IPTV (Internet Protocol Television) is a system where digital television services are delivered over the internet by using Internet Protocol. The video channels and programs are delivered to the television sets through a broadband connection, instead of being delivered through the conventional cable or broadcast formats. The video streams are encoded into a series of internet protocol packets and then carried out through the public internet means which can be received by anyone by having a set-top box and a subscription for the service. IPTV is generally provided bundled with the VoIP and the internet access which is referred as “Triple Play” service. So this service is a complete package that allows customers to watch TV, browser the internet and making a long distance calls using the VoIP. This service is typically provided by a service provider using a closed network infrastructure.
IPTV services may be classified into three main groups:
- Live television, with or without interactivity related to the current TV show;
- Time-shifted television: catch-up TV (replays a TV show that was broadcast hours or days ago), start-over TV (replays the current TV show from its beginning);
- Video on demand (VOD): browse a catalog of videos, not related to TV programming.
How does it work?
Internet TV, in simple terms, is video and audio delivered over an Internet connection. It’s also known as Internet protocol television, or IPTV. You can watch Internet TV on a computer screen, a television screen (through a set-top box) or a mobile device like a cell phone or an iPod.
It’s almost the same as getting television through an antenna or a series of cable wires — the difference is that information is sent over the Internet as data. At the same time, you can find even more variety on Internet TV than cable TV. Along with many of the same shows you find on the big networks, many Web sites offer independently produced programs targeted toward people with specific interests. If you wanted to watch a show on vegetarian cooking, for example, you could probably find it more easily over the Internet than on regular TV.
Because many sites offer on-demand services, you don’t have to keep track of scheduling. For sites using webcasting or real-time streaming video, though, live broadcasting is still an option.
Internet TV is relatively new – there are lots of different ways to get it, and quality, content and costs can vary greatly. Shows can be high-quality, professionally produced material, while others might remind you of Wayne and Garth broadcasting “Wayne’s World” from their basement. Traditional TV networks are also easing into the technology and experimenting with different formats.
What are the advantages of IPTV?
The quality of digital video and audio is much better compared with the traditional analogue TV. With additional features, it can become interactive. For example, viewers may be able to look up a player’s history while watching a game. They also may be able to schedule a recording of their favourite programme when they are not home. With video on demand, they can browse an online movie catalogue and watch the movies instantly.
Because IPTV uses standard networking protocols, it promises lower costs for operators and lower prices for users. Using set-top boxes with broadband internet connections, video can be streamed to households more efficiently than cable.
What are the limitations of IPTV?
Because it is based on internet protocol, it is sensitive to packet loss and delays if the IPTV connection is not fast enough. Internet Protocol Television always wants stable internet , streams with high resulution needs a very fast internet. This is the thing that we can call a disaventage of iptv.
Where can i install the IPTV ?
Because the iptv works thought internet, it allows you to connect with it in different ways. IPTV it’s very simple to watch on any device. It can be installed in Smart TV ( LG & Sasmung), Phone, Tablet, Laptop, IPTV AndroidBoxes, MAG boxes etc.
