Abstract

PURPOSE: A variable-length coding and decoding devices using selective symbol/codeword realigning of code table are provided to improve data compression efficiency by using a code table that provides better coding efficiency. CONSTITUTION: A first storage unit(14) stores a pre-defined code table(T2). A realigning unit(13) generates a realigning data that identifies the relationship of the realigned code table(T1), symbols and codewords. A coder(100) codes the received symbols to the first and second codewords. The second storage unit stores the first codewords generated by the coder(100), the realigning data and the second codewords separately. A selective output unit(500) transmits an output that corresponds to a smaller one of the first or second data amount from the coder(100).
