ANNOUNCER: A CNN viewer wants to know "How did CNN bring live pictures from Hainan of the U.S. plane departing on Wednesday night?"</s>JUDY WOODRUFF, CNN ANCHOR: As you can see, we keep changing the lenses on the camera, and I've been asking our technical wizards here at CNN what this camera is. All I can tell you so far is that it is a videophone.</s>BILLY SIMONS, CNN SATELLITE COORDINATOR: In a nutshell, it's hooking up the camera to the videophone, the videophone to the satellite phone, the satellite phone up to a specific satellite, and back down to a receive unit, which is actually in London or Atlanta, or anywhere that you have the receive unit. You just need the correct phone number to dial into. Essentially, it works exactly like a regular phone call.</s>WOODRUFF: But these pictures are transmitted by a telephone line, and these are digital pictures. Therefore, there's a slight graininess in what we're seeing.</s>SIMONS: The picture updates about 15 times per second.</s>JOHN FIEGENER, CNN PRODUCER: So, that gives it that jerky motion. However, as you can see from the size, you can carry it on the plane and it runs off of 12-volt batteries. So it's extremely portable.</s>UNIDENTIFIED FEMALE: This is a fairly easy setup. It's easy for us to put up. We've been able to do -- bring you live pictures on relatively short notice.
