ABSTRACT:
A video mixing system that is adapted to receive respective video and graphic control signals for controlling the display content on a video monitor. A video decoder processes the video and graphic control signals, thus making it possible to mix two or more video sources, one of which is typically an in-house data terminal source and the other of which is typically connected as a graphics option. At the output of the decoder is a gate means for providing selective voltage stepped intensity control signals for controlling the video monitor.
