Abstract
Apparatus for superimposing graphic title image signals onto an input video signal to produce a video picture having graphics, such as title images, superimposed thereon. Graphic title image data is written into a memory and subsequently is read out under the control of an address generator whose read-out addresses are shifted at a given repetition rate to change the positioning of the graphic title image data relative to the video signal, thereby producing a scrolling effect of the graphics across an image plane.
