Abstract
(EN)
Disclosed are a method for processing a video signal and a device therefor. Specifically, a method of processing a video signal on the basis of inter-prediction may comprise the steps of: compiling a mergence list on the basis of blocks neighboring to a current block; adding, to the mergence list, a history-based mergence candidate indicating motion information of a block coded before the current block; acquiring a mergence index indicating, of the mergence list, a mergence candidate to be used in inter-prediction for the current block; generating a prediction block for the current block on the basis of motion information of the mergence candidate indicated by the mergence index; and reconstructing the current block by adding, to the prediction block, the residual block corresponding to the current block, wherein the history-based mergence candidate is added to the mergence list if the motion information of the history-based mergence candidate is not the same as that of a predetermined mergence candidate among the mergence candidates included in the mergence list.

La présente invention concerne un procédé de décodage d’un signal vidéo et un dispositif afférent. Spécifiquement, un procédé de traitement d'un signal vidéo sur la base d'une inter-prédiction peut comprendre les étapes consistant à : compiler une liste de fusion sur la base de blocs voisins d'un bloc courant; ajouter, à la liste de fusion, un candidat de fusion sur la base d'un historique indiquant des informations de mouvement d'un bloc codé avant le bloc courant; acquérir un indice de fusion indiquant, dans la liste de fusion, un candidat de fusion à utiliser en inter-prédiction pour le bloc courant; générer un bloc de prédiction pour le bloc courant sur la base d'informations de mouvement du candidat de fusion indiqué par l'indice de fusion; et reconstruire le bloc courant par ajout, au bloc de prédiction, du bloc résiduel correspondant au bloc courant, le candidat de fusion basé sur l'historique étant ajouté à la liste de fusion si les informations de mouvement du candidat de fusion basé sur l'historique ne sont pas identiques à celles d'un candidat de fusion prédéterminé parmi les candidats de fusion inclus dans la liste de fusion.
