Recently, the topic of TV charging has been very hot.
When people are still bothered by a few minutes of boot advertising, probably few people will remember that there was a kind of "satellite pot" that became popular all over the country more than ten years ago. Not only can you buy it out for a lifetime for a few hundred dollars, but you can also see the TV stations of most countries in the world, which are so powerful that even the cable data transmission technology (that is, cable TV, which people often say) that the country vigorously developed at that time was almost deflated.
To this day, many friends have not really figured out why the "satellite pot" was strictly banned back then? There are still people who remember its powerful functions. As for what it can see, why it rises and why it disappears? After reading these knowledge points about it, you will naturally understand!
1. The largest satellite receiver
Speaking of "satellite pots", we have to talk about satellite receivers.
China's largest "satellite pot" is the "China Sky Eye" radio telescope in Guizhou, which is the world's largest single-antenna radio telescope, an area the size of 35 football fields. In addition to observing the extraterrestrial universe at ultra-long distances, it can also receive information from space. It can be said that it is one of the most bullish "alien signal receivers" of mankind at present.
Since they are all satellite pots, the principle of "China Sky Eye" is similar to that of the "TV Satellite Pot" erected on the roof. They all receive information through reflected signals. The larger the aperture, the stronger the received signal and the higher the playback quality. The difference is that the "satellite pot" receives a television signal, while the "Sky Eye" receives radio waves from the universe.
2. The "satellite pot" that was born out of thin air
The appearance of satellite pots is no accident.
At the end of the last century, China's economy ushered in rapid development, not only the material life was constantly satisfied, but also the "heartthrob" TV set in the spiritual market became more and more important. But the TV signal at that time was not good, it would take a station at every turn, there was no signal, and even in order to receive the TV signal stably, almost every TV would be paired with a signal receiver called "antenna", which was very inconvenient.
In order to solve this contradiction in people's livelihood, the state has developed cable data transmission technology (which is often referred to as cable television). However, this requires a large number of fiber optic cables for wired data transmission, and China is too big, and many places can only wait for the slow construction of fiber optic cables if they want to enjoy the signal.
"Satellite pot" appeared at this time of scarcity,With cheap price、Powerful functions、Simple installation、Immediate effect,Soon seized most of the Chinese TV market,It is no exaggeration to say,In the countryside at that time,"Satellite pot"It is almost the standard configuration of one per household。
3. The powerful function of "satellite pot".
The implementation principle of the "satellite pot" is different from that of the optical cable, a bit like the current "Starlink", which does not require the access of physical optical cables, but is just a mini-version of the satellite receiving station, which is composed of a parabolic antenna, a feed, a high-frequency head and a satellite receiver. The function of this "pot" is the same as that of the human ear, which can gather the information sent by the satellite, and then decode and translate it through the high-frequency head, and finally display the various channels that the people can watch on the TV.
Before that, watching TV was not an easy task in many rural and even remote mountainous areas. The black-and-white TV set is equipped with a small antenna, and it can only receive seven or eight sets at most, and the central set plus the provincial TV station and the local city TV station, when the signal is not good, there are all kinds of snowflakes on the picture, and the sound may also be mixed with noise.
Although the shape of the "satellite pot" resembles a large cauldron, the price is very low, generally less than 500 yuan. And once installed, you can watch hundreds of TV channels once and for all without paying any fees. Because of its very powerful viewing function, high practicality, and low price, the "satellite pot" was once a blessing for people in remote areas who could not access the cable TV network, and almost became a must-have "furniture" for farmers.
4. What can you watch in the "satellite pot"?
Around 2008, the popularity of household appliances in the countryside also made the "satellite pot" usher in a highlight moment.
It can not only receive the full set of CCTV and provincial stations, but also watch a lot of foreign TV stations. This has opened up new ideas for many remote villagers, and many countries do not prohibit some films, and it is very likely that a movie with color will suddenly be played at night.
Do you think that's enough? No, no, no, one day when there was no one at home, my brother quietly went into the house to watch DVDs, and the next-door neighbor also used a satellite pot, and he could actually receive the DVDs played at my house, and it is said that he told my dad at the time. There is a family in the village who spent a lot of money to buy a large "satellite pot", and it is said that they can search for all the color videos shown by the video camera in the surrounding two kilometers!
It's a pity that I was still a child at the time, and I only remember that the "Satellite Pot" could watch many children's channels such as Golden Eagle Cartoon, Xuandong Cartoon, and Kaku Animation. This made me quite uncomfortable for me, who was used to waiting for commercials for several days, and I never thought that there was a TV station in the world that was specially made for children, and it was a pleasure to watch it every day.
5. Satellite tuning is also a technical activity
Of course, not everyone can see it. Tuning satellite TV stations is also a technical job. A certain amount of skill and knowledge is required, and attention needs to be paid to angle and height adjustment during installation to ensure that the strongest signal can be received. Pressing the remote control indiscriminately will definitely not work, the network was not developed in those days, and the technical work of adjusting satellites was passed on by word of mouth. One of the eldest brothers in our village is a professional ginseng master, and he charges 50 yuan for a TV station, which was not cheap in those days. You have to make an appointment in advance, otherwise you won't be in line at all.
Different pot lids are facing different feelings. Even the weather changes will affect the changes of the TV station, maybe it is still Xuehua TV during the day, and the energetic programs suddenly appear at night, among which the adults' favorite is Hong Kong TV's Star TV, Phoenix Satellite TV and so on.
From more than 60 degrees east longitude to 169 degrees east longitude, film and television, news, adult ...... I heard that South Korea has the most adult channels, sometimes you can see five, and then the TV signal on the Russian side is also more unrestrained. There are also Indian TV stations, Middle Eastern TV stations, all in Arabic, and I often see these foreign TV stations broadcasting war news, although I can't understand it, but I will stare at the video for a long time.
6. Why is the "satellite pot" banned?
Seeing this, you probably know why it's banned, right?
After all, the political situation of each country is different, and the review of TV programs is naturally different, especially at that time, the influence of TV stations was no less than that of the current Internet.
The emergence of such loopholes will naturally be subject to strong supervision. In particular, many illegal columns have also begun to take advantage of the void, and long-term viewing will affect people's spirits and increase the pressure on law enforcement departments. Therefore, the ban on satellite pots began to be put on the agenda early.
Moreover, even without these strange foreign TV stations, the emergence of a large number of "satellite pots" itself has intensified competition in the radio and television market. In order to maintain fair competition in the market, after completing the coverage of optical cables, the state basically adopts a prohibitive and standardized attitude towards "gray area" equipment and services such as satellite pots.
7. "Satellite pots" are mostly three-no products
"Satellite pots" are almost all "three-no products".
Not only is the quality uneven, but it is also hung on high places such as roofs, high walls, tree trunks, etc. Long-term exposure to wind and rain will cause problems, increasing the danger to people passing by. Moreover, as a metal object and placed in a high place, the satellite pot is like a "lightning receiver", which is also dangerous during thunderstorms.
And its ability is too strong, you must know that every satellite pot is like a small information receiving station, many criminals will use the satellite pot to transmit information to each other, and it is also very difficult to be detected. And this large number of unauthorized TV signals are received, which can also have a negative impact on teenagers.
epilogue
Nowadays, the development of information technology has been turned upside down, and cable television has been declining under the impact of the Internet. More exciting, flatter stranger socialization continues to seize people's time, and even if the "satellite pot" is allowed, it is difficult to reproduce the previous pomp, and those who have not experienced that special era may never be able to feel the madness it once was.
What do you think? It's not easy to create, welcome to pay attention.
