The design of a modular compact three-tube color camera particularly suited for use in cable television includes only the operational features required for CATV origination. The design is based on the prism beam-splitting system and three camera tubes. Either 1-in vidicon or 1-in Plumbicon tubes can be used. Two basic versions can be obtained because of the flexible modular design. The operation of the camera is automatic to a high degree; it is equipped with a 7-in electronic viewfinder and a video switching/audio unit. This unit contains the switches for the viewfinder video and input connectors for an external video signal, intercom headset and program microphone. The standard lens for the camera is a f/1.7, 25-125 mm zoom lens.
