No, this is done at what's known as the headend (where all the cable connections come into the cable company). They'll do what is known as recombining and channel additions.
I phrased my question badly, that's what I meant to ask... and thought would be the case. This interested me, because Buford GA is pretty close to our neighborhood.
Thanks for the info on what they might be doing even though we users aren't experiencing any regular problems out here.
