Emerging Technology Of Satellite TV System

By Dennis Jackson

Since the emergence of satellite TV way back in early 1960s, the trend has gained large usability among different users. Its technology has also undergone a series of metamorphosis since the days of "Early Bird" the first commercial satellite TV which was characterized by poor picture quality to the present crystal crisp deliveries which is the norm of today's Direct-to-home satellite television.

Satellite TV works by means of communication between a satellite dish, a set-top-box and the global communication satellite. The whole set communicates by means of signals sent by an elliptical geostationary orbit located about 37, 000 km away from the earth's surface.

The cycle of the satellite TV communication is a two part process. First, an uplink station sends powerful signals to the satellite geostationary orbit via a dish network antenna. The surface of the uplink station dish is large because this increases the preciseness of transmissions to the orbiting stations. After this, the transponder relays signals back to earth which are then seen in the satellite TV.

Due to the evolving technologies and new ideas, the quality of satellite TV reception has tremendously improved over the years. Initially, the images were of low quality and were largely affected by atmospheric conditions. As newer technology remedies were invented, there came such equipments as parabolic receiving dishes which were a solution to weak satellite signals. Earlier, the sound was not in fine resonance with the images. However, later on satellite TV experts came up with low noise amplifier to tune in the sound-image accompaniment.

Another aspect that has changed about satellite TVs is that the costs of equipments and the expenditure of installation have tremendously gone down. This is due to the cheaper alternatives that have been employed as far as technology is concerned. For instance, the switch from the C-Band systems to the currents satellite TV systems enabled cheaper connection to the UHF TVs and made it possible for viewers to view multiple channels from the same connection line. This in turn resulted to mass production in relation to the equipments and commercial connections.

Of late, further improvements of the satellite TV have been witnessed due to the rise of digital quality technology. This is a vast leap from the former standards like PAL and NTSC. The satellite TV has been fully digitalized. These improvements have seen subscriptions to satellite TV connections rise as opposed to traditional analog connection days. Before, satellite TV ownership was left to the rich elite but now, money has no bearing on whether or not one gets satellite TV connection.
