Abstract
An audiovisual processing system comprises a signal receiving circuit and a host device. The signal receiving circuit comprises a tuner and a demodulator. The tuner generates a tuned signal based on a radio frequency signal. The demodulator generates a digital signal based on the tuned signal, generates a frequency down-converted signal based on the digital signal, generates an audio processing signal based on the frequency down-converted signal in an audio processing mode, generates a demodulated video signal based on the frequency down-converted signal in a video processing mode, generates an output signal based on the audio processing signal in the audio processing mode, and generates the output signal based on the demodulated video signal in the video processing mode. The host device receives the output signal, and generates a demodulated audio signal based on the output signal in the audio processing mode.
