Abstract
Provided is a video decoding method performed by a decoding apparatus, which includes: obtaining split information for a target block from a bitstream; splitting the target block into a first sub-block and a second sub-block based on a split boundary indicated by the split information; deriving a first motion information candidate list for the first sub-block and a second motion information candidate list for the second sub-block based on the split information for the target block; performing inter prediction of the first sub-block based on the first motion information candidate list; and performing inter prediction of the second sub-block based on the second motion information candidate list, in which the first sub-block and the second sub-block are non-rectangular blocks, and the first motion information candidate list for the first sub-block is different from the second motion information candidate list for the second sub-block.
