Abstract
(EN) The method of encoding includes: determining an encoding mode indicating a current data unit for encoding of a picture and an encoding method including prediction encoding performed for the current data unit; determining an occurrence of merging with at least one neighboring data unit based on at least one of the encoding mode and a prediction mode; and determining prediction mode information, merging related information, and prediction related information, and determining encoding information of the data unit including the prediction mode information, the merging related information, and the prediction related information.
(FR) Le procédé d'encodage consiste à : déterminer un mode d'encodage indiquant une unité de données actuelle pour l'encodage d'une image et un procédé d'encodage effectué pour l'unité de données actuelle ; déterminer une occurrence de fusion avec au moins une unité de données voisine sur la base d'au moins l'un d'un mode d'encodage et d'un mode de prédiction ; et déterminer des informations de mode de prédiction, des informations associées à la fusion et des informations associées à la prédiction, et déterminer des informations d'encodage de l'unité de données comprenant les informations de mode de prédiction, les informations associées à la fusion et les informations associées à la prédiction.
