Satellite television is still one of the least understood major technology providers for television reception worldwide, yet in the end it is a relatively simple technology based on relatively basic physical theories. Although many people are unsure of how the signal is received and reproduced on the television, that has not stopped lots and lots of people from signing up as new satellite customers. In fact, in recent years, given some advancements in satellite technology and improvements in service, a record number of viewers have switched from satellite television to cable or regular broadcast services, and virtually all of them have rejoiced. with the result – except perhaps for the eccentric customer who cannot tell when superior service is being provided. The truth is that satellite television is available to many, many more people around the world and always provides a service that is on par with or is superior to the best cable packages, and for those two reasons alone it is quite easy to understand. the growing popularity of satellite television services.
The tech aspect of all of this really isn’t that complicated, as mentioned above. The basic sequence of events is as follows: an uplink station transmits programming material in compressed digital format (contrary to the situation with many cable providers, satellite providers have long been digital) using uplink satellite dishes very large that are fed with enough power to improve the strength of the signal that is fired into space. These uplink dishes can reach dimensions of more than 30 feet in diameter, a quality that improves signal intensity and target, helping to improve the overall quality of service. Geostationary satellites in the sky: geostationary implies that the orbital period of the satellite is the same amount of time it takes for the Earth to rotate on its axis, which means that it is always on the same point on the planet: they have several transponders that receive the signal from the uplink satellite dish and retransmit it at a different frequency back to Earth for individual satellite television customers to decode and view on their television. The frequency of the signal is changed in the downlink segment to avoid interference with the uplink signal, which if that happened would result in inferior service, uncharacteristic of the industry and therefore not the case.
The satellite dish on top of a subscriber’s roof is at the correct angle to receive that downlink signal; Since the signal is quite weak after making the journey of many thousands of miles from the “bird in the sky” as satellites are known in the industry, satellite television dishes are concave (also known as antennas parabolic), which concentrates the signal. and it focuses it on a point, which is where a detector (called a feed horn) is placed to capture the newly concentrated signal and transmit it to a decoder and finally to a television where the sheer bliss of entertainment is inevitably experienced.
