PURPOSE:To satisfactorily transmit the video signals of plural systems at the time of transmitting the video signals by using an infrared-ray wireless transmission system. CONSTITUTION:The infrared-ray wireless transmitter-receiver used for the system which FM wireless-transmits the video signals by using infrared rays is equipped with a means 5 which judges and detects the synchronous signals of the video signals, plural low-pass filters 3 and 4, and switching means 6 which switches the output of the low-pass filters 3 and 4, and outputs it. The low-pass filters which control the bands of the demodulated signals are selected by the output of the deciding means 5 which decides the system of the video signals. |
