DTV transmitter and method of coding main and enhanced data in DTV transmitter










Image Number 17 for United States Patent #7797607.

A DTV transmitter includes a pre-processor pre-processing enhanced data, a data formatter generating enhanced data packets including the pre-processed enhanced data, and a multiplexer multiplexing the enhanced data packets with main data packets. The transmitter further includes an RS encoder RS-coding the multiplexed packets by adding systematic RS parity data to each main data packet and by adding non-systematic RS parity place holders to each enhanced data packet, and a data interleaver interleaving the RS-coded packets. The non-systematic RS parity place holders are placed after the enhanced data within each interleaved enhanced data packet, and a sequence of known data place holders is periodically included in the interleaved enhanced data packets.
