Title (EN) METHOD AND APPARATUS FOR TRANSCODING BETWEEN HYBRID VIDEO CODEC BITSTREAMS
(FR) PROCEDE ET APPAREIL PERMETTANT D'EFFECTUER UN TRANSCODAGE ENTRE DES TRAINS DE BITS CODES PAR DES CODECS VIDEO HYBRIDES
Abstract: front page image
(EN)A method and apparatus (fig. 1) performing transcoding between bitstreams coded by hybrid video codecs which uses fewer resources than decoding/decompressing the original bitstream (4 of fig. 2) and recoding/recompressing it to the second format (6, 7, 8 of fig. 2). According to a specific embodiment, the method can exploits the similarity of the standard video compression algorithms to, where possible, convert encoded parameters in the incoming bitstreams directly into encoded parameters which constitute compliant data for the outgoing bitstream.
(FR)L'invention concerne un procédé et un appareil permettant d'effectuer un transcodage entre des trains de bits codés par des codecs vidéo hybrides, qui utilise moins de ressources que le décodage/la décompression du train de bits initial et l'enregistrement/la recompression de ce train de bits au deuxième format. Selon un mode de réalisation spécifique, ledit procédé peut exploiter la similarité des algorithmes de compression vidéo standards afin, lorsque cela est possible, de convertir directement des paramètres codés dans les trains de bits entrants en paramètres codés qui constituent des données conformes pour le train de bits sortant.
