In a word: licensing. There is nothing "technical" about it. Plain and simple, Blu-ray licensing is a tangled mess, and, thus far, is not a certainty anyway. Given the speed at which the world is shifting toward on-demand HD, I would say that Blu-ray will be relegated to an "also ran" format long before anyone thought possible.
I was responding to the above
my question/statement also remains. Streaming content will never be as good as hard media until bandwidth allows for it. We are YEARS away from that happening.
In the meantime - all those in favor for settling for mediocrity in picture and sound while boasting they are getting HD streamed to their houses - go enjoy those services. The rest of us will keep our blu-ray players...
One valid answer would be:
any household with a mostly reliable internet connectionof course, that "720p stream" would have to be horribly compressed and probably only a couple of frames per second - but it could be done without hiccups.
If you want 24-30 fps and a high quality bitrate for video and audio of 10-15 Mbps, the answer would be
very few householdsNote that not many people consider Apple's 720p streams to be "high-quality bitrate" - sending 720p at half the bitrate of an SD DVD is not acceptable to many.
