Abstract  Abstract

The image quantization parameter decoder includes prediction means for generating a predictive quantization parameter from a past reconstructed quantization parameter; A first bin indicating whether or not the differential quantization parameter is significant, a sign bin indicating positive quantization of the differential quantization parameter, and quantization parameter decoding means for performing binary arithmetic decoding on other bins indicating the absolute value of the differential quantization parameter; An inverse binarization unit for inversely binarizing the first bin, the other bin, and the sign bin to generate a differential quantization parameter; And adding means for adding a predictive quantization parameter to the difference quantization parameter to generate a reconstructed quantization parameter, wherein the quantization parameter decoding means uses the first context for the first bin without using the context for the sign bin , And performs binary arithmetic decoding on the other bins using the second context.
