Abstract: Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.

Abstract: A method of decoding a bitstream is provided. The method determines a block unit of an image frame of the bitstream. The method determines an intra prediction mode index of the block unit, which corresponds to one of multiple wide-angle candidate modes, each having an angle parameter. The method determines reference samples neighboring the block unit and whether the determined intra prediction mode index is equal to one of predefined indices each corresponding to one of predefined wide-angle modes in the wide-angle candidate modes.
