Abstract
A wide-angle television system, such as one having 2:1 or 5:3 aspect ratios, provides N 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. Further, a receiver is provided wherein the picture is changed from the wide-angle display to the standard display by collapsing the horizontal scanning only. In another arrangement standard definition kinescopes having aspect ratios of 4:3 are masked in a special manner to provide a 5:3 aspect ratio display which may be collapsed to provide a 4:3 standard aspect ratio pictures.
