2. The DTH
DTH stands for Direct-To-Home television.
“ The reception of satellite programmes with a personal dish
in an individual home.”
3. DTH services in India
Idea was 1st proposed in 1996, but they did not pass approval because there
were concerns over national security and a cultural invasion.
Govt. putted a ban 1997 when the Rupert Murdoch-owned Indian Sky
Broadcasting (ISkyB) was about to launch its DTH services in India.
Passed approval in 2000 but the signals can be transmitted through Indian
satellite.
Cost and validity period of DTH license.
Law imposed on DTH service providers(51:49).
Share of DTH Services in Indian market in India is less then 5%.

5. DTH MPEG Technology
The Moving Picture Experts Group (MPEG) was formed by the ISO to set standards
for audio and video compression and transmission.
• MPEG-2 is widely used as the format of digital television signals that are
broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV
systems. While MPEG-2 is the core of most digital television and DVD formats.
• Provider - Tata Sky.
• MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related
standards, adding new features such as (extended) VRML support for 3D
rendering, object-oriented composite files (including audio, video and VRML
objects), support for externally-specified Digital Rights Management and various
types of interactivity. AAC (Advanced Audio Coding) was standardized as an
adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued.
• Provider - Videocon d2h , BigTV , Airtel , SunDirect , DishTV )

7. Working of DTH.
A DTH network consists of a broadcasting
centre, satellites, encoders, multiplexers, modulators and
DTH receivers( STB).
8. Component of DTH system
• Programming sources are simply the channels that provide programming for
broadcast. The provider doesn't create original programming itself; it pays other
companies (HBO, for example, or ESPN) for the right to broadcast their content via
satellite. In this way, the provider is kind of like a broker between you and the actual
programming sources. (Cable television companies work on the same principle.)
• The broadcast center is the central hub of the system. At the broadcast center, the
television provider receives signals from various programming sources and beams a
broadcast signal to satellites in geostationary orbit.
• The satellites receive the signals from the broadcast station and rebroadcast them
to the ground.
• The viewer's dish picks up the signal from the satellite (or multiple satellites in the
same part of the sky) and passes it on to the Set Top Box receiver in the viewer's
house.
• STB receiver processes the signal and passes it on to a standard television.
9. Set Top Box
One of the most important key component of DTH system is SET TOP BOX.
Wiki Definition : A set-top box (STB) or set-top unit (STU) is a device that
connects to a television and an external source of signal, turning the signal into
content which is then displayed on the television screen.
What is STB. Why STB ?
• Digital Set Top Box is a consumer device • User can get more specialized channels
that acts as a receiver or tuner for TV Support for HDTV
signals . • No Ghosting
• It follows DVB/MPEG standards. • Backward compatible with analog TV’s
• They allow users to view premium • Pay as you view
channels • Interactive TV (iTV).
• Provides internet access. • Near Video On Demand
• It is the Key to digital video processing • Internet
• Hard drive storage

12. Talk of Industry experts
• India has around 110 million TV homes, of which, 68 million are cable and satellite
(C&S) homes. With over 3.5 million subscribers, DTH penetration is around five per
cent of the C&S homes.
• A PricewaterhouseCoopers study estimates the figure to reach approx. 10
million by 2010.
• Jawaharlal Goel, Head, Business, Dish TV in THE HINDU. "From the current
market size of around 3.5 million connections, I estimate that by
2015, DTH will reach 30-35 million”
• As per our new research report of Bharat Book
“Indian DTH Market Forecast of 2012”, the number of DTH subscribers is
forecasted to grow at a CAGR of around 29% during 2009-2012.
13. Forecasted Growth DTH
As per our new research report “Indian DTH Market Forecast to 2012”, the number of DTH
subscribers is projected to grow at a CAGR of around 29% during 2010-2012. Presently, the DTH
subscribers constitute only a small proportion of the total TV household in the country, representing
a vast future growth potential.

in all areas whether it is remote or urban , it provides equal benefits to
everyone. Benefits of DTH are listed below:
• Cost effective communication, information and entertainment to all .
• Small size terminals can provide up to 4000 TV channels and 2000 radio
channels through a click of a button and thus brings world’s at least
information, news, entertainment to your home .
• DTH services bypasses mediators and thus content provider comes with
customer directly.
• DTH services are transparent providing digital quality
video, audio, radio, and IP to all at equal prices and other benefits with
reliability.
18. Conclusion
DTH projects in India are just a beginning and we are taking the advantage
of DTH revolution. Direct to home connects urban, rural and remote areas of
the country and provides desire information communication, education and
entertainment at the click of a button.
• Broadband noise will have negligible effect on GMRT Observations, as the
minimum separation distance is 90 meters with the assumption that there is
no DTH system in 100 meter circle from any of the GMRT antennas. Care
must be taken for arm antennas.
• Narrow band noise can cause RFI, in spectral line observations below
400MHz, if located at about 2 km from a GMRT antenna.
