Also referred to as internet TV, it is a television service that is delivered over internet using Internet Protocol. All the content including movies and songs are delivered through broadband connection rather than a cable.
Internet TV is one step ahead of not just cable television but also satellite television as content is delivered in the form of internet packets and received by the television of the viewer with the help of a set top box. Triple Play is the name given to the service where the customer not only enjoys IPTV but also VoIP and internet. If you subscribe to triple play, you can access internet, make long distance calls at very cheap prices using VoIP, and also get nonstop entertainment in the form of IPTV.
You get to watch video on demands on IPTV. This is called unicasting whereas there is also multicasting in which live programs are aired on television sets of subscribers.
