Abstract:
1. A method of processing digital broadcast data in a digital television (DTV) receiver, the method comprising: demodulating a DTV signal in a demodulator, the DTV signal containing first service data multiplexed with second service data; detecting signaling information from the demodulated DTV signal in a detector; decoding the first service data in the demodulated DTV signal in a first decoder for first error correction by using a first error correction function in order to correct errors in the first service data that occurred during reception of the DTV signal; and decoding the error-corrected first service data in a second decoder for second error correction by using a second error correction function in order to additionally correct errors in the first service data that occurred during reception of the DTV signal, wherein the first and second error correction functions are different from each other.
