    摘要： A digital television receiving system includes a first known data detector, a second known data detector, and a selector. The first known data detector detects a location of a first known data sequence in a broadcast signal by calculating a first correlation value between the broadcast signal and a first reference known data sequence. Similarly, the second known data detector detects a location of a second known data sequence in the broadcast signal by calculating a second correlation value between the broadcast signal and a second reference known data sequence. The selector selects the location information detected by one of the first and second known data detectors with a greater correlation value.

    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.

    摘要： A DTV transmitter includes a signal generator, an interleaver, a trellis encoder, and a modulator. The signal generator generates a first data group including first, second and third regions, the first and third regions including main data and RS parity data, the second region including enhanced data coded with a first coding rate, enhanced data coded with a second coding rate, a plurality of known data sequences, signaling information and RS parity data. The interleaver interleaves the first data group to generate a second data group including fourth, fifth and sixth regions, the fifth region including enhanced data, a plurality of known data sequences, signaling information, and RS parity data, the fourth region including main data, RS parity data, and enhanced data. The trellis encoder trellis-encodes the second data group. The modulator modulates a broadcast signal including the trellis encoded second data group.

    摘要： A service multiplexer of a digital broadcasting system includes a null data generator, a mobile service multiplexer, a main service multiplexer, and a multiplexer. The null data generator may generate null data. The mobile service multiplexer may multiplex and output compression encoded mobile service data, additional data for a mobile service, and null data at a pre-determined first data rate. The main service multiplexer may multiplex and output compression encoded main service data and additional data for a main service at a pre-determined second data rate. The multiplexer may multiplex the output data of the main service multiplexer and the output data of the mobile service multiplexer at a pre-determined third data rate and transmitting the multiplexed data to at least one transmitter located at a remote position.
