cozmicray - 22/6/2007 5:01 PMISS now has HD cameras and HD downlink.Have you seen much HD from ISS?Once again NASA can't cash in on incredible video from space!
Danderman - 23/6/2007 10:58 AMAt some point, it might be more effective for shuttles to bring up very large external hard drives to plug into the ISS storage system, to bring down very large amounts of HD data. I would suspect a kilogram sized hard drive could bring down a terabye of data that would otherwise clog up TDRS.
Lee Jay - 24/6/2007 4:56 AM1 TB of 4GB SD cards would weigh around 1/2 kilogram.BTW, IMAX camera images are way, way, way higher resolution than HD video. HD video is 1920x1080. The IMAX film frames are higher than that by (arguably) 3-10x in each direction, depending on film type and sensitivity.

HD video is 1920x1080. The IMAX film frames are higher than that by (arguably) 3-10x in each direction, depending on film type and sensitivity."way way way" is around 5 times the resolution (modern digital image sensors actually have a higher resolution than film albeit at a lower dynamic range and sensitivity). Which, of course, leaves you with 25 times as many pixels. But then image compression algorithms scale well, so I guess you will habe around 3-4 times the data needed for HD.
So where does all this HD video go ? There's a page of some HD video including one from ISS Expedition 13. I'd like to see more, but I guess it takes time to process and get this video out there.
