In Pingtang County, Guizhou Province, China, there is a huge radio telescope with an area the size of 30 standard football fields.
This giant device has a vast reflective surface, which can not only be used to observe the universe and understand information from outer space, but also to receive signals from outer space.
Compared with this behemoth, everyone should be more familiar with its "siblings", that is, the "satellite pot".
When it comes to satellite pots, many people will recall the experience of watching TV in the past, and they miss it very much.
In the period of rapid economic development of the country, people's needs are no longer limited to basic life, but gradually shift to the pursuit of spiritual enjoyment and cultural entertainment.
As an important form, television has become an indispensable way for people to obtain information, entertainment and relaxation.
However, with the development of technology, the instability of TV signals has become a common problem, and there are often situations such as blurred screens and no signals.
In this case, satellite receivers quickly came to the fore, which is what today is called "satellite pot"!
It's cheap, powerful, and only takes a few minutes to install, making it an ideal choice for people's TVs.
When there are snowflakes on the TV screen and the picture is not clear, simply adjust the direction of the satellite pot to restore the clear picture.
What's even more interesting is that we can receive a variety of different programs from distant Taiwan channels and even foreign channels through satellite receivers.
In this way, the satellite pot is very convenient and practical, so why is it disabled?
First of all, we want to understand how the satellite pot works, which involves the process of receiving and decoding the signal.
When TV signals are transmitted to the earth via satellites, the satellite receiver is responsible for receiving these signals and decoding them through the device, and finally converting them into a picture that we can **.
Compared with other tools, it is affordable, convenient, and has a strong ability to receive signals, and can collect some channels that cannot be covered by cable TV, even including foreign variety shows.
However, with the continuous advancement of science and technology, especially after the emergence of new communication technologies, the satellite pot began to show some problems.
First of all, it is greatly affected by the weather, and bad weather conditions may lead to unstable signals and affect the ** experience.
Secondly, the maintenance cost is high, and it needs to be adjusted and repaired regularly, and the user will face more expenses and troubles.
Furthermore, the use of satellite receivers involves legal and copyright issues, particularly when receiving foreign telepaths.
Finally, the technical defects are large, and in bad weather conditions, some poor-quality satellite receivers are prone to problems and become essentially "lightning receivers".
It is precisely because of these problems that many countries and regions have begun to consider disabling satellite receivers, including China.
In addition to promoting the development of a new generation of communication technology, the move to ban satellite receivers may also be aimed at regulating transmission behavior and protecting intellectual property rights.
So now, you know why the satellite pot was banned.
