In-flight entertainment systems provide entertainment for passengers on commercial airline flights. Presently, usually on longer flights, video entertainment is commonly available on in-flight passenger entertainment systems. In-flight entertainment systems can display video on a variety of display monitors ranging from a conventional CRT display to a more modern Liquid Crystal Display (LCD).

Because embodiments of the invention use an existing command, which can be the repeated without affecting the functioning of legacy systems, the need for modification of the airline and monitor systems is greatly reduced.
