Abstract: An image decoding method according to the present disclosure comprises the steps of: determining whether a picture is to be divided into multiple sub-pictures; when it is determined that the picture is to be divided into multiple sub-pictures, dividing the picture into multiple sub-pictures; and determining whether the multiple sub-pictures are independent of each other.

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.

Abstract: An image decoding method according to the present invention may comprise the steps of: generating a merge candidate list of a current block; selecting one merge candidate from merge candidates included in the merge candidate list; and performing motion compensation of the current block on the basis of motion information of the selected merge candidate.

Abstract: A video decoding method according to the present invention may comprise: a step for determining whether to divide a current block into a plurality of sub-blocks; a step for determining an intra prediction mode for the current block; and a step for performing intra prediction for each sub-block on the basis of the intra prediction mode, when the current block is divided into the plurality of sub-blocks.
