What is IPTV? how television over internet work?

IN the 21st century the access with broadband internet and downstream data rates of several Megabit per second (Mbit/s) is making steady progress. With the increasing number of households are getting used to video streaming and download, using the Internet Protocol (IP) to enable interactive retrieval of video content from the Web.

This type of IP based television service is known as WebTV.

However, WebTV does not provide a guaranteed quality of service (QoS). Therefore now the telecommunication companies are making an attempt to overcome the deficiencies of WebTV and launched the so-called IPTV.

Internet Protocol Television (IPTV) is a system where a digital television service is delivered over an Internet Protocol network. also, IPTV is not a well-defined term and maybe a source of ambiguity and sometimes confusion.

IPTV is a television service where content can be displayed on a display with a set-top box that accesses channels, subscription services, on-demand, and other interactive multimedia services over a secure, end-to-end the operator managed broadband IP data network, with desired QoS to the public with a broadband Internet connection.

IPTV system may also include Internet services such as Web access and VOIP where it may be called Triple Play and is typically supplied by a broadband operator using the same infrastructure.

IPTV is not the Internet Video that simply allows users to watch videos over the Internet in a best-effort fashion.

IPTV technology offers revenue-generating opportunities for the Telecom and cable service providers.

For traditional telephone service providers, and also there are some providers, Triple Play is delivered using a combination of optical fiber and digital subscriber line (DSL) technologies to its residential base.

Cable television operators use a similar architecture called hybrid fiber-coaxial (HFC) to provide subscriber homes with broadband, but use the available coaxial cable rather than a twisted pair for the last mile transmission standard.

Subscriber homes can be in a residential environment, multi-dwelling units, or even in business offices.

From the service provider’s perspective, IPTV encompasses the acquisition, processing, and secure delivery of video content over an IP based networking infrastructure. The type of service providers involved in deploying free IPTV services ranges from cable and satellite TV carriers to large telephone companies and private network operators in different parts of the world.

IPTV is an evolving technology platform to provide television broadcasting services based on a wide range of rapidly advancing technologies. There are little information about implementation and services in operation for newcomers to observe. Caution and careful planning would mitigate the risk of failures.
