Abstract:
Bringing TV experience to the mobile users opens up a new era in the evolution of
the mobile systems. Even if it started as a mere copying of the linear TV distribution
of today, the mobile systems technologies that can provide feedback channels from
every user enable new ways of enhancing the TV experience.
So besides just watching TV via broadcast or on demand, a whole myriad of
possibilities is enabled where the end-user can actively participate in the interactivity
sessions with the content provider and indirectly with other viewers. Further, more
sophisticated terminals enable pre-recording of the subscribed content to be
consumed at the user's convenience.
Today, 3G wireless systems offer a superior streaming capabilities for TV
distribution, either as unicast service (e.g. HSPA) or broadcast service (e.g. MBMS).
Actually, the best utilization of the resources is provided with a combination of the un
icast and broadcast services, where unicast part is used in areas with lower demand
and for offering basically unlimited number of channels, while broadcast part is used
as a capacity booster in areas where several users are interested in the same
content.
There are also alternative pure broadcast technologies like DVB-H, DMB, ISDB-T
and Media FLO that are gaining traction in different parts of the world but to provide
interactivity they must be integrated with some cellular system. That makes the
Mobile TV market segmented for the time being but the near future will show what
model is capable of gaining the largest momentum thus creating mass market for
Mobile TV.
Introduction:
Being able to watch television on the move from a wireless pocket-sized portable
screen has a value in many situations. In public transport vehicles, such as on the
train, on the bus, on the ferry, television is an entertaining way to spend your time.
The same goes for public spaces, like cafeterias, railway stations, bus stops,
entrance halls, queues in supermarkets and waiting rooms. There is also a need for
more mobility in private places: in the backyard at home, at the summer house, in a
taxi or a private car, the "TV-Anywhere" opportunity is interesting. Some family
members may even wish to have their own personal mobile television at home. In
fact, television is the main service missing from today´s mobile handsets that already
have voice, messaging, Internet browsing, radio, and still and video camera.
In addition to these possibilities for enriching the content experience for the mobile
end-user, mobile television offers a lot of business opportunities. For the
broadcaster, it provides a new way of reaching its audience while they are on the
move; for cellular operators it provides a cost-efficient way of delivering data to a
large number of recipients in a single DVB datacast; for the chip and equipment
manufacturer, it offers a new product.
However, it is clear that mobile television is only a supplement to the normal “dining
room” television. This is because this form of television offers the ultimate watching
quality, with crisp stereo or surround sound and a big-screen video picture. Watching
television is also very much a social activity – not a personal one.
Mobile analog television receivers have been on the market for years – especially in
Eastern Asia 1 . They have not been a huge success, which may be due to fact that
they do not have any new features over the normal television. The new interactive
television that is a part of digital television is a different thing however. It can be
argued that this interactivity is more natural for a user of a personal portable terminal
than for a normal television watcher on his/her sofa.
History Of Mobile TV:
Mumbai, November 28, 2011: HISTORY, the world’s leading factual entertainment
channel, which debuted its India edition on October 9th, 2011 and reached out to 45
mn viewers within a month of its launch, is now available on the Mobile Platform.
It will be available as Live Streaming as well as Video On Demand on GPRS
enabled mobile phones. To access the application, the user will have to send the
keyword “HISTORY” as an SMS to 51818. The user can chose to either view the
channel or key episodes from a particular show.
This service is available via Mobile TV across all leading mobile operators on such
as Vodafone, Airtel, Idea, Aircel, BSNL, MTNL, Reliance, Tata Docomo and Tata
Indicom. The subscription charges range from daily Rs. 7 to monthly Rs. 150. The
service will soon be available in other Indian languages as well.
Technology used In Mobile TV:
BBC was one of a handful of channels broadcasted during that demo, and while the idea itself was a natural evolution of market expectations, it was also, expectedly, a revolution for the cell phone industry.The Nokia N92 could beam full motion video at
30 frames / second, and supported about 4 hours of TV viewing on one charge. It basically had the equivalent of a TV tuner built into it that captured signals from compatible TV channels and stations.
The fundamental premise of a cell phone is that it works by picking up compatible radio signals. The idea was to build a cell phone that could pick up
signals in the frequency range of those allotted for broadcast televisions (VHF, UHF, etc.), hence making the concept of watching TV on your handheld a reality.
There were challenges to this, the biggest being that of transmission speeds. Typical
television broadcasting requires fast transmission speeds -- speeds much higher than what most of the current generation (2G) phones are capable of handling. That's where 3G technology comes in, offering broadband internet access to cell
phones and handheld devices at speeds ranging from 144 kbps to a blazing 2 MBPS. (That's the kind of speed you get over the cable and DSL lines connected to
your computer, and makes streaming audio/video from Web 2.0 sites possible.) In terms of hardware, Korean companies have been the traditional front runners in
implementing most of what Mobile TV technology is today. Two of their early implementations can be found in the form of the Samsung SCH-B250 and theLG
V9000 phones -- both of which were launched in 2006.
Currently, Mobile TV is a developing technology, and service providers like mobiTV,
Sprint TV, Vodafone and others are beefing up their systems to handle this significant demand.
There was a time when watching even videos stored on your mobile at decent frame rates and quality seemed like a big thing. But with advancements in processor /
memory technology and service throughput standards, Mobile TV is now the thing -- alongside WiFi Internet Phones.
You may have a satellite TV in your living room, but mobile TV is like have a satellite system right in your phone! -- The future of mobile entertainment, playing live in the
palm of your hands.

Application of Mobile TV:
There has been a great shift from traditional news platforms to online and mobile
news sources in the last couple of years.Having your dog bring you the freshly
delivered copy of the latest newspaper headlines seems like a memory from the past
in today's word where social networks such as Twitter can provide instant updates in
the event of breaking news.
The wider availability of nearly instantaneous micro newsfeeds has changed the very
notion of our news consumption. Younger generations and technological savvy
individuals are relying on news sources that are delivered in the form of community-
sourced information. These "news sources" are often supplied in the form of friends
status updates, blogs, trending topics and retweeted news headlines.
Consumers are also branching out from the one newspaper subscription model to
become better informed about current events.According to a report published by
Pew Internet on March 1, 92 percent of Americans use multiple platforms to get their
news during a normal day. Only seven percent turn to one single media platform to
read their news.
In the digital era, humans have turned to news platforms that let them customize
information according to their personal tastes. Twenty-eight percent of internet users
have created a personalized homepage that delivers news and information about
topics that interest them.
They also expect to be able to access news headlines from their mobile phones
when they are away from their computer. More than 30 percent of mobile phone
owners use their device to read news headlines.
"In this new multi-platform media environment, people's relationship to news is
becoming portable, personalized, and participatory," explained Pew Internet.The
study shows that people are becoming increasingly interested in participating in the
news. 37 percent of internet users surveyed said they had either contributed to the
creation of news, posted a comment about current events or helped spread news
headlines via social media sites.
"To a great extent, people's experience of news, especially on the internet, is
becoming a shared social experience as people swap links in emails, post news
stories on their social networking site feeds, highlight news stories in their Tweets,
and haggle over the meaning of events in discussion threads. For instance, more
than 8 in 10 online news consumers get or share links in emails," said Pew
Internet.2,259 US-based respondents took part in the survey from December 28,
2009 to January 19, 2010.
Future Scope Of Mobile TV:
As Korean companies bring new technologies to the U.S., broadcasters are
investigating simpler, cheaper ways to put shows on portable devices
Want to check out Friday Night Lights during your commute home? How about
Boston Legal? Good luck. Despite all the talk of watching live television on your
mobile phone or other portable device, the idea is more promise than reality these
days. What you can get, if you can get anything, is short, prerecorded video clips or
a handful of channels that your all-powerful wireless carrier has chosen for you.
All of that may be about to change. Two companies from Korea, land of the wireless
future, are bringing technology to the U.S. that will allow television stations to bypass
wireless carriers altogether and deliver programs directly to mobile phones. The
latest development on this front came on Apr. 3 when LG Electronics, in partnership
with Harris Corp. (HRS), unveiled new, inexpensive technology that allows stations
to zip local news and other video content to phones, portable video players, and in-
car entertainment systems within a 45-mile radius.
The announcement comes just as station owners are stepping up their efforts in
mobile television. A number of broadcasters are in the midst of negotiations to form a
coalition for mobile-TV technology. The talks, which have not been reported publicly,
are aimed at helping the services take off and could be announced as early as the
National Association of Broadcasters convention later this month. "We believe that
mobile TV is really the next killer application for broadcasters," says Brandon
Burgess, president and CEO of ION Media Networks, which is participating in the
negotiations. "There are a lot of broadcasters that are of the same mind."
The sudden emergence of direct-to-consumer broadcasting is a significant blow to
companies that have been advocating alternative approaches. They include
Qualcomm's (QCOM) MediaFlo, Crown Castle's (CCI) Modeo, and satellite radio
companies XM (XMSR) and Sirius (SIRI). MediaFlo, for example, has been working
with wireless carriers so that they can offer some television programming to their
customers.
Now, the Korean technology could bypass that approach, cutting out the wireless
carriers. "We don't need carrier partners," says Jay Adrick, vice-president at Harris'
broadcast communications division. Besides the LG and Harris announcement,
Samsung unveiled a similar technology earlier this year. TV broadcasters like the
idea that they will be able to keep control of their programming and advertising—
rather than becoming beholden to wireless operators. Burgess says that members of
the coalition, if it is formed, will decide on one technology standard, most likely LG's
or Samsung's. They will also determine whether to offer mobile TV for free, or to
charge a small fee for the service.
The potential alliance creates all sorts of problems for rivals. XM and Sirius have
been working for years on ways to deliver video to cars. Sirius is expected to finally
make video available in some 2008 model cars later this year. (To make matters
worse, the LG technology will allow TV stations to transmit radio signals—so XM and
Sirius may see more competition in their core radio business.)
