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： Provided is a carrier recovery apparatus in a vestigial sideband modulation (VSB) type digital television (DTV) receiver. The carrier recovery apparatus dynamically controls a sign determination level which is a reference for determining a sign of an I signal in a sign extractor. Therefore, the carrier recover apparatus can eliminate unnecessary sign extraction caused by zero-crossing which is generated when the receiver receives a pilot signal weaken by a channel ghost, and improves the frequency lock performance in the receiver. Specially, the carrier recover apparatus can effectively improve the frequency lock performance when comparatively large pattern jitter is existed in a low pass signal caused by a ghost signal produces a long delay time.

A data formatter generates enhanced data packets including the pre-processed enhanced data and inserts known data to at least one of the enhanced data packets. A first multiplexer multiplexes the enhanced data packets with main data packets including the main data. And, an RS encoder RS-codes the multiplexed main and enhanced data packets, the RS encoder adding systematic parity data to each main data packet and adding RS parity place holders to each enhanced data packet. Herein, the RS encoder may insert non-systematic RS parity data or null data into the RS parity place holders included in each enhanced data packet.
