Letterbox

A method used to show higher aspect ratio (e.g. 16:9) images on a low aspect ratio (e.g. 4:3) display. While all the contents of the pictures can be seen there are strips of (usually) black above and below the picture which some people do not like. Now that nearly all viewers have 16:9 screens, the use of letterbox is passing into history.
