Abstract: 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.

Abstract: A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. Herein, the transmitting system includes an RS frame encoder, a block processor, a group formatter, and a trellis encoding module. The RS frame encoder performs error correction encoding on an RS frame payload including mobile service data so as to form an RS frame, divides the RS frame into a plurality of portions, and outputs the divided RS frame portions. The block processor performs one of ½-rate encoding and ¼-rate encoding on each bit of the mobile service data included in each portion. The group formatter maps a portion including symbols of the ¼-rate encoded mobile service data and symbols of the ½-rate encoded mobile service data to a corresponding region of a data group. And, the trellis encoding module performs trellis encoding on the symbols of the ¼-rate encoded mobile service data and the symbols of the ½-rate encoded mobile service data of the data group.

Abstract: A DTV transmitting system includes an encoder, a randomizer, a block processor, a group formatter, a deinterleaver, and a packet formatter. The encoder codes enhanced data for error correction, permutes the coded data, and further codes the permuted data for error detection. The randomizer randomizes the coded enhanced data, and the block processor codes the randomized data at an effective coding rate of 1/H. The group formatter forms a group of enhanced data having data regions, and inserts the coded enhanced data into at least one of the data regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into corresponding data bytes.
