Abstract  Abstract

An image quantization parameter decoding method for decoding a quantization parameter for a video decoding process based on context-based adaptive binary arithmetic coding, the image quantization parameter decoding method comprises: generating a quantization parameter expected from quantization parameter reconstructed in the past; decode with binary arithmetic a string of bins comprising: i) a first bin that indicates whether a delta quantization parameter is significant, ii) other bins, which are subsequent to the first bin, indicating an absolute value of the delta quantization parameter, and iii) a sign bin, which is later than the other bins, indicating whether the delta quantization parameter is positive or negative; generate the delta quantization parameter by unbinding the decoded binary chain with binary arithmetic; and generate a reconstructed quantization parameter by adding a predicted quantization parameter to the delta quantization parameter; in which the decoding with binary arithmetic is performed using context (s) for the first bin and the other bins, and not using context for the sign bin, and in which the decoding with binary arithmetic is performed until the predetermined number of the other bines are decoded in the case where the delta quantization parameter is significant.
