The Science Fiction World of Xueba

There was not much excitement on Pang Xuelin's face. In his opinion, this was completely justified.

Because of Pang Xuelin's calmness, everyone's excitement lasted for a while, and Fatty Liu and Mu Qingqing quickly calmed down.

Mu Donglai looked at Pang Xuelin with some emotion, and didn't know how this kid's heart grew. Such a technology that can be called cross-age was successful, and he was able to remain so calm.

Qi Aimin didn't notice Pang Xuelin's expression. He looked at the picture on the TV and said thoughtfully: "Xiao Pang, the compression technology you use here is not just ordinary MPEG technology?"

Pang Xuelin looked at Qi Aimin in surprise, and said with a smile, "Professor Qi, did you see it?"

Qi Aimin said: "According to normal calculations, even after compression using ordinary MPEG, the definition of VCD is at most about 250 lines, which is only equivalent to the level of ordinary video recorders, but the definition of the TV screen in front of us is at least 350 lines. The resolution of small-screen TVs currently used in the home is at the limit."

Pang Xuelin laughed and said, "Professor Qi, you guessed right, I just used the second-generation MPEG algorithm."

"Second generation MPEG algorithm?"

Qi Aimin was slightly taken aback.

Pang Xuelin said: "This is a new type of data compression algorithm that I redeveloped on the basis of the first-generation MPEG algorithm. It not only enables the disc to store more data information, but also improves the clarity of the video signal output. In fact In fact, this technology is no longer VCD technology in the traditional sense, I call it CVD, China Digital Optical Disc!"

VCD is the abbreviation of VIDEO COMPACT DISK, which means video disc; CVD is the abbreviation of CHINA VIDEO DISK in English, which means Chinese own digital disc.

In the real world, this has happened before.

After VCD and CVD, there are SVCD and DVD.

SVCD is the abbreviation of SUPER VIDEO COMPACT DISK in English, referred to as SVCD, which means Super VCD.

DVD is the abbreviation of DIGITAL VIDEO DISK, which means digital video disc.

The standards for the implementation of the four are different.

VCD uses the MPEG-1 decoding technology standard,

The definition is about 250 lines, which is only equivalent to the level of ordinary video recorders.

CVD adopts the second-generation digital audio-visual compression technology standard MPEG-2. If the 2/3D1 format is used, the definition of the picture can reach 350 lines.

The standard adopted by SVCD and CVD is the same, and the definition has reached 350 lines, but there are differences in some technical details.

DVD also adopts the technical standard of MPEG-2, but because of the improvement of disc material, the resolution has reached 500 lines.

Secondly, from the perspective of audio effects, DVD can provide 2 stereo channels and 1 5+1 Dolby AC-3 surround sound channel, which can provide high-quality surround sound.

VCD is 1 channel stereo output, when singing karaoke, the two channels can store the original singing and pure audio signals respectively.

The audio signal of CVD is recorded with independent 4-channel, and its sound can have 4 independent channels or 2-way stereo.

SVCD can also provide 2 channels of stereo and 4 channels of mono.

In addition, DVD, SVCD, and CVD have also added functions such as subtitles in multiple languages.

In terms of performance, CVD and SVCD have little difference, but CVD focuses on entertainment functions, while SVCD focuses on educational functions.

Therefore, in a sense, Pang Xuelin currently has mastered the world's top audio-visual video compression technology.

This is also Pang Xuelin's intention to avoid patent disputes with Wan Yan just in case.

After all, the video decoding chip based on the first-generation MPEG technology is still in the hands of Sun Yansheng's C-CUBE company.

Later, even though Wanyan went bankrupt, Sun Yansheng's C-CUBE company still thrived in the industry with this technology.

But now that Pang Xuelin has joined, the future development of C-CUBE will be questioned.

After all, VCD technology itself is not a particularly high-tech technology, at best it is an idea.

There are two core technologies. The first is the video decoding chip developed by Pang Xuelin with so much effort.

The second core technology is the laser reading probe.

At present, laser reading probes are mainly in the hands of Sony and Philips. These two companies mainly exist as component suppliers and have not joined the competition in the VCD market.

Therefore, as long as Pang Xuelin masters the second-generation MPEG video decoding chip, he basically grasps the lifeblood of the development of VCD technology.

If he holds the VCD machine patent in his own hands, Pang Xuelin will not be afraid of the competition in the domestic market in the future.

The only regret is that while the definition increases, the amount of data that the disc can carry also increases.

So such a CD disc can only store up to forty-five minutes of video.

But it doesn't matter, after all, even an ordinary VCD can only store 74 minutes of video at most.

A movie generally requires two discs to carry.

As for TV shows, that's even better.

An episode of TV series lasts forty-five minutes, just enough to burn a CD.

That night, in order to celebrate the successful development of CVD technology, Fatty Liu specially reserved a private room in a star hotel near his home. Besides Pang Xuelin, Mu Donglai and his daughter, Qi Aimin and his family were also invited over. .

After drinking for three rounds, Fatty Liu pulled Pang Xuelin and said drunkenly: "Brother Pang, you are really my nobleman. Not only... not only saved me once, but also... gave me such a way to get rich, tomorrow... tomorrow Let's go and register the company. I've already prepared one million funds, and I'll wait for that time...I'll do a big fight with you!"

Pang Xuelin couldn't help being a little dumbfounded, and said: "Okay, Lao Liu, let's go and register the company tomorrow!"

It was with great difficulty that the restless Fatty Liu was calmed down.

On the other side, Mu Donglai and Qi Aimin also started arguing.

These two were classmates in high school, and they went to the countryside together to join the team. After the resumption of the college entrance examination, they were also the first batch of college students after the reform and opening up.

This most of my life has experienced many things and endured a lot of hardships. When talking about the past, I feel emotional.

The banquet was not over until nine o'clock in the evening.

Pang Xuelin helped Fatty Liu, and Mu Qingqing helped her father back home, and they were finally settled, and they were relieved.

Pang Xuelin said to Mu Qingqing: "Qingqing, you should go back to bed earlier."

"Yeah!" Mu Qingqing nodded, her crooked eyes turned into crescents, "Brother Pang, you are really handsome today."

Saying that, she skipped back to her room without waiting for Pang Xuelin's reaction.

Pang Xuelin looked at the girl's back, smiled and shook his head.

Naturally, the registration of the company will not be as anxious as Fatty Liu said, but the registration of the patent can indeed start.

Next, Pang Xuelin spent two days writing six patent applications in both Chinese and English, one of which directly applied for CVD-related patents, including the invention of the whole machine, MPEG2 algorithm patents and related patents for video decoding chips.

As for the international version of the patent, Pang Xuelin decided to hand it over to Fatty Liu to go to Xiangjiang for operation.

Fatty Liu is familiar with the road in Xiangjiang, and he can find a suitable law firm to do it.

"Old Liu, I will leave the matter of patent application to you, and there is one other thing that you have to deal with right now."

"What's the matter? Brother Pang, tell me."

After getting along during this period of time, Fatty Liu has long been convinced by Pang Xuelin.

Up to now, he has followed Pang Xuelin's lead in almost everything.

Pang Xuelin smiled and said, "Video resources."

"Video resource?"

Fatty Liu was taken aback for a moment, and said, "Brother Pang, what do you mean, we can go to major audiovisual publishing houses to buy the copyrights of related film and television dramas now?"

Pang Xuelin shook his head with a smile, and said, "You don't need to buy copyright, just start piracy!"

Fatty Liu couldn't help being taken aback.

Pang Xuelin said: "Although CVD has come out, resources are a big problem. If you buy the copyright from an audiovisual publishing house, you will not be able to pay back the cost without paying 40 to 50 yuan for a disc. If this is the case, when will the market start. Therefore, if we want people to pay for our products, we must have enough video resources and the price should be cheap enough. Only in this way can we quickly open up the market through VCD.”

Pang Xuelin is very clear that the popularity of VCD has a lot to do with piracy.

In the real world, in order to cultivate the VCD market, Wanyan Company invested huge sums of money to purchase the copyrights of film and television dramas from major audiovisual publishing houses.

This is also an important reason why Wanyan went bankrupt quickly.

The copyright has pushed up the cost price of VCD by a large margin. As a result, when Wan Yan faced the competition from many counterfeit manufacturers, she was not at all the opponent of those small manufacturers, and quickly lost in the competition in this emerging market. Became a victim of the VCD market.

On the contrary, another small copycat factory, Aiduo, started with a capital of 800,000 yuan, and later spent a lot of money on CCTV. In 1996, it won the advertising label five seconds after the CCTV weather forecast for 82 million yuan. At the end of 1997, it won 2.1 The price tag of 100 million yuan became CCTV's advertising "big king" in 1998, and it quickly grew into a leading enterprise in the VCD field.

With the rapid popularization of VCD in China, the piracy industry chain has also risen with the tide.

This state lasted until the early 2000s, when the CD piracy industry gradually declined with the popularization of the computer Internet.

At the same time, the online piracy industry has also begun to rise day by day.

Until 2020, piracy is still extremely rampant in China.

Games, TV series, movies, and even, have all become profit-making tools for piracy groups.

Fatty Liu nodded thoughtfully, and said, "Okay, then I'll find someone to arrange it now."

Pang Xuelin shook his head and said: "Old Liu, we can't end the piracy work in person. When our CVD is ready to be released, you can find someone to do it through your own contacts. The piracy industry is too profitable, as long as you pay a little Guidance, some people are willing to join, what you have to do now is to prioritize the selection of Hong Kong and Hollywood classic film sources!"

Fatty Liu [Sweet Potato fo] was stunned, and suddenly said: "I understand."

Next, Pang Xuelin stayed in Yangcheng for another three days. After submitting the application for CVD-related patents, he drove to Shencheng with Fatty Liu, Mu Donglai and his daughter.

When it was about four or five kilometers away from the Second Line Pass, the van driven by Fatty Liu stopped at an intersection.

After waiting for more than ten minutes, a young man in his twenties who kept his body size came over on a tricycle.

"Brother Liu, I'm sorry to keep you waiting, who is going to pass the test today?"

The young man said.

Fatty Liu pointed to Pang Xuelin and said, "Old Chen, this Brother Pang is going to pass the test today. You can call him Brother Lin. After passing the test, I will wait for you at the old place!"

"Don't worry, Brother Liu, I promise to send Brother Lin to you in its entirety!"

Then, Fatty Liu turned his head and said to Pang Xuelin, "Brother Pang, then Professor Mu and I will pass the pass first, and we will see you in the pass."

Pang Xuelin nodded with a smile and said, "You guys go!"

In fact, if Fatty Liu had good intentions, this second-line gate covered with barbed wire and high-voltage lines would be nothing to Pang Xuelin at all.

He can find a secluded corner to jump over at night, no one can catch him.

However, since Fatty Liu arranged for someone to meet him, Pang couldn't take advantage of Fatty's kindness.

After Fatty Liu left, the young man surnamed Chen said with a smile: "Brother Lin, my name is Chen, you can call me Xiao Chen. It's only four o'clock in the afternoon. If we pass the customs, we have to wait at least after twelve o'clock in the evening. My second uncle Home is nearby, let's go to his place to have a rest first, and then go out at night."

"good."

Pang Xuelin nodded.

Then, he got on Chen Cheng's tricycle and followed Chen Cheng to a village near Erxianguan.

Obviously, this was not the first time Chen Cheng had brought someone here, and his second uncle and aunt didn't ask any more questions.

Instead, they prepared delicious meals and rooms for Pang Xuelin to rest in, and everything was arranged in an orderly manner.

It was not until twelve o'clock in the evening that Chen Cheng knocked on the door of Pang Xuelin's room.

Holding a flashlight in his hand, he said, "Brother Pang, come with me."

The two left the village one after the other, walked for more than an hour along the path between the villages, and finally came to a barbed wire fence near the second line pass.

The barbed wire here was unexpectedly cut with a small opening, just enough for one person to enter and exit.

Chen Cheng said: "Brother Lin, this is a new opening not long ago, and many people don't know about it. Generally, only individual customers are accepted, and the safety is much higher than those who go with a large group of people."

Pang Xuelin smiled and nodded, but did not speak.

Following Chen Cheng into the barrier through the gap in the barbed wire fence, the two walked along the path for more than an hour before they came to an intersection.

Fatty Liu's van has been waiting for a long time.

"Brother Pang, you're finally here, get in the car."

Pang Xuelin sat in the passenger seat, Fatty Liu rolled down the window, threw a pack of soft China to Chen Cheng and said, "Xiao Chen, thank you for your hard work this time."

"Where is it! Fat brother, remember to find me if you have business in the future."

"Don't worry, I won't forget you kid."

The car started quickly and drove along the road towards the center of Shencheng City.

Fatty Liu's home is located in the Luohu District of Shencheng, which is later the old city of Shencheng.
