ABSTRACT:
The predictive coder of the present invention is an apparatus for converting data into variable-length codes and outputting them, in which a differential data item is calculated from an input information data item and a predictive data item, a subsequent predictive data item is calculated using the quantized differential data item obtained by quantizing the differential data item, and coding is performed in such a manner that quantized differential data item indicating a data value having the maximum frequency of occurrence of quantized differential data items is coded as a code having a shortest length.
