I believe that many people have experienced such a stage when they watched TV when they were children, from installing antennas - installing large "satellite pots" - installing small "satellite pots" - installing cable TV.
So why is it nowDisable Satellite CookerThis? There's one reason for thatThere's so much to seeFinish.
Satellite pots are being installed.
What is a "satellite pot"? Why is the "satellite pot" favored by the public? What are the reasons for the ban on the "satellite pot"? And what is after the "satellite pot"? Today we willLet's find out, this "satellite pot" that we underestimated,What can you see?
Satellite pot "Actually, it isSatellite dishes, is oneA metal parabola that resembles a cauldron。It can reflect the weak satellite signal to the feed located at the focal point, and after the feed transmits the collected energy and signal to the high-frequency head, the high-frequency signal can be received and demodulated to the best information.
So in general, the antennaThe larger the caliber, receivedThe stronger the signal, the more TV shows that can be **. In terms of the number of received signals, it can be divided into:Forward and partial feeds
Forward and partial feeds of satellite pots.
The forward feed is the first cauldron to be installed, and it receivesC-band programming。The C-band can satisfy usWatch all the channels in the country, and some famous foreign channels, such as CNN, BBC and NHK, etc., and almost all of them are free**. And the partial feed is the small pot, which is receivedku program, the number of programs is not as much as that of the C-band, like the rural areas that were popular before"Village-to-Village" and "Household-to-Household".What is used is partial feeding.
The commonly used household communication in rural areas is partial feeding.
Generally speaking, it is possible to receive free programs that can be achievedMore than 60You can also pay to see itMore than 200。Like the "Household Pass" three-generation machine canWatch 58 programs for free
Satellite pot "in the ** decade can be said to beAll the rage in the countryside, almost at the door of every house, the existence of "satellite pots" can be seen on the roof. Before the birth of the "satellite pot", weAntennas are used to watch TV。Generally, several wires are tied together and bamboo poles are used to support the roof to receive signals. This kind of antennaThe stability is not high, so the received signal is also unstable. And basically one antenna is enoughOnly one program can be received, there is absolutely no way to meet the demand.
Ancient antenna to watch TV.
As a result, the "satellite pot" that can receive multiple program signals came into being, and the cost of installing the "satellite pot" at that time was not high, and it was probably needed200-300 yuanWell, the key is that you can install itFree to use for life, you say it doesn't smell good.
The shift from antennas to "satellite pots" allows people toFrom watching a few shows to hundreds。Many people choose a cauldron that can receive more TV signals at the beginning, so to speakYou can watch whatever you want。Like thisAffordable and convenient "satellite pot".Naturally, it is favored by the public.
The satellite pot was indeed "very fragrant" at that time
"Satellite pot" provides for people's entertainment lifePlenty of options, andGood value for money too, why should the countryProhibited UseWhat about the "satellite pot"?
The state has severely cracked down on the illegal use of "satellite pots".
country for nearly twenty yearsThe illegal use of satellite ground reception facilities has been cracked downIn 1993, the first order No. 129 "Regulations on the Management of Satellite TV Broadcasting Ground Receiving Facilities" was adopted, which was revised in 2013.
Operation Extinguish the Pot.
Article 8 clearly stipulates that individuals shall not install and use satellite ground receiving facilities. If there are special circumstances, you need to go through layers of approval before you can use it.But despite this, there are still a lot of peopleUse and sell "satellite pots" at the risk of being penalized。As mentioned earlier, at first people were more willing to use large "satellite pots", but because of itThe footprint is too large, and in the case of the country's crackdown on "satellite pots", many people replaced the big pot with a small one.In addition, Article 10 also mentions the relevant penalties for violating the provisions: those who install and use satellite ground receiving facilities without authorization shall be confiscated by the administrative department for radio and television and may impose a fine of up to 5,000 yuan on individuals and 50,000 yuan on units.
Numerous satellite cauldrons were destroyed.
In order to be able to implement the crackdown on the phenomenon of "satellite pots", many localities have tried all kinds of methods. One of the reasons why many people are reluctant to change the "satellite pot" isThe cost is small, if it were re-establishedCable TV is installedThat's another expense.
So in 2015 in Zhangzhou, Fujian, based on these reasonsLaunched the "Love Replacement" campaign, by helping villagers install cable TV for free to dismantle the "satellite pot". * Helped villagers dismantle more than 2,000 "satellite pots" and installed more than 2,400 cable TV stations, which were successfully established14 "No Pot Demonstration Villages".
Cable TV is being installed for villagers.
Problems with the "satellite pot".
In fact, it is not unreasonable for the state to ban the use of "satellite pots", we have actually discovered it in the process of using itLots of questions。These questions mainly relate to:Signal safety issues, personal safety issuesWait.
Information Security Issues
Signal security issues, one is what we receiveThere will be problems with the signal, and the other will appearIllegal Transmission of Signalsand so on.
Signal is key.
As we mentioned earlier, the "satellite pot" can receive a lot of TV programs, and this will appearThe complexity of satellite signalsWe have no control over the TV programs we receive.
In particular, the large "satellite pot" can receive not only domestic TV programs, but also foreign TV programs. Compared with foreign TV programs, domestic TV programs are indeed safer, but there will still be some TV programs that do not meet the standards. And there will be a lot of foreign channels receivedRelatively large-scaleTV shows, such as:Violent, bloody, pornographicWait. There will be some of themThere is no lower limit, and the three views are destroyedTV shows.
Numerous foreign channels.
For example, the BBC once had a first gear"Bad History".The show shows a white man dressed as an ancient woman, and she shows everyone thatDiet in the Tang Dynasty, but in fact, she ateCockroaches and mice。The key is that this show is still oriented toChildren, it can be said that her purpose in doing this is nothing more than to let foreign children grow upMisunderstanding of Chinese history
Foreign channel program - "Bad History".
There is also a TV show that has been popular since the 90s"The Morrie Show"., the content of this show canWith no lower limitTo describe, very ruined three views, often involving like".A pair of twin siblings actually have two fathers".
These TV programs are often received into the TV by the "satellite pot", our countryAdolescents and children** Television has the highest frequency, so there is often a chance to be exposed to such a picture, which will have an impact on themMental health takes a serious toll on it。And we know that a lot of times children are often being used when they are on TVImperceptiblyimpact. Some of the children's values will still beShaped through TV shows, they are susceptible to foreign cultures, most likelyFacing the problem of cultural invasion
Teenagers and children receive ideas through television.
In addition to the bad signals we will receive, there are many moreBad actors will use a certain technology, using the "satellite pot" will be someConfidential content involving ***Transmission to foreign countries will also cause serious harm to China's information security.
Personal safety issues
Our personal safety may also be affected when using the "satellite pot", which is mainly installed at homeSafety hazards。In rural areas, many people will put the "satellite pot" in order to facilitate the reception of signals, or when there is no open space on the groundThe corner of the roof。Whether it is a large pot or a small pot, there is a danger of falling from above.
If placed in a corner, it is easy to fall from a high altitude and hurt people.
Anyone who has installed the "satellite pot" knows itsThe bottom will rust in the sun and rainAfter a long time, encounteredWindy and rainy weatherIt may fall, and if it hits someone, the consequences are even more unimaginable.
Rusty satellite pot at the bottom.
And the "satellite pot" is veryVulnerable to lightning strikesIf the installation location is on the roof of the building or near the door of the home, it is highly likely to break the circuit evenIgniting a fire。This not only causes property damage, but also puts lives at risk.
With the development of technology, we are now able to install cable TV in addition to:Through the network ** TV。Many people think that it is more affordable to use a "satellite pot" **TV, but in fact it is now using a cable TVIt's also not very expensive, and there will be some affordable **. In fact, the most critical point is that cable TV will be better than "satellite pot".It's safer**10,000 Fans Incentive Plan
