Countercurrent 1982

The next moment, Duan Yun looked at the test bench.

I saw a 10-inch LCD screen on the experimental table at this time, and beside the screen, a circuit board, transformers and other equipment were randomly connected, and a power switch was placed on the left side of the table.

"This is……"

"This is the MP4 player we are developing." Ni Guangnan said to Duan Yun.

"What? You told me this thing is an MP4 player?" Hearing what Ni Guangnan said, Duan Yun couldn't help laughing.It’s just that Duan Yun will behave like this, because the messy things in front of her make it difficult to connect to the MP4 player in her era. You know, even if it is the first MP1 player in the world, he only has one.
The size of a palm. "Now in the technical verification period, I mainly demonstrate the design principles of MP4 products with our engineers. The real development has not yet started, and I need to convey the design ideas to others first." Ni Guang
Nan explained.

"I see." Duan Yun nodded. "From the current situation, I have listed several core technologies for making MP4 players, including display screens, processors, and new software and decoding software, especially the software part, we need to redevelop." Ni Guangnan thought for a while, and then said: "Take our MP3 storage as an example, if you want to make the player as big as a palm, then the size of the hard disk can only have a storage capacity of about 1G at most to store MP3 songs. If you want to store dozens of songs, there is no problem, but if you want to use it to store files, with the data volume of the current software, it can only be played for a few minutes at most, that is, an MTV
That's all..."

"That's right, we really need to develop a brand new software." Duan Yun nodded.Just like the original MP3 research and development, the storage capacity is still the most difficult problem to solve. This is a hardware technology that requires very high processing and design of the chip. Taking the current 0.5 micron technology of Tianyin Group as an example, it is still not enough.

Not enough to make a qualified MP4 memory.

In addition to memory, display is also a technical threshold that is difficult to cross.In 2002, the display screen used by the world's first hard drive MP4 player was a 26-inch color LCD screen with 3.5 colors. At that time, this LCD screen had a very good display effect. It can be said that

The most advanced LCD screen at that time.Although Tianyin Group obtained the LCD production technology from Sharp in the early years, and also invested in research and development funds for subsequent continuous research and development, in general, it is still very difficult to achieve a breakthrough in LCD technology. It requires a lot of investment, on the other hand, the cost of the product is also very high, and the most critical point is that in the current domestic home appliance market, the market share of LCD TVs is not high, even less than 5%. , the reason is that compared with traditional analog monitors, the price of LCD TVs is very high. The minimum price of a 24-inch LCD color TV is around [-] yuan.
The price of a flat-screen color TV is only 3000 yuan.Another point is that the miniaturization of liquid crystal displays also faces many technical bottlenecks. For example, the pixels of liquid crystal color TVs are not high, but because the screen is large enough, when viewed from a farther place, the image feels still It is relatively clear, but once the LCD screen is reduced, the graininess of the LCD screen will appear very rough, and the definition will also decrease. If you want to improve the definition, it means that you must...

The pixel density has been greatly improved, but with the current technology, the desired effect cannot be achieved.

Finally, there is the issue of software. Relatively speaking, Tianyin Group's software research and development capabilities are very strong, but it also takes a lot of time.The MP4 player developed by the French company back then supported the format of Mpeg4. This encoding mode is a very advanced image compression standard. The playback effect is clear, and the file size is only 2 times that of DVD.
5%~30%, and it is precisely because of this that the name of this player is called MP4.In general, Duan Yun wants to complete the research and development of MP1 players within 2 to 4 years. The task is still very arduous. Both software and hardware require huge investment.
There is a price to be paid. "My feeling is that even if this product can be made, the cost will be very high. This is almost a small TV, and the requirements for the miniaturization of electronic components are too high." Speaking of this, Ni Guangnan

His brows frowned slightly.Compared with Duan Yun, Ni Guangnan has a better understanding of the difficulty of developing this product, because he stays in the laboratory almost every day, closely following the R&D plans of all departments. This is actually a very torturous process, because
The development process of any top new product is very long, and there is still a huge risk of failure. People with poor psychological quality are actually not suitable for this job.Although it is said that Tianyin Group is owned by Duan Yun, the failure of the project development and the loss is Duan Yun's money, but Ni Guangnan has always been a very strong person, and now the development of Tianyin Group has been closely linked to his future.
After all, he resigned from Lenovo Group before. If he did not achieve very good results in Tianyin Group, it would also damage his personal reputation. "You don't need to think about the cost for the time being. I just need you to make something for me. Whether it can be sold is another matter. At least you must first prove that the technology of this product is feasible. Tianyin set

The regiment also has the strength to make it, which is enough. " Duan Yun said.

As Duan Yun said, he just wants an MP4 prototype that conforms to his design ideas. As for the cost, Duan Yun didn't think too much about it.Because once the prototype is made, Duan Yun can directly register the related technology of this product for patent, so as to set up a very high patent barrier for future competition, so that Tianyin Group has an absolute advantage in this product.

right advantage.As for the cost issue, with the development of technology, the cost of electronic components will only get lower and lower, just like the original MP3 player, when it was first developed, the estimated cost price was as high as 15

However, after mass production, the cost quickly dropped to 8000 yuan. However, today, the price of MP3 players in the United States is only 560 US dollars, which is less than 5000 yuan if converted into RMB. "Understood, I will make the product first according to the plan we agreed on before." Ni Guangnan said.
