TV Camera system having synchronized oscillators in camera head and CCU

摘要

In a television camera apparatus comprising a camera head, a camera control unit, and a camera cable for transmission of signals between the camera head and the camera control unit, the signals to be transmitted modulate frequency signals corresponding to integral multiples of a reference frequency, and the modulated signals are mixed and transmitted by means of the single-core camera cable. Oscillators to produce reference frequency signals are provided respectively for the camera head and the camera control unit, the oscillator of the camera head being controlled for synchronism by the reference frequency signal of the oscillator of the camera control unit or vice versa.
