Hi Kimmarie,
Virgin TV boxes have always used a broadband connection, if you currently have an old TiVo box that has a modem built in so it might not be obvious that it is connected to broadband, the V6 and 360 boxes both require 2 connections, the coax for live TV and a internet connection either by ethernet cable or wifi for everything else, on demand, box updates etc.
Edited to say someone moved this answer from the 360 board to the manage your account cable board.
