Abstract
A digital video stream is digitally scaled to properly display on a device having a horizontal to vertical aspect ratio different than the source aspect ratio leaving a blank area on the device. Graphic data is digitally scaled separately to extend partially or completely into and therefore use the blank area. A compositing blender digitally combines the two prior to a display encoder which produces analog signals for driving the display device.
