Abstract :
The mixing of two video sources up to now has been accomplished by using discrete analog components. The new LSI video display processor (VDP) is the first integrated circuit with the provision for mixing, under software control, an external composite video signal with its own 15 color single pin composite video. The mechanics of this interface and its implications are discussed.
