Abstract  Abstract

A video decoder quantization parameter comprising: a prediction device the prediction device for reconstruction from previous quantization parameter to generate the prediction quantization parameter a quantization parameter decoding device performing binary arithmetic decoding other binary bit absolute value quantization parameter decoding device for indicating poor quantization parameter whether a meaning of a first binary bit indicating poor quantization parameter is positive or negative sign binary bit and indicating the difference quantization parameter binarization device binarization device used for the first binary bit other binary bits and sign binary bit-binary to generate a difference quantization parameter and increasing device increasing device for difference quantification parameters to increase the prediction quantization parameter to generate the quantization parameter reconstruction is not used for context of signed binary bits using a first context of a first binary bit and second context for other binary bit for performing binary arithmetic decoding use wherein quantization parameter decoding device.
