Encoding apparatus for a closed circuit television system










Image Number 2 for United States Patent #4490742.

Apparatus for generating an indicator on a remote monitor screen representative of the orientation of the monitoring camera. A sensor on the camera produces a signal proportional to the camera orientation. An encoder, including a sawtooth generator, a comparator, and time delay single-shot multivibrators, is synchronized to the camera video horizontal and vertical synchronization signals to provide a camera orientation indicator on the monitor. A modulator at the camera superimposes the encoded indicator signal onto the camera video signal thereby producing a single composite signal for transmission preferably over a single video or RF cable to the monitor.
