The following article includes pertinent information that may cause you to reconsider what you thought you understood about the relationship between satellite television and Internet television. However, the most important thing is to read with an open mind and be willing to revise your understanding if necessary.
What Is Satellite Television?
Satellite television refers to television service beamed to subscribers via orbiting communications satellites high above earth from a distance of between – 22, 000 to 37, 000 miles making it possible for television programs to reach wider areas than was possible with either the traditional terrestrial or cable television which out reach was hampered by earth’s curvature and distance.
When Was The First Satellite Television Aired?
It was in 1962 that the very first television signal was up linked from Europe on to the Telstra satellite and beamed over North America. Anik1 was the first domestic North American satellite launched in 1973 in Canada.

Well, without going technical, it will interest you to note that the television signals you receive from communications satellites are really first sent up from ground stations via very big (9 – 12 meters) dishes to an orbiting satellite that in turn beams the signals down to earth and on to your receiver’s parabolic dish’s focal point and a LNB or low noise blocker component converts ands send the signals to your decoder box where the final conversion is done to the signals so that it becomes the sound and pictures you watch.
There are also different brands of mobile none parabolic dish receivers for use in vehicles and other mobile platforms. In this case satellite television signals are received with a satellite antenna and directed through a satellite decoder box and an oscillator converts it to L-band range of frequencies that an on-board electronics finally converts to the standard frequency usable by normal television sets.
What Is A TVRO?
Television Receive Only or TVRO is the forerunner of satellite television viewing at home. The very big dish size, about 3 – 6 feet, required to run C-Band frequencies of about four G Hertz meant that not most people could own it due to the very exorbitant cost of installing one, and the space for installation.
