ABSTRACT:
A system and circuit for selectively presenting to a display terminal information obtained from a video camera and from a computer terminal so that computer generated graphics information can be superimposed with the camera picture on the face of a display screen. An interface adapter circuit is coupled to the computer's address and data buses and is used to drive a video mixing switch to provide a computer monitor with either computer generated graphics or video information originating at a video camera, with synchronization for the camera provided by the computer terminal.
