Abstract  Abstract

The invention claims an image decoder quantization parameter a quantization parameter decoding device the quantization parameter decoding unit by indicating poor quantization parameter whether a meaning of the first binary bit. other binary bits indicating absolute value of the difference quantization parameter and indicating the difference quantization parameter is positive or negative sign binary bit by binary arithmetic decoding to decode the other binary bit after the first binary bit the symbol binary bit after the other binary bit; de-binarization device used by the first binary bit the other binary bits and the symbol binary bit binarization to generate a difference quantization parameter and adding device; used to generate the quantization parameter reconstruction by adding prediction to the difference quantization parameter of the quantization parameter wherein the binary arithmetic decoding is used for the first binary bit and the other binary bits unused for the context and the context of the signed binary bit is performed.
