| there's a difference between TV and Internet. they can "broadcast" IPTV all over the place w/ a limited bandwidth, 25mbps. so, to provide IPTV to a 100 house neighborhood, all they need to bring is a 25mbps pipe to the neighborhood and broadcast the same packet to each house.
but in order to provide 25mbps worth of internet to every house they serve, they'll need to bring much bigger pipe in to the neighborhood.
i'm not saying this is exactly how it'll work but you get the picture...
i hate latency in my satellite tv.

Where did this information come from? Not disputing what you have said, but how can you fit 100 channels on a 25mb 'pipe' for 100 houses with each one of those houses theoretically watching different channels? |

| let me correct myself. (again, i'm not saying this is how it works. only my theory.)
i should have said they would have to bring about 155mbps(oc3 speed) into a neighborhood. this should be plenty to carry about 10 HDs(6mbps) and 60 SDs.(1.5mbps). all channels are broadcasted to the neighborhood hub from the main(?) location(co).
from the neighborhood hub, they run a 25mbps pipe to each house in the neighborhood. this allows each person to watch up to 4 HDs at a time... channel tunning is done at the hub hence the provider doesn't have to lay a bigger fiber to deliver all channels to every house. you can only watch so many channels at a time.
i'm just saying 25mbps is plenty to deliever up to 4 HDs.

| Interesting discussion for BROADCAST.
However, I saw a press report that said all SBC/MS offerings would be PPV or a similar "request" basis--meaning the bandwidth economies of scale you get with broadcasting won't apply....

You are correct, unlike cable with dsl you don't share bandwidth with your neighbors. Each dsl customer will have 25 MEG "pipe" for there use. Voip, internet, tv, or whatever you they wish to do with it. |

@centurytel.net | SBC Im sure will have a solid backbone set up for the traffic im sure. If there spending that kind of money im sure they've done there research. |
