plugged into the iphone? that's my video transmitter. now this is my video repeater. basically it takes any video signal coming out of the iphone and enhances it. i can take over any other video signal that i want that i put this close to. >> he thenys the video he just recorded first on small screens close to the ground. and then attaching the device to a large red balloon on a jumbo screen high overhead. the images on the phone and on the screen are perfectly in sync. so, real or fake? what do you think? no hacking here. the transmitter and receiver are random spare parts picked up from a used electronics store. but the video is playing for all to see. the company behind it just leased the screen space and played the video back like any other advertiser would.
