Abstract
In an apparatus for displaying the picture information of an incoming interlaced television signal in noninterlaced raster scanning display on the faceplate of a picture tube, each video line of the television signal is separated into R, G and B color component signals. Each video line is compressed, or speeded-up, at a variable rate and delayed by a variable delay time to provide a speeded-up signal that is coupled to the corresponding electron beam gun of the picture tube. Each of the variable rate and delay is controlled in accordance with information relating to distortions of the raster scanning display. In this way, distortion, such as east-west or convergence, is reduced when the speeded-up signal is displayed.
