Satellite TV is TV delivered by way of orbiting communications satellites located 37,000 km above the earth's surface. To start a Satellite TV we have to locate a transmitting antenna at an uplink facility. Uplink satellite dishes go towards the satellite on which its signals are transmitted to & are very large in diameter, say about 9-12 meters or 30-40 feet. This large diameter gives a perfect positioning & a clear signal reception at the satellite. The satellite signals are retransmitted to Earth through transponders with a different frequency.
Satellite TV is much similar to the broadcast TV. Satellite TV is a wireless system for delivering television programming directly to a viewer's house. But in broadcast TV the major problem is of range because due to Earth's curved surface the signal line of site is broken many times. The other problem which broadcast TV gives is that there is much interruption in signal or the picture is distorted in the viewing area. Satellite TV solves all these problems of the range, broadcast signals, etc.
As due to Earth's surface the problem comes in signal but as satellites are high in the sky, the coverage scope for the customers is much more. They transmit & receive radio signals through satellite dishes which are a sort of specialized antennas.
The first Satellite TV was relayed from Europe to the Telstar Satellite over North America in 1962.Canada's Anik I, launched in 1973, was the first domestic North American Satellite to carry television. When Satellite TV was launched in the market, home dishes converted a lot of space in yards. Everyone was dying hard to have their own dish. Satellite TV has gifted today's generation with thousands of entertainment channels. They cannot imagine the tedious stage of people before the launching of Satellite TV.
Satellite TV is not only popular in America but it is equally popular in other civilized countries around the world. It is not only a channel but is actually huge information resource which is a source of entertainment as well as an important source of education.
Satellite TV is the best source we can rely on for entertainment. It gives us variety of channels some filled with comedy, laughter and drama, some of sports which take up each and every type of port, some on cartoons, some on news taking in view the news of both, national as well as international news and moreover the most awaited movie channels. Even for children it is not only that they give cartoon films but they also give channels of general knowledge and educative information like Discovery Science, National Geography, etc. Satellite TV gives us a gala gift of music channels where we can listen to all types of favorites. Recent independent searches carried out came of a conclusion that Satellite TV is a far more better option than Cable TV because it is better to install a necessary equipment without paying rental for it rather than pay rental for Cable TV, which too is very expensive& see disturbed transmission &that too limited.
There are 3 choices of Satellite TV available in America: DirectTV, Dish Network & Voom. To buy Satellite TV equipment, you have a number of retailers offering you various types of schemes also. To make comparisons among all the retailers just be online & nave all sorts of information in front of you. There is tremendous competition in retailers as the graph of popularity of Satellite TV is increasing day by day. Thus you can enjoy a selective choice of package according to the need of your family.
Tv Does Not Work
Satellite TV is another way of delivering television programming to the viewers. Satellite TV is a lot similar to broadcast television. Both of them transmit programming with the use of radio signals. However, there are some limitations to broadcast television.
Broadcast TV vs. Satellite TV
Broadcast stations make use of a powerful antenna to transmit radio waves to the surrounding area within a specific range. The viewers of broadcast TV have a smaller antenna to pick up these signals transmitted by the station.
However, the smaller antenna should be in the direct line of sight of the station's antenna to be able to receive a good signal. The signal received is also often distorted unless the receiver is very near the transmitting station.
Satellite TV companies, on the other hand, have a solution to the range and distortion problems of broadcast TV. Satellite TV transmits broadcast signals through satellites orbiting the Earth. Since these satellites are situated high in the sky, there are definitely more receivers in the line of sight of the transmitted signal.
How Satellite TV Works?
Satellite TV systems make use of satellite dishes which are specialized antennas to transmit and receive radio signals.
The communication satellites used in satellite TV are launched into space at about 37,000 km above the Earth's surface at the speed of around 11,000 kph. With this speed and altitude, the satellite can keep pace with the Earth's movement exactly which means it revolves around the Earth once every 24 hours.
The satellites are also in geosynchronous orbit which means they stay in a single location in the sky relative to the earth. Thus, the satellite dish needs to be directed at the satellite once as long as everything works fine.
Satellite TV starts with a transmitting antenna situated at an uplink facility. The uplink satellite dishes are directed at the satellite to transmit signals to as much as 9 to 12 meters in diameter. The bigger the diameter, the more improved the reception will be at the satellite. The signal is transmitted to transponders on-board the satellite, which retransmit the signal back to the Earth using a different frequency.
The satellite TV signal is quite weak due to travel in space. However, this signal, once collected by the parabolic satellite dish, is down-converted to a lower frequency band then amplified using a low-noise block down-converter, or LNB.
Types of Satellite TV Distribution
There are two primary kinds of satellite TV distribution, namely television receive-only (TVRO) and direct broadcast satellite (DBS).
Television receive-only satellite is a satellite TV reception device based on open standards equipment. This type is often referred to as the big dish satellite TV. TVRO systems more often use larger satellite dishes since a C-band setup is more common to owners of this system, although it is designed to receive signals both from C-band and K u-band satellite TV signals.
Direct broadband satellite TV is also known as "direct to home". DBS systems are also referred to as the "minidish" systems as it uses the small satellite dish that we commonly see around. This system uses the upper portion of the K u-band.
Satellite TV is getting more popular nowadays. It can be a good alternative to the regular broadcast TV or the more common cable TV.
