How satellite TV works

How signals are transmitted Satellite TV delivers television programs using signals transmitted through communication satellites. Television programs are basically audio and video signals. These signals are transmitted from space. Satellites in space are referred to as geostationary satellites. Signals from space are received through a satellite dish back here on earth. These satellites in space have several transponders which facilitate the transmission of signals back to earth. These signals are usually on Ka Band, C Band, or ku Band which basically signifies the frequency of the signal. These geostationary satellites usually move around the earth hovering about 20,000 miles above the earth’s surface. The satellite dish acts as the collector and reflector of those signals from space. This is because the dish collects the signal and reflects it to a device known as a feedhorn. The feedhorn then sends the received signal to the low-noise block down converter (LNB). The LNB converts the signal to a more suitable frequency for transmission over a cable. Apart from that, the LNB also amplifies the signal. This cable via which the signal is transmitted is known as the IFL. LNB transfers signal over to the IFL then to the satellite receiver. Then, the satellite receiver sends the signal to the television set. Satellite TV services. Satellite TV offers a wide range of services and channels, especially to geographic areas that terrestrial televisions or cable televisions are scarce. Satellite Television technology is gradually developing and is now a popular choice for television viewers. Digital satellite TV Digital satellite Television is a form of encoding for most satellite TV. As a homeowner interested in subscribing to this service it requires purchasing a satellite dish which you will place outside to pick signals, and deliver them to your television. Subscribers can receive all major premium channels and national channels. Satellite TV is accessible in ATSC High Definition and the standard resolution format. The digital signals move at the same time with the earth so that they remain the same position with earth’s satellites. This mechanism is referred to as geosynchronous. Signals are sent to the geostationary satellites from the broadcaster center, and then sent to the subscribers’ dish. Digital data is compressed with MPEG-2 or its variation, but MPEG-4 has already begun replacing MPEG-2 in some satellite networks. The purpose of the receiver The key piece of equipment is the receiver, because a code is sent from the satellite which happens to be encrypted. Without this code, people would be buying black market satellite dishes, connect them to their television, and receive free television service. Satellite TV options Satellite Television subscribers receive local stations from Satellite Television Company.  However, your choice for satellite Television will depend on what country you live in. In some large cities, spot beam services are available. Spot beam is offered in the UK. It was developed to offer marketing services to satellite industry businesses. Dish network is an American service provider. Dish network provides audio programming, satellite internet, satellite television, and interactive TV services. Another satellite vendor is DirecTV. It is a service provider based in California. It transmits digital satellite TV and audio in the United States and in the Caribbean. Dish network and DirecTV programs operate on the Ka and Ku bands. Free to air satellite television channels are also available if you have a free-to-air receiver. In the early years, Europeans and North American television viewers had to wait for days in order for their viewing tapes to arrive via ship. In the 1950s, there happened to be a tight space race between Russia and USA. Sputnik was the first satellite to go round (orbit) the earth, and 1957 marked the day it was launched by Russians. Six years later, the first satellite communication was launched.
