In this article that speculates about an Apple TV upgrade, there is an interesting tidbit that validates what I and others have been saying for a long time: HD content chews up bandwidth:
"...In turn, consumers would see a similar increase in streaming requirements. Xbox Live can stream 1080p video, but it requires 8-10meg broadband, which leaves an awful lot of people out in the cold. It has the option of downloading instead, but if you're out in the sticks on a 2meg stream you're looking at more than eight hours to download your film at 1080p. You'd best plan your Friday night viewing before leaving for work on Friday morning."
The discussion about the Apple TV is whether or not Apple will include the ability to show movies in HD 1080p format. The short answer is, "Not likely," because streaming 1080p movies and TV shows over the Internet requires a massive chunk of bandwidth--8-10 megabits. And that's REAL bandwidth, not the marketing happy-talk that always begins with "....up to..."
Notice that if you wanted to download that movie over your average 2 megabit connection, it would take more than 8 hours! And if you are on a cable modem connection with a few of your neighbors also trying to do the same, it would take a little longer, like never (ditto with a wireless connection).
The answer is simple: we need to switch to open fiber.
