They claimed they can stream 1.8 gigapixel video live or near real-time in the PBS video. Does anyone have an idea of how they can get that much bandwidth wirelessly ?
- blhack 14y agoI doubt they're sending the entire stream. 1.8Gp isn't useful to look at "zoomed all of the way out". The video is [probably] cropped onboard the drone down to whatever resolution is usable, and then that is streamed.
- CraigRood 14y agoIt's not absurd though for the military to have the capacity to bounce 600 gigabits/s around the globe. There are commercial sattelites with capacities beyond 110 gigabits/s
- biot 14y agoYou'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.
