Abstract:
1. An error correction apparatus that performs error correction of received data according to a deinterleave mode inserted in the received data, comprising: a deinterleave unit for receiving a frame sync signal and a first Reed-Solomon packet head signal which are synchronized with received data, deinterleaving the received data, and outputting deinterleaved data and a second Reed-Solomon packet head signal that is synchronized with the deinterleaved data; a Reed-Solomon decoding unit for receiving the second Reed-Solomon packet head signal that is synchronized with the deinterleaved data, Reed-Solomon decoding the deinterleaved data, and outputting Reed-Solomon decoded data resulting from error correction as well as outputting a third Reed-Solomon packet head signal and a Reed-Solomon packet error signal which are synchronized with the Reed-Solomon decoded data; and a deinterleave mode generation unit for receiving the third Reed-Solomon packet head signal and the Reed-Solomon packet error signal as trigger signals for changing the deinterleave mode, and generating a changed deinterleave mode.
