Broadcasting:
Process of sending information to a
distant place is called Broadcasting.
Means of Broadcasting in India:
1.Terrestrial
2.Satellite
3.Internet
Both AIR & DD make use of both
Terrestrial & satellite.

8. A SHORT HISTORY
8
1- Broadcasting started in India in the year
1923.
2- AIR was formed in the year 1936.
3- In 1947, AIR was covering 2.5% & about
11% of land & population respectively.
4- 1st T.V Station was established in Delhi in
1959
5- T.V was separated from AIR in 1976
6- DD has 1500 Transmitters and 70 Production
centers across the Country.

9. TV STUDIO
9
A television studio is an installation in
which television or video productions take
place by using several supporting
equipments.

10. COMPONENTS OF TV STUDIO
10
Camera
Lighting
Microphones
Vision mixer and Audio consoles
MSR
VTR
Acoustics
Post production and video effects
Supporting services like AC, UPS

11. VISION MIXER
11
1. A vision mixer (also called video switcher, video
mixer or production
switcher) is a device used to select between several
different video sources and in some cases mix video
sources together and add special effects.
2. It has many input sources such as cameras,
VCR/ server, Graphics/Character
Generators,etc.
3. Out of these i/p, any source can be taken
as o/p.
4. Sources can be changed as cut to cut,
dissolve, wipe and other special effects.

12. TYPICAL VIDEO CHAIN
12
1-Use PAL system (720*576) in 4:3 aspect ratio.
2-For TV Transmission It uses VSM .
3-It Uses C Band( DTH uses Ku band) and in the transmitter room it
has two 10 KW Transmitters for Broadcasting.

13. TYPICAL AUDIO CHAIN

14. MSR (MASTER SWITCHING ROOM)
14
It is the heart of the
studio.
Most of the switching
electronics is kept e.g.
camera base stations,
switcher main frame,
Satellite receivers, MW
link, DDA & most of the
patch panels.
Signal is routed through
MSR.
Signal can be Monitored
at various stages

15. EARTH STATION
15
Earth Station is a very important part of
satellite communication system for
broadcasting of signals.
It is an uplink center from which the
signals are fed to Satellite for distribution
in a specified area covered by the
Satellite.
The signal is up-linked from the Earth
Station and received by many down link
centers in TV broad casting via PDA.
Two Types:
1) Analog
2) Digital
Digital Earth Stations are widely used
because of various advantages over
analog.

16. MAJOR COMPONENTS OF DIGITAL
EARTH STATION
16
• PDA (Parabolic Dish Antenna)
• FEED
• Wave Guide / Low Loss Cable
• Up converter
• Modulator
• Encoder
• Multiplexer
• IRD (Integrated Receiver
Decoder)

17. OB VAN
17
Outside broadcasting (OB) is the electronic field
production (EFP) of television or radio programmes
(typically to cover television news and sports television
events) from a mobile remote broadcast television
studio.

18. BLOCK DIAGRAM OF OB VAN

19. OB VAN
19
A typical OB Van is usually divided into 4 parts.
The first and largest part is the production area or sitting
area for all directors & producers.
The second part of a van is for the audio engineer.
The 3rd part of the van is video tape
The 4th part is transmission where the signal is
monitored by and engineered for quality control purposes
and is transmitted or sent to other trucks.
If there is a live program to be telecast following options
can be choosed.
 Microwave link
 DSNG (digital satellite news gathering)

20. MICROWAVE LINK
20
 Audio and video signals are feed to micowave transmitter.
 Input video is processed and up converted to 12.25 & 12.30 GHz.
 Approx transmission power is 600 milli watts
 Transmit/ receive station is 1.1 m in diameter.

21. DSNG
21
• Audio/ video input is
processed by an encoder as
per mpeg-2 standard.
• The audio and video along
with other data are multiplied.
• Multiplied data forward error
corrected using a standard
technique.
• Error corrected codes are
QPSK modulated at 70 MHz.
• The modulated signal is up
converted to power
amplifiers.

Doordarshan is in the RACE !
1- Free To Air Service provider.
2- India’s National TV Channel / wireless Broadcasting
Media
( DD National/ DD News / DD Metro Etc. )
3- Directly works Under Government Policies .
4- Terrestrial Broadcasting of Programs In the regional
Languages
that have similar contents that belongs to the specific
region.
Likewise DD Bareilly, DD Lucknow , etc.

23. 23
Doordarshan is Loosing the RACE !
1- Not running with recent trends and Viewers
Expectations.
2- No use of latest virtualization /visualization technics in
educational/
informative programs so due to this they are so Boring.
3- Very Less TRP then Other Competitors in market, like
colors, zee,
star etc.
4- Youth Content in Programs are so less. i.e. Music/
Employment

24. 24
Suggested Solutions
1- Give Chance to Young minds, so they
can show their Creativity.
2- Best Optimized use of Presently
availiable resources.
3- Understand the Funda’s of Todays
Market. 4-4-4- Proper Promotion of
programs by paid and free
mediums.
Paid-High Resolution Cam/ Proper
editing
software.
Free- Facebook / Google/ Youtube.
5- Take support from the Experienced
Co-operate persons to rise fast.

Conclusion
1-Overall a very nice experience .
2-Learn about Team work power.
3-Updated my knowledge about the National
Income and
also Doordarshan role in it.
4- Practically watched how studio recording
