Deployment of IPTV over IMS architecture

IPTV is a system used to deliver digital television services to the consumers through broadband. This delivery of digital television is made possible by using Internet Protocol over a broadband connection, usually in a managed network rather than the public Internet to preserve quality of service guarantees. The Internet Protocol (IP) multimedia subsystem, better known as ldquoThe IMSrdquo, is based on the specification of the session initiation protocol (SIP) as standardized by the Internet Engineering Task Force (IETF). IMS is an architecture for the convergence of data, speech and mobile networks and is based on a wide range of protocols, of which most have been developed by the IETF. It combines and enhances them to allow real time services on top of the universal mobile telecommunications system (UMTS) packet-switched domain. This paper presents various standardization efforts for IPTV, deployment of IPTV over IP Multimedia Subsystem. It further also deals the advantage of IMS based IPTV, its implementation challenges, performance and capacity , and testing requirement.
