Abstract

La présente divulgation concerne la signalisation d'un vecteur de mouvement ou d'une différence de vecteur de mouvement selon qu'une résolution de pixel de différence de vecteur de mouvement adaptative dépendant de l'amplitude est employée ou non dans un codage et un décodage vidéo. Un exemple de procédé de traitement d'un bloc vidéo d'un flux vidéo est divulgué. Le procédé peut consister à recevoir le flux vidéo ; à déterminer que le bloc vidéo est inter-codé sur la base d'un bloc de prédiction et d'un vecteur de mouvement (MV), le MV devant être dérivé d'un vecteur de mouvement de référence (RMV) et d'une différence de vecteur de mouvement (MVD) pour le bloc vidéo ; à extraire ou à dériver, à partir du flux vidéo, un élément de données associé au RMV et/ou à la MVD.
