Abstract

A digital television (DTV) receiver comprises a demodulator configured to demodulate a DTV signal containing first service data multiplexed with second service data. A first decoder is configured to decode the demodulated DTV signal for first error correction, in order to correct errors in the first and second service data that occurred during reception of the DTV signal. A data separator is configured to separate the first service data and the second service data from the decoded DTV signal and a second decoder is configured to further decode the separated first service data for second error correction in order to additionally correct errors in the first service data that occurred during the reception of the DTV signal.
