Although IPTV stands for Internet Protocol TV, it really is not over the internet but over a private network.
Gartner defines IPTV as the use of a carrier-based managed IP broadband network to deliver television and video content services to the end-user's TV set using a set-top box, and delivering picture quality at least equivalent to existing pay-TV or free-to-air services. Content delivered over the internet or delivered only to a PC is not included. Video content can be broadcast-style pay-TV, video on demand (VOD) or other video interactive services.
