Abstract
The application relates to an image encoding / decoding apparatus and an apparatus for transmitting data of image information. An image decoding method according to the present document comprises the steps of: decoding a current block on the basis of image information, in which an MVP candidate list of the current block is derived on the basis of an inter prediction mode derived on the basis of image information and peripheral blocks of the current block; and deriving motion information of the current block based on the MVP candidate list, in which the peripheral blocks include a lower left corner peripheral block, a left peripheral block, an upper right corner peripheral block, an upper peripheral block, and an upper left corner peripheral block of the current block, the motion information including an L0 motion vector for L0 prediction and / or an L1 motion vector for L1 prediction, the L0 motion vector is derived based on the L0 motion vector predictor and the L0 motion vector difference, and the L1 motion vector is derived based on the L1 motion vector predictor and the L1 motion vector difference.
