readx;?ld literally translates to laser disc, which is usually called laser disc in Hong Kong, Macao and Taiwan. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It works in the same way as a CD player, recording a computer-recognizable 1 or 0 signal by ablating a dimple in a coated plastic disc. After the ablation is completed, the surface of the turntable is coated with reflective material, and when the laser diode is irradiated along the track, the unablated part is strongly reflective, which is counted as 1, and the pit part is weakly reflective, and the level signal is recorded as 0.

This is the same thing as the lowest machine code.

However, due to the low level of integrated circuit technology, although the storage format is purely digital, it is very difficult to decode digitally. So the designer came up with the ingenuity of using a digital/analog conversion circuit to restore the digital signal back to the analog signal, just like playing a TV signal.

This is actually a laser video technology that uses digital recording and analog playback, which is completely different from the later digital video. Because of the same storage method as CDs, to record an hour and a half movie, the diameter of the disc must reach 30 centimeters, and it must be used on both sides before it can be used. Correspondingly, to drive such a huge laser turntable, the mechanical part is also very large, and the bald head has to be read on both sides, and the structure becomes extremely complicated.

As a result, the whole body is huge and heavy, and the price is even higher. A laser video record player costs seven or eight thousand dollars, which is more than double the price of the game console sold by Taiyu.

Such an expensive DVD player, even if the video reaches more than 720 lines and 500 lines, which is much higher than the video recorder of the TV station, it is an incomparable ultra-high-definition video in this era, but even in Europe and the United States, where the income is higher, the general population cannot afford it, and the sales are very small.

However, in East Asia, where the income is lower, due to the strong karaoke atmosphere, many KTVs have bought them as karaoke players, and the sales are okay.

This DVD player produced in the base takes the route of pure digital decoding.

From a technical point of view, a digital decoding chip that reaches the quality of TV pictures, its integration level should be at least one million. It is precisely because LD cannot solve this problem that it adopts digital-to-analog conversion, using the most clumsy means to bypass it, and using analog circuits as the final decoding method.

It is precisely because this technology is so frustrating that Philips agreed to sell it to Taiyu Technology under the mediation of Motorola, allowing Taiyu to obtain the qualification to enter the laser disc player market.

But who knew that Guan Fei, with the help of the biological subbrain, forcibly decomposed a complete decoding circuit into eight parts. As a result, the digital decoding circuit was successfully designed with three-micron linewidth process technology, and all the technical patents of VCD were exclusively enjoyed, allowing it to come out ten years ahead of schedule.

It's just that this is no longer a decoding chip, but a decoding circuit board.

Without exposing the current highest chip manufacturing level in the base area, with the same level of process technology as 286, this decoder board can only reach the initial VCD level.

Its decoding rate, at the level of 352x240 TV station image quality, can reach up to 30 frames per second required by the NT standard. At such a bit rate, because it is too late to decode, there will be occasional stuttering and mosaic during playback.

If the PAL system is selected, the decoding rate of 24 frames per second will greatly reduce the stuttering and mosaic phenomenon.

Tao Xuexiang's actual perception is similar.

As a disc for the DVD player to play the demonstration, a landscape film was deliberately selected, with a large amount of vegetation, rocky soil, and a large number of grains in the picture quality hidden as much as possible, so that the viewer will not be too sensitive to it. But despite this, Tao Xuexiang can easily feel it through the naked eye, and its picture quality has reached the effect of TV broadcast at most, which is very different from LD.

She was greatly disappointed.

Although she is not a successful businessman, she has been following her husband for a long time and has a certain business acumen.

In her opinion, this DVD player can be said to have no future.

Since the invention of the video recorder in the 70s, this video recording and playback device has gradually become mainstream. Now there is a clearer LD that occupies the high-end market.

The price of a VCR is about $3,000 or 4,000, and the price of a single player that can only play but cannot record has dropped to less than 2,000.

And this DVD player is obviously the same as LD, it can only put a good laser disc, and cannot record other programs, and the picture quality is very average. In the case that the high, medium and low end are occupied, she really can't see what value this video playback device has.

"This comrade, may I ask what kind of DVD player this is, I look very similar to a laser DVD player, what is your price?" She didn't give up right away, and leaned over again and asked.

"We mean VCD player, which means CD player. Although its definition is not as high as LD, it is cheap, only 2,100 yuan for a piece, and there are rich discs, including movies, TV series, karaoke discs, variety shows, and everything you want to watch. The salesperson just saw her standing next to the CEO of the business group, and then saw her similar appearance to Pan Meifeng, what else did she not understand, in order to behave in front of her boss, she immediately introduced enthusiastically.

Of course, if she was willing to buy one, so much the better.

A VCD sells for two thousand one, and the commission of one will catch up with several others.

"Two thousand one? How much is it in Hong Kong dollars? Tao Xuexiang was a little unsure, blinked her eyes, and desperately calculated the exchange rate in her mind.

"Mom, if you count it in Hong Kong dollars, it's six thousand nine hundred and sixty." Zhou Xiaoshan helped his wife to walk over slowly, just when he heard the second half, he quoted the price of Hong Kong dollars with a smile. He has been in Hong Kong for almost two years, calculating foreign exchange rates every day, and is very familiar with the exchange rates between the renminbi and the Hong Kong dollar, the US dollar, the Japanese yen, and the British pound.

"It's only six thousand nine, so cheap!" Tao Xuexiang was startled and exclaimed.

In the case of a video recorder, it can only play a single player that cannot be recorded, and it will be close to 2,000 US dollars, which is about 12,000 Hong Kong dollars. If it is LD, the price is as high as 40,000 or 50,000 Hong Kong dollars.

What kind of VCD is this, it's only 6,009!

It's four or five thousand cheaper than the cheapest single player!

Wait a minute......

"You just said, what kind of video do you want to watch, you all have it here?" She lowered her voice and asked in a low voice like a thief.

"yes, feature films, TV series, karaoke, everything. Even the latest TV variety shows, we have them sold here, you wait......" The little girl didn't say a word, turned around and ran towards the mall, Tao Xuexiang couldn't stop shouting.

"This girl, why is she so in a hurry, I haven't said I want to buy it yet." Tao Xuexiang couldn't cry or laugh, pulled her daughter over, and asked in a low voice, "What kind of VCD are you, how can there be so many DVDs, could it be ......?"

"That's right, we're all pirates!" Pan Meifang generously admitted.

"Ahh How can this be done, if you are caught, you will have to eat a lawsuit! Tao Xuexiang was shocked.

Zhou Xiaoshan smiled and said disapprerovingly: "Mom, you put one hundred and twenty hearts!" Our own game consoles are pirated by others every day, and all the evidence and material evidence are complete, and we haven't won a few lawsuits. Besides, although it is a pirated disc, we didn't do it ourselves, and even if we wanted to catch it, we couldn't find it. ”

"What's going on?" Tao Xuexiang was still a little uneasy.

Growing up in Hong Kong, she has always known that foreign governments are mostly for their own businessmen. Sony honestly sold a video recorder, but because it sold too well, Hollywood sued the court, saying that after the customer bought the video recorder, he ripped the movie broadcast on the TV station without authorization, and violated their rights and interests. He even said that because the video recorder can be fast-forwarded, the audience does not watch the advertisement, so that the advertiser is reluctant to advertise, which is caused by the video recorder sold by Sony, and requires Sony to compensate for huge losses.

Sony negotiated privately with the other party, intending to settle out of court, saying that it was willing to buy the copyright for use in a dedicated video rental shop.

As a result, the film company said that it was okay to make video tapes and rent, but all the rental profits must go to the film company. As a result, the two sides collapsed and could only compete in court. The lawsuit has been fought from seven or six years to this year, and it is still far away for five years, and there is no end to it.

Sony contributed money and effort to this lawsuit, and spent countless energy, which dragged them out and sold video recorders plummeted.

This is still the private behavior of the user who bought it, and they are all taken to court, and the base is blatantly pirated, and the circumstances are even worse, if they are caught, the lawsuit can be said to be won or lost.

If it affects the Taiyu Group, then even these foundries will be affected, and there will be twists and turns in the business.

"Because we have handed over the piracy business to a few associations in Hong Kong. And it wasn't us who came forward, but through other people's contacts, and there were a few turns in the middle. Even if the defendant is accused of piracy, let the police catch the personal stolen goods and seize them, we will not be able to find out about them. Zhou Xiaoshan said with relief.

"But pirated discs can only be used on your DVD players......"

"That can only say that our DVD player is good, and people are willing to make VCD pirated discs, whatever we do!" Zhou Xiaoshan sneered.

As Guan Fei's little follower, his concept of good and evil was completely learned from Guan Fei.

If it is treated fairly, then we will do business well, and we will go to worship a lot of docks. But if you treat people differently, then I'm sorry, and you're not the only one who will engage in crooked ways.

Dare to do even the murder of the head and rebel, and are you afraid of piracy?

It's not that Taewoo hasn't contacted him about copyright, but the film company just wants to drive the audience into the cinema and make all the money, and he doesn't want to share it with others. As soon as the two parties made a little contact, the other party rejected the copyright authorization of VCD suppression and sold the possibility of genuine VCD.

VCD is not like a video recorder, but also with a video recording function, what is the difference between no film source and bricks?

Business is definitely going to be done, that's the first principle.

Since the right path doesn't work, then don't blame us for taking the left side of the door.

The base area secretly passed through the members of the associations with whom they had been in contact with the past, and then quietly smuggled several sets of optical disc pressing equipment to underground societies in Hong Kong, Japan, and the United States, secretly pirated thousands of pirated discs and hoarded them. When VCDs are available in these places, they will start quietly selling pirated discs to various video rental shops or other channels.

Guan Fei knows very well that don't look at LD so expensive, and finally shut down the production line, a total of 16.8 million units have been sold in 30 years, with an average annual sales of more than 500,000 units. Video recorders are even more popular, selling millions of units a year on average.

VCD does not seek to seize all of their markets, and can get a tenth of the market share, and there are hundreds of thousands of units sold every year, creating billions of profits for the base areas, which is very satisfying.

If it is upgraded to DVD in the future, then the meal tickets for the next twenty or thirty years will be guaranteed.

With such a big gold mine, whoever wants to prevent him from getting rich, he will have to rush with whom!
