<p>PCT No. PCT/KR97/00082 Sec. 371 Date Apr. 10, 1998 Sec. 102(e) Date Apr. 10, 1998 PCT Filed May 13, 1997 PCT Pub. No. WO97/43861 PCT Pub. Date Nov. 20, 1997A decoding apparatus decodes symbols and header data obtained by variable length decoding. The decoding apparatus comprises a data distributor (10) for receiving the 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 and outputs parameters relating to restoration of the symbols. DC component decoding unit (40) detects symbols relating to DC coefficients of an intra-macroblock among the symbols output from the data distributor (10), and restores the DC coefficients of the intra-macroblock using the detected symbols and the parameters supplied from the header analyzer (50). First and second restoring units (20 and 30) which are individually connected to two output terminals of said data distributor (10) restore the symbols input from the data distributor (10) in units of a block, using the parameters generated by said header analyzer (50) and a corresponding DC coefficient of the DC coefficients produced by said DC component decoding unit (40).</p> |
