Abstract  Abstract

A first bin indicating whether the difference quantization parameter is significant or not, other bins following the first bin and representing the absolute value of the difference quantization parameter, and a second bin following the other bins and indicating the absolute value of the difference quantization parameter A binarization means for binarizing-signing-decoding the sign bin representing the positive binarization, a binarization-canceling means for binarizing the first bin, the other binars, and the sign bin to generate a differential quantization parameter And an adding means for adding the predictive quantization parameter to the differential quantization parameter to generate a re-construction quantization parameter, wherein the binary-arithmetic-decoding means performs the binary-arithmetic-decoding on the sign bin without using the context, The image quantization parameter decoder is performed using contexts for bin and the other bin.
