The present invention relates to a video decoding method, a video encoding method, and a method of transmitting data. The video decoding method includes: acquiring block division information of a current block having a tree-based division structure from a bitstream; performing block division on the current block by using the acquired block division information; and decoding a sub-block obtained from block division of a current block, in which the block division information includes at least one of first division information indicating whether to divide the block into four blocks and second division information indicating whether to divide the block into two blocks, the current block is divided into a luma component block and a chroma component block, and the chroma component block is divided into a chroma component block and a chroma component block. Parsing the block division information for the luma component block and the chroma component block, respectively, the sub-block decoding comprising: acquiring de
