MTL - The Science Fiction World of Xueba-Chapter 440 To the deep city
Pang Xuelin didn't have many excited expressions on his face. In his opinion, it was just what he meant.
Because of Pang Xuelin's calmness, the excitement of the crowd lasted for a while, and Liu Fat and Mu Qingqing's emotions soon calmed down.
Mu Donglai looked at Pang Xuelin with emotion, and did not know how this kid's heart grows. Such a technology that can be called a cross-generation technology has succeeded, and it can still maintain such a calmness.
Qi Aimin didn't notice Pang Xuelin's expression. He looked at the picture on the TV and thoughtfully said, "Xiao Pang, the compression technology you use here is not just ordinary MPEG technology?"
Pang Xuelin looked at Qi Aimin with a surprise, and smiled, "Professor Qi, can you see it?"
Qi Aimin said: "According to normal calculations, even with ordinary MPEG compression, the clarity of a VCD is at most about 250 lines, which is only equivalent to the level of an ordinary video recorder. At present, the clarity of small-screen TVs for home use is at its limit. "
Pang Xuelin laughed and said, "Professor Qi, you're right, I used the second-generation MPEG algorithm."
"Second Generation MPEG Algorithm?"
Qi Aimin froze slightly.
Pang Xuelin said, "This is a new type of data compression algorithm that I re-developed based on the first-generation MPEG algorithm. It can not only store more data information on the disc, but also improve the clarity of the video signal output. Facts In the past, this technology is no longer the traditional VCD technology. I call it CVD, China Digital Disc! "
VCD is the abbreviation of VIDEOCOMPACTDISK, which means video disc; CVD is the abbreviation of English CHINAVIDEODISK, which means Chinese own digital disc.
This has happened in the real world.
After VCD and CVD, there are SVCD and DVD.
SVCD is the abbreviation of English SUPERVIDEOCOMPACTDISK, referred to as SVCD, which means Super VCD.
DVD is short for DIGITALVIDEODISK, which means digital video disc.
The four have different standards.
VCD uses the MPEG-1 decoding technology standard, with a resolution of about 250 lines, which is only equivalent to the level of an ordinary video recorder.
CVD adopts the second-generation digital audio and video compression technology standard MPEG-2. If the 2 / 3D1 format is used, the definition of the picture can reach 350 lines. This definition has reached the limit of the definition of small-screen televisions for home use.
SVCD uses the same standard as CVD, with a resolution of 350 lines, but some technical details are different.
DVD also uses the MPEG-2 technical standard, but due to the improvement of the disc material, the definition has reached 500 lines.
Secondly, from the perspective of audio effects, DVD can provide 2 stereo channels and a 5 + 1 Dolby AC-3 surround sound channel, which can provide high-quality surround sound.
VCD is a stereo output. When singing karaoke, the two channels can store two signals of original vocal and pure sound.
The CVD audio signal is recorded with independent 4 channels, and its sound can have 4 independent channels or 2 stereo channels.
SVCD can also provide 2 stereo and 4 mono.
In addition, DVD, SVCD, CVD also added subtitles in multiple languages.
From the perspective of performance, CVD and SVCD are not much different, except that CVD focuses on entertainment functions, while SVCD focuses on education functions.
Therefore, in a sense, Pang Xuelin has mastered the world's top video and audio compression technology.
This is also Pang Xuelin in order to avoid patent disputes with Wan Yan just in case.
After all, video decoding chips based on the first-generation MPEG technology are still in the hands of Sun Yansheng's C-CUBE.
Later, even though Wan Yan closed down, Sun Yansheng's C-CUBE company still relied on this technology in the industry.
However, with the addition of Pang Xuelin, the future development of C-CUBE may 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 a video decoding chip developed by Pang Xuelin.
The second core technology is a 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 has mastered the second-generation MPEG video decoding chip, he can basically grasp the lifeblood of VCD technology development.
If we hold the whole VCD patent in our own hands, in the future Pang Xuelin will have no fear of competition in the domestic market.
The only regret is that as the definition increases, the amount of data that can be carried on the disc also increases.
Therefore, such a CD can only store up to 45 minutes of video.
But it doesn't matter, after all, even an ordinary VCD can only store up to 74 minutes of video.
A movie usually requires two discs to carry it.
As for TV series, that's even more okay.
Forty-five minutes of a TV series, just enough to burn a CD.
That night, in order to celebrate the successful development of CVD technology, Liu Fatzi specially booked a private room at a star hotel near his house. In addition to Pang Xuelin and Mu Donglai, his father and daughter, Qi Aimin and his family were also invited .
After three rounds of drinking, Liu Fatzi drunk Pang Xuelin drunkly and said, "Brother Pang, you are really my lord, not only ... not only saved me once, but also ... gave me such a rich road, tomorrow ... tomorrow Let's go and register the company. I have prepared a million funds, and I will wait ... I will wait to fight with you! "
Pang Xuelin couldn't help crying and laughing, saying, "Okay, old Liu, tomorrow we will go to register the company!"
After all, he calmed the restless Liu Fat.
On the other side, Mu Donglai and Qi Aimin also got into trouble.
The two were high school classmates, and went to the countryside to join the team. After the resumption of the college entrance examination, they were the first group of college students after the reform and opening up.
I have experienced a lot of things in this life, and I have suffered a lot. When I talk about the past, I feel emotional.
The banquet was not over until nine in the evening.
Pang Xuelin helped Liu fat man, Mu Qingqing helped his father to return home, and finally settled the two, and the two men were relieved.
Pang Xuelin said to Mu Qingqing: "Qing Qing, you should go back to bed earlier."
"Huh!" Mu Qingqing nodded, her eyes crooked into two crescent moon smiles, "Big brother, you are really handsome today."
Talking, she didn't wait for Pang Xuelin to react, bouncing back to her room.
Pang Xuelin looked at the girl's back and smiled and shook her head.
Naturally, the registered company will not be as anxious as Liu Fatzi said, but it is actually possible to register a patent.
Next, Pang Xuelin spent two days, writing six patent applications in Chinese and English, one of which directly applied for CVD related patents, including the invention of the whole machine, the MPEG2 algorithm patent, and the related patents for the video decoding chip.
As for the international patent, Pang Xuelin decided to give Liu Fatty to Xiangjiang for operation.
Fatty Liu is familiar on the other side of Xiangjiang, and can find it by finding the right law firm.
"Lao Liu, I'll leave the patent application to you, and there's one more thing you have to catch now."
"What is it? Brother Pang, you say."
Get along with this time, Liu Fatzi has long sincerely convinced Pang Xuelin.
Up to now, almost everything he has done is presumptuous.
Pang Xuelin smiled and said, "Video resources."
"Video resource?"
Fatty Liu froze slightly and said, "Brother Pang, you mean, we can go to the major audio and video publishers to buy the copyright of related film and television dramas?"
Pang Xuelin smiled and shook his head, saying: "You don't need to buy copyright, you can start piracy directly!"
Fat Liu couldn't help but be taken aback.
Pang Xuelin said: "Although CVD has already come out, resources are a big problem. If you look for an audiovisual publishing house to buy copyright, you can't get back a copy without a piece of forty or fifty. Then, when can the market do it? Therefore, if people want to pay for our products, we must have enough video and image resources and the price must be cheap enough. Only in this way can we quickly open 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 has invested heavily in purchasing copyrights of film and television dramas from major audiovisual publishers.
This was also an important reason for Wan Yan's rapid failure.
Copyright has pushed up the cost price of a large VCD, causing Wanyan to face competition from many copycat manufacturers, not being the opponents of small manufacturers at all, and quickly losing the battle in this emerging market. Become a victim of the VCD market.
On the contrary, another small cottage factory, Aiduo, started with 800,000 funds, and later spent a lot of money on CCTV. In 1996, it won the advertising standard five seconds after the CCTV weather forecast for 82 million yuan. The price of 100 million yuan became the "Bid King" of CCTV's advertising in 1998, and quickly grew into a leading company in the VCD field.
With the rapid popularization of VCD in China, the piracy industry chain has also risen.
This situation continued until the beginning of 2000, and the optical disk piracy industry gradually declined with the popularity of the computer Internet.
At the same time, the online piracy industry has also begun to rise.
Until 2020, piracy is still rampant in China.
Games, TV series, movies, and even all, have become tools of profit for piracy groups.
Fatty Liu nodded thoughtfully and said, "Okay, then I'll find someone to arrange now."
Pang Xuelin shook his head: "Old Liu, we can't end the pirated work in person. When our CVD is ready for sale, you can find someone to do this through your own contacts. The piracy industry is too profitable, as long as you increase Guide, there are people who are willing to join, what you have to do now is to prioritize the classic sources of Xiangjiang and Hollywood! "
Fatty Liu [sweet potato fo] sighed and said, "I see."
Next, Pang Xuelin stayed in Yangcheng for another three days. After submitting an application for a CVD-related patent, he followed Liu and his father and his daughter to drive to Shencheng.
At about four or five kilometers from the Second Line Pass, the minibus driven by Liu Fatzi stopped at an intersection.
After waiting for more than ten minutes, a young man, about twenty years old, with a plate inch, came over on a tricycle.
"Liu, sorry, I have kept you waiting. Who is going to pass today?"
Young men road.
Liu Fatzi pointed to Pang Xuelin and said, "Lao Chen, it is this Pang brother who is going to pass today. Just call him Brother Lin. After passing the pass, I will wait for you in the old place!"
"Rest assured, Brother Liu, I promise to send you all in a complete way!"
Then, Liu Fatzi turned his head and said to Pang Xuelin, "Brother Pang, then Professor Mu and I will pass them first. We will see you in the pass."
Pang Xuelin smiled and nodded, "You go!"
In fact, if Liu Fatzi is kind, this second-line pass covered with barbed wire and high-voltage lines is nothing to Pang Xuelin.
He could jump in a secluded corner at night, and no one could catch him.
However, since Liu Fat had arranged for a person to cope, Pang couldn't brush off the good intentions of the fat.
After Liu Fatzi left, the young man named Chen laughed and said, "Lin brother, my name is Chen, you can call me Xiao Chen. It's only four o'clock in the afternoon. If we cross the border, we have to wait at least after twelve in the evening. My second wife The home is nearby, let's go to rest for a while and go out at night. "
"it is good."
Pang Xuelin nodded.
Then, he took Chen Cheng's tricycle and followed Chen Cheng to a village near the second line.
Obviously, Chen Cheng didn't bring anyone over for the first time, and his aunt and aunt didn't ask any questions.
Instead, he prepared delicious meals and room breaks for Pang Xuelin, and everything was well organized.
Waiting until twelve in the evening, Chen Cheng knocked on the door of Pang Xuelin's room.
He held a flashlight in his hand and said, "Big brother, come with me."
The two left the village one after the other and walked along the path between the villages for nearly an hour before they came to a barbed wire near the second line.
The barbed wire here was cut out by a small mouth, just enough to go in and out alone.
Chen Cheng said, "Lin Brother, this is a new conversation that was opened a while ago, many people do n’t know yet. Generally, it only accepts individual customers, and the security is much higher than those who follow the brigade. UU reading www.uukanshu. com "
Pang Xuelin smiled and nodded, but did not speak.
Following Chen Cheng's entry through the breach of the barbed wire, the two walked along the path for more than an hour before arriving near a crossing.
Fat Liu's van has been waiting for a long time.
"Brother Pang, finally come in, get in the car."
Pang Xuelin got into the front passenger seat, Liu Fatzi rolled down the window, and lost a packet of soft Chinese to Chen Chengdao: "Xiao Chen, you have worked hard this time."
"Where is it! Fat brother, remember to find me in the future."
"Relax, you won't forget your kid."
The car quickly started and drove along the road towards the center of the deep city.
Liu Fatzi's home was located in the Luohu District of Shenzhen City, which was later the old city of Shenzhen.
