Movie theater IR cluster

[JBotAlan]

So...we have been contemplating the use of this infrared board, and I guess my mind has been churning on that a little too long...I figured I'd share this.

I was sitting in the back of the theater, and I noticed a red box that looked like it had an array of LEDs in it. I pointed my cameraphone at it...and sure enough:

(only I would be freakish enough to not only have a camera in the theater, but to be pointing said camera at the back of the theater, not at the screen... )

Any ideas as to the purpose of this? I heard somewhere that camcorders use infrared to auto-focus; could this be a jamming device? If so, why would it not be in the front of the theater? This is right above the projection window in the back.

Ideas?
