Abstract: An apparatus for altering the position of a video image, such as an image produced by a video camera, video tape recorder or other image producing device utilizing a raster type scan, without rescanning of the originally generated image alters, by a precise amount, the phase of a video camera or playback device with relation to the overall system or plant sync, while maintaining exact sync timing relationships for all timing pulses fed to the video camera or playback device. The video from the camera or playback device is processed so as to restore its blanking and sync timing to match the timing of other video sources within the system.
