This is pretty nifty. I was yapping with a friend of mine the other day about how the phone companies will deliver vDSL (Video over DSL), he's now at Boeing working on DirecTV's new sats. Here's how it works, and it's so simple you won't beleive it:
It's basically video over internet.
Each channel will have an IP address (which you'll never see). Your tuner acts just like the DirecTV Spaceway Internet service, only its tuning an IP video feed. Download speed is maxed at around 50 Mbps per feed. Ironically, this is how many HD feeds get to the head ends of cabel co's for some local programming, they call it ASI. Directv does nothing but pass through the feed.
Here's a company that provides the ground equipment for stations and headends.

In the end, when everyone is swapped out, all of DirecTV's feeds will operate this way. Two way feeds would be on the Ka system and one way feeds on the Ku system. Best part about it, very high tolerance for rain fade.
