摘要： A digital television (DTV) transmitter/receiver and a method of processing data in the DTV transmitter/receiver are disclosed. In the DTV transmitter, a pre-processor pre-processes the 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 inserts known data to at least one of the enhanced data packets. A first multiplexer multiplexes the enhanced data packets with main data packets including the main data. And, an RS encoder RS-codes the multiplexed main and enhanced data packets, the RS encoder adding systematic parity data to each main data packet and adding RS parity place holders to each enhanced data packet. Herein, the RS encoder may insert non-systematic RS parity data or null data into the RS parity place holders included in each enhanced data packet.

摘要： A pre-processor pre-processes enhanced data packets by coding the enhanced data packets for forward error correction (FEC) and expanding the FEC-coded data packets. A data formatter adds first null data into first place holders within each pre-processed enhanced data packet. A first multiplexer multiplexes the main data packets with the enhanced data packets having the first null data. A holder inserter inserts second null data into second place holders within an enhanced data packet outputted from the first multiplexer. A data interleaver replaces the second null data with parity data. A data generator generates at least one known data sequence. A symbol processor replaces the first null data included in an output of the data interleaver with the known data sequence(s). A non-systematic RS encoder generates the parity data by performing non-systematic RS-coding on an output of the symbol processor, and provides the parity data to the data interleaver.
