Satellite TV is simply TV that is transmitted through the use of communication satellites. It was first introduced in the market in the 1990s. Back then, a satellite TV was made of a large metal disk that people often set up in their yards. It was bulky and quite expensive. There was also no controlled programming yet, which enabled satellite TVs to pick up "wild" feeds, some of which were not intended for public viewing.
Today, satellite TV has evolved in a lot of ways. It is much smaller and can be placed on rooftops. The programs are selected by a direct broadcast satellite (DBS) provider, which offers these programs as a package to their subscribers. DBS systems, also known as "direct-to-home," are often called "mini-dish" systems. The DBS system ensures that only paying subscribers gain access to the TV content.
How does a satellite TV work?
A DBS satellite system is composed of five components. These are the programming source, the broadcast center, the satellite, the satellite dish, and the receiver. The programming source refers to the channel that provides the programming. There are different programming sources, such as STAR movies, ESPN, HBO, and Disney channels. The DBS provider pays these programming sources for the right to broadcast their programs via satellite.
The broadcast center is where the satellite TV provider receives the signals coming from the different programming sources. The broadcast center transmits broadcast signals to satellites, which receive these signals and send them back to earth. These signals are then received by a satellite dish which, brings them to the receiver connected to a standard TV.
