Internet Protocol Television
In the most basic sense, it is a way of getting television transmitted over high-speed Internet connections. Broadband is revolutionizing television because it is a step up from conventional TV, which uses cable or satellite via analog or digital signals. Like VoIP, IPTV means video data is sent across the Net in packets of data.
It can then be stored on a server and sent to computers (or to a set-top box) over ADSL lines or cable lines. IPTV can be in the form of live TV, but it is more usually stored video, sometimes known as video on demand (VOD). To watch IPTV, a person needs a computer, or set-top box, plugged into the TV.
Because there is limited space for more TV digital or analog channels, being able to use the net as another way to distribute programs is seen as extremely attractive and almost limitless. In theory, it means that anyone with a server could set themselves up as an IPTV service. If more "channels" are needed, it is simply a case of more server space.
