<p>A satellite broadcast receiver comprises an antenna, a tuner, a modulator, a FEC decoder, a microprocessor, and an antenna driver. The antenna receives the satellite signal and the tuner tunes the satellite signal received by the antenna, and the modulator modulates the satellite signal tuned by the tuner into digital signal, the FEC decoder corrects a position error of the satellite antenna using the signal modulated by the modulator, and outputs a corresponding output signal, and the microprocessor receives the signal modulated by the modulator and the output signal of the error corrector, and outputs a control signal which controls the position of the antenna, and the antenna driver drives the antenna in accordance with the control signal of the microprocessor. The satellite broadcast receiver enables a user to detect satellites fast and see satellite broadcast conveniently. <IMAGE></p> |
