Abstract
An apparatus for video decoding includes receiving and processing circuitry. The circuitry is configured to receive a bitstream including a syntax element associated with a parent coding unit (CU) in a picture indicating the parent CU is partitioned into a predefined set of child CUs without performing a recursive tree-structure-based partitioning, and process the child CUs according to the indication of the syntax element to reconstruct the picture. In an embodiment, at least two subdivisions need to be performed when the parent CU is partitioned using the recursive tree-structure-based partitioning in order to obtain the same set of child CUs. In an embodiment, at least one of the child CUs has a size larger than a minimum allowed CU size for partitioning the parent CU and includes no syntax element to indicate whether the at least one of the child CUs is to be further subdivided.
