DIGITAL TELEVISION TRANSMITTER AND METHOD OF CODING DATA IN DIGITAL TELEVISION TRANSMITTER |
摘要 |
A digital television (DTV) transmitter and a method of coding data in the DTV transmitter method are disclosed. A pre-processes enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded enhanced data. A data formatter generates enhanced data packets including the pre-processed enhanced data and inserting known data to at least one of the enhanced data packets. A first multiplexer multiplexes main data packets with the enhanced data packets, and a data randomizer randomizes the multiplexed data packets. A Reed-Solomon (RS) encoder RS-codes the randomized data packets by adding first parity data, and a data interleaver interleaves the RS-coded data packets. A trellis encoder trellis-encodes the interleaved data packets, wherein the trellis encoder may be initialized when a known data sequence is inputted thereto.
