A wide-angle television system, such as one having 2:1 or 5:3 aspect ratios, transmits end portions that exceed the limits of a conventional 4:3 aspect ratio picture in regions that are normally hidden from view in a conventional receiver. Thus the system is compatible with such a receiver. These regions can comprise the overscan region, blanking intervals, high frequency portions of a chroma signal, etc. Time compression of the end portions can also be used. At a wide-angle receiver, inverse processing is used to reassemble a wide-angle picture.
