Coquettish Rebirth

Chapter [-] Crazy Idea

A general vcd actually only has a resolution of about 240 lines, that is, a resolution of about 320x240, which is similar to the current general TV resolution.The resolution of Huaxia Hi-Tech cvd is different. Although cvd is also compatible with the resolution of vcd, it also adopts the resolution of dvd. In this way, the disc and the machine can actually support a resolution of about 576x480. At this time That's pretty good already!Even if you don't use 480p resolution, but use a second-class 480x360 resolution, it will be much clearer than the current vcd on the market, and it is much higher than the limit resolution of the current TV set on the market! <——The display of the yin pole she ray electron gun picture tube, the resolution of the computer monitor is much higher than that of the TV.It turned out that the computer monitor used a completely different scanning mode than the TV.The TV adopts the oldest mode called interlaced scanning, that is, when the TV station transmits the signal, the first transmission is the half picture of the odd-numbered lines 1,3,5,7, 2468, [-], [-], etc. in the TV. , and then the signal transmitted for the second time is a signal of even-numbered lines such as [-], so that by using the residual effect of the human eye, it can make people feel that what they see is a complete picture in a short period of time.

But the result of this is that the flickering degree of the TV screen is much stronger than that of the computer, so the eyes will be tired after watching it for a long time-the frequency of electricity consumption in our country is 50hz.The signal sent by the TV is also 50hz. After being divided into odd and even, the total is 25 frames per second.However, the 25-frame picture has to go through 50 flashes, which of course makes people feel quite flashy.

What kind of scanning method does the computer monitor use?That's progressive scan!That is to say, scan quickly from the top to the bottom, so that one frame can be scanned at a time.The flickering of the picture is smaller, of course, it is more advanced.But what is the only bad thing about this scanning mode, that is when scanning in this way, because of a characteristic of the electron gun itself, that is, when the electrons are deflected under the control of the magnetic field, electric field, etc., the angle of the electron flow hits the screen The bright spots can only appear when there is no continuous electron impact, and there will be no bright spots.Therefore, when the idea of ​​progressive scanning is scanned from the top to the bottom, the picture on the upper half of the screen is actually a bit darker, which makes the human eye feel strange, as if the lower half of the screen is particularly bright. And when facing the camera and other things, such a flicker will become the kind of black stripes that move up and down!

But in these years.The advancement of technology has led people to discover a new method to improve this ill, that is double refresh rate!For example, when a short video is played on a computer, it is obviously 30 frames per second, that is, a total of 1 frames per second, but the screen will be scanned at a speed of 2012 frames per minute, that is, one picture is displayed twice. Second-rate.In this way, the phenomenon of uneven brightness and darkness seen by the human eye can be compensated.But why is it obvious that progressive scanning is more advanced, but why do TV stations still use interlaced scanning?Because this kind of thing is not what the TV station wants to change. If the TV station is changed, not only the TV station needs to return the equipment from the inside to the outside, but also the viewers have to replace all their TVs!Otherwise, the progressive scan signal and the old interlaced TV will definitely not be able to watch - think about it, in [-], tens of thousands of people in developed countries like the UK are still watching black and white TV!If the model is changed, maybe people bought a TV with a lot of money a few years ago, but the machine is not broken but they can’t watch it. Don’t the audience think that the TV station is forcing people to change the TV?Isn't this letting the audience point at the back of the TV station's leader and scold her?

But at this time, Jia Hongjian wanted to raise this issue in front of Ni Runfeng. "What? Progressive scan TV?" Of course Ni Runfeng knows the terminology in this industry, but this kind of thing has always been just a so-called theory. Progressive scan things are usually used on computer monitors. No one really Get it on TV! "But Mr. Jia, this kind of cost is too high! No one uses progressive scanning in the TV. The main reason for this is that many photographic equipment use the interlaced mode when recording, that is, they have already recorded interlaced. Scan the separate mode! This is called interlaced video. This kind of signal cannot be played directly in a progressive scanning machine, but it needs to be calculated by adding a special digital anti-interlacing chip. The cost will increase a lot. !"

"I know!" Jia Hongjian was obviously not surprised at all!He knows the digital flat-panel TV in the future in history, how to get it when broadcasting the signal of the TV station?Isn't this all relying on the built-in chip?The easiest way - the first picture transmitted is "upper", and the next picture is "outer", then wait for the time of one picture, when the last and last pictures are upside down, merge the two Get up, isn't it a complete picture, and then play the reality to come out!Then when the next game comes, it will play the picture of the previous frame repeatedly, and when the next game comes, it will play the complete second frame again!In this way, an effect similar to "progressive scanning" can be achieved, and it is also compatible with interlaced scanning signals!The only disadvantage is that it needs a chip?

"How much does it cost to add such a chip? 100 yuan? Even when it is provided in large quantities, the price of a chip is 100 yuan, but when this concept and TV of this quality come out, you can't buy 200 or 300 more? Why does Changhong continue to develop new products? Shouldn’t we use technology and new features to increase the added value of our products? With added value, we can sell more expensively, at least at the beginning, so that we can make money There are more people than in price wars! Otherwise, if you fight price wars all day long, you will kill one thousand enemies and lose eight hundred. Isn't this against yourself?" Yes, in Jia Hongjian's view, this Changhong's biggest The advantages and the biggest disadvantages are price wars in time.Because of the price war, I became the leader in the market, but also because of the price war, I can't actually make much money from TV, let alone relying on this to make a technology with my own characteristics—— ——If you make two or three mistakes in choosing the technical route, then you can only be the second and third in the market!

"Okay...then let Huaxia Hi-Tech develop the chip?" Ni Runfeng felt that his Changhong really needed Huaxia Hi-Tech's support. Call a difficult actinium.But at this moment, Ni Runfeng's phone rang suddenly.He picked it up, didn't say anything for a while, and finally said: "I still need to study this matter, and I'll talk about it later..." Then he hung up the phone.

Just when Jia Hongjian was curious, Ni Runfeng said frankly, "Boss Zheng Baiwen called and wanted to continue to represent our sales, saying that as soon as they go public, they will be able to pay back, so it doesn't matter, at most it will be delayed for half a year. That's all." "Hehe, this Zheng Baiwen really can't help, and being a dealer is actually not what they should do!" Jia Hongjian shook his head, if this Zheng Baiwen was only serious about being a middleman, Then maybe Jia Hongjian would help out a little bit, but Zheng Baiwen made all kinds of false accounts and cheated all kinds of things, so Jia Hongjian really didn't want to help!

"What Zheng Baiwen did is wrong? Then what should they do?" Ni Runfeng was very curious. In his opinion, Zheng Baiwen's approach is actually very advanced, and all kinds of credit transactions are used. Can this not be advanced! "For them, the purchase price should be equal to the shipment price, or even reversed, that is, the purchase price is 100, and the shipment price is 90!" There are quite a lot of crazy ideas in Jia Hongjian's mind! "Buy 100, sell 90? This...isn't this a loss?" Ni Runfeng didn't understand.

"If you think about it, I bought a billion worth of goods from you, and then sold them for 9.9 million. On the surface, I lost 1 million, which is 1%, but I can use this to seize most retailers, and We can also use this method, which is cheaper than the ex-factory price, to sign an agreement with the retailer to pay first and then deliver goods, so that when the other party’s purchase money is on our side, we can use it to lend to financial institutions! This point You, old Ni, know that borrowing for a month is 9 points of rebate interest! How much is the 10 points rebate interest out of the 9 billion? 9000 million! So although I lost 1000 million on the surface, I actually took advantage of it. I can earn 8000 million with financial leverage! I can even play a bit bigger. It’s not impossible to lose 4000 million on the surface and actually earn 1000 million! Is there any risk in this way? At least the risk is not on me! And I can also seize a large number of channels through my cheap or even loss-making sales, and finally I control the market, and can provide the market with the cheapest goods, and even ordinary people can benefit! This is a win-win situation!" Yes , The method adopted by tlc is to buy at a fair price. This is a method that can be appreciated by Jia Hongjian, but the tricks that Jia Hongjian can come up with are obviously more crazy than tlc's!Even more extreme... At 22:30 in the day and night, Wang Kexuan and Wang Xinyu stood on the cold side of the road for more than an hour, looking for the owner of the lost money. "We are worried about the owner who has lost a huge sum of money, and hope that he can come back to look for the wallet as soon as possible. We have been waiting for more than an hour, and we have to go back to our hometown in the county with our parents to celebrate the New Year, so we have to ask Uncle Wu." Wang Kexuan rubbed his hands. Said the little hand.The two children picked up the wallet in the parking lot of Nanwan Ecological Park. After waiting for more than an hour in the wind and snow, they still couldn't see the owner.In the end, I had to find Mr. Wu Qingyong, director of the Municipal Health Supervision and Law Enforcement Bureau.
