Abstract
(EN)
A video coding method and device, according to the present invention, determine whether motion compensation is performed by sub-block unit, determine a search area for motion compensation of a current block, calculate a plurality of SAD candidates with respect to the search area, derive delta motion information of the current block on the basis of the plurality of SAD candidates, and can compensate for motion information of the current block by using pre-generated motion information and the delta motion information of the current block.
(FR)
L'invention concerne un procédé et un dispositif de codage vidéo déterminant si une compensation de mouvement est effectuée par une unité de sous-bloc, déterminant une zone de recherche pour la compensation de mouvement d'un bloc actuel, calculant une pluralité de SAD candidates par rapport à la zone de recherche, déduisant des informations de mouvement delta du bloc actuel sur la base de la pluralité de SAD candidates, et pouvant compenser des informations de mouvement du bloc actuel en utilisant des informations de mouvement pré-générées et les informations de mouvement delta du bloc actuel.
