Abstract: A method for decoding a video, according to the present invention, may comprise the steps of: generating an intra block copy (IBC) merge candidate list for a current block; selecting any one of IBC merge candidates included in the IBC merge candidate list; deriving a block vector of the current block on the basis of the selected IBC merge candidate; and obtaining a prediction sample of the current block on the basis of the block vector.

Abstract: An image decoding method according to the present invention may comprise the steps of: generating an affine mergence candidate list for a current block; specifying one of multiple affine mergence candidates contained in the affine mergence candidate list; deriving affine seed vectors of the specified mergence candidate; deriving a sub-block motion vector for a sub-block in the current block by using the affine seed vectors, wherein the sub-block is smaller in size than the current block; deriving offset data for the sub-block; and generating a sub-prediction block for the sub-block on the basis of the affine vector and the offset data.

Abstract: A method for decoding a video, according to the present invention, may comprise the steps of: parsing a first flag indicating whether inter prediction on the basis of a merge mode is applied to a current block; if the first flag is true, parsing a second flag indicating whether a regular merge mode or a merge offset encoding mode is applied to the current block; and if the second flag is true, parsing a third flag indicating whether the merge offset encoding mode is applied to the current block.
