How Does Satellite TV Work

Jan 29, 2008
Satellite TV is transmitted by communications satellites, unlike cable TV. Satellite broadcasts provides a broader range of channels and packages than cable or terrestrial T-V as it oftentimes supplements older terrestrial signals. It also provides subscription only services.

When Satellite television for the first time came in the market, the dishes used at home were huge and expensive. Back then only the most ardent viewers went through the trouble of installing that huge metal device and the expenses that came along with the process. It was tougher to watch Satellite TV as compared to cable or broadcast.

It is a different story today. There are compact little satellites available now, and most houses have them.

Satellite TV consists of a wireless way of transmitting television programs to your home. This is done with the help of a radio signal. In broadcast television, powerful antenna is used to transmit radio waves all around itself and much smaller antenna are used by the viewer to pick up these signals.

The signals come from the bigger antenna in a straight line, so the smaller antenna have to be in direct line with it in order to receive the radio signals being sent. This is a problem. Satellite TV solves this problem by sending the waves from satellites which orbit the earth. By being in the sky instead of on earth, they are able to target many more viewers. Specially made antennas called dishes or satellite dishes send the radio signals to viewers on earth.

The story of the satellite is not new every time technology surges ahead, a new development is made. When cable television only allowed about 30 channels, satellite broadcasts revolutionized the TV world with 3000 channels and various packages offered. This is all because the line of sight problem was solved through orbiting satellites that could reach a lot more people.

Today, there is something that connects everyone on earth. Billions of people use it everyday to connect to each other over the globe to talk, to do business, to trade, to exchange news, and do a lot of things besides, things which were not possible, and could not have been possible without this world wide connection. This revolution is the Internet.

While satellite television can reach a lot more people than cable television can, Internet TV goes one step ahead by being accessible to anyone with an internet connection. Channels from all over the world, internet-only content, free downloads, video on demand, access to virtually any T-V show, sports and news. Internet television is the next logical step after satellite TV. Just like satellite programs once created a whole new era, Internet TV looks set to create one as well.

With Internet television you do not need any extra software downloads and you do not need to purchase any new hardware. All you need for good viewing is a high-speed internet connection. There is a huge amount of content available, including all your favorite things on regular programs and much, much more. Like satellite TV gradually replaced cable TV as a part of everyones life, Internet television looks geared to do so too.
