    摘要: A digital broadcast receiver is presented. The digital broadcast receiver includes a tuner for receiving a DTV signal, 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 turbo-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 turbo-decoded 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.

    摘要: A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction (FEC) and expanding the FEC-coded enhanced data. The packet generator generates first and second enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. The first enhanced data packet includes an adaptation field including the pre-processed enhanced data and second enhanced data packet includes a payload region including the pre-processed enhanced data. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction (FEC), and the trellis encoder performs trellis encoding on the RS-coded data packets.

    摘要: A digital broadcast transmitter and a method of processing a DTV signal in the digital broadcast transmitter are disclosed. The digital broadcast transmitter includes a pre-processor, a first multiplexer, a post-processor, and a second multiplexer. The pre-processor includes a first interleaver, a group formatter, and a packer formatter. The first interleaver interleaves symbols corresponding to mobile service data. The group formatter maps data corresponding to the interleaved symbols into at least one region of a data group and adds place holders for main service data and non-systematic RS parity data to the data group. The packet formatter removes the place holders for the main service data and the non-systematic RS parity data, and generates mobile service data packets having data in the data group in which the place holders for the main service data and the non-systematic RS parity data are removed.
