Abstract

PURPOSE:To realize superimposition of an addition signal on a picture signal just through one superimposing part, by adding a superimpose signal to a picture control signal. CONSTITUTION:A superimposed signal is added with a picture control signal at an adding part 4 using a TTLAND circuit 7 via TTL forming parts 5 and 6. This addition signal is superimposed on a video signal at a superimposing part 3. In this way, only one stage is sufficient for the part 3 to reduce the hard quantity.
