The Improved Technology Of Satellite TV System
The number of people using satellite TV system has increased since its emergence into the market in the early 1960s. The technology behind it has also advanced a lot since the “Early Birdâ€, one the first commercial satellite TVs. This TV had very poor pictures of low quality as compared to the present day crystal clear Direct-to-home deliveries available on Satellite Television.
Satellite TV operates by communication between a satellite dish, a set-top-box and the international satellite station in space. Signals are sent through an elliptical geostationary orbit which is located at about 37, 000 km from the surface of the earth. The full communication process begins when an uplink station sends signals via a powerful dish network antenna.
The signals are directed towards the geostationary orbit of the satellite. Upli9nk station dishes are large in diameter so that they increase the accuracy of the signals received by the orbiting station. After this, transponder station retransmits the signals back to the satellite TVs on the Earth.
As a result of the evolved technologies and emergence of new ideas, quality of reception has improved over the years. Early, the images on TVs were of low quality and were subject to atmospheric interference. And as technology continued to improve, new better solutions were invented. The use of parabolic dishes assisted in improving the strength of the signals. In the early days, sound and images were not in fine resonance. But later the satellite TV gurus invented a low noise amplifier which they use to tune the accompaniment of sound and images.
The other parts that have contributed to the changes in Satellite TV in a big way are the fall in prices of equipments used and the expenses of installing the whole system. As an example, the change from C-band TV systems to the current satellite systems has reduced the connection to UHF TVs and its now possible to watch more than one channel from the same one connection line. This has assisted in mass production in terms of connections and equipments used.
As the digital quality technology has gained publicity, the satellite TV has also gone digital. This is a great improvement as compared to the old PAL and NTSC technologies. These improvements have made many people to subscribe to the satellite TV systems, therefore moving always from the traditional analog TVs. As opposed to those days when people thought that those who had satellite TV were rich, these days all people from all walks of life can have the connection as well.
