摘要： A DTV receiver includes a tuner, a demodulator, a channel equalizer, a sequence detector, and a burst controller. The tuner receives a DTV signal having main data and at least one burst of enhanced data. The demodulator demodulates the DTV signal by performing carrier and time recovery and the channel equalizer equalizes the demodulated signal. The sequence detector detects one or more known data sequences from any one of the received signal and the demodulated signal. The demodulator and the channel equalizer use the detected known data sequences when performing the carrier and timing recover and the channel-equalization, respectively. Lastly, the burst controller supplies power to the tuner, the demodulator, the channel equalizer, and the data detector only during a burst time for each burst of enhanced data for efficient power consumption.

摘要： A digital television transmitter and a method of coding main and enhanced data in the digital television transmitter are disclosed. In the digital television transmitter, a byte-symbol converter converts main and enhanced data packets into symbols, wherein at least one of the enhanced data packets may include data place holders for known data symbols. A known data generator generates a known data symbol. A symbol processor processes a first symbol outputted from the byte-symbol converter. Herein, the symbol processor may post-decode a first bit of the known data symbol and output the post-decoded bit and an initialization data bit when the first symbol is a symbol representing one of the place holders. A trellis encoder has one or more memories for trellis-encoding a second symbol outputted from the symbol processor, wherein the memories are initialized when the initialization data bit is processed in the trellis encoder.

摘要： A pre-processor pre-processes enhanced data packets by coding the enhanced data packets for forward error correction (FEC) and expanding the FEC-coded data packets. A data formatter adds first null data into first place holders within each pre-processed enhanced data packet. A first multiplexer multiplexes the main data packets with the enhanced data packets having the first null data. A holder inserter inserts second null data into second place holders within an enhanced data packet outputted from the first multiplexer. A data interleaver replaces the second null data with parity data. A data generator generates at least one known data sequence. A symbol processor replaces the first null data included in an output of the data interleaver with the known data sequence(s). A non-systematic RS encoder generates the parity data by performing non-systematic RS-coding on an output of the symbol processor, and provides the parity data to the data interleaver.

摘要： A VSB demodulating device and method in a DTV receiver is disclosed, in which a VSB signal is received for independent carrier wave recovery and symbol clock recovery. An A/D converter samples the output of a SAW filter with a fixed frequency and converts the resultant value to a digital signal. A carrier wave recovery portion recovers a carrier wave from a base band pilot signal output from a multiplier, and a timing recovery portion recovers a symbol clock used for a transmitter using the output of a matched filter disposed in a base band. In this case, the carrier wave recovery portion and the timing recovery portion are independently operated without affecting each other. Thus, the carrier wave recovery portion is operated stably even in case where a fatal ghost exists in a band used for timing recovery. Furthermore, since a closed loop control can be implemented independently for carrier wave recovery and timing recovery, stability of the system is improved, thereby improving performance of the DTV receiver.
