Coquettish Rebirth

"What's the benefit of sponsoring this Ke Shouliang, our company?" Jia Gang and Su Ping, who were supposed to "go to the market for government affairs", asked strangely ().It turned out that the two of them were in the company, but when Ke Shouliang called the door to make an appointment to meet, Ding Sanshi reported it directly to Jia Hongjian instead of Jia Gang. Later, Jia Hongjian decided to meet Ke Shouliang out of curiosity. one side.As a young man, he naturally had to make up a random reason to meet him, but now Jia Hongjian explained to his parents what happened just now after seeing off Ke Shouliang.

"Now the two lines of our company - Huaxia Jahwa and cvd chips are in the stage of preparing for the outbreak and need a continuous exposure and publicity. If there is this Ke Shouliang's publicity, according to my personal estimate, it can be warmed up for half a year before the leap forward. After the project is carried out, there can be at least 8 months of continuous publicity time, which means 14 months. Our two companies are in continuous exposure. Such an opportunity cannot be exchanged for a few million or 1000 million. " Jia Hongjian said eloquently.

In fact, what he said was the truth. Ke Shouliang’s plan to leap over the Yellow River was indeed based on various warm-ups for about half a year. Even after the leap, the products of the relevant sponsors continued to be exposed for about half a year to eight months. Such an exposure time is not comparable to a simple advertisement. "And we can also share the expenses with Shuchuan Changhong. In fact, the cost is not too much..."

After Jia Hongjian's explanation, Jia Gang and Su Ping agreed.No matter whether they really agree with Jia Hongjian's judgment or not, even if it is complete, 1000 million yuan is not a big money for the Jia family. They would all agree, not to mention that now Jia Hongjian still wanted to achieve something in business.

On the second day, Ke Shouliang brought his lawyer to the headquarters of Huaxia Hi-Tech and signed a contract with Jia Hongjian and the others ().According to this contract.Jia Hongjian and their Huaxia Hi-Tech will provide 1000 million yuan of sponsorship to Ke Shouliang for the performance of flying over the Yellow River. At the same time, Huaxia Hi-Tech can arrange various promotional activities before the leap, and Ke Shouliang must cooperate. Qi Qi's personal portrait rights will be given to Huaxia Hi-Tech for 3 years for print advertising for free.

In fact, there are quite a lot of restrictive clauses in this contract. At least from some aspects, Ke Shouliang sold himself to Huaxia High-Tech for half a year. Basically, as long as Huaxia High-Tech is under the banner of propaganda, he has to do whatever he is asked to do. .But Ke Shouliang himself didn't feel anything strange.What he wants to do most is to drive a flying car!As long as he can drive a speeding car, he can really let him do anything!

After signing the contract, the first thing Ke Shouliang had to do was not to start publicity, but to go back and make up a few shots of the movie "Letter to Dad" with Li Lianjie and others according to the director's request.Jia Hongjian was not idle when he went to make up shots.He called Ni Runfeng and outsourced the 1000 million sponsorship fee to Changhong for 500 million.Ni Runfeng was quite surprised by the outsourcing of 500 million. For them, it is the best way for them to promote the name of cvd nationwide. Such an eye-catching campaign is naturally the best way!You must know that there are too many advertisements now. In Lingnan Province, how many companies are advertising their own advertisements in order to promote vcd!

"How is Mr. Ni's chips doing?" After signing the contract, Jia Hongjian came to Ni Guangnan and Wang Jizhi's Mi Technology to see the development status. "It's basically ok. After all, foreign countries have already developed the standards. We only need to develop the corresponding hardware according to the standards set by the other party." As he said, Mr. Wang Jizhi gave Jia Hongjian a piece of about four centimeters in length and width, which looked a bit like a CPU. chip. "This is the sample we developed. If we develop it in the laboratory, there is basically no waste product. So if we estimate the production line, the waste rate can also be within the acceptable range of 30%. And we want to make it easier for domestic factories. So try to put The chip is a bit bigger, although it is not as small as the foreign advanced technology, but it can still be used..."

Before signing the contract, Jia Hongjian just made a phone call to ask how the progress was going. I didn't expect that these two old men still have this kind of design, and they can consider various technological issues for the production line ()!At this time, I only heard Mr. Ni Runfeng say, "Mr. Jia has one more thing. The super error correction function that you asked us to study now has a little clue. The simplest method we have researched is to strengthen the laser head. In this way, small stains or small scratches can be ignored to a certain extent, and the compressed data can be recorded on the inner side of the CD disk. However, if this is the case, directly changing the power of the ordinary laser head will easily cause the service life of the laser head to decrease, and even can be restored. Caused some problems with picking discs..."

Hearing this, Jia Hongjian was really taken aback?I haven't heard of these problems in those DVD players in history that claim to have super error correction capabilities! "Old man, tell me carefully." He said hastily. "That's right. This time we chose several companies' products, such as the CD7 laser head of Philips in the Netherlands. They claim that the service life is 5 hours, but after we tested it, the actual service life is estimated to be 1 hours. I didn't expect that such an internationally renowned company would actually falsely report data..."

After making some complaints about Philips, Mr. Ni Guangnan continued, "But if you want to increase the power of the laser head in order to strengthen the error correction capability, then the laser head that can actually be used for 1 hours can only be used for three or four hours in the end. 4 hours is calculated based on the time each user spends watching 4 hours a day, that is, watching two blockbuster movies. In fact, 3 hours can make the laser head of the DVD player work normally for [-] years at most before it burns out. And so The result of increasing the power of the laser head after doing it is that the compatibility with new discs may not be very good, that is to say, old discs can come out, but new discs may not come out after being put in..."

"Therefore, our two old men suggested that this method can be used to strengthen error correction for the initial products. If Mr. Jia is not particularly anxious to develop this special error correction ability, then we have other methods..." Mr. Wang Jizhi said at this time said suddenly. "Is there any other way?" Jia Hongjian hurriedly asked after hearing this, "That is to use a special algorithm to correct errors in the two stages of compressing and extracting the disc. For example, when compressing the previous disc, the data may be [123456789 】If a bit is lost in the middle, it is easy to make a mistake. After all, the fetch end is not intelligent and does not know whether this code is arranged in ascending order, so there is no way to correct the error. But if on the one hand, the The data is stretched and divided into different positions on the disc, so that the data of the entire movie is completely disrupted and arranged on the disc. If there is still an arrangement method with error correction ability like a password, then the port can be easily calculated by the built-in decryption key. The missing information came out..."

说到了这里擅长编程的王继志老爷子也发现好像有点不容易懂就干脆换了一个深入浅出的办法来解释“比如就像是在九宫格里我们有一种方法可以让填进去的9个数不管是横向看还是竖向看甚至是对角线的斜线看加起来的和都相等这本身就是一种加密模式()。所以如果要纠错的话我们也可以用这种模式比如说假设横竖斜加起来应该等于15然后最中间的数本来应该是5但是现在因为5这里被划了个口子大家看不出来这里到底应该是几普通的影碟机此时就不出来了但是我们内置算法的话就可以通过计算算出来中间的缺口应该是5！这样一来补进去这个数据的话那么理论盘片一定比例的数据哪怕遭受到了彻底的损坏我们也可以复原播放出来完整的电影！”

Whoops I rub!At this time, Jia Hongjian really admired Mr. Wang Jizhi as a technical nerd!He was a little curious about how the old man's brain had grown so much that he could come up with such a great technique!In this way, as long as there are movie discs based on this disc pressing technology, Huaxia Hi-Tech's cvd can really reach the point in historical advertisements that can still be drilled even with an electric drill!And this is actually done with digital encryption technology!God!That kind of data encryption technology that sounds like anti-theft can actually be used for super error correction for theft?

"Mr. Wang, how did you two come up with this idea? Oh my god..." Jia Hongjian really couldn't believe it. "Hehe, it's not the credit of the two of us. Didn't we still have the task of compiling a military security system in Project 863? The military sent a few experts in cryptography and deciphering to help with the internals of the system. Various encryption algorithms. Then one day after work, the old man and we put down the work at hand and started talking about how to repair the damaged information. Then we thought that cryptographers should understand these! After all, many times they have to decipher others from scratch. Isn’t the content of the encrypted communication? As soon as we asked people, they told us some simple ways to stay away.
