More than half a month ago Jiang Wanmeng got the support of Mr. Xu, after getting the project funds, he couldn't wait to establish the project team, now this project team is composed of several of his skilled friends, plus a few technical cattle recruited by another high salary, this project named VCD by Mr. Xu has just begun, although Jiang Wanmeng has the initial idea, but when it comes to specific design and research and development, there will always be a lot of difficulties!

The CD on the foreign market is a kind of recording and processing of the system signal, which is carried out after digitizing the analog audio signal, and the signal stored on the CD disc is a kind of digital jù stream formed by '0' and '1', that is, a song is converted into a digital signal and stored on the CD disc, and then played out in the form of an analog signal after CD decoding!

And what they want to do now is not only to process the audio signal, but also to integrate the video signal and the audio signal together and synchronize the processing, even if a movie can be stored in a disc using MPEG compression technology, how to read the signal and convert the digital signal into an analog signal is the first big problem in front of them!

Just now, Jiang Wanmeng was following these technicians under his command to discuss how to solve this problem, and when he saw Mr. Xu, who had not seen him for many days, he was a little stunned when he came in, and after rubbing his face, Jiang Wanmeng, who had raised his spirits, greeted him and said, "Mr. Xu, you are here!" ”

Xu Hongwen saw that the other party's eyes were red, and guessed that the research and development of VCD may have encountered some problems, the research and development of a new product is a process from scratch, and the difficulties in the middle are unimaginable to ordinary people, they have nothing to learn from, they need to rely on their technology and wisdom to solve one problem and difficulty after another, and this process may experience countless failures!

Xu Hongwen, who had this kind of guess, entered the door and said hello to everyone, and said with a smile: "Old Jiang, I see that your current VCD project team is strong!" ”

Jiang Wanmeng, who was having a headache, couldn't help but smile bitterly when he saw Mr. Xu's joke, but he still said politely: "This project has been carried out thanks to your strong support!" ”

Xu Hongwen replied with a smile: "I'm wearing a high hat today, so don't wear it for me anymore!" ”

Jiang Wanmeng said hello to Mr. Li behind Mr. Xu again, these days he is also familiar with Mr. Li from Xiangjiang, Jiang Wanmeng deliberately said to Mr. Li with a little complaint: "Mr. Li, I have to complain to you, Mr. Xu will not notify me when he comes!" ”

"Haha, you can't blame me for this, Mr. Xu came over this time and also caused a surprise attack on me and the director of the factory!"

After everyone talked and laughed for a few words, Xu Hongwen asked: "Old Jiang, has there been any progress in the VCD project?" ”

Jiang Wanmeng, who saw Mr. Xu's question, couldn't help but have a bitter face, and said: "Now we are doing the overall architecture design of this machine, we have now mastered the MPEG digital compression technology, we can use a laser head similar to a CD when reading these signals, but how to filter and transcode the digital signals in the disc after reading them, our project team has not figured out a clue for so long!" ”

In later generations, this kind of signal transcoding D/A or A/D scheme can be dazzling, and you may not think that this kind of video signal transcoding is high-tech if you are using a smartphone or MP4! But in this era, it is still a world of analog circuits, and most products such as TVs, radios, video recorders and other equipment are analog circuits, and the signals in the equipment are naturally analog signals!

Xu Hongwen closed his eyes and thought for a while, he thought that the chip on the transcoding module on the VCD in later generations used Philips' technology at the beginning, and Xu Hongwen said before thinking of this: "I remember that Philips seems to have a D/A conversion chip like a digital converter, you can try to contact it!" ”

Jiang Wanmeng, who heard the news, opened his mouth in surprise, but he didn't expect that the matter that had stumped him for several days was solved so lightly, although it is still not sure whether Philips has this chip, but Jiang Wanmeng knew that Mr. Xu could not be honest!

If there is no feasible plan for digital molding, the development of this VCD is just a castle in the air, Jiang Wanmeng, who saw hope, said happily: "I didn't expect Mr. Xu to help us solve a big problem as soon as he came over!" ”

After speaking, Jiang Wanmeng asked: "Where did Mr. Xu know that Philips has this remote chip!" ”

Of course, Xu Hongwen couldn't say that he was reborn, so he casually found an excuse to prevaricate the past, and after asking and listening to their ideas about the development of the VCD whole machine architecture, Xu Hongwen felt that they were in the right direction and did not point fingers, and it was the best choice to hand over these professional things to these professional people, if he let the boss worry about everything, he would not be tired to death!

After asking about the situation, Xu Hongwen did not disturb the work of the project team again, and returned to the second floor to talk with Li Xiancheng for a while, and when he heard the bell outside, he only knew that it was time to get off work at noon under Lao Li's reminder!

Xu Hongwen, who rarely came to the factory once, wanted to see how the workers lived, so he said to Li Xiancheng: "Lao Li, let's go to the canteen to eat!" ”

Seeing that the boss was going to go down to the grassroots level to experience life, Li Xiancheng was a little bitter in his mouth, and said in his heart, big boss, you don't say hello when you come, although the food in the canteen has been greatly improved compared with before, but no matter how much the big pot of rice in the factory canteen is improved, it can be delicious there, even he, a senior worker, has never been to the canteen once, and every time he arrives at the meal, he goes to the restaurant outside to solve it!

After glancing at Mr. Xu and seeing that he didn't seem to be joking, Li Xiancheng persuaded: "Mr. Xu, the food made from the big pot of rice doesn't taste very good, or let's go out to eat!" ”

Xu Hongwen, as a native of the East China Sea, whether it is in a special period or at school, he does not eat less big pot rice, naturally he knows very well what the big pot rice is like, if in other places Xu Hongwen must avoid the big pot of rice, but this is his factory, as the boss, he has the obligation to understand the life of the workers!

Xu Hongwen said with a smile: "Lao Li, I grew up eating a big pot of rice, it's okay!" ”

When I came to the canteen, the canteen was already crowded with workers, and from afar, I saw that the director of the factory was maintaining order at the various windows of the restaurant, Xu Hongwen and Li Xiancheng did not do anything special, but lined up to eat!

Xu Hongwen, the boss, is not as well-known as Li Xiancheng, from time to time workers come to call "Mr. Li", seeing that Lao Li's neck has a rhythm of breaking quickly, Xu Hongwen couldn't help but smile and said: "Lao Li, I didn't expect you to be quite popular in the factory!" ”

Pinching his sore neck, Li Xiancheng couldn't help but complain: "Don't laugh at me!" ”

Mao Jun, who had just finished eating, turned around and was about to look for a seat, when he saw that there were two big bosses standing behind the team he lined up just now, not to mention Mr. Li, who could be seen every day, Mr. Xu, who was said to be the big boss behind the factory, was also there, Mao Jun really didn't expect that they, the big man, would come to the canteen to eat a big pot of rice!

Mao Jun, who had dealt with Mr. Xu several times, hesitated for two seconds and then quickly stepped forward and shouted: "Mr. Xu, Mr. Li, you also go to the canteen to eat!" ”

Xu Hongwen saw that Mao Jun was now full of energy, which was really different from the down-and-down appearance a few days ago, and Xu Hongwen was also happy to see his acquaintance, and replied with a smile: "Mao Jun, what you said is unreasonable, the canteen allows you to eat, can't we come to eat!" ”

Mao Jun knew that Mr. Xu was joking, if he didn't know Mr. Xu's identity before, he could still make the last joke, but now this identity gap makes Mao Jun not know how to respond for a while!

Seeing that Mao Jun was unable to speak, Xu Hongwen reacted, that is, those people in the office could know his identity, how could Mao Jun, as a workshop cadre, not know, Xu Hongwen said at this time: "Mao Jun, you go find a place to sit down first, and we will talk to you later!" ”
