What is IPTV and how does it work

Internet Protocol Television (IPTV) is a service that provides live and on-demand television programs and other video content through TCP/IP networks. It’s merely a technical term for streaming via the internet. This IPTV service is contrasted majorly to the traditional TV programming delivered mainly through cables and satellite signals.

IPTV enables you to continuously stream source media via an internet connection, which more efficient compared to the traditional media. The content of IPTV can be delivered over a dedicated/private or managed network and the public internet. The network operator can ensure the quality and reliability of the service by controlling the video traffic.

There are many different forms of IPTV which include online-only service providers like Sling and direct tv; television network apps like FOX now, BBC iPlayer; online-only TV channels such as Cheddar TV, Websites offering free live TV, plugins for apps such as Plex and Kodi, and third party IPTV subscription services. Major TV providers like Netflix, Amazon, and NOW TV, have adopted the service already.

How does IPTV work?

IPTV uses digital signals that are transported over the internet. This forgoes the traditional broadcasting methods of TV programs using radio waves through analog signals carried over the air. There are several steps that a TV program has to go through before it can be digitally aired via IPTV when streaming: Program storage, Program streaming, and Program viewing.

IPTV service sends only one program at a time in contrast to the traditional TV, where all the programs are broadcasted simultaneously, and you have to select a given program by changing the channel. When a viewer clicks a television program or request video, videos from various servers are divided into data packets and sent through the internet. The video servers use fiber optic cables to transmit the programs to existing households through an internet connection, while requests are typically sent out and show sent back.

The content remains on the network of the service provider, and only the selected program is sent to the residence of the customer. A new stream is transmitted directly to the viewers when, in any case, the viewers change a channel. IPTV requires a set-top box or a customer premises device just like the cable TV. It primarily uses IGMP (Internet Group Management Protocol) for the live TV broadcasts and (RTSP) real-time streaming protocol for on-demand programs.
