    Future Of IPTV In India

    Future Of IPTV In India

    Introduction Internet Protocol television (IPTV) is a system through which digital television

    service is delivered using the architecture and networking methods of the Internet Protocol

    Suite over a packet-switched network infrastructure, e.g., the Internet and broadband

    Internet access networks. Instead of being delivered through traditional radio frequency

    broadcast, satellite signal, and cable television (CATV) formats

    IPTV services may be classified into three main groups:

    Live television, with or without interactivity related to the current TV show;

    Time-shifted programming: catch-up TV (replays a TV show that was

    broadcast hours or days ago), s tart-over TV (replays the current TV show from

    its beginning);

    Video on demand (VOD): browse a catalog of videos, not related to TV


    IPTV is dist inguished from general Internet-based or web-based multimedia services by its

    on-going standardization process (e.g., European Telecommunications Standards

    Institute) and preferential deployment scenarios in subscriber-based telecommunications

    networks with high-speed access channels into end-user premises via set-top boxes or

    other customer-premises equipment.

    Many different definitions of IPTV have appeared, including elementary streams over IP

    networks, transport streams over IP networks and a number of proprietary systems.

    The official definition approved by the International Telecommunication Union focus group

    on IPTV (ITU-T FG IPTV) is as follows:

    "IPTV is defined as multimedia services such as television/video/audio/text/graphics/data

    delivered over IP based networks managed to provide the required level of quality of service

    and experience, security, interactivity and reliability."

    Another official and more detailed definition of IPTV is the one given by Alliance for

    Telecommunications Industry Solutions (ATIS) IPTV Exploratory Group on 2005:

    "IPTV is defined as the secure and reliable delivery to subscribers of entertainment video

    and related services. These services may inc lude, for example, Live TV, V ideo on Demand

    (VOD) and Interactive TV (it). These services are delivered across an access agnostic ,

    packet switched network that employs the IP protocol to transport the audio, video and

    control signals. In contrast to video over the public Internet, with IPTV deployments,

    network security and performance are tightly managed to ensure a superior entertainment

    experience, resulting in a compelling business environment for content providers,

    advertisers and customers alike."

    One definition for consumer IPTV is for single or multiple program transport streams

    (MPTS) which are sourced by the same network operator that owns or directly controls

    the "last mile" to the consumer's premises. This control over delivery enables a

    guaranteed quality and also allows the service provider to offer an enhanced userexperience such as better program guide, interactive services etc

    In commercial environments IPTV is widely deployed for distribution of live TV, video

    payout channels and Video on Demand (VOD) material across LAN or WAN IP network

    1/5/14 News: Future Of IPTV In India 2/15

    IPTV (Internet Protocol Television) delivers television programming to households via a

    broadband connection using Internet protocols. It requires a subscription and IPTV set-top

    box, and offers key advantages over existing TV cable and satellite technologies. IPTV is

    typically bundled with other services like Video on Demand (VOD), voice over IP (VOIP) or

    digital phone, and Web access, collectively referred to as Triple Play.

    Because IPTV arrives over telephone lines, telephone companies are in a prime position to

    offer IPTV services initially, but it is expected that other carriers will offer the technology in

    the future. IPTV promises more efficient streaming than present technologies, and

    therefore theoretically reduced prices to operators and subscribers alike. However, it also

    adds many advantages that may play into market pricing.

    One of the advantages of IPTV is the ability for digital video recorders to record multiple

    broadcasts at once. According to Alcatel, one leading provider, it will also be easier to find

    favorite programs by using "custom view guides." IPTV even allows for picture-in-picture

    viewing without the need for multiple tuners. You can watch one show, while using picture-

    in-picture to channel surf!

    IPTV viewers will have full control over functionality such as rewind, fast-forward, pause,

    and so on. Using a cell phone or PDA, a subscriber might even utilize remote

    programming for IPTV. For example, if a dinner function runs longer than expected; you

    don't have to miss your favorite program. Just call home and remotely set the IPTV box to

    record it.

    However, the real advantage of IPTV is that it uses Internet protocols to provide two-way

    communication for interactive television. One application might be in game shows in which

    the studio audience is asked to participate by helping a contestant choose between

    answers. IPTV opens the door to real-time participation from people watching at home.

    Another application would be the ability to turn on multiple angles of an event, such as a

    touchdown, and watch it from dual angles simultaneously using picture-in-picture viewing.

    IPTV is Internet Protocol Television. It is digital television delivered on TV (and not PC)

    through high speed internet (broadband) connection. In this service, channels are encoded

    in IP format and delivered to the TV through a set top box . IPTV service also includes

    video on demand, which is similar to watching video CDs/DVDs using a VCD/DVD player

    How does it work?

    IPTV converts a television signal into small packets of computer data like any other form

    of online traffic such as email or a web page. There are three main components of IPTV.

    TV and content head end, where the TV channels are received and encoded

    and also other content like videos which are sorted.

    The second component is delivery network, which is broadband and landlinenetwork provided by a telecom operators such as MTNL.

    The third component is set top box, which is required at the customer location.

    The packets are reassembled into programming by software in the set-top box.

    This box is connected between the operators broadband modern and

    customer TV

    What are the advantages and limitations 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 history while watching a

    game. They also may be able to schedule a recording of their favorite

    programmed when they are not home. With video on demand, they can browse

    an online movie catalogue and watch the movies instantly. Using standard

    networking protocols, IPTV promises lower costs for operators and users.

    Using set-top boxes with broadband internet connections, video can be

    streamed to households more efficiently than cable.

    However, since IPTV is based on internet protocol, it is sensitive to packet

    loss and delays if IPTV connection is not fast enough.

    When was IPTV service first used ever?In 1994, W orld News Now was the first

    television show to be broadcast over the internet, using the video conferencing

    software. Internet radio company AudioNet started the first continuous live web

    cast in January, 1998.

    When was it rolled out in India?Public sector operator Mahan agar Telephone

    Nigam (MTNL) is the first and only telcom in India providing IPTV services. It

    rolled out IPTV early this month in Mumbai and Delhi. The original 26 channelsit launched were free-to-air, while the new lineup includes premium

    subscription channels. It has not yet announced tariff plans, which will vary

    depending on the number of channels a user subscribes to and the use of

    premium services.Internet Protocol Television (IPTV) is rapidly being deployed

    as a compliment service to existing distribution technologies

    Why IPTV?

    Traces the changes in Internet Protocol Television since the mid-1990s and

    examines what IPTV means today. The author analyzes what delivery of TV

    over an IP network means, both in terms of possibilities for new services, and

    in terms of the impact on the network and how it has to be managed. In

    addition, Why IPTV? Helps you understand how introducing IPTV into the Web

    2.0 world will impact the new services. It looks at the current trends in the

    consumer electronics industry as well as the network industry, and describes

    how the new technology can enhance and extend the existing business

    models in the TV industry, particularly in advertising; and also how it creates

    new possibilities, for instance, through personalization.

    Interactivity, Technologies, Services:

    Provides an accessible introduction to IPTV.

    Covers the technology to build IPTV systems, and shows what lies

    beyond traditional business models and existing distribution


    Considers how IPTV technologies can exploit and change the

    current trends in consumer electronics and network industry

    The computer has invaded almost all sectors of our lives. No place

    or situation today is bereft of the use of computers. The computer

    technology invaded the idiot box in our living room some time ago

    with digitalization in the form of direct-to-home (DTH) high quality

    digital pictures. Now, another computer technology has affected

    the idiot box in a new way. This technology proposes the

    discarding of antennas, cable TV wires, and the DTH set top box to

    bring to you television viewing through the internet.

    This technology is known as the Internet Protocol Television (IPTV)

    technology. IPTV delivers digital television service through a

    system that delivers broadband connection to our homes. IPTV is

    an acronym for Internet Protocol TV. It essentially is a technology

    that delivers video or TV broadcasts over the Internet. Instead of

    receiving television or video over the broadcast waves, cable lines

    or through a satellite TV service, your TV is hooked directly into a

    broadband Internet router and receives digital signal directly over

    the Internet.Many analysts have stated that IPTV is definitely the

    trend for the future of television broadcasts. Many broadband

    operators, telephone companies and cable companies that already

    pipe in broadband Internet to homes can easily add this service


    There are many advantages of IPTV over current digital or over the

    air broadcast TV signals; here are a few of them. Integration

    Integration can be a great way for many companies to offer several

    services in one integrated package. For instance, IPTV can also be

    packaged with normal broadband Internet as well as Void (Voice

    over Internet Protocol). All these services can be over one line sent

    directly to the consumer. This means that costs can be reduced

    and the consumer only has to deal with one provider instead of

    possibly three, making it more convenient. Switched IP Most home

    owners don't realize that cable TV broadcasters and Satellite TV

    broadcasters generally send all television signals at one time and

    then the consumer chooses which signal to show on the television

    set. This means that lots of bandwidth is used unnecessarily. With

    switched IP (IPTV uses switched IP technology), the entire

    process is more efficient. All the TV data is held in a center

    location and only the channel that the consumer at home chooses

    is piped in. This means much more bandwidth for either better

    quality broadcasts or the ability to add much more data choices

    due to the fact that bandwidth is no longer such a big issue


    Interactivity is much easier to perform with IPTV than a normal

    cable, satellite or broadcast TV system. Because IPTV is delivered

    over the Internet where the consumer already has a modem in

    place, it is extremely easy for data to move from the TV company

    to the house, as well as data moving easily from the house back to

    the TV company. There will surely be many innovations on how tobest interact between the consumer and TV company via

    television. Some ways interactive TV is already used is to

    purchase products directly from your TV set, such as buying items

    seen on a commercial or even ordering pizza. Another way that

    interactive TV can be used is by people requesting more

    information from their TV set on a program that they watched such

    1/5/14 News: Future Of IPTV In India 6/15

    the United States is projected to see a larger movement

    toward IPTV deployments, industry experts say, as

    more residences transition from cable to wireless.

    In Asian markets, such as Japan and Taiwan, IPTV is

    pushing home networking like you would never believe,

    said David Thompson, product marketing director of

    Taiwan-based Zexel, which also has a headquarters in

    Anaheim, Calif. In North America it is now very

    common for most homes to have a wireless router,

    IPTV technology is now changing the way many are

    viewing video media. Offering many benefits oversatellite or traditional cable broadcast methods; IPTV

    utilizes the internet for the streaming of its content. The

    resulting media can be customized to suit a number of

    applications. For example, hospitals, schools, and

    hotels can benefit in a big way from the capabilities this

    service provides. The IPTV SolutionWhether you are

    looking to add interactivity, broadcast to a large number

    of people without added cost, or want to increase

    picture quality and video choices, this new technology

    can provide a solution for all of those demands and


    In Hotels

    For hotels, the benefits of IPTV technology are

    tremendous. Depending on what you wish to offer your

    guests, you can provide on-demand and live access to

    movies, television shows, and even games. You have

    the option to provide these free of charge to every room

    or else to charge based on each selection. For hotel

    guests, having on-demand capabilities is much more

    convenient than traditional television as they are

    constantly in and out of their rooms, making it difficult

    to watch a particular program at a set time. You will

    also have the ability to broadcast hotel information as

    well as giving guests the facility to view their billing

    details via the television.

    In Schools

    IPTV technology can also be useful in school settingsas well. Instead of basic morning announcements over

    the traditional P.A. system, IPTV makes it possible to

    broadcast video content that reaches every room

    throughout the school. This is also useful for sharing

    educational video content with many classrooms at

    once, without the need to shuffle around videos and

    DVDs. Instead, teachers can have access to a variety

    of educational programs whenever they need them. This

    technology also provides a number of options for

    interactivity that will more likely than not be creatively

    implement into many schools in the future.

    In Hospitals

    Another application for this technology is in hospitals.With a large number of patients and rooms, it can be

    difficult to provide a variety of programming to suit

    everyone's tastes. As patients are typically confined to

    their beds for a long period of time, television and

    movies provides a much-needed distraction through

    entertainment. Although conventional cable systems

    are not easily streamed to such a large number of

    rooms, IPTV makes this possible at a very low cost,

    without the need for extensive, invasive wiring running

    throughout the building. With its increasingly growing

    variety of applications, IPTV technology certainly

    appears to be the television for the future. ave an

    effective security infrastructure that can use the

    technology and the law towards achieving the objective

    of securing the information assets of the country

    Void. This involves using your Internet connection

    instead of your traditional phone line to make calls. It

    had many advantages and disadvantages over

    traditional phone systems. The technology was just

    getting out the door when the article was written, and is

    now readily available to nearly everyone. It still hasnt

    caught on as much as I thought it would. It appears

    most people are just using cell phones and ditching

    their household phone. But now we are seeing another

    common household feature moving to the Internet.

    What it is? The name speaks for itself: IPTV, TV overthe Internet. Its a rather simple idea, though it's much

    more difficult than it seems, as I will explain later.

    Faster computers and quicker Internet connections are

    making IPTV more of an option. As the technology

    advances, we will see more IPTV with more channels

    and HD support as well. Chances are that you have

    probably even used IPTV without even knowing it. IPTV

    first hit the Internet in 1994, right as the masses were

    starting to get online. Back then it wasnt as abundant

    as it is now, and most people probably never even knew

    about it. Fast forward to 2008, and we have many

    different types of IPTV, from ESPNs video highlights on

    their home page to IPTV on your cell phone. IPTV has

    really taken off and is still on a steep rise.

    ABC was the first to use IPTV in 1994, and continues

    to lead the way with IPTV. Their first show needed a

    fast connection, special video conferencing software,

    and had to be online during the time it was being aired.

    Now ABC has their shows in full episodes online for

    anyone to stream from their browser at any time. No

    longer are you tied to the time the TV show airs to

    catch it.

    An IPTV deployment can involve a variety of things

    depending on the system architecture used. Generally,

    however, it involves new set-top boxes, usually MPEG-

    4, some new headed equipment and a good deal of

    systems integration. It also involves choosingmiddleware, conditional access/digital rights

    management system and a variety of other related

    applications that impact security, customer satisfaction

    and system management.

    A key challenge for the majority of IPTV service

    providers, especially with a telecommunications

    heritage, can be the lack of media related expertise.

    Components of the IPTV architecture such as

    conditional access, DRM, and middleware require

    media specific systems integration and network

    management capabilities. Smaller telcom and even

    rural cable companies that have yet to upgrade to a

    digital system will have to climb a steep learning curveto provide quality IPTV services. Strategic partnerships

    with systems integrators that have installed head end

    equipment and software can ease the deployment of

    IPTV. Larger telcom should also consider these types

    of partnerships as they move forward in their IPTV roll


    Program content acquisition can also pose a challenge

    for an IPTV service provider that has no experience

    working with media companies. Established

    broadcasters have many decades of experience

    commissioning and delivering content.

    Telecommunication operators have none. The success

    of telecom operators in the IPTV space can rely heavily

    on their relationships with various content providers and

    programmers. Bargaining power tends be a larger issue

    for smaller operators than to a Verizon or AT&T, but the

    ability to find new and innovative content can be

    arduous for any sized company One area where telcom

    are attempting to differentiate them from incumbent

    Moss is with niche programming (often termed the long

    tail in industry parlance). Demand for this type of

    programming is evidenced by the success of video file

    sharing, which largely consists of long tail content. The

    ability for IPTV providers to acquire and use niche or

    long tail programming may become a competitive


    Convergence is now here with mobile, data, voice and

    video all going over Internet infrastructure. In particular

    the promise of TV delivered via IP is gaining momentum

    globally the more the Internet merges with consumer

    electronics, especially televisions. But plenty ofchallenges remain, not the least of which is the pending

    depletion of the IPv4 address space. Experts predict

    IPv4 addresses will be exhausted as early as 2010.

    That's why the move is underway to the IPv6 protocol,

    which provides significantly more address space for

    devices. The move to IPv6 has been slow around the

    globe, with a few exceptions. One of them is in Japan,

    where deployment of IPv6 by telcom NTT could provide

    a blueprint for carriers preparing for the rise of IPTV.

    "NTT Pala Hiker TV is the first large scale commercially

    successful IPTV over IPv6 service," said Cody

    Chrisman, NTT America's director of product

    engineering. "It has 76 channels of standard and high

    definition TV over the network, over 10, 00 video on

    demand tiles and 13,000 titles in their Karaoke service."

    NTT Pala is a Japanese Internet service provider

    operated by NTT. The company's Hiker TV deployment

    is getting a demonstration at the Consumer Electronics

    Show in Las Vegas this week as an example of IPv6

    put to practical use. The Hiker TV deployment runs on

    top of NTT's next generation IPv6 network, which

    Chrisman noted delivers Internet service to 10 million

    Japanese subscribers. The Hiker TV service currently

    has penetration in the hundreds of thousands of users.

    (The term Hiker is Japanese for light and refers to the

    fiber optic cable to the home that carries the service.)

    Consumers in Japan can buy set-top boxes that are

    IPv6 enabled for Hiker. As well, Chrisman noted thatthere are also Hiker-ready TV sets in Japan from

    Toshiba that integrate the set-top box capabilities

    directly into the TV. This happens with Ethernet port

    that plugs directly into users' TVs. Chrisman says the

    need for IPv6 for IPTV delivery is obvious, given that the

    IPv4 protocol is running out of room. By building out an

    IPv6 deployment, NTT has more scalability to grow the

    service and its functionality over time. In particular, one

    thing that a unique IPv6 address will allow Hiker TV

    consumers is end to end address transparency.

    In North America and globally, Network Address

    Translation (NAT) is used to take a public IPv4 address

    and the provide a private local addresses, such that onepublic IP address could have many users and uses.

    With IPv6 and its abundance of address space, NAT is

    no longer required, which Chrisman argued enables

    service providers to have a cleaner network architecture

    that doesn't have to deal with NAT and some of the

    potential connectivity problems that it poses. IPv6 with

    its unique IP addresses for all also enables end to

    security without NAT interference.

    While the Hiker TV service is delivered over IPv6, it

    does have compatibility with IPv4 based Internet

    services as well. Chrisman explained that NTT tunnels

    IPv4 addresses over the IPv6 backbone so users can

    access IPv4 based content. With the advent of support

    for HD (High Definition) resolutions on decoders, and

    System-on-Chip (Sock) integrated decoders rather than

    more cumbersome software solutions, the market had

    begin to adapt IPTV-based interactive video services.

    Today these services include Void (Video on Demand)

    and EPG (Electronic Program Guide). But with

    emerging next-generation networks and technologies,

    1/5/14 News: Future Of IPTV In India 9/15

    the ground is ripe for introduction of full interactive video

    services to residential and business customers based

    on IPTV and IP set-top-box models

    TELCO TV & IPTV Current Status

    As consumers continue to search for complete service

    packages that include voice, video and data, they will

    naturally begin to conider telcom TV. In addition,telecom operators with significant broadband

    deployments seeking new sources to generate revenue

    will find IPTV-based telcom TV a natural extension of

    current network infrastructure. IPTV is a system where

    digital television service is delivered using IP network

    infrastructure. In the residential market, IPTV is often

    provided in conjunction with Video-on-Demand (Void)

    and may be bundled with other Internet services, such

    as Web access and Void. The commercial bundling of

    IPTV, Void and Internet access is referred to as "Triple

    Play." IPTV is delivered to residential subscribers using

    an IP set-top-box (IP STB). The development and

    delivery of value-added services is key to the long-term

    viability of the telcom TV (IPTV) business model. These

    services will be built upon IP Stubs that deliver full

    interactivity. Todays IP Stubs allow only a limited range

    of interactive services. These include Void (Video-on-

    Demand), mentioned before, PVR (Personal Video

    Recorders) and EPG (Electronic Program Guide).

    These services are either already available, or in late

    stages of development. Therefore, IP STB

    manufacturers have very little to work with to

    differentiate their IP STB offerings from the competition.

    This is where the technology that enables

    manufacturers to turn conventional IP Stubs into full-

    fledged, live interactive video service platforms comes

    in. Revisions technology plays an important role in this

    trend and offers all the technology and expertise

    needed to develop live face-to-face interactive videoservices on STB platforms. IP STB of the Future

    Revisions vision is to transform the IP STB into a true,

    interactive and rich communication center the

    households communication epicenter. This can be

    achieved by adding video conferencing technologies to

    the IP STB itself, which enables a variety of new ways

    to use the IP STB. According to recent market research

    published by Frost & Sullivan (October 2006): "The

    adoption of common standards for IPTV interoperability

    is crucial if there is to be mass adoption of interactive

    visual communications in the business and consumer


    The implementation of open standards developed byvideo conferencing offers the means of connecting

    these disparate islands of users in a manner similar to

    that of the IM federation, which is already successfully

    uniting the IM population." Not only should interactivity

    not be limited to content; live interaction between

    people is a springboard for an entirely new paradigm of

    1/5/14 News: Future Of IPTV In India 10/15

    communication. Internet Protocol Television is the

    newest technology on the block. It is often referred to

    IPTV, which is television content broadcast through the

    computer networks such as internet. Instead of the

    traditional cable and broadcast formats, the viewers can

    now watch television on the internet. The entire process

    involves receiving and sending data by the means of the

    packets of information. IPTV, pretty much uses the

    same technology, although there are some minor

    differences. Along with the packet conveyance

    method, including the internet, IPTV is broadcast

    through closed, separate networks, which are againdependent on the internet. This would provide better

    speed, quality and usability as compared to satellite TV

    or analog cable. Unlike the cable or satellite TV,

    television on internet would provide only one single

    channel that you pick from the programming guide,

    which results in a faster and an efficient TV watching

    experience. Due to this enhanced efficiency, IPTV is

    able to provide a selection of programming features to

    the audiences. A few of these features include the

    onscreen caller id, the programming guides and the

    hard-drive recording. Television on internet is convenient

    and reliable. The sound quality is superior and with the

    above mentioned interactive features, IPTV is becoming

    exceedingly popular all across the world. In order to

    maintain the uniformity of the broadcasts amongst the

    providers, the channel broadcasts are going completely

    digital, as the technologies continue to improve.

    Furthermore, a lot of telecommunication carriers plan

    on accelerating the deployment of IPTV services.

    There are various IPTV forums which would allow you to

    discuss the open standards of these technology

    specifications. Internet is now just not the source of

    information. But now it has also become a medium of

    entertainment. Internet television is one of the offering

    that internet delivers today. As the name suggests

    internet television is a television service distributed via

    internet medium. In simple terms viewers need to be

    sitting in front of TV, holding the remote if they want tocatch your favorite show or sports. Instead they can

    also watch it on their laptop or PC if it is connected to

    the internet

    IPTV is more Beneficial In terms Of Business:

    Internet Protocol Television, or IPTV, is an exciting new

    technology that is helping to create a far better means

    of watching television. However, using IPTV for

    business is without doubt going to change the way that

    many businesses operate.

    IPTV is NOT online videos or internet shows. This can

    be extremely low in quality and require extensive

    buffering. This service works the same way as VOIP

    (Voice over Internet Protocol) phone services, andconnects people so that they have a 2-way connection

    with television shows and networks. When live TV is on,

    users can communicate with show hosts and

    audiences through the 2-way communication.

    This technology has a large number of uses. Generally

    speaking, this technology is relatively new and is

    designed for consumers, but business applications are

    multiplied extensively. For example, there is a plan in

    the works to release a private IPTV network within

    McDonald's locations throughout Italy, allowing

    customers to see unique video material, which includes

    pre-recorded commercials, live sports, and other

    shows. Hotel and hospitality services are going to see

    the most use from this technology because it gives

    them a chance to customize the content that they offer

    to their guests. However, this service will be highly used

    across the entire business world.

    IPTV also gives people the chance to create a private

    network of television entertainment and content that is

  • 8/13/2019 News_ Future of IPTV in India


    1/5/14 News: Future Of IPTV In India 11/15

    digital quality and doesn't have the bugs and buffering

    issues of internet videos and web-based television. If it

    helps you to compare this service to something, think

    in terms of the closed-circuit televisions that we often

    see used in schools and offices to limit the

    broadcasting that is seen or to show advertisements

    and dedicated television content as needed. Using the

    internet-bandwidth connection provides excellent quality

    images and much better production than analogue and

    digital television utilizing cable services.

    IPTV technology is the latest in innovations for getting

    the daily communications that people thrive on andenjoy. You may have heard of the ever-popular Voice

    over Internet Protocol (Void) phone service from

    companies like Voyage. Well, to make this easy to

    understand, IPTV is the same, only with television over

    internet protocol, instead of voice. Ultimately, TV can

    be watched anywhere through a broadband connection

    with IPTV, which makes it a very popular choice for

    those looking for the latest and greatest in new

    technology. Telecommunications companies are

    looking for new revenue, and they have found it with this


    IPTV technology is based on a system that is much

    like cable. There is the need for a computer or a set-top

    box of sorts so that the images can be transmitted,

    decoded, and then sent out to the television in a format

    that can show them properly on the screen. This type of

    broadcasting can be done by a simple broadcast or

    multicast if someone is trying to get a channel out to

    everyone. However, it can also be done on an 'on

    demand' basis, where people are able to stream

    material to just one or two subscribers who have

    requested the show or material in question

    Maintaining the Technology

    There is a lot of work and technology that goes into maintaining

    IPTV technology. Streaming over broadband needs to be done

    efficiently and in a format that will allow for the seamless transition

    of the data that is being sent. The process for using IPTV involves a

    lot of encoding, splitting, and distributing efficiently. The provider

    end is very complicated, but for customers it is a simple tool to

    use. Channel selection for IPTV is done via a membership known

    as IPGMP, or IP Group Membership Protocol. Due to the data

    transmission, this makes sending multiple channel signals and

    changing channels much simpler than it might be otherwise.

    IPTV is not only online videos or internet shows. This can be

    extremely low in quality and require extensive buffering. This

    service works the same way as VOIP (Voice over Internet Protocol)

    phone services, and connects people so that they have a 2-way

    connection with television shows and networks. When live TV ison, users can communicate with show hosts and audiences

    through the 2-way communication.

    This technology has a large number of uses. Generally speaking,

    this technology is relatively new and is designed for consumers,

    but business applications are multiplied extensively. For example,

    there is a plan in the works to release a private IPTV network within

    McDonald's locations throughout Italy, allowing customers to see

    unique video material, which includes pre-recorded commercials,

    live sports, and other shows. Hotel and hospitality services are

    going to see the most use from this technology because it gives

    them a chance to customize the content that they offer to their

    guests. However, this service will be highly used across the entire

    business world.

    IPTV also gives people the chance to create a private network of

    television entertainment and content that is digital quality and

    doesn't have the bugs and buffering issues of internet videos and

    web-based television. If it helps you to compare this service to

    something, think in terms of the closed-circuit televisions that we

    often see used in schools and offices to limit the broadcasting that

    is seen or to show advertisements and dedicated television content

    as needed. Using the internet-bandwidth connection allows for

    higher quality images and better production than analogue and

    digital television through cable services

    This particular product is not quite at its peak yet, but is growing in

    popularity. If you are looking for a better way to broadcast or

    provide television to customers or employees, this might be a great

    solution. The technology isn't going to be applicable to every

    business, but it has many different applications that users can

    appreciate in a business setting. If you have an interest in thelatest technology or if you currently have a VOIP provider for your

    phone service, you may well want to consider IPTV as an

    alternative to a standard satellite provider or cable network to get

    improved quality, better customization, and plenty of other benefits

    for your business needs.

    IPTV network systems can be individually custom-built to fulfill the

    unique demands of the hospitality and hotel market. Whether it's a

    modest boutique guest house, luxury 5 star hotels or a sports

    stadium, IPTV companies can supply the complete range of tools

    you need to offer a complete IPTV hospitality service to your


    What's the Advantage of IPTV in Hotels and Hospitality?

    IPTV is what your valued hotel guests will expect and demand. It is

    the future of any TV distribution in a hotel and with IPTV technology

    in place, you will have a wealth of benefits: Distribute free to view

    and subscription satellite or terrestrial TV signals throughout your

    computer network to bars, guest bedrooms, public areas or

    conference facilities within a hotel Offer extensive set of local and

    foreign language TV and radio channel, in-house advertising

    AT&T and Verizon have reported clear subscription increases in

    their IPTV based services with AT&T reaching about 2.5 million

    subscribers vis--vis Verizons 3.2 million mark. This means that

    AT&T and Verizon have about 5% of the sum of Comcast cable

    subscribers which are in the range of 20 million but the IPTV

    subscription number is growing, and fast.

    Many would agree that the North America IPTV services market is

    still in embryonic form compared with, in sheer numbers, the very

    popular, robust, and well proven and tradition cable based TV

    service. On the other hand the latest information clearly shows that

    a number of major operators, especially those with little or no

    underlying cable network, are clearly favoring IPTV deployments.

    With the fast growth in internet based technologies and general

    trend towards converged and glued services, one expects that

    internet based broadband services will grow. In addition, DSL

    upgrades will eventually be replaced by longer distance VDSL

    systems and fiber, allowing extraordinary bandwidths and speeds

    at reasonable prices.

    On the other hand, Europe is slowly but surely bridging the digital

    divide and implementing full (and free) broadband digital television

    services, in addition to the assortment of existing satellite

    television services, while releasing the analog spectrum for other


    IPTV and the Digital Divide

    Indeed competition for viewer attention and broadband multimedia

    services will continue to increase. The key advantage of IPTV

    based services perhaps, is that fact that the user can adapt thedesired service to fit his or her schedule, with minimal effort,

    instead of trying to accommodate ones schedule to fit broadcast


    Interactivity is of course another key component, missing from

    other services especially broadcast related ones.

    In addition, the fact that IPTV is based on internet connectivity

    means that the services and related technology can be interfaced

    with other subsystems such as the IP Multimedia Subsystem.

    Internet Protocol version 4 the fourth iteration of the Internet

    Protocol (IP), is one of standard internet work-layer protocol used

    and the first version of the protocol to be widely deployed on the

    Internet. Going through the history during the early 1990s, it was

    clear that IPv4 was not a long-term protocol.

    Its design did not anticipate a number of requirements that turned

    out to be crucial. Such requirements not only pertained to the

    proliferation of devices, but also the need for additional security,

    simpler configuration and better prioritization of some services,

    such as real-time services (often referred to as Quality of Service


    IPv6 multicast was adopted for the first time in the world in a

    commercial IP TV service started on July 28, 2004. The 4th MEDIA

    Service aims to attract 200,000 subscribers in the first year. It will

    probably become the largest consumer IPv6 service soon.

    In Japan, there had already been two IP TV services available:

    BBTV by Yahoo! BB and Hiker plus TV by KDDI. A major

    difference of 4th MEDIA with them in business model is that 4th

    MEDIA is rather a horizontal business alliance.

    4th MEDIA Service is a broadcasting and VOD service started by

    Pala Networks, an NTT East group ISP business, in an alliance

    with Online TV, a company established by Jupiter Programming

    and others for this service. The business is supported by several

    ISPs, including @nifty, BIGLOBE, and hi-ho, as well as Pala, for

    user supports and fee collection

    Pala Networks has provided IP phone operation for other ISPs. The

    company started video service in a similar scheme. The fact that

    4th MEDIA broadcasting uses IPv6 multicast means that each set

    top box gets directly connected to IPv6. The deployment of a new

    architecture becomes a need as well as a necessity. The transition

    to IPv6 holds the future of the internet infrastructure. IPV6! Theprotocol is a robust technology designed as a successor to IP

    version 4 (IPv4), the predominant protocol in use today. The

    changes from IPv4 to IPv6 are primarily in the areas of expanded

    addressing capabilities; header format simplification; improved

    support for extensions and options; flow labeling capability; and

    consolidated authentication and privacy capabilities.

    The kind of communication that will be enabled by the advent of

    IPv6 will be particularly useful in the embedded systems arena, as

    millions of new devices take advantage of Internet connectivity.

    Although IPv6 has been around for several years, there continues

    to be a debate about its value. But there are many ways in which

    IPv4 is not working, and there are good amount of reasons why the

    migration of IPv6 is not only desirable, but necessary. Some of the

    areas include reducing address space, Internet Security, Quality of

    Service, auto configuration, wireless, IMAX the list are endless.

    One of the important aspects of implementation IPv6 is that it will

    remove any concern about the limitation of IP addresses. IPv6 uses

    128-bit addresses, versus the 32-bit addresses used by IPv4.

    Compared to the total possible number of IPv4 addresses, 4.29

    billion, IPv6 provides nearly 600 quadrillion addresses for every

    square millimeter on earth. That's 6x1023 addresses for every

    square meter of the earth's surface.

    When each device has its own unique global IP address and NAT

    is no longer necessary, peer-to-peer communication will become

    much easier. Two devices will be able to establish direct

    communication without the need to translate between global and

    private addresses. Two-way applications such as IP telephony,

    video conferencing and gaming will be much simpler to develop.

    Routing tables will become far less complex, which will enable

    higher performance for Internet traffic and more bandwidth foradditional communication.

    The Internet is expanding into many new areas such as mobile

    Internet, IPTV and other IP embedded services which require more

    and more new IP addresses every day. The growth of IP based

    services and devices will stretch the current Internet protocol

    beyond breaking point because in a few years, there will be no

    more Imps available.

    The main reason (and benefit) for IPv6 initial deployment is the

    vastly increased address space compared to its predecessor IPv4.

    To get a general idea, IPv4 currently supports approximately 232

    which equal about 4.3 billion IP addresses. If you compare it to the

    number of persons around the globe, it won't even be enough to

    assign one single IP to every living person. IPv6, however, supports

    2128 addresses. This is approximately 5x1028 for each of the 6.5

    billion people alive today or the possibility to add an address to

    each atom in the average person's body. I think that should be

    enough for everyone.

    Unfortunately, at the moment, the Internet is still dominated by

    IPv4 and very few of the ISPs offer IPv6 connectivity. So, in order to

    test the v6 protocol, you will have to create an IPv6-in-IPv4 tunnel

    that will use the existing IPv4 infrastructure to encapsulate and

    carry IPv6 packets. Such tunnels are widely deployed today. To

    create a 6to4 tunnel, you will have to search on your favorite engine

    for "ipv6 tunnel broker" and pick the one closest to you (evidently,

    for low pings and high connectivity)
