Abstract
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.
