摘要：
The present invention provides a digital video broadcasting - terrestrial (DVB-T) system and modulation method thereof. The system comprises a transmission module and a receiving module. The transmission module modulates a video signal to a DVB-T signal. The receiving module receives the DVB-T signal via a transmission line and demodulates the DVB-T signal to the video signal, and at the same time, monitoring the signal-to-noise ratio (SNR) or bit error rate (BER), and quantizes them to a reference data. The receiving module transmits the reference data to the transmission module through the same transmission line. The system can determine a control parameter according to the reference data to set the modulation parameter of the DVB-T signal.
