摘要:
A decoding apparatus includes a distribution generating section and a correcting section. The distribution generating section generates a frequency distribution of quantization index values. The correcting section corrects dequantization values corresponding to the quantization index values based on the frequency distribution of quantization index values generated by the distribution generating section.
