Since 1979 I have been in the tide of the times

Chapter 350 What is VCD II
"This kind of thing is now made in China. I bought one two months ago and it cost more than 4000, which is much cheaper than Xiaoyu's." Ou Xiaoyang said.

"Where did you buy it?" Wang Weidong asked.

"In Xidan." Ou Xiaoyang replied.

"Whoever of you two drives, take me there now, I want to buy one too!" Wang Weidong said.

"Why are you in such a hurry? When I go back today, I will buy one in Xidan and give it to you." Ou Xiaoyang said.

"No, take me there now!" Wang Weidong said.

Ou Xiaoyang and Song Yu looked at each other.

"I know the exact place, let me drive you there." Ou Xiaoyang said.

He and Wang Weidong went out and got into the car and went straight to Xidan.

Ou Xiaoyang took Wang Weidong to the counter where the electric appliances were sold, pointed to the Wanyan brand VCD and said, "This is it! Although it is much cheaper than the 3 LD player Song Yu bought, it costs 500 yuan. It's not cheap either!"

"Comrade, can you show me that Wanyan VCD?" Wang Weidong said to the salesperson.

The salesperson pressed the switch without answering and put a DVD on the tray. The VCD tray shrank, and a picture of a girl in a swimsuit appeared on the TV connected to the VCD, and singing sounded at the same time.

"Summer, summer passed quietly, leaving a little secret..."

Wang Weidong looked at the subtitles on the TV and even more so at the beauty in swimsuit who was walking around by the pool and posing.

"I have compared it, and the effect is not as good as the one Song Yu bought at home, and the clarity of the VCD is almost the same as the original VCR at home." Ou Xiaoyang said from the side.

"Comrade, I want to buy four of these DVD players." Wang Weidong said.

Hearing Wang Weidong's arrogance, the salesman shook his head in embarrassment: "The price of this kind of thing is very high, and few people buy it, so we buy very little, and now there are only two left."

"I want both! Xiaoyang, you wait here, I'll go out to get the money." Wang Weidong said.

After going out for 1 minutes, Wang Weidong came back with [-] yuan.

The salesperson issued an invoice, and Wang Weidong went to the cash register to pay the money and took the invoice in exchange for two VCDs.

Holding two VCDs and Ou Xiaoyang walked out of the mall.

"It's useless without a video disc. Xiaoyu's disc is too big to fit in. There are very few discs suitable for this kind of machine. Tomorrow, I will go to Zhongguancun to help you buy a few." Ou Xiaoyang said.

"Okay, but more importantly, I want to find an expert to dismantle this machine and study it carefully. There are many university research institutes here in the capital, and you and Xiaoyu will go out tomorrow to find one or two experts in this field to study. This machine." Wang Weidong said.

Only then did Ou Xiaoyang fully understand Wang Weidong's intention of selling these two machines.

"Weidong, don't you want to produce this thing?" Ou Xiaoyang asked.

"I'm just going to do this thing, as before, I will test the water by myself first, and then you will follow." Wang Weidong said.

"But now some people have started production, we are one step behind them." Ou Xiaoyang said.

"The first to produce does not necessarily have an advantage. We are not the first to start production of computer learning machines, let alone electronic tubes. So many electronic tube factories in China have stopped production, so we started to enter the market. As long as we produce good quality , and it’s cheap, it’s sure to make money!” Wang Weidong said.

When the two returned to Song Yu's home, Wang Weidong told Song Yu again what he had just said to Ou Xiaoyang.

"It's too easy to find an expert in the capital. I'll do it when I get back!" Song Yu said.

For this matter, Wang Weidong decided to stay in the capital for a few more days.

He did what he said, and Song Yu came to Wang Weidong only one day later.

The two drove straight to the Polytechnic University in the HD area with a VCD.

On the way, Wang Weidong asked Song Yu to stop. He wanted to bring some gifts to the professor's house.

"Buying cigarettes and alcohol is too vulgar. You are better at this than me. What do you think is better to buy?" Wang Weidong asked Song Yu.

Song Yu also shook his head, and he rarely interacted with senior intellectuals.

"Since he studies science and engineering, he must know how to use a computer. Let's drive directly to Zhongguancun and buy one or two computer accessories for him," Wang Weidong said.

Song Yu drove past the entrance of the University of Science and Technology and went straight to Zhongguancun.

Computers are very high-end, but the places where computers are sold in Beijing are like rural fairs.

Instead of going into the small counters in the building, Wang Weidong found a specialty store outside and bought a 1000m hard drive for more than 320 yuan.

Bypassing the main building of the university, Song Yu parked the car outside the residential area of ​​the family members of the University of Science and Technology according to the address, and then took Wang Weidong to walk according to the building number.

Professor Qi's family, Song Yu, also came here for the first time. He was a secretary who called his father the day before yesterday, and now he is the leader of the ministry who focuses on science and technology.

Not long after, the leader called Song Yu back and gave him the address, and told Song Yu on the phone that he had already communicated with Professor Qi, and they could come directly to the door according to the address.

Walking into the third floor of unit three, Song Yu knocked on the door on the left.

The door was opened by a middle-aged woman in her fifties.

"Deputy Minister Qiao asked us to come, because of technical problems, we want to visit Professor Qi." Song Yu said.

"Come in, Minister Qiao called yesterday, our old Qi has been waiting at home since this morning." The woman replied.

Two people walked into the room, and a middle-aged man in his fifties wearing glasses looked at them with a smile.

In fact, as far as his own personality is concerned, Professor Qi prefers to be quiet and doesn't like to be disturbed, but after all, he is the person introduced by the vice minister, so he must give this face.

Wang Weidong put the VCD and boxed hard disk on the table, and said with a smile: "Professor Qi, I'm sorry to bother you because of the New Year's Eve. We brought a machine that can play DVD images. I would like to invite you Let's take a look at the structure inside, and then help us explain it."

"After Minister Qiao called yesterday, I started looking for materials to prepare in advance. You two sit down, and I will show you my CD player." Professor Qi said.

In the living room there is a CD combo with two speakers.

Professor Qi pressed the switch, and the tray stretched out, and he put a CD on the tray.The tray was retracted, and the symphony played from the two speakers.

Professor Qi opened the VCD box, plugged the terminal wire into the VCD, and plugged the other end into the back of the speaker, and then turned on the VCD power supply.

He took the disc out of the CD player, flipped the switch and put the disc back into the vcd.

The VCD started to work, and the sound of the symphony came out from the speaker of the stereo immediately.

"See? In fact, the working principle of the CD player and the VCD player is the same, but there is an extra video decoding chip in the VCD player." Professor Qi said.

He took out a screwdriver to open the cover of the vcd, pointed to a small chip on the circuit board and said, "It should be this, this is the 32-bit chip for video decoding."

He unplugged the plug on the speaker, reconnected it to the back of the TV, and then put the CD of the beauty in swimsuit that Wang Weidong brought into the VCD.

Professor Qi pointed to the beautiful woman with bare arms and thighs on TV and asked, "Look carefully, what do you see?"

Both Wang Weidong and Song Yu wanted to say that they saw a beautiful woman, but both of them knew that Professor Qi must not be asking this question, and they would definitely make a fool of themselves if they answered that way.

So both of them were silent.

"Clarity! Look carefully at the clarity! The clarity of Vcd discs is actually not as high as that of cable TV. No wonder, the bit rate of the disc is too low. The resolution is only 352x288, and playing music is okay. I'm a bit out of control." Professor Qi said.

"Professor Qi, you know that now China has a large number of people and it's enough to manage it. It doesn't pursue high quality. I came here to ask you, is there any difficulty in producing this product?" Wang Weidong asked.

"Of course there is no difficulty in producing the casing and circuit board, but the decoding chip must not be produced in China. The laser head cannot be produced in China now. Didn't I just say that the principle of VCD is the same as that of the original CD player. Now there are mainly two manufacturers of CD players in the world, one is Philips and the other is Sony. These two companies should also be able to produce VCDs. If you want to produce VCDs, you must import them from one of these two companies. Movement." Professor Qi replied.

　The bit rate of VCD is 1.5mbps, and DVD can reach 10mbps, so the definition is much higher than that of VCD.
