Abstract
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.
