Satellite TV is a type of broadcasting service that allows the users to receive television signals by means of dish-shaped receiving unit. The television signals are first uploaded to the communication satellite that is electronically scrambled and prevents unauthorized downloading. These signals are received by those who have paid the subscription fee and users are provided with a descrambler and a receiving unit to receive the signals.
The actual tuning procedures are done through cables just like any other cable television services. Satellite TV is preferred more than other broadcasting methods to avoid traditional problems associated with other broadcasting methods. Normally, in traditional methods, the signals are received through the antennas in the user place. The signal is not clear in the traditional method because the signal strength largely depends upon the distance between the antenna and transmitting antennas, also various climatic factors affect the signal. In cable TV system, heavy cabling is done for transmitting proper signals and therefore it is very expensive.
Satellite TV is a better option when compared with these broadcasting services. This service is mostly preferred for its strong signal and also reduces the large amount of cabling. Earlier satellite TV systems had large receiving units. Today, advancements in the technology have reduced the size of the receiving unit and they have become compact in size. Also, these days satellite services are not direction sensitive like those earlier satellite services. The installation procedure is very easy and more economical. The quality of the signal is also greatly improved in the satellite TV services and these services are now introducing the new definition of entertainment.
