IPTV Internet Protocol Television (IPTV) is a system where a digital television service is delivered to subscribing consumers using Internet Protocol over a broadband network. It is like cable TV, but it uses a broadband connection to the Internet instead of cable for the delivery of video & voice services.
IPTV system has four key components:
Head end (Includes antenna, receivers, encoders, digital turnaround system),
Middleware (includes a client-server service Management software),
Broadband transport and access network and
Equipment at the client’s Premises (includes modem & set-top box).
Main applications of IPTV are Digital Broadcast TV, Web access, VOIP (Voice over Internet Protocol), Video on Demand (VOD) and Music on Demand. Many of the major telecommunication service providers are exploring IPTV as a new revenue opportunity from their existing markets.
