Abstract
A transform size determination module includes a transform size preprocessor configured to process residual data from a picture of the video data to evaluate a plurality of transform block sizes and to generate candidate transform size data that indicates a selected non-null proper subset of the plurality of transform block size. A final transform size determination processor generates final transform block size data that indicates a final transform block size, based on the candidate transform size data.
