Apple's video technology

[MacBH928]

Hello,

I was watching Apple's event on quicktime , and the whole 1:30 hour show streamed with no pre-downloading on my slow internet connection(512kbs at best)

while youtube videos of 5 and 10 min will take very long time to load, actually they won't stream ever, all the time they will need to be downloaded at first, this goes for html5 AND flash.

what is this technology apple is using to stream video?
Why can't other websites utilize it as it is much more convenient
can you benefit using it on your own personal website?

YouTube videos that I watch always essentially 'stream'...I never have to wait for the whole video to load.

It all boils down to bandwidth and video quality. From my end (very mediocre bandwidth), the keynote was far from being HQ but good enough not to miss anything important.
I don't know the accurate technical answer to your question, but I would think they use some tech that automatically adjust video quality to the measured bandwidth of the client.
Youtube uses fixed resolutions and FPS so if your internet is slow, it won't stream properly.
