How Satellite TV Works

How Satellite TV Works 1Satellite TV has come a long way since the early 1990’s. Remember how big the first cell phones were? In a similar way, the first satellite dishes were big, bulky, and not very attractive and were mainly used by people living in rural areas, unable to get TV in any other way. However, just as cell phones have gotten smaller over the years as technology has advanced, so have satellite dishes.

Satellites that beam content down to those satellite dishes work because they are in what is called geosynchronous orbit, an orbit with an orbital period that matches the Earth’s rotation, so that they are always in the same part of the sky. These satellites send signals to your satellite dish faces their position in the southern sky. As long as your dish remains aligned properly, your signal will be clear and consistent. It’s a common misconception that satellite signals are lost with the a little bit of wind, rain or snow. In fact, satellite TV signals have proven to be more reliable than cable! Statistics shows that cable TV outages average 3-5% a year while satellite TV outages average a mere 1% annually.

Satellites are a highly efficient way of broadcasting signals because they can carry so much content to such a large area of the country without needing the cable connections that cable companies do. Satellite programming is all digital, giving you better picture and sound quality. Here’s a look at some basic components of satellite TV:

  1. Programming source: The channels that provide programming to broadcast. DISH pays networks like ESPN and HBO for the right to broadcast their content to DISH subscribers.
  2. Broadcast center: This is the hub of the satellite TV system where DISH receives signals from the satellites of programming sources like ESPN and HBOand re-sends the broadcast signal back up to the DISH satellites in geosynchronous orbit.
  3. Satellites: Receive the signals and rebroadcast them back down to Earth to meet your satellite dish.
  4. Dish: The satellite DISH on your roof or in your yard picks up the signal from the satellites in the sky and passes the signal to the receiver located in your home.
  5. Receiver: Your Hopper or whatever receiver you have then processes the signal and passes it to the TV; you then get television programming!

 

The device at the end of your satellite dish’s arm is called a “low noise block” or LNB. The signal from DISH’s satellite bounces off the dish and into the LNB; the LNB filters out any background noise and amplifies the signal so it can be divided into channels.

DISH receivers interpret the signal from the LNB into a format that can be viewed by your TV, allowing you to switch between individual channels at the same time. DISH receivers also allow you to record and store programs for later viewing (DVR hard drives) and to use parental controls to block certain shows you don’t want your children to watch. DISH offers customers standard, high-def or DVR receivers and all three have various features and functions.
