Abstract

Une méthode et un système permettent le codage et le décodage de contenu vidéo numérique. Le contenu vidéo numérique comprend un flux de photos qui peuvent être des images internes, prédites ou biprédites. Chacune des images comprend des macroblocs qui peuvent subdivisés en blocs plus petits. La méthode comprend le codage et le décodage de chaque image dudit flux d'images en mode trame ou en mode champ.
