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.
http://www.bbc.co.uk/blogs/bbcinternet/2008/09/super_hi_vision.html "The Italian broadcaster, RAI, demonstrated satellite broadcasting of SHV at 140 Mbit/s from Turin to IBC." Super Hi-Vision has a resolution of 4320x7860 (and also carries 22.2 channel sound). IIRC the video codec used was Dirac.
From the Dirac website:-
"In our first experiments, we managed to get excellent picture quality at 128Mb/s, which sounds huge but is equivalent to just 4Mb/s for HDTV."
