    Abstract: An image decoding method according to the present document comprises a step for performing inverse first-order transform and inverse non-separable transform on a residual sample. The inverse non-separable transform is performed on the basis of a transform index indicating a predetermined transform kernel matrix, the inverse first-order transform is performed on the basis of a multiple transform selection (MTS) index indicating MTS for a horizontal transform kernel and a vertical transform kernel, and a syntax element bin string for the transform index is derived on the basis of first context information when a tree type for a split structure of a target block is not a single tree type and is derived on the basis of second context information when the tree type is the single tree type.

    Abstract: Disclosed is a video decoding method performed by a decoding device. The method comprises obtaining first split information for a first target block from a bitstream and, based on the first split information representing that the first target block is split, splitting the first target block to first sub blocks. The method also comprises obtaining Multiple Partitioning Tree (MPT) split information for a second target block from the bitstream, wherein the second target block is one of the first sub-blocks of the first target block. The method also comprises splitting the second target block to second sub-blocks based on the MPT split information and decoding the second sub-blocks. The second sub-blocks are non-square blocks and the MPT split information includes a MPT split flag for the second target block. The MPT split flag informs whether the second target block is split to the second sub-blocks that are the non-square blocks and, based on a value of the MPT split flag being equal to 1, the MPT split information includes MPT split type information and MPT split direction information for the second target block. The MPT split direction information informs a split direction of the second target block and the MPT split type information informs a number of the second sub-blocks to which the second target block is split. Further, based on a size of the second target block being 2Nx2N and the number of the second sub-blocks informed by the MPT split type information being equal to 3 and the split direction of the second target block informed by the MPT split direction information being a vertical direction, the second target block is split to an Nx2N size second sub-block and N/2x2N size second sub-blocks. Further, based on a size of the second target block being 2Nx2N and the number of the second sub-blocks informed by the MPT split type information being equal to 3 and the split direction of the second target block informed by the MPT split direction information being a horizontal direction, the second target block is split to a 2NxN size second sub-block and 2NxN/2 size second sub-blocks. The information on MPT structure is obtained through a Sequence Parameter Set (SPS) and the information on the MPT structure includes information on maximum depth in the MPT structure for an intra slice, information on maximum block size in the MPT structure for the intra slice, information on maximum depth in the MPT structure for an inter slice and information on maximum block size in the MPT structure for the inter slice. Additionally, the maximum depth in the MPT structure for the intra slice, the maximum block size in the MPT structure for the intra slice, the maximum depth in the MPT structure for the inter slice, the maximum block size in the MPT structure for the inter slice are derived based on the information on the MPT structure, and a process of the splitting the second target block to the second sub-blocks is performed based on the maximum depth in the MPT structure for the intra slice, the maximum block size in the MPT structure for the intra slice, the maximum depth in the MPT structure for the inter slice, the maximum block size in the MPT structure for the inter slice.
