IntroductionProcess of sending information to a distant place is called Broadcasting

bull Means of Broadcasting in India 1 Terrestrial 2 Satellite 3 Internet

bull Both AIR amp DD make use of both Terrestrial amp satellite 5

Introduction contdhellipbull Broadcasting started in India in the year

1923bull AIR was formed in the year 1936bull In 1947 AIR was covering 25 amp about

11 of land amp population respectivelybull 1st TV Station was established in Delhi in

1959bull TV was separated from AIR in 1976bull DD has 1500 Transmitters and 70

Production centers across the Country6

TV studio

7

bull A television studio is an installation in which television or video productions take place

Components of TV studio

bull Camerabull Lightingbull Microphonesbull Vision mixer and Audio consolesbull MSRbull VTRbull Acousticsbull Post production and video effectsbull Supporting services like AC UPS

8

Vision Mixer

9

bull 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

bull It has many input sources such as cameras VCR server GraphicsCharacter Generatorsetc

bull Out of these ip any source can be taken as op

bull Sources can be changed as cut to cut dissolve wipe and other special effects

MSR (Master switching Room)bull It is the heart of the

studiobull Most of the switching

electronics is kept eg camera base stations switcher main frame SPG Satellite receivers MW link DDA amp most of the patch panels

bull Signal is routed through MSR

bull Signal can be Monitored at various stages

12

Earth station

13

bull Earth Station is a very important part of satellite communication system for broadcasting of signals

bull It is an uplink center from which the signals are fed to Satellite for distribution in a specified area covered by the Satellite

bull The signal is up-linked from the Earth Station and received by many down link centers in TV broad casting via PDA

bull Two Types 1) Analog 2) Digital

bull Digital Earth Stations are widely used because of various advantages over analog

OB Vanbull A typical OB Van is usually divided into 4 partsbull The first and largest part is the production area or

sitting area for all directors amp producersbull The second part of a van is for the audio engineerbull The 3rd part of the van is video tapebull 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

17

If there is a live program to be telecast following options can be choosed

Microwave link DSNG (digital satellite news gathering)

Microwave link

18

Audio and video signals are feed to micowave transmitter Input video is processed and up converted to 1225 amp 1230 GHz Approx transmission power is 600 milli watts Transmit receive station is 11 m in diameter

DSNGbull Audio video input is processed by

an encoder as per mpeg-2 standardbull The audio and video along with

other data are multipliedbull Multiplied data forward error

corrected using a standard technique

bull Error corrected codes are QPSK modulated at 70 MHz

bull The modulated signal is up converted to power amplifiers

Doordarshan is loosing the RaceNot running with recent trends and Viewers Expectations No use of latest virtualization visualization techniques in

educationalinformative programs so due to this they are so Boring

Very Less TRP then Other Competitors in market like colors zee star etc

Youth Content in Programs are so less ie Music Employment Programs Personality Improvement programs Quiz programs etc

Not Utilizing their full assets Not interested in market survey at all(No feedback from

users side) 21
