Doordarshan's Signature Tune and
• It all started 52 years ago, on 15 September 1959. With a humble
beginning and a little support from All India Radio. Doordarshan (DD)
started its transmission and gave birth to Indian Television. When we
think about Doordarshan the first thing that comes in our mind is the
sad signature tune which would play before the transmission every
Morning, Afternoon & Evening Sessions. Similer to the AIR Signature
tune , the Doordarshan's Signature Tune is embedded in our minds till
it got a setback due to the upsurge of Cable television in the early 90's.
This Nostalgic piece of music was composed by Ustad Ali Ahmed
Hussain Khan with Pandit Ravi Shankar in 1974. In 1976 the DD
Montage was designed at National Institute of Design (NID). In the next
two decades from the early 80's to mid 90's, Doordarshan produced
some of the finest serials on Indian Television. The people born in that
generation when there was no other channel than DD will & definitely
do miss it. This slow mournful Signature Tune has become a cherished
memory for generations of Indians all across the world.

COMPONENTS OF TV STUDIO
• Vision mixer and Audio consoles
• Post production and video effects
• Supporting services like AC, UPS
• 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.
• It has many input sources such as cameras,
VCR/ server, Graphics/Character
• Out of these input, any source can be taken
• Sources can be changed as cut to cut,
dissolve, wipe and other special effects.

OB Van & DSNG
• 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
• 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.
• DSNG is a portable uplinking centre.
• 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
• The signal is up-linked from the Earth Station and
received by many down link centers in TV broad casting
• Two Types: 1) Analog, 2) Digital
• Digital Earth Stations are widely used because of various
advantages over analog.
Major Components of Digital Earth
• PDA (Parabolic Dish Antenna)
• Wave Guide / Low Loss Cable
• HPA (TWTA, Klystrons)
• Up converter
• IRD (Integrated Receiver Decoder)
Aid of antenna
Produces radio wave
Connect earth station
Types of TV Transmitters
VLPT’s, LPT’s & HPT’s
• A 10 KW HPT is only 10-20%
• It has beamwidth of 360
deg, hence can cover upto 65
kms of area around it.
• It has various other supporting
units with it to maintain the
quality of s/g to be Txd. Like-
Monitoring section, blower
section, amplification section
ANTENNA & SATELLITE
• An antenna (or aerial) is a transducer
designed to transmit or receive
electromagnetic waves. In other words,
antennas convert electromagnetic
waves into electrical currents and vice
• Isotropic antenna (idealized)
o Radiates power equally in all directions.
• Dipole antennas-
o Half-wave dipole antenna (or Hertz
o Quarter-wave vertical antenna (or
