1. A video decoding method, comprising:
decoding integrated code block information;
decoding a split information based on the integrated code block information and size information for a transform block; and
decoding code block information for the transform block in a case that the transform block is not additionally split based on the split information,
wherein:
the code block information is decoded based on the integrated code block information,
the code block information for the transform block comprises a luminance code block information for a luminance signal of the transform block, and
the code block information for the transform block comprises at least one of a first chrominance code block information for a first chrominance signal of the transform block and a second chrominance code block information for a second chrominance signal of the transform block.
