摘要：A decoding apparatus decodes symbols and header data obtained by variablelength decoding. The decoding apparatus comprises a data distributor (10) for receivingthe symbols and alternately outputting blocks of the symbols via two output terminals.A header analyzer (50) receives the header data, analyzes the received header data andoutputs parameters relating to restoration of the symbols. DC component decoding unit(40) detects symbols relating to DC coefficients of an intra- macroblock among thesymbols output from the data distributor (10), and restores the DC coefficients of theintra-macroblock using the detected symbols and the parameters supplied from theheader analyzer (50). First and second restoring units (20 and 30) which are individuallyconnected to two output terminals of said data distributor (10) restore the symbolsinput from the data distributor (10) in units of a block, using the parameters generatedby said header analyzer (50) and a corresponding DC coefficient of the DC coefficientsproduced by said DC component decoding unit (40).
