Drifting off-topic, but those are 'raw' data rates. Compression algorithmsalong with motion-estimation allow you to get full-screen video down to ~1.5 Mbps with not much in the way of image quality loss.Raw HDTV is about 1.2Gbps. RAW NTSC SDI bitstream is a few hundred. The 6 and 19.8 are already compressed. Obviously putting more horsepower to the compression you can achieve smaller data rates. However applyingfor example MPEG4 instead of MPEG2 for 1080i or 720p ups the computationalrequirements beyond current consumer state of the art.
The first MPEG-4 HD set top boxes are beginning to appear http://www.sigmadesigns.com/news/press_releases/030108.htm Watch this space.... Regards Marshall Eubanks
