Digitally controlled color cameras and a two-way CATV cable make it possible to completely change the operating procedure in the origination of on-the-spot television pickups. Simply, the two-way CATV cable makes it possible to use this link as the "camera cable" between the digitally controlled color camera and its control unit. In the operation of the multiplexed type color camera, signals are sent to and from the CCU on RF carriers. These signals are compatible with those normally transmitted on CATV cable and include video, audio and control signals. The new two-way CATV cable can replace the coaxial-type camera cable, thereby requiring only the camera head to be transported to the field. All other remaining peripheral equipment can then remain in the broadcast center in its controlled environment. This system of operation offers potentially large savings in equipment and manpower. Some of the details of normal color camera control requirements, how the digitally controlled color camera operates, the signals on the coax camera cable and the capability of the two-way CATV cable to handle these signals are reviewed.
