IPTV is defined as the secure and reliable delivery to subscribers of entertainment video and related services. These services may include, for example, Live TV, Video On Demand (VOD) and Interactive TV (iTV).
Internet Protocol television (IPTV) is a system through which tv services are delivered using the internet protocol suite over a packet-switched network such as a LAN or the internet, instead of being delivered through traditional terrestrial, satellite signal, and cable television formats.
IPTV is short for Internet Protocol Television and is the latest and greatest way to view live television. In today’s digital world, viewing content including live television is available via the internet for instant access.
From a TV watcher's point of view, IPTV is very simple: instead of receiving TV programs as broadcast signals that enter your home from a rooftop antenna, satellite dish, or fiber-optic cable, you get them streamed (downloaded and played almost simultaneously) through your Internet connection.
