But How Does Satellite TV Work?

Satellite TV is coming of age and it's opening up television choice to everyone. It is popular and most of all, it is affordable. Whatever your needs are, there is a solution for you.

Satellite TV is great: the channels are endless and the freedom is also a plus. You can say it is a TV system in which the signal is transmitted to an orbiting satellite that receives the signal, amplifies it, and then transmits it back to earth. The signals are in digital format and require digital television sets not analog format. Satellite TV is a huge improvement over all types of Cable TV including digital. Digital signals picked up through the "Ku" band are MPEG-2 compressed video signals (30: 1 bits) which allows far more channels to be squeezed through without damaging clarity.

It's easy to get satellite TV, but keep in mind you do have to purchase the equipment from the provider or technology store unlike cable television that rents you the equipment for as long as you have service. You can picture satellite TV as simply another way of delivering multi-channel television. It is a complex, yet incredible way to enjoy your television viewing experience.

Digital Satellite TV

With digital satellite TV, digital transmission requires less bandwidth than analog transmissions because digital data can be compressed. Compression makes it possible to deliver the increased amount of data required for High Definition TV (HDTV). Digital satellite TV is in similar to traditional broadcast TV means it sends data signal to your home through the air in stead of radio waves.

However, the information is sent and received by satellite dishes, rather than smaller TV aerials, which are able to receive and transmit information from satellites orbiting the earth since you get a clearer, more direct signal than traditional aerial transmission. Digital picture and sound means a perfect picture on all your TV's, no grainy cable picture. With digital satellite TV, there is an on screen TV guide to see what's on, and instant detailed program information for the program you're watching and what channel you're on.

Digital switchover is almost upon us and that will mean that our old TVs just will not pick up signal anymore. One of the ways around this is to get a satellite dish installed and then watch TV through a satellite feed, rather than purchase an expensive new TV that can pick up the digital signal.
