1. A video decoding method comprising:
obtaining split information indicating whether a current block is to be split into lower blocks from a bitstream;
when a smaller value among a height and a width of the current block is smaller than a minimum SUCO size or a larger value among the height and the width of the current block is greater than a maximum SUCO size, determining lower horizontal coding order information applied to the lower blocks to be identical to higher horizontal coding order information applied to the current block, without obtaining the lower horizontal coding order information from the bitstream;
splitting the current block into the lower blocks when the split information indicates that the current block is to be split; and
decoding the lower blocks according to a coding order indicated by the lower horizontal coding order information,
wherein the lower blocks are two lower blocks determined by splitting the width of the current block or the height of the current block, three lower blocks determined by splitting the width of the current block or the height of the current block, or four lower blocks determined by splitting the height and the width of the current block.
