CONSTITUTION:The system is provided with a camera control panel 4A(4B) to designate the image pickup position of a camera 2A(2B), a camera controller 5A(5B) which measures a transmission delay time till the controller 5A(5B) receives a camera control signal from the camera control panel 4A(4B) and controls a camera 2B(2A) of an opposite station and receives a camera control signal from a called party to control the camera, a transmitter 6A(6B) which multiplexes a video/audio signal of its own station and the camera control signal, outputs the multiplexed signal to a satellite line 7, and demultiplexes the video/audio signal and the camera control signal from a received signal through the satellite line 7, and a camera system having a universal head 3A(3B), the camera 2A(2B) and a monitor 1A(1B). |
