A multiple TV signal tuner 1 comprises a plurality of signal receivers 111, a signal-processing module 12, a decoder 13 and a transmission interface 14. The signal receivers 111 are adopted for receiving and transmitting external digital or analog TV signals. The signal-processing module 12 is electrically connected to the signal receivers 111 and is adopted for receiving and demodulating the TV signals transmitted from the signal receivers 111. The decoder 13 is electrically connected to the signal-processing module 12 and is adopted for receiving and decoding the demodulated TV signals from the signal-processing module 12. The transmission interface 14 is electrically connected to the decoder 13 and is adopted for transmitting the TV signals decoded by the decoder to a host end for display. The TV signal may be received through one signal receiver 111 and transmitted to the other signal receivers (see fig. 3). The invention allows a plurality of analog and digital TV programs to be played simultaneously. |
