Once upon a time, Steve Gibbard <scg () gibbard org> said:
iTunes video, which looks perfectly acceptable on my old NTSC TV, is .75 gigabytes per viewable hour. I think HDTV is somewhere around 8 megabits per second (if I'm remembering correctly; I may be wrong about that), which would translate to one megabyte per second, or 3.6 gigabytes per hour.
You're a little low. ATSC (the over-the-air digital broadcast format) is 19 megabits per second or 8.55 gigabytes per hour. My TiVo probably records 12-20 hours per day (I don't watch all that of course), often using two tuners (so up to 38 megabits per second). That's not all HD today of course, but the percentage that is HD is going up. 1.1 terabytes of ATSC-level HD would be a little over 4 hours a day. If you have a family with multiple TVs, that's easy to hit. That also assumes that we get 40-60 megabit connections (2-3 ATSC format channels) that can sustain that level of traffic to the household with widespread deployment in 2 years and that the "average" household hooks it up to their TVs. -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ NANOG mailing list NANOG () nanog org http://mailman.nanog.org/mailman/listinfo/nanog
