The company has two major national video headends, where it downloads signals of all national program networks, including HDTV networks. Those national headends are connected to regional video hub offices via fiber. The fiber that constitutes Verizon’s national backbone has more than enough capacity to carry hundreds of new HDTV channels.
Each regional video hub office basically serves a single market. So Boston has its own video hub office, Tampa has one, suburban Philadelphia has one, and so on.
At those offices, local broadcast signals are ingested, including the HDTV feeds of local broadcast TV stations, plus other local access channels and regional sports networks. Like cable, the entire bevy of “local” channels, perhaps 20 to at most 40 channels (many of which are in analog), are sent to the home, along with all the national digital and HD channels. But between the regional video office and the home rests the central office, the final processing center for video signals before they hit a subscribers’ set-tops.
