PROBLEM TO BE SOLVED: To provide a television device supporting suffering and a power failure.SOLUTION: A television device 20 comprises connectors 205, 215, and 225 which input normal communication signals such as USB and radio signals of digital broadcast received by antennas of portable terminals 10, 11, and 12 through the same signal line. Tuner units 240, 241, and 242 demodulate the radio signals. A USB interface 250, an HDMI input unit 251, and a video input unit 252 are transmitting and receiving means for transmitting and receiving the normal communication signals. Switches 200, 210, and 220 switch a radio signal to the transmitting and receiving means or the tuner. A synthetic diversity unit 260 performs synthetic diversity for the radio signals demodulated by a plurality of tuner units 240, 241, and 242 by maximum ratio synthesis or antenna synthesis. |
