What Is Satellite TV?

Satellite service can be defined as a service of broadcasting TV signals, in which subscribers directly receive signals of TV through a receiver unit having shape of a dish. Sending of this signal is controlled and monitored by a high tech communication satellite, which is present in its fixed orbit above the atmosphere of earth. Original signals get uploaded in theses satellites only, and then regulated sending of signals takes place from this main satellite to all linked receivers present at planet earth. Subscribers pay a certain amount to get an authority to receive these signals officially. Dish shaped receivers pass this signals to the TV, to display received programs.

Why satellite TV?
Satellite TV is a solution of many traditional broadcasting problems. In traditional broadcasting system, TV stations transmit signals free to air, which then directly received by users through installed antennas. These TV stations broadcast TV signals in two different bands of radio waves. These radio wave bands are- UHF (ultra-high frequency) and VHF (very high frequency). Now a user receive these signals by means of roof Aerial antennas or by means of antennas which are assembled with TV sets itself. But this broadcasting system was not able provide a clear appearance of the signals on TV screens, because it strongly depends upon the strength of the signal, distance between the transmitting station and receiving antenna and on various other climatic factors. Cable TV system is a very good alternative of this traditional broadcasting. But because of heavy work of cabling for proper distribution of signal, subscription of cable services is very expensive.

Earlier satellite TVs
Because of above mentioned problems, satellite TV broadcasting system appears to be much better option. Satellite TV is the solution of various broadcasting related problems. Satellite TV provides a service of strong TV signal, without any wires. But, traditional satellite TV systems were enabled with very large sized dish receivers, because technology of transmission and receiving was less developed in earlier times. But modern dish receivers are compact in shapes and they also have an attractive appearance.

Moreover, earlier dish receivers were direction sensitive. So to receive complete signals from communication satellites, it was a must to adjust these dishes according to standard points of the sky. This was very tedious for subscribers. As a result earlier satellite TV system was near to flop according to performance and service.

Modern satellite TV
Modern satellite TV is a much more advanced system of broadcasting. It fills all the flaws of earlier satellite services. Modern dish receivers are not bulky and heavy in appearances. They have very compact sizes; it’s very easy to install them and a small space is required to make a connection of the dish. For signal receiving these dishes use transmitted signal of geostationary communication satellites, as a result there is no need of adjusting angles of dish to get a continuous signal. Moreover, installation of modern dish systems is very easy and economic.

Those companies which provide services of satellite TV, they always have contracts with popular TV channels. So they claim a license to broadcast signals of all those channels which are in public demand, this feature enable all the subscribers to visualize free as well paid channels with extraordinary quality of signal. Moreover satellite TV companies also provide special services of requesting a movie or a repeat telecast of a TV program. In this way satellite TVs are introducing a new definition of signal broadcasting and entertainment.
