Abstract  Abstract

FIELD: physics.SUBSTANCE: they perform binary arithmetic decoding of the first cell indicating whether the delta quantization parameter is significant, of other cells that follow after said first cell indicating the absolute value of the delta quantization parameter, and the character cell that follows the other mentioned cells, indicating whether delta-quantization parameter is positive or negative; generate a delta quantization parameter by converting from the binary form of the first said fell, other said cells and the character cell, and generate the restored quantization parameter by adding the predicted quantization parameter to the delta quantization parameter, wherein the binary arithmetic decoding is performed using the contexts for first said cell and other mentioned cells and without using the context for the character cell.EFFECT: decoding the image quantization parameter for the video decoding process based on context-adaptive binary arithmetic coding.2 cl, 15 dwg
