Abstract  Abstract

FIELD: physics.SUBSTANCE: method of encoding a video quantization parameter is disclosed for encoding a quantization parameter for a video encoding process that is based on context-adaptive binary arithmetic coding, the method of encoding the video quantization parameter is that: the predicted quantization parameter is generated from a previous restored quantization parameter; generate the delta quantization parameter from the quantization parameter and the predicted quantization parameter; and performing binary arithmetic coding of the first cell indicating whether the delta quantization parameter is significant, the sign cells indicating whether the delta quantization parameter is positive or negative, and other cells indicating the absolute value of the delta quantization parameter in the case where the delta quantization parameter is significant, the binary arithmetic coding is performed without using the context for the sign cell using the first context for the first cell and using a context other than the first context for the other cells.EFFECT: encoding the video quantization parameter for video encoding and decoding the video quantization parameter for video decoding that use context-adaptive binary arithmetic coding.6 cl, 16 dwg
