ABSTRACT:
An apparatus for expanding variable-length codes includes a decoder responsive to compressed data, into which quantized data is compressed on the basis of coding table data, for expanding the compressed data on the basis of decoding table data for variable-length codes to produce symbol data. The apparatus further includes a storage in which the decoding table data for variable-length codes is rewritably stored and a table schemer for generating the decoding table data, from the coding table data, to store the decoding table data thus generated into the storage. The decoder is adapted to consult with the decoding table data stored in the storage to expand the compressed data. The apparatus may be provided with an encoder responsive to the quantized data for compressing the quantized data on the basis of the coding table data to produce compressed data associated with the quantized data.
