Abstract
A single chip system including a first input channel for receiving digital video input data, a second channel for receiving computer graphics data, means for synchronizing the two channels to one another utilizing timing signals which may be selected to provide the most accurate timing available, means for changing the rate of presentation of the computer graphics signals to match the rate of presentation of the video signals, means for adjusting the format in which the computer graphics signals are presented to the same format as the format in which the video signals are presented, and means for selectively blending the computer graphics and video signals furnished as video input data without modification for presentation on a single output display.
