ABSTRACT:
An error correction apparatus and an error correction method according to the present invention can reduce an entire lead-in time of a demodulation system by reducing a lead-in time for deinterleave mode judgement, which greatly affects the entire lead-in time of the demodulation system. This error correction apparatus employs an output signal (perror) from a Reed-Solomon decoding unit that is connected outside of a deinterleave unit, as a trigger for changing deinterleave modes (dimode).
