ADAPTIVE QUANTIZATION FOR ENHANCEMENT LAYER VIDEO CODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195973 titled 'ADAPTIVE QUANTIZATION FOR ENHANCEMENT LAYER VIDEO CODING

The abstract discusses techniques and tools for encoding enhancement layer video with spatially varying quantization and quantization that varies between color channels. Encoding tools determine spatial and color channel quantization variations and signal quantization parameters in the encoded bit stream. Decoding tools predict and determine quantization parameters for macroblocks in the video, performing inverse quantization that can vary spatially and 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.
