In the past when you first got to know
cable TV channels, you should be fascinated by the picture, which was clean
enough and the choices of channels were overwhelming. Not long ago, you just
found out that now there is also such a thing as satellite TV, the picture is
said to be sleeker and the channel choices are even more numerous. You became
curious, what satellite TV is. There is one more thing that I'm also curious about, what is satellite
internet?
Conceptually, satellite TV is a wireless
system for delivering television programs directly to the home of the viewer,
while broadcast TV and TV transmitters broadcast their programs via radio
signals. Before entering into a satellite TV system, let's look at the
beginning of everything, which is a broadcast station that uses an antenna to
emit radio waves to the surrounding area. The user can later capture the signal
with a smaller antenna - like the antenna we still see a lot above the house.
The main limitation of TV transmitters is the range. The radio signal is used
to broadcast television broadcasts via a transmitting antenna in a straight
line. To capture this signal, you must be in a straight line with the antenna.
Small obstacles such as trees or small buildings do not matter; big obstacles,
like the earth, will reflect these radio waves.
If the earth is very flat, surely you can
catch the beam even though it is thousands of kilometers from the source. But
because planet Earth is naturally curved in shape, the range of the signal line
can be interrupted. The broadcast TV's signal is also often disturbed, even in
close areas. To get a clear signal like cable TV, you need to be close enough
to the transmitter antenna without too many obstructions. Well, satellite TV solves the problem of distance and interference
by emitting emission signals from satellites that surround the Earth's orbit.
Because satellites are high in the sky, more customers can be reached. The
satellite TV system emits and receives radio signals using a special antenna
called a satellite dish. The audience of satellite TV at the beginning of its
appearance, including adventurers. They can use satellite dishes to find
special broadcasts that are not actually for the general public, using
satellite dishes and receivers. They can even capture broadcasts abroad, NASA
activities, and various other things transmitted via satellite.
Some satellite owners are still looking
for such broadcasts themselves, but most satellite TV customers now get their
broadcasts through the Direct Broadcast Satellite (DBS) provider. the provider
chooses the program and broadcasts it to the customer as part of the package.
The goal of the service provider is to give your TV dozens, even hundreds of
channels in a form similar to its rival, cable TV. Unlike previous broadcasts,
broadcasting by the provider is entirely done digitally, which means better
picture and sound quality. If you wanted to know more about satellite TV, all you have to do is just keep digging
