Bdale's right about there not really being any need for us to adhere to Amateur DTV or any other digital TV specs. I tend to look too far into the future toward an orbiter that broadcasts video that amateurs could receive. Obviously anything available now will be horribly archaic by then :-)
I am no fan of digital video compression for several reasons. I won't go into it here other than to say that IMHO video compression is horribly lossy (re: our latest launch video) and that compression efficiency goes way down with detailed images that change rapidly over time -- like the view from a rocket that spins and looks at clouds and sagebrush. Frank (I'm biased -- many years ago I had the good fortune to see Japan's analog HDTV at the Sony building in Tokyo. Obviously this was a best case scenario, but it was beautiful -- far, far better in all respects than American Digital HDTV -- a high bandwidth, but well worth it.) _______________________________________________ psas-avionics mailing list [email protected] http://lists.psas.pdx.edu/mailman/listinfo/psas-avionics
