A video processing system. In a specific embodiment, the system implements a system for processing macroblocks that includes a first module for processing a macroblock. A controller provides a first macroblock to the first module and provides a second macroblock to the first module, without waiting for the first module to complete processing of the first macroblock, when information is available to the first module to process the second macroblock. The first module may implement a pipelined processor that is adapted to process macroblocks simultaneously. Alternatively, the first module includes a first engine and a second engine, which may run in parallel as parallel engines. In a more specific embodiment, an entire image frame is treated as a single slice and processed by the system via a pipelined engines or parallel engines.

L'invention concerne un système de traitement vidéo. Dans un mode de réalisation spécifique, le système met en oeuvre un système de traitement de macroblocs qui comporte un premier module de traitement d'un macrobloc. Une unité de commande fournit un premier macrobloc au premier module et un second macrobloc au premier module, sans attendre que le premier module termine le traitement du premier macrobloc, lorsque ledit premier module dispose des informations pour le traitement du second macrobloc. Le premier module peut mettre en oeuvre un processeur pipeline conçu pour traiter les macroblocs simultanément. Autre variante, le premier module comporte un premier et un second moteur, qui peuvent fonctionner en parallèle comme moteurs parallèles. Dans un mode de réalisation plus spécifique, une trame d'image entière est considérée comme tranche simple et traitée par le système via des moteurs pipelines ou moteurs parallèles.
