<p>PURPOSE:To eliminate the need for the cable of a television camera and to reduce restriction to transfer, by providing the television camra device with a high frequency signal generation part, transmitting a radio wave through modulation which uses a video signal and a magnetic video recording playback control signal, and receiving and demodulating the radio wave. CONSTITUTION:In addition to a television camera part 3, a television camera device 1 is provided with a magnetic video recording reproducing device control signal generating circuit 4 and a transmitter 5, and a radio wave modulated by the video signal of a camera part 3 and the control signal of the control signal generating cirlcuit 4 is transmitted from an antenna 6. This radio wave is received by a receiver 7 through an antenna 8 and demodulated by a demodulating circuit 9; and its demodulation output is separated into a video signal 10 and a control signal 12, which are amplified and inputted to a VTR part 11. Thus, the need for a camera cable is eliminated to eliminate limitations to the movement range of the camera, improving the mobility of video recording.</p> |
