You'll notice that all the windows the guy brings up are simply video players with progress bars that show where in the video it displays. So that's how the real-time is done for PBS. :) All that wonderful dragging around of windows is standard touchscreen mouse cursor functionality. I wouldn't be surprised if the top-secret stuff is just a bunch of empty boxes and a beach ball covered by a tarp. In a real-life scenario, it likely only streams enough pixels to show you the area(s) you're interested in. So you can take advantage of 1.8 gigapixels by selecting which 1M pixel area you wish to focus in on and that feed gets streamed to you. If you focus in on multiple areas simultaneously, it is likely to support as many 1M pixel streams as the bandwidth allows with degrading quality (lossy compression) beyond that.
