In the early 1990’s satellite television first hit the market and home dishes were huge and expensive metal units. Only the most die-hard TV fans during the early years would go through all the hassle and expense of putting in their own dish. It was a lot harder to get than broadcast and cable TV.
You can see compact satellite dishes nowadays on rooftops all over the United States. When you drive through several rural areas that are beyond the reach of the cable companies you will find dishes on just about every house. Everyday the major satellite TV companies are luring in more consumers with movies, sporting events and news from around the world and the promise of movie-quality picture and sound.
Satellite TV technology is still evolving, it has already become a popular choice for many TV viewers. It offers many solutions to broadcast and cable TV problems.
Early satellite TV viewers used their expensive dishes to discover unique programming that wasn’t necessarily intended for mass audiences. They were able to pick up foreign stations, live feeds between different broadcast stations, NASA activities and a lot of other stuff transmitted using the satellite dish and receiving equipment.
Today most satellite TV consumers get their programming through a direct broadcast satellite (DBS) provider. But some satellite owners still seek live feeds from broadcast stations and other sorts of programming on their own. The provider selects programs and broadcasts them to subscribers as a set package. Their goal is to bring hundreds of channels to your TV in a form that comes close to the competition, cable TV.
Early satellite television was broadcast in C-band radio — radio in the 3.7-gigahertz (GHz) to 6.4-GHz frequency range. Unlike earlier programming, the provider’s broadcast is completely digital, which means it has much better picture and sound quality . Digital broadcast satellite transmits programming in the Ku frequency range (11.7 GHz to 14.5 GHz ).
There are five major components involved in a direct to home (DTH) or direct broadcasting (DBS) satellite system:
•Programming sources are simply the channels that provide programming for broadcast.
•The broadcast center receives signals from various programming sources and beams a broadcast signal to satellites in orbit.
•The satellites receive the signals from the broadcast station and rebroadcast them to Earth.
•The viewer’s dish picks up the signal from the satellite and passes it on to the receiver in the viewer’s house.
•The receiver processes the signal and passes it on to a standard TV.
