EFFICIENT TRANSFORM UNIT REPRESENTATION

摘要

In one embodiment, a method includes receiving a prediction unit (PU) for a coding unit (CU) of the video content. The method analyzes the prediction unit to determine a size of prediction unit. A size of a transform unit is determined based on the size of the prediction unit based on a set of rules. The set of rules specify the size of the transform unit is linked to the size of prediction unit and not a size of the coding unit. The method then outputs the size of the transform unit for use in a transform operation.
