    摘要： A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction and expanding the FEC-coded enhanced data. The packet generator generates enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. Each enhanced data packet includes an adaptation field in which the pre-processed enhanced data are inserted. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction, and the trellis encoder performs trellis encoding on the RS-coded data packets.

    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.

    摘要： A digital television (DTV) receiving system includes a tuner, a demodulator, a known data detector, an equalizer, a transmission detector, and a block decoder. The tuner receives a DTV signal having a data frame in which main and mobile service data are multiplexed. The demodulator demodulates the DTV signal, and the known data detector detects known data included in the mobile service data. The equalizer equalizes the demodulated DTV signal using the detected known data, and the transmission parameter detector detects an error correction mode from the equalized DTV signal. Finally, the block decoder decodes the equalized DTV signal for error correction using the detected error correction mode.
