Kodiereinrichtung

摘要

There is provided a coding device characterized in that when a difference value between a sample value and a predictive value is quantized into a coding code of n bits, in the case of quantizing by a quantization unit which can output (2 - 1) coding codes corresponding to positive quantization representative values, (2 - 1) coding codes corresponding to negative quantization representative values, and a coding code corresponding to the quantization representative value of the difference value 0, one remaining coding code is selectively made correspond to the positive and negative quantization representative values.
