Internet Protocol Television (IPTV)

                           As a result of broadband service providers moving from offering Connectivity to services, the discussion surrounding broadband entertainment has increased significantly. The Broadband Services Forum BSF) membership has identified a number of services that require significant focus in this decade; one of these is Internet Protocol Television (IPTV). This paper provides a high level, vendor&agnostic overview of what IPTV is and how it works.

IPTV, essentially, has two components:

Part 1: Internet Protocol (IP): specifies the format of packets and the addressing scheme. Most
networks combine IP with a higher&level protocol. Depending on the vendor solution, user
datagram protocol (UDP) is the most typical higher level protocol. The protocol establishes a
virtual connection between a destination and a source. IP allows you to address a package of
information and drop it in the system, but there’s no direct link between you and the recipient.

Part 2: Television (TV): specifies the medium of communication that operates through the
transmission of pictures and sounds. We all know TV, but here we are referring to the services
that are offered for the TV, like linear and on demand programming. Add the two components
together (IP+TV) and you have: IPTV: specifies the medium of communication of pictures and
sound that operates over an IP Network. Note: It is important to point out that IPTV services
usually operate over a private IP network and not the public Internet. In a private IP network
specifically designed for IPTV, a service provider can ensure quality of service (QoS) for
consumers. QoS refers to giving certain IP traffic a higher priority than other IP traffic. In an
IPTV network, TV signals are given the highest priority. As a result, the TV service is
instantaneous; there is no downloading involved for the linear or on&demand content. An IPTV service model offers a complete broadcaster and “cable programmer” channel line&up, including live programming delivered in real time. Additionally, it can offer a video on demand (VOD) service and enables the broadband service provider to develop new and unique services to differentiate their offering from competitors
