Abstract

L'invention concerne des procédés, des logiciels et des systèmes servant à coder des données vidéo en un format plus comprimé et à décoder des données vidéo à partir du format comprimé. Ces procédés, logiciels et systèmes permettent d'effectuer un traitement préalable des données vidéo, de les coder en format comprimé au moyen d'une évaluation de mouvement global et local, de les transmettre, de les décoder, puis d'en effectuer un traitement postérieur.
