    • Disclosed is a video camera apparatus including a video camera for generating a video signal and a camera control unit for generating a control signal for controlling the video camera. The camera control unit includes a video signal receiver, a video/reference signal phase comparator, a phase difference signal transmitter, a video signal memory, and write and read clock signal generators. The video camera comprises a phase difference signal receiver, a synchronizing signal generator, a synchronizing signal phase controller, an image pickup device and a video signal transmitter. In this setup, the output video signal is generated under stable genlock control for radio communication between video camera and camera control unit.
