ADAPTIVE QUANTIZATION FOR ENHANCEMENT LAYER VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18400662 titled 'ADAPTIVE QUANTIZATION FOR ENHANCEMENT LAYER VIDEO CODING
Simplified Explanation
The patent application describes techniques and tools for encoding enhancement layer video with spatially varying quantization and/or quantization that varies between color channels. The encoding tool determines the spatial and color channel variations in quantization and signals the quantization parameters for macroblocks in the encoded bit stream. The 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, performing inverse quantization that can vary spatially and/or between color channels.

Original Abstract Submitted
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.
