The present invention relates to a tuner module capable of inputting an analog signal and a digital signal simultaneously. The tuner module is connected to a first signal source, a second signal source and a TV set, wherein the first signal source provides an NTSC analog signal, and the second signal source provides a DVB-T digital signal. The tuner module comprises a switching switch used for switching an output of the switch to the NTSC analog signal provided by the first signal source or a DVB-T digital signal provided by the second signal source, a tuner unit used for reducing a signal outputted by the switching switch to a predetermined frequency, a first demodulation unit used for carrying out demodulation processing on the signal outputted by the tuner unit so as to output an audio-video signal, and a second demodulation unit used for carrying out demodulation processing on the signal outputted by the tuner unit so as to output a transmission series stream.
