Satellite TV was first launched in the market in the early 1960s. Since then it has undergone numerous alterations. The usage of the satellite TV has risen in popularity since the launch of the "Early Bird" which is the first commercial satellite TV. It was plagued with poor quality of the picture unlike the clear delivery that is experienced today's satellite television transmitted straight to the consumer's home.
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.
Further improvement has been seen of late due to the emergence of digital quality technology. Satellite TVs have gone digital too. This is an improvement to the previous standards like PAL and NTSC. All these improvements have lead to more people subscribing to satellite TV connections as opposed to the traditional analog connections. Contrary to sometimes back where people with satellite TV connection were considered as rich, nowadays this phenomenon has no imperative on the amount of bucks you have.
