  • Patent number: 4191971
    Abstract: A transmission line cable terminated at both ends is routed through a plurality of separate television cameras and a television monitor. Each camera includes a current source coupled to the cable. The video from the camera modulates the current source to produce a signal across the terminations without changing the impedance across the line.

  • Patent number: 4190863
    Abstract: A system for remotely controlling a color television camera includes a converter responsive to amplitude levels at control potentiometers for sequentially providing a binary digital representation of the amplitude levels at the potentiometers. A transmission line couples the binary output from the converter to the television camera to be controlled. The camera includes a digital to analog converter for sequentially converting binary signals back to amplitude levels and applying these levels to the TV camera control circuitry.
