The Internet Protocol Television (IPTV) services are hitting up in the country. The latest to enter the IPTV players list is the telecom giant Bhatia Airtel. Besides Airtel, other telecom operators like MTNL, RCom and HFCL have already started IPTV services in various parts of the country.
In simple words, IPTV refers to TV delivered through broadband. The IPTV services which are still in nascent stages in the country are seen as a potential threat to the existing cable and satellite services.
Here's a quick primer on this convergence technology.

What is IPTV?
You are used to TV being delivered through traditional cable formats or the latest direct-to-home services. IPTV or Internet Protocol Television is different. Via IPTV, television content is viewed through technologies used for computer networks.
IPTV is a system where a digital television service is delivered using Internet Protocol (IP) over a network infrastructure, which includes delivery by a broadband connection.
The term 'IP' in its name stands for internet protocol and refers to a method of sending information over a secure, tightly managed network that results in a superior entertainment experience.
Building IPTV capability into a network allows a service provider to deliver voice and data as well. Companies providing IPTV services send television content to consumers through a broadband Net connection.

What all it can do
Simply put, IPTV makes your television experience more interactive and personalized. Interactivity is much easier to perform with IPTV than a normal cable, satellite or broadcast TV system.
Today, if a TV channel asks you to participate in game shows, you cannot use the remote to reply. With IPTV it is possible. IPTV can offer video on demand that allows you to request movies, TV shows and much more at your convenience
Also, instead of being bombarded with over a 100 channels (in case of cable TV), you will get content that you opt to receive with a much richer experience. Additionally, people who were separated geographically can watch a movie together, while chatting and exchanging files simultaneously.

What all a user needs
With IPTV, your TV will connect to a set-top box that decodes the IP video and converts it into standard television signals.
If a modem is added to the set-top box, it will provide a range of interactive services, including email, betting, games, shopping, information and even Internet access.
In India, as per IDC, the number of subscribers is likely to reach 966,000 subscribers by 2011 at a CAGR of 156.8 percent during the 2006-2011. IDC further expects 15.9 per cent of all residential broadband subscribers in India to use IPTV by the end of 2011, up from less than 1 per cent of all broadband subscribers in 2006.

How is it different from Internet TV
Internet protocol TV is different from Internet TV given that the user experience is bound to their living rooms and set-top boxes.
The quality, though, will be superior since the content is digital (unlike most of the traditional TV content).
IPTV, unlike Internet TV, is primarily a TV experience rather than a PC experience and is meant as an alternative to cable and satellite.

Triple play
IPTV can easily be bundled with broadband Internet service and VoIP services to offer what is popularly known as Triple Play.
The commercial bundling of IPTV, VoIP and Internet access is referred to as a Triple Play. This means with more players bringing IPTV services in India, the service is all set to pose a significant challenge to established cable and satellite services.
In US, Triple Play services are offered by cable television operators as well as by telecommunication operators. Triple Play implies high-speed Internet, television (Video on Demand or regular broadcasts) and telephone service over a single broadband connection. With wireless, it's called Quadruple Play and grouped services (triple and quadruple) are called multi-play.

Why this low penetration
Reasons for poor subscriber base of IPTV include lack of customer awareness about the benefits of the IPTV service, low broadband penetration, slow Internet access speeds and high set-top box cost.
One of the biggest reasons IPTV never took off in India was slow Internet connectivity. However, with faster broadband speed now there is every possibility that IPTV will take users by storm.
IPTV uses a two-way broadcast signal sent through the service provider’s backbone network and servers, allowing viewers to select content on demand, time shift (allows you to watch what you want to watch and when you want to watch), and take advantage of other interactive TV options.
To take advantage of this, viewers will need a broadband connection and a set-top-box to send and receive requests. Traditional cable TV has the capacity to deliver hundreds of channels simultaneously to each subscriber. This creates limitations on the number of channels offered and can contribute to bandwidth shortages and quality degradation. IPTV, by contrast, sends only one program at a time.
When a viewer changes the channel or selects a program, a new stream of content is transmitted from the provider's server directly to the viewer's set-top box.

How will businesses benefit from IPTV?
Companies can use IPTV to deliver television content over corporate LAN and business networks. The customized content delivery enabled by IPTV means reduced opportunities for theft of content.
Also, since the network is extremely secure, IPTV provides a good platform for businesses. In fact, as advertisers get better at understanding the behavior of consumers, they will have a significant opportunity to decrease the use of low-impact broadcast ads and increase the use of personalized ads that drive meaningful business results.
