• Doordarshan had a modest beginning with the experimental telecast starting in Delhi in September 1959 with a small transmitter and a makeshift studio.
• On the footprint of the American satellite ATS -6. The first television broadcast was viewed by the people of Rajasthan on 1st August 1975 under the Satellite Instructional Television Experiment targeting the districts of Kota, Sawai Madhopur and Jaipur.
• Special educational programmes were then produced at Delhi.
• On 1st March 1977, Upgrah Doordarshan Kendra (UDK) was set up at Delhi. The programmes produced at UDK for Jaipur were relayed via high power transmitters.
• On 1st June 1987, Jaipur Doordarshan Kendra was set up.
• Initially the Kendra produced only 30 minutes of programming and this was gradually increased. Now its 4 hours of a day.
MODES OF DISTRIBUTION OF TV PROGRAMMES
Terrestrial Satellite Cable
All the above three modes can be either in Analog or in digital domain.
EARTH STATION
Earth Station is a 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.
It is a very important part of satellite communication system for broadcasting of signals.
EARTH STATION CLASSIFICATION
Analog Earth Station
Analog / Digital Simulcast
Digital Earth Station
ASNG
DSNG
C-band or Ku-band
Earth station
DownlinkUplink
Satellite Transmission
Frequency (Uplink) > Frequency (Down link)
6165.5 > 3940.5 MHz
6165.5 = 3940.5 + 2225 MHz
Reasons – (1) To avoid interference between the
uplink and down link. (2) Because the satellite has a limited R.F. power out put.As path loss is proportional to Frequency
PROBLEMS OF ANALOG
One programme per channel / transponder
Comparatively noisy Ghosts in Terrestrial Transmission Lower quality with respect to VCD,
DVD digital media Fixed reception
WHY DIGITAL ?
More programmes per channel / Transponder i.e. spectrum efficient
Noise-Free Reception Ghost elimination CD quality sound & better than DVD
quality picture Reduced transmission power
Flexibility in service planning
-quality / Bandwidth
trade offContd...
WHY DIGITAL ?
New services like Pay TV, VOD, Teletext, Data, Surround sound, Multimedia etc.
Interactive services like e-commerce, e-banking, tele-quiz, tele-games etc.
Automated operation in broadcast plan Non availability of analog systems in
near future Future of TV transmission – DTH, DTT &
Digital Cable
SATELLITE COMMUNICATION
Started in 1957 in Russia (Sputnik) Started in India on 14.04.82 (INSAT 1A)
SATELLITE BROADCASTING-DIGITAL
Tremendous savings in satellite capacity.
10 to 14 TV channels per 36 MHz Transponder
( DVB-S , MPEG 2 )
25 to 50 TV channels in 36 MHz Transponder
( DVB-S2, MPEG 4 / WM 9)
Excellent quality of signal reception.
New services like VOD,PPV etc.
ADVANTAGES OF SATELLITE
Large coverage area (42% of Earth)
Very High B.W. (Wide band Multi channel)
Terrestrial uncovered pockets like valleys and mountains regions.
Uniform Signal.
Establish easily for Point to Point Communication.
NONLINEAR EDITING SYSTEM
Modern editing method which involves being able to access any frame in
a video clip with the same ease as any other.
Its audio/video equivalent of word processing, called as desktop editing in
the consumer space.
Some editing software can now be accessed free as web applications; eg.
Cinelerra(focused on the professional market) , Blender 3D.
Some, like Microsoft’s Windows Movie Maker or Apple’s iMovie, come
included with the appropriate operating system.
MEDIA 100 - FINAL CUT XML INTERCHANGE
With this one can export a Media 100 program timeline to an XML document and then import that document into a Final Cut Pro sequence for further editing.
Certain features are discussed further with pictures in the coming slides.

Here's that program after it's been exported to XML and imported in Final Cut Pro:
CONCLUSION
These non-linear video editing systems typically use compression techniques developed by the Joint Photographic Experts Group (JPEG) or the Motion Picture Experts Group (MPEG).
Thus, conventional non-linear editing system tools are complex and require a high degree of manual interaction and configuration to produce a final edited result.
World's most popular broadcast news production system.
Used by journalists in almost 700 newsrooms in some 60 countries across five continents.
ENPS is the ideal solution, featuring scalable, dependable architecture that can be tightly integrated with third party products.
