Abstract of the Disclosure When combining two video signals on a television screen it has been common practice to extract from the two video signals only those portions required and display those portions together on the screen. A problem arises if a desired portion of one video signal coincides with a desired portion of the other video signal because, in that case, only one of the two portions can be displayed. The present invention permits this problem to be overcome without changing the camera position or angle or moving the subjects or scenes being shot. One of the video signals is operated on in a special effect device where it is divided into portions shifted apart from each other according to an external control signal. The actual configuration and spacing of the portions can be varied by varying the control signal to en- sure that the various portions of the one video signal do not coincide with desired portions of the other video signal.
