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 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: An image decoding method according to the present invention comprises the steps of: referring to a first flag for indicating whether intra block-based delta pulse code modulation (BDPCM) signaled through a sequence parameter set is permitted, so as to determine whether a second flag for indicating whether the intra BDPCM is applied to a current block is parsed; determining whether the intra BDPCM is applied to the current block on the basis of the second flag; determining an intra BDPCM mode of the current block when it is determined that the intra BDPCM is applied to the current block; and acquiring a residual sample of the current block on the basis of the intra BDPCM mode.
