Well, a ‘Jumbotron’ is an old school name for Sony’s giant screens… Strictly speaking, Jumbotrons don’t exist anymmore, although there are plenty of big LED screens you can rent… But thats a tangent.
You need a multi display processing system. Something like an Electrosonic Quantum, a Dataton Watchout, an AVStumpfl Wings Platinum setup, or the like. In the bay area you’ve got Creative Technology (they’re a really big company, they’ll probably have several options for rent), you probably have one of the general trade show AV players like AVHQ, and also Large Screen Video. LSV is a great choice for that sort of thing…
Good luck…
