1. A picture partitioning method for use in video coding, comprising:
determining a split mode of a current node that comprises a luma block and a chroma block, and wherein the current node is a node in a coding tree;
determining that the chroma block of the current node is not split and becomes a coding unit including only a chroma block based on:
a data format of the current node, the data format of the current node being YUV4:2:0 or YUV4:2:2,
the split mode of the current node, and
a size of the current node; and
splitting the luma block of the current node based on the split mode of the current node to obtain child nodes of the current node, wherein each child node comprises only a luma block.
