摘要：
A DTV receiver includes a tuner tuning to a channel to receive a broadcast signal, and a demodulator demodulating the broadcast signal. The receiver further includes a first decoder which decodes main and enhanced data included in the demodulated signal by calculating soft decision values for the enhanced data and hard decision values for the main data. The receiver further includes a second decoder for decoding the main and enhanced data for first forward error correction, and a third decoder for decoding the FEC-decoded enhanced data for second forward error correction.
