Abstract:
1. A digital broadcast receiver, the digital broadcast receiver comprising: a tuner for receiving a DTV signal, the DTV signal comprising: a known data detector for detecting position information of the known data sequences from the DTV signal; an equalizer for compensating a channel distortion of the DTV signal according to at least one of the detected position information of the known data sequences; a first decoder for decoding, via a block unit, mobile service data in the channel distortion compensated DTV signal; and a second decoder for generating a Reed-Solomon (RS) frame including the decoding mobile service data and for correcting at least one error of the generated RS frame by performing cyclic redundancy check (CRC) decoding and RS decoding on the generated RS frame.
