Title (EN) METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT D'UN SIGNAL VIDÉO

Abstract:
(EN) A method for decoding an image according to the present invention may comprise: a step inducing spatial merge candidates of a current block; a step of creating a merge candidate list for the current block on the basis of the spatial merge candidates; a step of obtaining motion information of the current block on the basis of the merge candidate list; and a step of performing motion compensation on the current block by using the motion information. Here, if the current block is not in a predefined shape or is not equal to or greater than a predefined size, the spatial merge candidates of the current bock may be induced base on a block, including the current block, which is in the predefined shape or equal to or greater than the predefined size.
(FR) Un procédé de décodage d'une image selon la présente invention peut comprendre : une étape de détermination de candidats à la fusion spatiale d'un bloc actuel ; une étape de création d'une liste de candidats à la fusion pour le bloc actuel sur la base des candidats à la fusion spatiale ; une étape d'obtention d'informations de mouvement du bloc actuel sur la base de la liste de candidats à la fusion ; et une étape de mise en oeuvre d'une compensation de mouvement par rapport au bloc actuel à l'aide des informations de mouvement. Selon l'invention, si le bloc actuel n'est pas dans une forme prédéfinie ou n'est pas supérieur ou égal à une taille prédéfinie, les candidats à la fusion spatiale du bloc actuel peuvent être déterminés sur la base d'un bloc, contenant le bloc actuel, ayant la forme prédéterminée ou une taille supérieure ou égale à la taille prédéterminée.
(KO) 본 발명에 따른 영상 복호화 방법은, 현재 블록에 대한 공간적 머지 후보를 유도하는 단계, 상기 공간적 머지 후보를 기초로, 상기 현재 블록에 대한 머지 후보 리스트를 생성하는 단계, 상기 머지 후보 리스트를 기초로, 상기 현재 블록에 대한 움직임 정보를 획득하는 단계, 및 상기 움직임 정보를 이용하여, 상기 현재 블록에 대한 움직임 보상을 수행하는 단계를 포함할 수 있다. 이때, 상기 현재 블록이 기 정의된 형태 또는 기 정의된 크기 이상이 아닌 경우, 상기 현재 블록의 공간적 머지 후보는, 상기 현재 블록을 포함하는 기 정의된 형태 또는 기 정의된 크기 이상의 블록을 기준으로 유도될 수 있다.
