<p>PURPOSE: To obtain the radio transmission reception circuit adopted for a video camera where its body section and a view finder are separately operated. CONSTITUTION: A timing control section 60 applied to a radio transmission circuit inserts an encoding signal to a video signal for a prescribed horizontal synchronizing signal period. On the other hand, a timing control section 140 applied to a radio reception circuit extracts the video signal in which a secret code is encoded and gives the resulting signal to a decoder 152. The signal decoded by the decoder 152 is discriminated by a reference code signal and a code discrimination device 153, and only when the codes are identical, the received signal is displayed on a view finder 172. Thus, an image is picked up while the video camera body and the view finder are separated at a location where the image is hardly picked up or there is any spatial restriction and an encryption code is easily set so as to avoid crosstalk from a video signal received from other radio video camera.</p> |
