As things stand, empty voids at the top and bottom of an iPhone or iPad display come as standard with every widescreen video you might care to watch - a problem that almost persists with the iPhone 5, since that phone's elongated panel is still a few pixels off 16:9. However, judging from paperwork recently filed with the USPTO, which mentions both mobile and TV displays, Cupertino thinks it has a general workaround: using a Photoshop-style technique to copy colors from each frame of video and use them to sympathetically fill in the letterbox bars, mimicking the appearance of full-screen footage.
