Abstract  Abstract

A video quantization parameter coding device is provided with a prediction unit (11) for generating a prediction quantization parameter from a past reconstruction quantization parameter, a computation unit (12) for generating a differential quantization parameter from the quantization parameter and the prediction quantization parameter, and a quantization parameter coding means (13) for binary arithmetically coding a first bin indicating whether or not the differential quantization parameter is significant, a second bin indicating whether the differential quantization parameter is positive or negative, and another bin indicating the absolute value of the differential quantization parameter, if the differential quantization parameter is significant.
