(FR) PROCESSUS ET SYNTAXE UNIFIÉS POUR UNE PRÉDICTION GÉNÉRALISÉE DANS UN CODAGE/DÉCODAGE VIDÉO
Abstract
(EN)
At least a method and an apparatus are provided for efficiently encoding or decoding video. For example, a plurality of different motion prediction modes are obtained for a current block. The current block is encoded or decoded based on a combination of the plurality of different motion prediction modes with corresponding weights, wherein the combination with the corresponding weights comprising at least two inter prediction modes, or an inter prediction mode and an intra prediction mode. Both triangle prediction and multi-hypothesis prediction are allowed to be indicated in one or more lists of possible motion vector candidates, such as, e.g., in advanced motion vector prediction (AMVP) mode.

La présente invention concerne au moins un procédé et un appareil permettant un codage ou un décodage vidéo efficace. Par exemple, une pluralité de différents modes de prédiction de mouvement sont obtenus pour un bloc actuel. Le bloc actuel est codé ou décodé sur la base d’une combinaison de la pluralité des différents modes de prédiction de mouvement avec des poids correspondants, la combinaison avec les poids correspondants comprenant au moins deux modes d’inter-prédiction, ou un mode d’inter-prédiction et un mode de prédiction intra. À la fois une prédiction triangulaire et une prédiction à multiples hypothèses peuvent être indiquées dans une ou plusieurs listes de candidats de vecteurs de mouvement possibles, tels que, par exemple, dans un mode de prédiction avancée de vecteur de mouvement (AMVP).
