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.
How Does Satellite Television Work?
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.
One other hassle with TVRO is that the big dish has to be moveable to keep track of more satellite, because C-Band satellites carry less channels than KU-band satellites. This dish movement, however makes it possible to receive free channels and feeds or even unedited C-Band news material being sent to headquarters by field correspondence or a news crew, they are usually not scrambled.
What Is Direct Broadcast Satellite Or DBS And What Makes It Better Than TVRO?
Once you begin to move beyond basic background information, you begin to realize that there's more to the future of satellite TV vis a vis Internet television software than you may have first thought.
DBS is satellite TV broadcast thorough Ku-Band satellites that work on higher frequencies with stronger signals than C-Band or TVRO, which makes it possible for you to install smaller dishes for receiving their signals.
People who live high up on apartment buildings favor the DBS since installing an 18 inches dish up there is possible. Another advantage of the DBS over TVRO is that the dish is stationary needing no maintenance plus, the installation is free in most cases.
This is made possible because DBS television satellites are usually in geosynchronous orbit that is stationary in the sky relative to the Earth, because each satellite is launched into space at around 7,000 mph to settle at around 22,200 miles above the Earth.
With this speed and height, the satellite revolves around the earth once every 24 hours in juxtaposition with Earth's own rotation. This is what makes it possible for your 18 inches dish to remain in a fixed position with the satellite without requiring adjustment.
What is Internet Television and Is It Better than Direct Broadcast Satellite?
Internet television as the name implies refers to Television programs streamed onto a PC or Laptop through the Internet. There are different types of Internet television services. Some of them are recorded rebroadcasts while others are live broadcasts made possible with ingenious software. You can connect to thousands of satellite television services simultaneously. A wide range of viewing choices - unlimited TV shows, Movies, Sports, Soaps and more.
You don't need any hardware such as decoder, wire, dish or antenna making. You can watch your favorite programs, even outdoors, from all over the world, so long as you have internet connection. Internet television is just a hassle free way of watching a lot more numbers of satellite TV programs and channels free of monthly satellite television subscription fees.
What Is The Future Of Satellite TV Vis A Vis Internet Television?
What would be the future of Satellite Television depends on several factors: For instance, even before the advent of Internet television satellite television companies did not depend on subscription fees for their survival.
Advertising pays a big chunk of the bill for you to watch satellite television even at the present rate you might consider very exorbitant
License fees are another way through which satellite television services are sustained. For instance, If you are in the UK and you have equipment that is capable of receiving TV signals then the law states you must pay for a TV license.
Today, there already exist broadcasters who use only advertising to pay for their service and so allow viewers free viewing of their programs, so in my opinion watching satellite television programs free on your PC or Laptop will not kill satellite television, rather Internet television will increase the number of viewers for satellite television services and lead to more and better priced advertising charges.
Of course, it's impossible to put everything about the future of satellite TV vis a vis Internet television software into just one article. But you can't deny that you've just added to your understanding about the future of satellite TV vis a vis Internet television software, and that's time well spent.
