Internet Protocol Television

Television streamed over high-speed Internet connections.

Unlike conventional TV, which uses cable or satellite via analog or digital signals, IPTV uses broadband. 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. If you are viewing the content as stored video, sometimes known as video on demand (VOD), you will need a a set-top box plugged into the TV. IPTV can also be in the form of live TV via live IP streaming platforms. Live IPTV eliminates the need for satellite TV antennas and set-top boxes.

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.
