<p>A start code detecting apparatus for detecting a start code which indicates the start position of each layer from the bit stream of a compressed image according to the MPEG-standard is provided. The start code detecting apparatus includes two registers (10, 12), a barrel shifter (14), a start code detector (16), a state machine (18), a code length generator (20) and an accumulator (22). Therefore, the start code detecting apparatus adopts the barrel shifter (14) and the start code detector (16), so that the start code designating the start position of each layer can be effectively detected from the compressed bit stream. <IMAGE></p> |
