Satellite Television - A Technological Wonder


									Satellite television is a broadcasting platform where the TV programs are
broadcasted by communication satellites. The TV signals from the
satellites are received by a circular shaped antenna, which is also
referred as dish TV antenna. The signals from the dish antenna are then
transferred to the set top box or satellite receiver. From this device
the signals are transmitted to the TV set. So here you can see that a
typical satellite television kit contains two important components. One
is the satellite receiver and the other one is the satellite receiver.
Dish antennas play a major role in this TV broadcasting platform.
Previously these things were made from costly metal units. They also used
to be big in size and weighing almost a ton. Because of their large size,
they used to take up huge space in a premise. The installation of early
dish antennas was full of hassles. Today the satellite dish antennas have
become smaller in size and you can install them on the rooftop or in the
balcony of your residence. The antennas are now made with high quality
plastics instead of heavy and expensive metals. This helped the antennas
to become lightweight and affordable.

  The signals that are delivered from the communication satellites have a
long path to follow before reaching to your television set. The TV
signals, which are transmitted from the satellites, are high quality
digital data. The data is then compressed by using a video file
compression technology. The technology that is used for compressing the
incoming satellite TV signals is MPEG. Compressing the incoming video
data allows the broadcaster to deliver greater number of TV channels to
its subscribers.       Some of the service providers of dish TV in the
United States are now broadcasting their TV programming contents in MPEG
4. This advanced compression technology is used for streaming video
contents to the small screen devices such as personal computers, mobiles
and PDA devices. This technology is highly efficient and is capable of
generating brilliant images.      In dish TV systems, there are five
major components. They are the programming source, broadcast center,
satellite, dish antenna and the satellite receiver. Programming source is
actually referred to the channels that contain TV programs for broadcast.
The TV contents are developed by some of the leading channel companies
like HBO, ESPN, CNN, etc. Direct to Home or DTH service providers pay
certain amount of fees to the channel companies to earn the right to
broadcast the content via satellite.       The next major component of
DTH TV is broadcast center. It is the main control center of direct to
home television platform. The signals from various programming source
makes it entry to this place in the first stage. After that the signals
are then released to geosynchronous satellites in space. The next
component is the geosynchronous satellites whose jobs are to receiver the
signals from the broadcast station and resend it to Earth.       The last
two components are the satellite receiver and the dish antenna. The job
of a dish antenna is to get the signals from the satellites and the job
of a receiver is to process the signals and transmit that to a TV set.
This is how satellite TV works.       For more information about
satellite TV channels and services, please get in touch with your
respective Dish Network Programming provider. Related Articles - dish
