    摘要: A DTV transmitting system includes a first pre-processor for coding first enhanced data having a high priority for forward error correction (FEC) at a first coding rate and expanding the first enhanced data at a first expansion rate, and a second pre-processor for coding second enhanced data having a low priority for FEC at a second coding rate and expanding the second enhanced data at a second expansion rate. The receiving system further includes a data formatter for generating enhanced data packets, a multiplexer for multiplexing the enhanced data packets with main data packets, an RS encoder for RS-coding the multiplexed data packets, and a data interleaver for interleaving the RS-coded data packets and outputting a group of interleaved data packets having a head, a body, and a tail.

    摘要: A DTV transmitter includes a pre-processor expanding original enhanced data, a data formatter generating enhanced data packets including the expanded enhanced data and inserting known data place holders into the data packets, a multiplexer multiplexing the enhanced data packets with main data packets including main data, and an RS encoder adding systematic RS parity data to each main data packet and adding non-systematic RS parity data holders to each enhanced data packet. It further includes a data interleaver interleaving the RS-coded data packets, a known data generator generating know data symbols, a converter converting the interleaved data packet into symbols, and a symbol processor processing the converted symbols. The symbol processor removes symbols representing the null data, encodes symbols representing the original enhanced data at a rate of N/M, and replaces symbols representing the know data place holders with known data symbols.
