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 34):
A computer system comprising:\n memory configured to receive and store encoded data, from a bitstream, for a frame of video; and a video decoder, implemented using one or more processors and memory, configured to perform operations to decode the encoded data, wherein the operations include, for a current block of pixel values of a transform unit (TU) for a coding unit (CU) of the frame:\n determining that the TU is a leaf TU; \n based at least in part on the determination that the TU is a leaf TU, referencing a flag, in the bitstream, for the current block, the flag indicating whether or not an inverse transform is to be used during the decoding for the current block; \n inverse quantizing residual values for the current block; \n selectively performing an inverse transform on the inverse quantized residual values for the current block, thereby producing intra-frame prediction residual information, wherein the inverse transform is performed if the flag indicates the inverse transform is to be used during the decoding for the current block, and wherein the inverse transform is skipped if the flag indicates the inverse transform is not to be used during the decoding for the current block, the inverse quantized residual values being the intra-frame prediction residual information if the flag indicates the inverse transform is not to be used during the decoding for the current block; \n determining intra-frame prediction values for the current block; and \n combining the intra-frame prediction residual information and the intra-frame prediction values for the current block.
