Abstract:
1. A digital television receiver, comprising: a demodulator adapted to demodulating an input signal containing first service data multiplexed with second service data; a first forward error correction (FEC) decoder adapted to decode the demodulated signal for first forward error correction (FEC) in order to correct errors in the first and second service data that occurred during reception of the input signal; a demultiplexer adapted to demultiplex the first service data and the second service data from the FEC-decoded signal; and a second forward error correction (FEC) decoder adapted to reorder and decode the demultiplexed first service data for second forward error correction (FEC) in order to additionally correct errors in the first service data that occurred during the reception of the input signal.
