Abstract
A font recall system stores a font of alpha-numeric characters in a video display format for selective insertion as a caption into a video image. Characters are stored on a video disk in digital pixel form with full dynamic resolution. Low pass filtering is employed to preserve high image quality and eliminate jagged edge aliasing at character boundaries. A first frame store receives selected characters from the video disk through an image size reducer to store the characters at selected display positions with a selected size to form a caption under control of a central processing unit. A keyer receives the caption video data from the first frame store as well as a background image to form a composite image, which is stored in the second frame store before being output as a continuous television video signal.
