[MLB-WIRELESS] Nasa Tv over MW

[Mike Dickens]

I can't answer all of your questions but I'll answer the easier ones to save
the real tech-heads more time.
"More importantly however what would happen if say 100 people all wanted
to watch NASA TV at the same time on the network eg due to a shuttle
launch? Would the streaming tv have to be carried 100 separate times
across the network thus overloading the system or is there some way to
distribute one signal across the network and people can just passively
receive the streamed packets?"
It'd have to be carried 100 times. That being said, it could be 'cachied' or
'proxied' on more localised nodes (probably the closest unix routing box, if
it took off), so your end would only be transmitting it a few times then the
node closest to the user would deal with it.

"Do we have the bandwidth at MW to carry a TV signal?"
Depends. If you recompress it to a 'broadband-size' stream (so maybe 768
kilobits/s or something), then it'd be alright, but ofcourse thats only for
a few viewers. It'd be a big strain unless it was cached at multiple points
closer, so it didnt have to tie up the MW backbone
