I'm no techie so here it goes: they say its IPTV in that the signal comes via internet protocals using a fiber optic cable. It's kinda like internet TV but from a private internet source. They say you get a vastly improved signal and picture. You do have to have a box for each TV to unscramble the signal. I think its like Verizon's FIOS system.
It's kinda like cable but better!
