How to hack video screens on times square’ documents the allegedly successful attempts of YouTube user BITcrash44 to hack various screens in Manhattan’s Times Square using an iPhone4, a transmitter and video repeater.  In total three screens were taken over, including a large monitor only reachable with a large helium balloon.

BITcrash44 claims you can play back any video clip;

…through the ipod feature or through the camera roll. The transmitter instantly sends the video signal to the video repeater and the video repeater overrides any video screen that it’s being held next to. It doesn’t matter what shape or size the hacked screen is because the hack video will simply keep its correct dimensions and the rest of the hacked space will stay black.</p>

I chose times square for my demo because it has lots of video screens to try it on. It is also one of the most monitored and secured areas in new york city and that made it that much more fun. You can see in my video that the repeater is pretty powerful but the signal is not very stable yet. I’m working on that.

A new video is supposedly on its way, which will detail the making of the prototype.
