Referring to distribution of television programming over a network running the IP protocol.This approach delivers each TV channel only to the subscriber premises that select to view it, rather than broadcasting it to all stations on the network.The primary focus on IPTV is from telephone companies offering voice, Internet access, and TV programming over broadband fiber optic local loops conforming to passive optical network (PON) standards. See also broadband, broadcast, channel, fiber optics, IP, local loop, PON, and TV.
(Internet Protocol TV) Also called "TV over IP" and "Internet TV," IPTV refers to the delivery of scheduled and video-on-demand (VOD) TV programs and movies over the Internet. By the end of 2009, the telephone companies had nearly 40 million IPTV subscribers worldwide. See Internet TV. IP Triple Play All Web and e-mail traffic travels in IP packets, and voice increasingly uses IP (see VoIP). By adding IPTV, a data-voice-video "triple play" service can be offered over the same network infrastructure. See triple play. Like a Web Page IP-based TV is delivered like a Web page. When a subscriber wants to view a TV channel, that channel is routed to the user just like every other resource on the Internet. In contrast, a cable TV user receives hundreds of channels over the cable simultaneously and tunes in to the one desired. See Internet TV, Internet Protocol, streaming video and IP on Everything.
