1. A decoding method, comprising:
performing a determination as to whether to perform decoding on three blocks using coding determination information shared for the three blocks; and
performing the decoding on the three blocks using the coding determination information based on the determination,
wherein the three blocks comprise a luma block and two chroma blocks, and
the coding determination information is applied to the three blocks as a single tree structure is used for the luma block and the two chroma blocks.
