Abstract
(EN)
Disclosed are a video encoding and decoding method and a device. The method comprises: if the current block meets the specific condition for initiating the triangle prediction mode and it is determined to initiate the triangle prediction mode, dividing the current block into a first triangular sub-block and a second triangular sub-block; obtaining the first target movement information of the first triangular sub-block and the second target movement information of the second triangular sub-block, the first target movement information being different from the second target movement information; performing encoding or decoding on the current block according to the first target movement information and the second target movement information.
(FR)
L'invention concerne un procédé et un dispositif de codage et de décodage vidéo. Le procédé comprend les étapes suivantes : si le bloc courant satisfait la condition spécifique pour initier le mode de prédiction de triangle et qu'il est décidé pour initier le mode de prédiction de triangle, diviser le bloc courant en un premier sous-bloc triangulaire et un second sous-bloc triangulaire ; obtenir les premières informations de mouvement cible du premier sous-bloc triangulaire et les secondes informations de mouvement cible du second sous-bloc triangulaire, les premières informations de mouvement cible étant différentes des secondes informations de mouvement cible ; effectuer un codage ou un décodage sur le bloc courant d’après les premières informations de mouvement cible et les secondes informations de mouvement cible.
