Abstract:
Techniques for selectively transforming one or more coding units when coding video content are described herein. The techniques may include determining whether or not to transform a particular coding unit. The determination may be based on a difference in pixel values of the particular coding unit and/or one or more predefined rate-distortion constraints. When it is determined to not perform a transform, the particular coding unit may be coded without transforming the particular coding unit.

Claim (Index 28):
In a computing device that implements a video encoder, a method of encoding video, thereby producing encoded data in a bitstream, wherein the method includes, for a current block of pixel values of a transform unit (TU) for a coding unit (CU) of a frame of the video:\n determining intra-frame prediction values for the current block; based at least in part on the intra-frame prediction values, determining intra-frame prediction residual information for the current block; selectively performing a transform on the intra-frame prediction residual information for the current block, thereby producing residual values for the current block, the residual values being the intra-frame prediction residual information if the transform is not performed for the current block, and the residual values being transform coefficients if the transform is performed for the current block; quantizing the residual values for the current block; determining that the TU is a leaf TU; and based at least in part on the determination that the TU is a leaf TU, setting a flag, in the bitstream, for the current block, the flag indicating whether or not an inverse transform is to be used during decoding for the current block, wherein the inverse transform is to be skipped if the flag indicates the inverse transform is not to be used during the decoding for the current block.
