This is based on the possibility , puzzling as it
might seem that
1. Broadcast TV won't do it.
2. Everyone involved is rather lazy
3. There is at least one ethernet connected computer in each classroom or other viewing spot.
4. Direct Software cost (like buyng rec-coding stuff, ala adobe/real/microsoft) won't work.
5. Did I mention lazyness?
6. Zero to less network background,experience,etc
So, we have :
1. One computer that recieves the
main stream, (cnn, c-span, etc).
2. It also runs a VNC server (tight, real,
ultra,etc)
3. All viewing computers run a corresponding VNC
client, preferably set to relative low,but tolerable quality mode. preferably connected in
viewonly mode (so no 2nd graders pull pranks)
4. Central computer is in the principal's office
and the audio is piped over the public annouce
system (VNC not so good for audio)
Voila, all local area network computers can view
(& hear) and only 1 incoming stream is needed.
Cost: 0 in software, 4-8 hour in client computer
setup (teach email giving link to where to download VNC viewer).
No routing or multicast wizardly and everybody
gets to watch and listen (over the PA system)
Alt solution:
Every class takes a field trip to the Mall
(or wal-mart) electronics sections and watches
it on broadcast television there.
Downside to alt fix, costs fuel.
