Abstract  Abstract

A video quantization parameter decoder comprising: a prediction unit the prediction unit from the past reconstructed quantized parameter to generate the prediction quantization parameter and a quantization parameter decoding unit; the quantization parameter decoding unit for indicating poor quantification first binary bit parameter is significant other binary bit absolute value indicating the difference quantization parameter is positive or negative sign binary bit and indicating poor quantification parameter of the binary arithmetic decoding wherein the quantization parameter decoding unit does not use for the context of the symbol binary bit. using a first context of the first binary bit and for other binary bits different from the first context of the context to perform binary arithmetic decoding use condition and wherein the first value of the binary bit is 0 the difference value qualificat parameter is equal to 0 and is 1 for the first value of the binary bit the difference quantization parameter is significant.
