Steve Jobs keynote speech - how to get that quality and speed?

I watched Steve Jobs keynote speech with interest and envy.
How is it possible to get the video quality so good combined with so fast download - even on a relatively slow bandwidth I could more or less instantaneously scroll to the end?
I run a local net based TV station in Denmark http://www.tv-moen.dk and would love to supply that quality and speed. Can anyone help, please?
Sincerely
