Introduction to Satellite TV

So you have seen dishes and receivers outside your home and yes you know that they are the main equipments of satellite tv. But do you know how satellite tv works? Do you know how it makes your favorite programs viewable by you in your tv?

Don't you know that the Moon is considered a satellite? And the Earth would be a satellite to the Sun. To get to know satellite, it is actually any object that orbits a larger object. Following that assumption made man to make man-made satellites. Man-made satellite is placed into position just over 20,000 miles above the Earth. It is then programmed to orbit the Earth so that the satellite stays in synchronization with the Earth, specifically it's rotation. So if you are living in United States, when a satellite that is positioned will stay over the United States, despite the Earth?s constant movement. Many satellites use rechargeable batteries as their power source, feeding off the Sun?s natural energy source via large solar panels.

So with regards to satellite tv, first of all, you will need to understand how the antenna broadcasting system works. The first known tv broadcasting antennas use radio waves to transmit their programming. Then, each broadcasting station operates at a unique frequency that identifies the station to the FCC and allows your receiver to select a particular channel. After that, the radio waves are carried from the station?s antenna to yours. And when tuned to the specific frequency, it will pick up the waves for your tv to interpret and project. However there are radio waves which can only travel so far when emitted from an antenna and they are then subject to distortion as objects get in between the two points of communication.

It was only a matter of time before the media industry began pondering the satellite?s potential in television. Just like traditional broadcasting antennas, satellite television works with radio waves as well but with a much broader range.

If the the larger dishes transmitted analog signals, then the smaller dishes send digital signals. Compare to older dishes which rarely required decoding, smaller dishes produce a higher quality of sound and video. Digital signal is encoded into MPEG-2 format, just like the format used in DVD?s. It will then transmitted to your receiver box where it is decoded and translated into an analog signal that is then fed to your television. Digital produces enhanced video and audio that you just can?t get from analog.

It never stops there yet. So, in order to receive satellite programming, you will need broadcast satellite providers. What are these providers? These providers have contracted with the various programming providers such as HBO, Cinemax and of course, all your local channels. Your satellite tv providers could be Dish Network or DIRECTV, it's up to you what to choose. Programming providers will then send their programs to the satellite providers who will send back out via satellite to your dish. And then transmitted from the dish to your receiver box where it is decrypted and shown on your television.

That's it! Now you can view your favorite shows in your tv. It is not surprising why many people ar now using satellite tv. With the ability to supply you with endless programs and best of quality pictures, you can never ask for more. Satellite TV has a lot to offer its customers. You will be able to reap all the rewards and offers that are available through.
