These were the numbers presented at an Internet2 meeting about the 4k testing happening between UCSD and UW. I'm not sure what compression algorithm they were using for the test. On Tue, Dec 1, 2009 at 12:58 PM, Chris Adams <cmadams () hiwaay net> wrote:

Current over-the-air HD (at a max of 1080i) is up to 19 megabits per second (and most don't run it that high). Most cable systems compress it more. 4k video is roughly 8 times the pixels than 1080i, but is typically going to be compressed with better algorithms (MPEG4 is roughly half the size of MPEG2), which would mean 4k video (at TV quality) would be around 100 megabits per second. -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
