A Short Heads Up Into How Satellite Television Works
| by Michael Stevens | April 30, 2008
Did you ever wonder what are the things that make satellite tv function and which are its most important functions? This explanatory article will undoubtedly answer some of your fundamental questions on this subject.
Firstly, let us establish some of the fundamentals: satellite tv at its root is the transmission of audio and video signals, sent by the satellites to the dishes which are on the ground level. These satellites are found on a geostationary orbit.
Indeed, satellites can almost be regarded as a contemporary wonder and they are the things which make so many things possible, and not only in satellite tv. They have deeply revolutionized communications. They orbit the planet in a place called Clarke Belt, which is a region in space found 22,300 miles above the Equator line.
And now letâs talk something about the transponders. They are objects that broadcast the signal to the Earth, and every satellite has a a different number of transponders. The signals that are broadcast are different in nature. Usually, they are transmitted on a few important bands, the Ku Band, the C Band and the Ka Band. The frequency of the signal is the most important element which is being defined by these different types of bands.
Now, these signals must travel over 20,000 miles, 22,300 more precisely. They are then picked up on the ground's surface by the satellite dishes. A satellite dishâs main purpose is to pick up these signals and carry them further away. Even though a dish can be as small as 18 inches in diameter, it will still successfully deliver the signal to the feedhorn.
And now, in this journey, the satellite signal gets to the feedhorn. So what is a feedhorn? A feedhorn is an important part of the satellite dish. The feedhornâs job is to receive the signal and carry it over once more to the LNB. Then, the LNB will amplify the signal in order to transform it to a frequency which will be more appropriate for a transmission that is done over cable.
And now we talk about another enigmatic term, the LNB. LNB is an acronym of Low Noise Block, and its goal is the one mentioned in the previous paragraph. The cable is known under the term of IFL, an acronym of Intra Facility Link. The IFL is the means with the help of which the LNB carries the signal to your personal receiver. Then, the last step of the process is done by the receiver, which carries the signal to your personal television set.
And here is where the signalâs journey ends. It is very interesting when you think about all the technology which is involved in the process and all the complicated steps and transformations the signal will have to undergo. So now you finally know how satellite television works at its basics.
