Not exactly the right definition, nor is it 'weird'. They use signaling on the lines going back up TO the dish (or nearby multi-switch) to control which signal is sent back down to the receiver. It's possible for a dish to have more than two LNBs, thus the need to tell it which of the signals to send. I guess you COULD call that "bandwidth" but that's not really accurate.
I switched from DirecTV to FIOS. You only need one coax line going to the Tivo. I don't know that you can re-use the DirecTV cabling. You'd certainly need to remove any existing DirecTV multi-switches first (they look like a big splitter).
And we're not your "dawgs".
