Changing videos on the jumbotron possible?

[KyotoCarl]

Was just thinking about what is shown on the jumbotron. At the start of the game you see some team logos being displayed on it. Would it be possible to encode an .avi or .mpeg movie to be shown instead? How cool wouldn't it be to have some sort of highlight reel or a movie of a player, kinda like they have in Orlando, shown on the jumbotron before the game starts?
