"This kind of thing is now domestically produced, I bought one two months ago, and it cost more than 4,000, which is much cheaper than Xiaoyu's." Ou Xiaoyang said.

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

"In Xidan." Ou Xiaoyang replied.

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

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

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

Ou Xiaoyang and Song Yu glanced at each other.

"I know the exact place, so I'll drive you there." Ou Xiaoyang said.

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

Ou Xiaoyang took Wang Weidong to the counter selling electrical appliances, pointed to the Wanyan brand VCD and said, "This is the thing!" Although it is much cheaper than the more than 30,000 LD DVD player that Song Yu bought, 4,500 yuan is really not cheap! ”

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

The salesperson didn't answer, just pressed the switch and put a video disc on the tray, the VCD tray shrank, and the picture of a girl in a swimsuit appeared on the TV connected to the VCD, and at the same time a song sounded.

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

Wang Weidong looked at the subtitles on the TV, and even looked at the beautiful woman in the swimsuit walking around the pool scratching her head.

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

"Comrade, I'd like to buy four of these DVD players." Wang Weidong said.

Hearing Wang Weidong being so arrogant, the salesman shook his head in embarrassment: "The price of this kind of thing is very high, and there are very few people who buy it, so we have very few purchases, and now there are only two left." ”

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

After going out for more than 20 minutes, Wang Weidong came back with 10,000 yuan.

The salesman issued the ticket, and Wang Weidong went to the cashier to pay the money and exchanged the ticket for two VCDs.

Walking out of the mall with two VCDs and Ou Xiaoyang in his hands.

"It's useless to have a video disc, Xiao Yu's disc is too big to fit in. There are very few discs suitable for this kind of machine now, and tomorrow I will go to Zhongguancun to help you get a few. Ou Xiaoyang said.

"Okay, but more importantly, I want to find an expert to take this machine down and study it. 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.

It was only at this time that Ou Xiaoyang fully understood Wang Weidong's intention of selling these two machines.

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

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

"But now that someone has started production, we are one step behind them." Ou Xiaoyang said.

"The first production is not necessarily advantageous, and the computer learning machine is not the first one we started to produce, let alone the tube, so many domestic tube factories have stopped production, and we have only begun to enter the market. As long as the quality of our production is good and cheap, we will definitely be able to make money! Wang Weidong said.

The two of them returned to Song Yu's house, and Wang Weidong re-said what he had just said to Ou Xiaoyang to Song Yu.

"It's so easy to find an expert in this part of 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.

Just do it, only one day later, Song Yu came to find Wang Weidong.

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

Halfway through, Wang Weidong asked Song Yu to stop, and he wanted to bring a little gift to the professor's house.

"It's too vulgar to buy tobacco and alcohol, you're better at this than me, what do you think it's better to buy a little bit?" Wang Weidong asked Song Yu.

Song Yu also shook his head, and he had very few contacts with senior intellectuals.

"Since he is studying science and engineering, then he will definitely use the computer, so we will drive directly to Zhongguancun first, and buy one or two computer accessories for him." Wang Weidong said.

Song Yu drove through the gate of the Polytechnic University and went straight to Zhongguancun.

Computers are very lofty, but the places that sell computers in the capital are like rural markets.

Wang Weidong did not walk into the small counters in the building, but found a store outside and bought a 320M hard drive for more than 1,000 yuan.

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

Professor Qi's family, Song Yu, is also here for the first time, he is a former secretary who called his father the day before yesterday, and is now the head of the ministry in charge of science and technology.

It didn't take long for the leader to call Song Yu back and give him this address, and told Song Yu on the phone that he had already communicated with Professor Qi, and they could come to the door directly according to the address.

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

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

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

"Come in, Minister Qiao called yesterday, and 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 about fifty years old with glasses looked at the two of them with a smile.

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

Wang Weidong put the VCD and boxed hard drive he was holding on the table, and said with a smile: "Professor Qi, I'm sorry, I'm still bothering you for the Chinese New Year." We've brought a machine that can play disc images, and I'd like you to take a look at the structure inside and help us explain it. ”

"After Minister Qiao called yesterday, I began to look for materials to prepare in advance. You two sit down, and I'll show you my CD stereo. Professor Qi said.

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

Professor Qi flipped the switch, the tray stretched out, and he placed a CD on the tray. The tray was retracted, and a symphony came out of the two horns.

Professor Qi opened the VCD box, plugged the terminal cable into the VCD, plugged the other end behind the speaker, and then turned on the VCD power.

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

The VCD started working, and the sound of the symphony came out of the speakers again.

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

He took out a screwdriver to open the lid 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 swimsuit beauty disc brought by Wang Weidong into the VCD.

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

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

So both of them were silent.

"Clarity! Look closely at the clarity! The definition of VCD disc playback is actually not as high as that of cable TV. It's no wonder that the bitrate of the disc is too low. The clarity is only 352x288, and it's okay to play music, but it's a bit overwhelming if you play videos. Professor Qi said.

"Professor Qi, you know that now Chinese people are full of quantity, and they do not pursue any high quality. I'm here to ask you, is it difficult to produce this thing? Wang Weidong asked.

"Of course, there is no difficulty in producing chassis and circuit boards, but decoding chips must not be produced in China. Laser heads cannot be produced in China now. Didn't I just say that VCD is the same as the original CD record player, and now there are two main manufacturers in the world that produce CD record player movements, one is Philips and the other is Sony. These two companies should be able to produce VCD movements. If you want to produce VCD, you have to import the movement from one of these two companies. Professor Qi replied.

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