Abstract
A modular video switching system for switching a video signal from one of many video cameras to a video monitor. The system includes one or more individual modules each containing a limited set of input channels. The modules can be cascaded with each other to permit scanning of the video signals from all modules on to a single video monitor. Also provision is made for modular camera controls, requiring only a single control for all cameras, using modular circuitry to rout the control signals to the appropriate camera.
