How Satellite Television Works
When satellite television (or sat TV) first made its debut in the early 90s, satellite dishes were large and expensive metal items that took up space. Today, satellite dishes are compact and easily fit on rooftops. One of the greatest things about sat TV is how it is opening up television choice to everyone around the world. It is popular and most of all - it is affordable. Satellite TV companies are enticing more viewers every day with new movies, sports and world news and the pledge to produce a movie-quality picture and sound. Satelite TV presents many solutions to the growing problems that cable TV has been facing. Even though satellite TV technology is constantly developing, many people have already chosen it as their preferred television choice. Whatever your needs, Satellite TV has a solution for you.
In this article, we’ll find out how sat TV works, from TV station to TV set. We’ll also learn about the changing landscape of TV viewing and some basic differences that distinguish satelite TV from cable and over-the-air broadcast TV.
What Are Satellite Television Systems?
Satellite Television never ceases to impress: the channels are infinite and the independence is an added bonus. Conceptually, satelite TV has many similar components to broadcast TV; it’s a wireless system that delivers television programming directly to your home. Both broadcast television and satellite television systems transmit programming via radio signals. Broadcast stations use a powerful antenna to transmit radio waves to the surrounding area. The main limitation of broadcast TV is range. Radio signals used to broadcast television are discharged from the broadcast antenna in a straight line. In order to receive these signals, you have to be in the direct line of sight of the antenna. This is a bit of problem since the Earth is round making it impossible for you to have a straight line, causing broadcast signals to be distorted. In order to get a perfect picture through cable you need to be in a pretty close proximity to the antenna. With sat TV, the process becomes much simpler.
Problem Solving with Satellite Antenna
Satellite Television offers a solution to range problems by transmitting broadcast signals from satellites antennas circumnavigating the Earth. Since satellites are high in the sky, there are a lot more patrons in its line of sight. Satellite TV systems transmit and receive radio signals using specialized satellite antennas called satellite dishes.
Satellite TV is a huge improvement over all types of Cable TV including digital. Much has been written about the difference between Satellite TV and Cable. Digital signals picked up through the "Ku" band are an MPEG-2 compressed video signal, which allows far more channels to be squeezed through without damaging clarity. At the core, this is all there is to satellite dishes. Satellite dishes are also very easy to self-install and if you’re considering installing this dish on your own you should read how to install your satellite dish.
Simply Sat TV
Most satellite consumers get their programming directly from a satellite TV Company, such as DIRECTV® or DISH Network®. The satellite TV Company creates program packages and broadcasts them to subscribers. Basically, the provider’s goal is to bring hundreds of channels to your TV.
Simply put satellite Television is just another way of delivering multi-channel television and an incredible way to enjoy your viewing experience.
