ABSTRACT:
A DTV transmitter includes a pre-processor pre-processing enhanced data, a data formatter generating enhanced data packets including the pre-processed data and inserting known data place holders to the data packets, and a multiplexer multiplexing the enhanced data packets with main data packets. It further includes an RS encoder which RS-codes the multiplexed data packets, and a data interleaves which interleaves the RS-coded data packets. The RS encoder adds systematic RS parity data to each main data packet and adds non-systematic RS parity place holders to each enhanced data packet. The RS encoder adds the RS parity place holders such that the RS parity place holders are placed after the enhanced data within each interleaved enhanced data packet.
