How Satellite TV Works

You've got a Satellite Dish, a Dish Network Receiver box and magically, the result is great Dish Network Programming on your television set.  Want to know how the two work together?
 

The Science Behind Satellite TV

All magic aside, there's actually quite a bit of science behind all that great Dish Network Programming, science that has drastically changed the way we look at home entertainment.  After all, before Satellite TV and cable there was only traditional television broadcasting antennas.  These antennas use radio waves to transmit programming from source to Dish Network Receiver, producing the Local Channels you receive on your television set. This works fine if you're close to the source but throw a little distance or a few obstructions between the two and the signal quickly becomes distorted.

But then came the satellite.

 

Satellite TV - From 22,500 Miles High

Using the same premise as your traditional antenna, Satellite TV broadcasting produces a much stronger signal.  It also has the advantage of being over 22,000 miles in the sky and is programmed to orbit the Earth.  This allows the satellite to stay where it should, providing a clear and unobstructed signal to the source. 

Inside the satellite is an electronic box containing a power source, typically rechargeable batteries with solar panels that can feed off the Sun's natural energy.  Also inside are communication and navigational systems to keep the satellite in proper orbit and relay information back and forth via the same radio waves used by antenna broadcasting systems.  These satellites send a signal to your personal Satellite Dish which then routes it to your Dish Network Satellite Receiver for processing.   

 

To get that multi-channel premium Dish Network Programming you love so much, your satellite provider Dish Network) contracts with all the various programming companies like Showtime®, HBO®, Cinemax, Starz® and yes, your Local Channels Networks too.  They put together Dish Network Programming packages for you to purchase, depending upon your personal needs and preferences.   The programming providers send their signals to the satellite tv providers where it is compressed and converted to MPEG-2, the same format of your DVD's.  This converted signal is sent back up to the satellite so it can be sent out to the subscribers.  When the digital signal reaches your Dish Network Receiver, the smart card inside determines which portions of the Dish Network Programming you should have access to.  Those portions are then decrypted and converted back to analog so that they can be read by your television.The result is a crisp, clear picture and sound unlike anything you'd get with the traditional antenna.
