A CDE Definition
The visual effect of black bars on the top and bottom of the screen when a movie with a wide aspect ratio is displayed on a TV that is not as wide. The black bars compensate for the reduced vertical height of the movie frames. This was a common experience on earlier TV sets if the movie was not reformatted for TV viewing (see pan & scan). The term "letterbox" was coined because the wide frame resembles the size of a letter envelope. See pillarbox, aspect ratio and anamorphic DVD.
