Satellite Tv: The Use Of Science In The Field Of Entertainment
Satellite television broadcasting, or simply satellite TV, is a television service where the signal is relayed via a communication satellite to be broadcast to customers who have a satellite dish and set-top box as receiving equipment. This service is common in areas where cable or terrestrial television is not offered. One major difference of satellite TV from cable or terrestrial television is that it offers more channels and services.
In 1962, the first satellite TV signal was transmitted from Europe to North America via the Telstar satellite. In 1967, the first satellite TV network was created in the former Soviet Union. It was also in the region that the first direct broadcast satellite was launched in 1974. So this "new" television technology is not so new after all.
The technological development that had the most impact to the satellite TV system that we know today is the development of Direct Broadcast Satellite (DBS). DBS is also known as "direct-to-home" broadcasting. The development of DBS has allowed the television distribution of programming to homes with satellite dishes or mini-dishes. A dish or a mini-dish is an antenna that is designed to focus on a specific signal source.
Today, television programming gets to customers through what is called direct broadcast satellite providers. These providers are now capable of distributing virtually hundreds of channels to their customers. And since the broadcast is purely digital the quality of the picture and sound that emanates from television sets hooked up to satellite TV are far more superior to the quality of images from cable TV providers.
