Abstract

L'invention concerne un procédé et un appareil permettant de coder et décoder des signaux de télévision évolués au moyen de moteurs de compression MPEG-2 standards tout en maintenant l'efficacité de compression de ces moteurs de compression. L'architecture permet d'effectuer un traitement parallèle au moyen de moteurs de compression MPEG-2 standards dans un montage superposé n'altérant pas les performances de compression. Un codeur vidéo comprend plusieurs processeurs de zone destinés au codage d'un flux d'entrée d'images vidéo. Chaque image vidéo est divisée en zones comportant des parties superposées, chaque processeur codant une zone particulière d'une image vidéo courante dans le flux. Chaque processeur de zone mémorise une trame de référence dans une mémoire locale sur la base d'une image vidéo antérieure dans le flux afin de l'utiliser dans la compensation de mouvement du procédé de codage. Un processeur de trame de référence couplé aux multiples mémoires locales met à jour chaque trame de référence à l'aide d'informations provenant de trames de référence mémorisées dans les mémoires locales contiguës. Les images vidéo codées sont formées de macroblocs et chaque processeur de zone comprend un dispositif d'élimination de certains macroblocs des images vidéo codées correspondant aux parties superposées et de concaténation des images vidéo codées obtenues avec celles des autres processeurs de zone pour former un flux vidéo de sortie.
