How to change the parameters of satellite TV receiver

Since the upgrade of Zhongxing 99 satellite, some cottage phones can't be upgraded automatically when turned on. Just tested them with a garbage machine. Automatically searched to 39% after booting, and then crashed. Remote control failed to exit. Note that this is not a crash. Unplug the signal line and the automatic search is completed. Because there is no signal search, the search shows that 0 TV sets +0 programs have been found. At this time, you can use the remote control, and the receiver is in a state of no program. Then, connect the signal line and manually search four groups of transponders. Please note that this must be done manually. Automatic search will crash again. After the manual search is completed, the receiver can resume normal operation. You can try!

New Year's Day is approaching, and it is circulating on the Internet that Secondary Nine School has been upgraded. Genuine computers can continue to watch 45 TV programs, while shanzhai computers can't receive TV programs because they can't be upgraded, becoming electronic waste. Recently, the genuine China Nine Machines have been upgraded in the air one after another, further preparing for the counter-production after New Year's Day. It seems that this storm will soon destroy the cottage market. The ancients said, "I don't know the true face of Lushan Mountain, but I was born in this mountain." When you jump out of China Nine Machines' thinking and stand on the position of international standard receiver, you will feel how ridiculous it is for China Nine Machines to upgrade and attack the cottage. The reason for this is the following：

1. Every village in Secondary Nine is free to broadcast. The genuine machine is actually a free machine, and the cottage machine can be seen because the signal is free.

2. The circuit hardware of the cottage is the same as that of the genuine computer, and the viewing principle is the same. Upgrading from Secondary Nine cannot change the hardware structure.

3. Upgrading is just calling the internal functions of the machine. The first two upgrades are called "automatic search" function, and the software of the cottage machine and the genuine machine is the same. Since the broadcast mode is the same as the software and hardware of the machine, the upgrade of Secondary Nine is not terrible.

Let's review the actions before Secondary Nine: 10 On June 28th, Secondary Nine compressed four transponders into three, and called the "automatic search" function, so that both the cottage and the front-end can be upgraded. 65438+February 27th also calls the "automatic search" function, but the difference is that the upgrade date of the genuine machine software version is changed to 65438+February 27th. We can't know what instructions the satellite signal sent to the receiver at this moment, but the notice of the Radio and Television Bureau revealed Zhong Jiu's countermeasures. The first frequency point is used to identify the genuine machine and mark it, while the cottage machine is not marked. After New Year's Day, the PID codes of program audio and video changed, but several ethnic channels remained unchanged. The marked genuine machine calls the "automatic search" function and can be viewed normally. The unmarked cottage machine does not call the "automatic search" function, and the PID code of the original program remains unchanged, so it can only receive minority channels with the same PID code, thus achieving the purpose of attacking the cottage.

However, cracking is also simple. If you can't search automatically, you can search manually. If not, you can brush the software of the genuine machine. Form 9 upgrade is nothing to be afraid of. Finally, a senior radio and television company that advises cottage manufacturers not to be useless. Radio and TV can't wait for cottage manufacturers to study cracking methods until they close down. How can they care about manufacturers like gorillas? If they really care, don't upgrade? As long as it is not encrypted, there is nothing to worry about in the cottage. Once the original encryption and the cottage are finished, if the secondary nine upgrade can reach the cottage, there is no need to add CA encryption system to the second generation machine. Form 9 upgrade is just to scare people. The cottage machine is not afraid of upgrading, and it is with the genuine machine. Let the upgrade of Secondary Nine come more violently!

From the perspective of home appliance maintenance, you can continue to watch the free program of Zhongxing 9!

1. There is no possibility of automatic upgrade. I really don't know how some people come up with it, just to scare people who don't understand. Any satellite antenna is not a computer, just like a DVD. The chips that decode signals are all hardware and cannot be upgraded. Have you ever seen a VCD upgraded to a DVD after installing a certain program? This is a joke. Although there is an adjustment plug at the back of the machine, it is the interface for firmware adjustment, and its function is limited to the information storage of program number. Have you ever seen a satellite machine enter a cracking program through this interface and receive an encrypted radio station? Jokes.

2. In the past, satellite adjustment was not encryption at all, but the adjustment of program location. But the automatic search on the machine can't be completed only because the locator marked 1 is gone, so the search can't be completed. Don't be scared by this!

3. Everyone must correctly understand what encryption is. No matter what kind of encryption it is, it is just a form of re-editing the signal. Because the decoded chips are all hardware that cannot be upgraded, there are only two schemes to upgrade encryption. One is to replace all computers, and the price is too high for anyone to do it. The second is to change the card, which is an important reason for the charging machine to insert the card and is conducive to management.

4. zhongxing 9 should have been encrypted, and now the so-called encryption should come from here, but it has been spoiled by some people. Considering more than 3 million genuine users, free programs will be free, not less. The second generation computer will watch encrypted programs in the form of plug-in cards.

There are three ways to upgrade and crack the ABS live broadcast machine on ZTE 9: 1: air upgrade. 2 yes: upgrade by computer. 3 is: machine-to-machine upgrade.

The first method is that the fake goods are worse than death. Maybe the landlord's method is feasible, which depends on the situation after the upgrade on the 4 th. I hope it works.

The second method is to upgrade by computer, but you must have the corresponding software and parameters. If you upgrade again in the future, you must refresh your computer again. More troublesome.

The third way is that you must have a genuine machine.

The symbol rate of ABS special machine cannot be modified manually, but only by software. In fact, the air upgrade is to update the software of the set-top box. If the symbol rate is changed, the aerial upgrade of pirated machines will not be completed, and neither will the landlord's method. Only through the second and third methods, it is impossible or difficult for ordinary users to achieve.

Zhongxing 9 upgrades to crack down on "cottage pot"

2009-02-23, 65438 According to informed sources, with the end of the second phase bidding of Zhongxing No.9, the encryption channel of Zhongxing No.9 village platform will be officially tested from 12-26, and it is expected to be encrypted around 20 10 New Year's Day. This opened the contest between SARFT and 30 million illegal set-top boxes that entered the market.

The bidding for the second phase of Zhongxing No.9 started on June 2 1. Compared with the first bidding in 2008, the number of bidding equipment increased from 3.66 million units last year to 8.65 million units this year. The tender amount has also increased from 654.38+04 billion yuan to 3 billion yuan; The number of successful bidders increased from 7 last year to 15 this year. It is estimated that by the end of next year, there will be 716,000 radio and television villages with more than 20 households electrified.

30-40 million "black boxes" flooded the market.

The village-to-village communication project of Zhongxing No.9 mainly serves farmers and herdsmen in remote areas of China, providing 48 TV sets and dozens of radio programs for areas where cable TV coverage is difficult. The 3.66 million sets of satellite receiving equipment tendered in the first phase covered 24 provinces in China. During the implementation of the first-phase tender, a large number of audio and video decoding chips used by Zhongxing 9 receiver flowed out, resulting in a large number of underground "black boxes" flooding the market. According to unofficial data, at present, there are about 30-40 million sets of underground "black boxes" in Zhongxing 9.

Because the signal of every village of Zhongxing-9 satellite can be easily received by antennas of 45cm or even 25cm in most parts of the country, and the price of "black boxes" is generally lower than that of 200 yuan, nearly 40 million sets of underground "black boxes" have caused great pressure to cable operators everywhere. The number of digital TV conversion and subscription of cable TV users has seriously affected the interests of cable TV operators in some areas. It is understood that in some areas where "black boxes" have seriously affected cable TV, the number of cable TV users has decreased by 20-30%.

654381October 26th, during the ICTC (International Transmission and Coverage Seminar), Zhang Haitao, deputy director of the State Administration of Radio, Film and Television, publicly stated that the "black box" market for live stars had a great influence on cable, and the State Administration of Radio, Film and Television was stepping up efforts to rectify the underground market.

The second phase of 9 is all encrypted.

At the appeal of all parties, the encryption mode was decided at the beginning of the second phase of ZTE No.9 bidding. However, due to the free mode of 3.66 million set-top boxes in the first phase, in order to ensure the interests of 3.66 million free set-top box users in the first phase, the encrypted clean (free) mode was decided in the early stage of the second phase of bidding. Set a satellite transponder for the second phase of the set-top box to transmit encrypted signals.

Since 10 and 1 1, Zhongxing No.9 has partially adjusted the frequency band of the original phase to prepare for the second phase of the encrypted channel. The number of satellite transponders has been reduced from four to three, and the channels have been recompressed to provide users with 46 sets of TVs, 4 sets of radio programs and other information services.

Because the design of the satellite set-top box of Zhongxing 9 adopts the way of air upgrade to upgrade the box system (the upgrade signal is included in the satellite signal of Zhongxing 9, and the receiver will automatically upgrade the built-in software when it receives the signal containing the upgrade content). Therefore, the satellite transponder adjustment of 5438+ 10 June did not have any impact on the users of genuine set-top boxes. Genuine users can watch TV programs normally after turning on their mobile phones for a few minutes. Nearly 40 million sets of "black box" users are a false alarm. Because most "black boxes" don't have genuine serial numbers, they can't be upgraded in the air normally, so they can only search for signals manually to achieve the purpose of watching programs normally.

It is understood that the encryption system in the second phase of the 1990 s adopted the conditional access system of NDS, a subsidiary of American News Group. As the first broadcast network security solution launched by CCTV Digital TV, NDS has mature experience in the operation of tens of millions of users. However, domestic CA (Conditional Access) vendors missed the first encryption. However, according to Sohu IT, some domestic CA manufacturers are also actively contacting SARFT. Domestic CA is very likely to be shortlisted for the multi-CA system synchronization project of Zhongxing No.9 (the same channel signal is encrypted and broadcast by different encryption systems at the same time), which makes the domestic TV program broadcast safer.
