Abstract: A video coder determines a coding unit (CU) is partitioned into transform units (TUs) of the CU based on a tree structure. As part of determining the CU is partitioned into the TUs of the CU based on the tree structure, the video coder determines that a node in the tree structure has exactly two child nodes in the tree structure. A root node of the tree structure corresponds to a coding block of the CU, each respective non-root node of the tree structure corresponds to a respective block that is a partition of a block that corresponds to a parent node of the respective non-root node, and leaf nodes of the tree structure correspond to the TUs of the CU.
