As for the other core technology, the movement technology is the reader that reads the VCD disc, whose movement Wan Yan used at that time, Lei Weidong didn't know, and he didn't check it, but it is certain that it is not his own movement, because Wan Yan does not have the technology to produce the movement by himself.

At that time, there were only two movement manufacturers in China that could produce and read the second-generation decoder board of C-Cube, namely Sony and Philips.

At that time, it was said that because Sony did not pay attention to this fast, the production volume could not keep up, and the domestic movement was basically monopolized by Philips.

Do you know how much the movement sold for at that time?

It is said that the production cost of a Philips movement is less than 20 US dollars, and the sales cost is 70 US dollars, which is also several times the profit.

It is said that just these two components, the two major manufacturers have earned tens of billions of profits in China within a few years. This may be the source of the legendary Philips and other companies in the VCD market that have been rumored to be in the VCD market.

But Philips and C-Cube make this kind of money, and those VCD manufacturers in China can't do anything at all, or you don't produce VCD, if you do, you have to buy his things. It can be said that the technological monopoly is the most terrible, and you are powerless to resist it.

Of course, a rather complex control system needs to be added between the decoder board and the movement in order to be perfectly connected to play the digital disc, which involves the development of many accessories and system control components.

It is estimated that the development of Wanyan at that time was mainly this piece, but this piece was nothing to those giants at all!

With their scientific and technological content, even if Wan Yan applied for a patent, it would be easy to bypass.

At that time, in order to monopolize the market, C-Cube and Philips cooperated to provide technology directly to VCD manufacturers who took goods from their own manufacturers, so that those manufacturers could use the control systems provided by the two companies to directly produce VCD machines.

The windfall profits of Philips and C-Cube did not come to an end until a third company joined in.

Seeing that Philips and C-Cube are making a lot of money, the responsible company is certainly not reconciled.

The first to challenge was ST, because there was no technical force in China to develop the decoder board, so ST went abroad to find it.

In Silicon Valley, ST invested $1 million in the development of VCD decoder boards for ESS in the United States.

Finally, in 1997, ESS withdrew from the mature second-generation decoding chip to break the technology monopoly of C-Cube.

At the same time, Japanese manufacturers produced a large number of movements in China, which made the price of the decoder board and the price of the movement drop sharply, ending the windfall profits of the two major companies.

However, at this time, the major domestic VCD manufacturers have started a price war.

The VCD ended the era of profiteering and entered the era of low profits, and a VCD was reduced from a few thousand yuan at the beginning to a few hundred yuan a piece.

In the end, no one in the entire VCD market can make a lot of money, and they can only make some hard money.

After VCD, in 97, the domestic DVD player industry complacently engaged in a "super VCD" standard, wanting to resist the impact of DVD.

However, the compression method of MEPG-2 digital video is owned by others, the decoding chip is owned by others, and the CD-reading and writing mechanism is owned by others.

Foreign giants can easily jam the necks of domestic manufacturers, and in the face of the impact of DVD, "Super VCD" quickly eliminated DVD.

In the DVD era, domestic manufacturers did not have any intellectual property rights to speak of, so that in the era of low profits, overseas film machine manufacturing giants only relied on patent fees to stuck.

Although there is no need to pay fees for domestic sales, once exported, a large amount of patent fees need to be paid, which makes domestic DVD manufacturers miserable, and finally even sues foreign giants for patent monopoly.

These are the pains of not having technology, but it is not possible to apply for one or two patents to replace, because many patents can be bypassed, which is by no means difficult for those international giants.

In the era of smart phones, there are too many patent wars between several major mobile phone manufacturers, and large American companies like Apple that first came up with smart phones have not been able to plug the patent gap, allowing Samsung and other manufacturers to catch up in smart phones, not to mention domestic companies to set up patent barriers.

It can be said that there are no shortcuts to the industrial base.

These are far away, let's talk about what will happen if Wan Yan applied for a patent at that time, and whether there will be another scene.

First of all, in 95 years, when VCD sales began to boom, when the rise of DVD player manufacturers such as Aiduo, Jinzheng, and Xinke, could Wan Yan use patents to block these manufacturers from the technology?

Definitely not, not to mention the domestic environment at that time, even the mainland market in the 21st century is estimated to be unlikely.

Because intellectual property rights are not valued at all in many people's minds, patents are often used in China, and besides, Aiduo, Jinzheng, and Xinke are star enterprises in various places, large taxpayers, and enterprises protected by the local government, and in the eyes of those government departments, they don't care about Wanyan's patents!

All they care about is whether they can collect taxes, develop the economy, and promote employment, and they can only do these things, and they will definitely give a green light to their own enterprises, even if Wan Yan uses patents to crack down on these enterprises, it will not work, and everyone will not recognize your patents, what can you do.

As for whether Wan Yan, a company that produces components such as Philips and C-Cube, can control it, let alone whether it is possible to use patents to sanction them.

Besides, these two are only component manufacturers, and they can't be involved in the VCD patent at all, even if they are like those VCD manufacturers to provide the control system between the decoder board and the movement, they can also develop it themselves, completely bypassing Wanyan's patent barriers.

Because this kind of technical trifle is so simple for the two big tech giants.

Then there is the foreign market, VCD DVD player is equivalent to cassette recorder in the audio-visual level, but there is no transcription function of cassette recorder, and it is difficult to eliminate video recorder under the same technical conditions.

The most important point is that the cassette video recorder industry has developed in developed countries for nearly 30 years, it can be said that 90% of the families in these developed countries such as the United States and Japan have one or several video recorders, and it is impossible for VCD DVD players with no technical advantages to eliminate video recorders in developed countries in Europe and the United States.
