This document provides an overview of broadcasting via terrestrial transmission and satellite transmission. Terrestrial transmission uses frequencies between 40-70 MHz and can transmit signals up to 100 km. Satellite transmission involves geostationary satellites orbiting 35,786 km above Earth that receive and transmit signals, allowing coverage of large areas ignoring political boundaries. Key benefits of satellite communication include remote sensing for conditions like weather as well as communication with aircraft and remote areas.

1. BROADCASTING
MADE BY :-
SOURABH
KANT

2. BROADCASTING
• ANALOG CABLE T.V. TRANSMISSION

3. TELEVISION TRANSMISSION
• TERRESTRIAL TRANSMISSION.
• SATELLITE TRANSMISSION.

4. TERRESTRIAL TRANSMISSION
 TERRESTRIAL TRANSMISSION is the transmission being made parallel
to the ground
 It’s frequency range is 40-70 MHz
 One transmitting station could transmit the signal for only 100 Km
diameter of clients
(Tx station)

5. SATELLITE TRANSMISSION
 Satellite transmission involves an intermediate machine what we called
as satellite.
 It’s sole duty is receiving and transmitting.
 The most popular orbit is the Geostationary orbit for the communication
satellite .
 Which is present at 35786 Km from the earth surface.
 Only three satellites are used to cover the earth.

7. IMPORTANT FEATURES
 Very large area of earth is visible from satellite (about 42%)
 Satellite offers communication with remote communities in sparsely
populated area
 Satellite communication ignores political boundaries as well as
geographical boundaries
 Satellite provides communications with moving aircraft from ground
control stations across the country
 Satellite provides remote sensing i.e. Weather condition , oil field, water
pollution etc.

9. SATELLITE

10. UPLINK
 UPLINK is the process of sending the signal from the main station to
the satellite
5.9 TO 6.2 GHz
TO SATELLITE

11. LNB DETAILS
 LNB is connected at the receiving satellite dish.
 LNB is used just to convert incoming RF input to IF (intermediate
frequency)
