Abstract
Cette divulgation concerne des procédés et des systèmes permettant de fournir des systèmes permettant de définir des valeurs permises du vecteur de mouvement différentiel (VMD) lors de la mise en place d'une résolution adaptative pour le vecteur de mouvement différentiel. Le procédé peut comprendre la réception du flux vidéo et le fait d'établir que le bloc vidéo actuel est intercodé, en fonction d'un bloc de prédiction et d'un vecteur de mouvement (VM). Par suite de l'établissement de la codification du VMD avec une résolution de VMD ayant une grande capacité d'adaptation, le procédé comprend également l'établissement d'une précision de pixel de VMD de référence pour le bloc vidéo actuel, le ciblage d'une précision de pixel maximum permise pour le VMD, l'établissement d'|| 'un ensemble de niveaux de VMD permise pour le bloc vidéo actuel (en fonction de la précision de pixel de référence du VMD), et la définition du VMD du flux vidéo (en fonction d'au moins un paramètre de VMD signalé dans le flux vidéo du bloc vidéo actuel et l'ensemble de niveaux de VMD disponibles).
