUST, RELIABLE COMPRESSION AND PACKETIZATION SCHEME FOR TRANSMITTING VIDEO
(FR) SCHEMA DE CODAGE DE COMPRESSION ET DE MISE EN PAQUETS ROBUSTE, FIABLE, UTILE POUR LA TRANSMISSION DE VIDEOS
Abstract
(EN) For transmitting digital video information over a network such as the Internet, a hybrid coding scheme (Figs. 9-18) with wavelet I frame coding and H.263 predictive coding produces a robust, low bit rate video coding scheme. A new packetization method analyzes macroblock level dependency structure (Fig. 19) and packetizes the bit stream so as to minimize dependencies between packets and thereby minimize packet loss damage.
(FR) L'invention concerne un schéma de codage (fig. 9-18) hybride servant à transmettre des informations vidéo numériques sur un réseau tel que l'Internet à l'aide d'un codage de trames I par ondelettes et d'un codage prédictif de type H.263, qui constitue un schéma de codage vidéo robuste à faible débit binaire. Un nouveau procédé de mise en paquets permet d'analyser la structure (fig. 19) de dépendance de niveaux de macroblocs, et de mettre en paquets le train de bits de façon à réduire au minimum les dépendances entre paquets, ce qui permet de réduire au minimum des pertes de paquets.
