As mentioned earlier, the Moving Picture Expert Group (FITE) is an organization jointly established by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to establish video and audio standards for optical discs, and its members are technical experts in the fields of video, audio and systems.

The MPEG-format, the standard for compressed transmission of moving images, has successfully separated the recording of sound and image from the traditional analog method, bringing the audiovisual transmission into the digital era.

The video compression and coding technology of the dynamic image compression transmission standard mainly uses the inter-frame compression coding technology with motion compensation to reduce the time redundancy, the DCT technology to reduce the spatial redundancy of the image, and the entropy coding to reduce the statistical redundancy in the information representation.

It is the combination of these technologies that greatly enhances the compression performance.

It can be said that if there is no dynamic image compression transmission standard, there will be no VCD, DVD and a series of discs, and there will be no MP3, MP4, and even video websites, short videos will not appear.

After all, the storage space occupied by the original video is too large, and if it is not compressed, the network before the 4G era will not be able to quickly transmit it to other users.

It's not a strange thing to even watch the film for two hours and download it for two days and two nights.

Or maybe this is the real experience of network users before the 56K small water pipe, and even the 2G network.

And even after the 4G era, if the video is not compressed and transmitted, the experience brought to users will still not be very good.

After all, users who are used to loading videos with zero latency can't tolerate waiting another minute or two to watch a video, or even ten seconds.

However, in reality, the Moving Picture Experts Group is not what people think, but an international academic and scientific organization composed of technical experts in various video, audio and systems fields, and has been given other meanings.

As we all know, the so-called fourth-rate enterprises sell coolies, third-rate enterprises sell products, second-rate enterprises sell brands, and first-class enterprises sell standards.

Researchers from companies such as Sony, Philips, Toshiba, Yamaha, Javis, Kodak, and their funded scientific research institutions occupy the entire Motion Picture Expert Group and have the absolute right to speak.

As it may sound, it may sound understandable that the disc itself was invented by Sony and Philips, and then Sony and Philips also released the Red Book of the CD-DA standard, which defines how to store sound data in the form of audio tracks.

The standard yellow book of CD-ROM defines the file data format and two types of file data storage MODE1 for computer data storage and MODE2 for compressed video image storage, so that CD becomes a universal storage medium, and adds debug detection code and correction code to ensure that computer data can be read completely and error-free.

Yamaha established the standard for gigabit discs, Kodak launched the Orange Book for photo discs, and Sony, Philips, Javis, and Kodak jointly developed the white paper standard for VCD discs.

It can be said that these companies have made a great contribution to the standard for the compression transmission of dynamic images and the standard for optical discs.

But the reason why these companies are so active in promoting dynamic image compression transmission standards and optical disc standards, in addition to promoting technological development, the most important thing is to seize the right to speak, to put it more bluntly, is for profit.

After all, the standards they set are tantamount to turning their company's products and technologies into a framework, and any latecomers must go within this frame and strictly follow the path they have set to buy their technology patents.

In other words, these so-called international technical expert groups set standards, but the standards include the patents of these companies.

This means that as long as you enter the industry, you must follow the standards set by these expert groups, and once you follow the standards of these expert groups, you will inevitably use the patents of these companies, and then the rest seems to be the only way to go by honestly paying money.

The most well-known and most famous "Qualcomm Tax" is in this form of grabbing money.

Qualcomm invented a large number of mobile communication technology, and these mobile communication technology has become the current mobile communication technology standards, all communication enterprises, including communication equipment manufacturing enterprises, terminal enterprises, mobile phone companies, etc., as long as they want to connect their products to the network, they must use these mobile communication technology standards, then naturally they have to pay for Qualcomm.

The patent licensing fee that each communication equipment manufacturer pays to Qualcomm is higher than its own profits.

In other words, the emergence of these expert groups has greatly expanded the barriers and even benefits that can be formed by enterprise patents.

If there is no such standard, the company will develop a similar patent on its own, and it will be bypassed.

Now, if a company wants to develop another patented technology on its own, it will be excluded from the entire standard or even the entire industry, and it will not be able to survive at all, let alone develop.

Just like mobile network communication technology, is Huawei really unable to bypass the technical barriers formed by Qualcomm?

The dynamic image compression transmission standard, because it is still in the promotion stage, has no practical application, and it can even be said that it is the only practical application to real life, that is, Xiaobawang's DVD player.

Therefore, there was no patent authorization fee, but Sony, Philips and other manufacturers also sent a patent authorization letter that expired at the end of this year.

And also pretended to absorb Qingtian into the moving image expert group and became one of the members of the expert group.

In fact, it is understandable for these companies to be done by the expert group, after all, the establishment of standards is not entirely a bad thing.

First of all, after the establishment of the standard, the vast majority of enterprises do not have to pay R & D expenses, and furthermore, it is conducive to the interconnection between enterprises and countries.

For example, if each company has its own set of standards, it is likely to be formed, and the discs needed by Xiaobawang can only be produced by Qingtian itself, because the discs produced by other companies cannot be played by Xiaobawang's DVD player, and the same Xiaobawang's CD can not be placed in the DVD player produced by other companies.

It also means that once consumers buy whose DVD player, they can only use whose house they have, once replaced, the previous disc is all reduced to waste, and consumers are firmly tied to a company, completely losing the right to choose.

This is especially true for mobile communications, if the standards are not uniform, it is very likely to change countries, and users need to change a calling card, or even a mobile phone.

But the problem is that for the sake of their own interests, these companies practice monopoly hegemony and hinder technological progress, which is a bit too bad.

Just like now, in the R&D and production process of DynaSky's DVD player, according to the actual situation, many new technologies have been produced and applied to its own DVD players and CDs.

This is supposed to be a good thing, but at this time, the moving image expert group jumped out and said that DynaSky's DVD players and discs violated the international standards they had set, and ordered DynaSky to immediately bring the production and technical standards of DVD players and discs into line with international standards.

In other words, the technology that DynaSky has worked so hard to develop has been forced by these people to use the patented technology of Sony, Philips, Toshiba, Kodak, Yamaha, and Javis on the grounds that it violates international standards.

And also hypothetically said that now there is no need for DynaSky to pay patent licensing fees, and it also avoids DynaSky's investment in scientific research and technology.

This obviously has ready-made food to say, and you have to work hard to do it yourself, it seems that no matter how you think about it, you feel that Qingtian, Fang Chen's brain is sick.

But the question is, once DynaSky really doesn't have scientific research capabilities, let alone patents that can compete with it, what will Sony, Philips and others do if they charge high patent fees to DynaSky?

Yi Fangchen thought, at that time, in addition to quitting the DVD player, it seemed that there was only one way to go, honestly bow your head and be slaughtered.

However, there is another problem, Qingtian's DVD players, and even the entire Huaxia DVD players, need to pay royalties to Sony and Philips, while Sony and Philips can license each other for free.

In this way, it does not mean that the production cost of Sony and Philips is lower than the cost of Qingtian and Huaxia DVD players, which will greatly increase the competitiveness of these foreign companies.

This is the real big trouble, the big kill!

In the previous life, around 1996, foreign companies such as Sony and Philips attacked Huaxia in a big way, and its low-end DVD player relied on its cost advantage, almost in a short time, the average price of two or three thousand Huaxia DVD players fell to about 1,000 yuan.

And in addition, the movements and laser heads, which can only be produced by foreign companies such as Sony and Philips, have not only risen sharply, but also had no price at a time, and Chinese companies could not buy goods at all.

For a time, the Huaxia DVD player enterprises that had finally developed were instantly beaten to pieces, and they could not form an army, and the original domestic DVD player market with a 100% market share was cut away by a third by foreign companies.

However, the most important thing is that because the price can only be reduced to compete, coupled with the reason that the foundation is too thin, the DVD player produced by Huaxia cannot avoid cutting corners.

Enterprises cut corners, then consumers will naturally not agree, and there will be fewer and fewer people willing to buy, but they will pursue high-priced, high-quality foreign high-end DVD players.

With fewer buyers, companies will be more inclined to cut corners, saving costs, and a vicious circle has been completely formed.

As a result, even though Huaxia enterprises still occupy two-thirds of the DVD player market, 80% of the profits generated by the entire market have been taken by foreign companies.

It can be said that Sony, Philips and other foreign companies have given Chinese enterprises a modern business war course.

Therefore, it is impossible to let Qingtian give up his own research and development technology, and he Fang Chen will not do this if his head is kicked by a donkey.

But in this way, there is a problem, the moving image expert group led by Sony and Philips did not agree, otherwise how would they send this invitation letter.

This is clearly the drunkard's intention not to drink, but to Pei Gong.

"Sony and Philips are really calculating, Akari invited us to participate in the MP3 standard setting, but in fact, whether we can be elected or not, is not still up to them to vote, and I'm sure that they will also bring up the fact that the standard they use is different from the international standard they have set, and will force DynaSky to change back. Duan Yongping said with a disdainful face.

"You can see it thoroughly. Fang Chen said with a smile.

"As far as their calculations are concerned, I'm afraid that three-year-old children can see it clearly, and Sony and Philips have just sent a message that they want to reduce the supply of our movements and laser heads, the reason is that they have also begun to produce their own brand of DVD players, so the production capacity of parts and components cannot keep up for a while. ”

Duan Yongping didn't feel like being praised, but said undeniably.

Just like a college student is praised for reciting a 99 multiplication table well, it is really hard to say whether this is a compliment or an insult.

Hearing this, Fang Chen's expression suddenly became a little subtle.

After a few breaths, he said with a smile: "Although the DVD player is not a difficult thing, if you start doing it from now on, you will definitely not be able to do it well in a year and a half. ”

What bullshit, Sony and Philips are going to produce their own brand of DVD players now, a month ago Sony and Philips didn't move at all, why did they suddenly appear now and say that they were going to produce their own.

And most importantly, he has been busy for so long that he only got the DVD player out three months ago, and the Sony and Philips projects will only be in these three months.

After all, Sony and Philips were bent on making DVDs with higher technical difficulty and better effects, which means that they knew the sales of Xiaobawang DVD players in the past three months, and they were moved, and then they planned to develop and produce DVD players.

He admits that the technology of these two companies is indeed strong, and there are many technologies and products of the two companies in the DVD player, but the basic common things and physical rules still have to be followed.

This is the development and production of a new product, not blowing up balloons, how can it be so simple.

He thinks that by the end of this year, it will be good for these two companies to get the DVD player out.

The reason why these two companies said this to Qingtian is obviously to force him to conform and make him honestly accept the international standards they have set.

Speaking of this, Fang Chen glanced at the invitation on the table, a cold glint suddenly flashed in his eyes, and he said in a terrifying tone: "But I'm afraid that in the end, Sony and Philips will find that they picked the wrong opponent, and they let themselves be defeated." ”
