Satellite TV
Satellite TV can be
explained as TV broadcasts received through a satellite that is in
geostationary orbit 22,000 miles above the Earth. An Earth TV station sends
signals to the satellite, which are then relayed back to be received by a dish.
Satellites are capable of delivering both analogue and digital services, but
with the advancement in technology analogue transmissions are giving way to
digital broadcasts.
In its early years satellite TV was quiet demanding in terms of the set-up
costs, voluminous infrastructure and difficult lay-out. In comparison all that
you need today is compact satellite dishes hovering on your rooftop.
Traditionally we have been using broadcast/terrestrial television method
to broadcast signal delivery by radio waves transmitted through open space.
Broadcast stations use a powerful antenna to transmit radio waves to the
surrounding area. Cable TV is very similar to terrestrial television with the
exception that the signal cable goes all the way to the provider where as
terrestrial television goes over the air.
Both broadcast
television and satellite television work wirelessly transmitting programs via
radio signals. But broadcast television can work only within a limited range.
Also radio signals are beamed out from the broadcast antenna in a straight
line. Therefore to receive a perfect reception like you find on cable you have
to be reasonably close to the antenna without too many obstructions.
Satellite television resolves
the issues of range and distortion by transmitting broadcast signals from
satellites
orbiting the Earth. Being high up in the sky, they can cater to a lot more
viewers.
ONCE YOU HAVE your satellite
dishes on you can either programme it yourself but generally satellite TV
customers get their programming from a direct broadcast satellite (DBS)
provider, such as DirecTV or the Dish
Network.
These subscription services
provide different sets of customized channels in the form of attractive
packages giving tough competition to your cable guy. The broadcast is 100%
digital meaning great picture and superb sound.
Dish Network
The Dish Network is a direct broadcast satellite (DBS)
service that broadcasts more then 500 satellite digital television and audio channels
to households in the United States. It was launched in March 1996, and is owned by Echostar.
DirecTV
DirecTV is the Dish Network’s primary competitor in the DBS
service industry in United States. DirecTV is owned by DirecTV Group, a subsidiary of News
Corporation's Fox Entertainment Group.
So when you receive these direct to home (DTH) satellite services there are five
major components involved: the programming source, the broadcast center, the
satellite, the satellite dish and the receiver.
Programming sources
refers to the channels that provide programming for broadcast like the ESPN,
Star Sports, and HBO etc. The direct broadcast satellite (DBS) service provider
simply pays these channels to broadcast their content via satellite.
The broadcast station is where the action takes place. Here, the DBS provider
receives signals from different programming sources and beams a broadcast signal
to satellites in orbit.
The satellites receive the signals from the
broadcast center and rebroadcast them to the ground.
The customer’s dish on the rooftop catches the
signal from the satellite and transmits it on to the receiver in the house.
The receiver receives the signal and exhibits it on a
standard television.
This was our sincere attempt to remove all doubts and
confusions in your mind regarding Satellite TV, Dish network, DirecTV.
It sounded complicated hope we have simplified
it.
