Good grief. Don't try to develop something like this yourself. That's insane. Streaming media is a HARD problem and not something you put into a servlet.
Go look at RealMedia and buy their streaming video solution, or one of the other commercial competitiors -- that is unless you really WANT to waste a few million dollars in development...
