<p>An apparatus for decoding a video bitstream according to the MPEG standard. The decoder restores variable length decoded data at a processing speed required by high-speed systems, such as a high definition television system. The decoding apparatus includes a variable length decoder for variable length decoding the video bitstream and outputting header data and symbols obtained by the variable length decoding, a data distributor for receiving the output of the variable length decoder and alternately outputting the blocks of symbols via two output terminals, first and second restorers individually connected to the two output terminals of the data distributor for restoring the input symbols in response to an encoding indication signal for indicating whether each block is encoded, a header analyzer for receiving the header data form the variable length decoder and analyzing the received header data and outputting the encoding indication signal, and a macroblock formation unit for reconstructing blocks of the data restored by the first and second restorers into a macroblock.</p> |
