What is IPTV (Internet Protocol television) ?

IPTV (Internet Protocol television) is a service that provides television programming and other video content using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, as opposed to broadcast TV, cable TV or satellite signals.

An IPTV service, typically distributed by a service provider, delivers live TV programs or on-demand video content via IP networks.

An IPTV system may be used to provide video content over a private network in an enterprise, although such implementations are far less common than subscriber-based models due to the complexity, network latency and scaling issues.
