Abstract
(EN)
An encoding/decoding method and device according to the present invention may: determine at least one among a plurality of inter prediction modes as the inter prediction mode of the current block; form an inter prediction candidate list on the basis of the determined inter prediction mode; perform motion compensation on the basis of one prediction candidate in the inter prediction candidate list, and generate a first prediction block of the current block; and correct the first prediction block by using a prescribed intra prediction mode.
