Disclosed are a method for decoding or encoding a video and a method for transmitting a bitstream, in which the method for decoding a video comprises: determining whether to sub-block transform a current coding block on the basis of a sub-block transform flag, the sub-block transform flag indicating whether the sub-block transform is used for the current coding block, the sub-block transform flag indicating whether the sub-block transform is used for the current coding block, and the sub-block transform flag indicating whether the sub-block transform is used for the current coding block; the sub-block transformation refers to a transformation method for carrying out inverse transformation on a first sub-block in two sub-blocks in the current coding block and not carrying out inverse transformation on a second sub-block in the two sub-blocks; determining a partition type for the sub-block transform of the current coding block among a plurality of partition type candidates including a symmetric binary partition
