If you are watching an uncompressed 1920x1080p movie, is this how to calculate the bandwidth needed...

1920x1080 (resolution)
x
30 (fps)
/
8 (Bytes / sec)
/
1024 (KB / sec)
/
1024 (MB / sec)

==

7.42 MB / sec

That starts with the video produced from 1080p cameras. At present, 720p and 1080i cameras output video at about 1.5 Gigabits per second, but 1080p would roughly double that to 3 Gbps, Pagano says. To convert that into a standard 19.4 Megabit per second channel for transmission across a cable network, ?there?s a whole set of other technologies that have got to be accomplished in between there.?

I get around that but for 24 frames/sec.
My highly uber technical method (not really) - save a frame of one of goosemaster's 1080i clips. on average comes out to about 7.5 MB/frame. multiplied by 24 = 180MB/s.
