Abstract

The invention provides an apparatus and method for displaying video pictures. The apparatus comprises a picture display screen (630) having a first aspect ratio and a picture decoder (610) for decoding a video signal including at least one picture. The picture has a second aspect ratio. In one embodiment of the invention, the second aspect ratio is different than the first aspect ratio. A picture aspect ratio detector (622) is coupled to the picture decoder. A border generator (620) is coupled to the picture aspect ratio detector. The border generator provides a border for the picture. The dimensions of the border are based, at least in part, on the detected picture aspect ratio.
