Chapter 1296: Patent in hand, I own the world
In fact, most people can accept this loss. If it is not possible, they can choose a compression ratio of six times. If you are not a professional musician, it is generally difficult to hear it. The difference between MP3 with six times compression ratio and original music disc.
Six times the compression ratio, the 64M memory stick can also hold the capacity of two CDs, which is about twenty to twenty-four songs. For today's users, it is almost enough.
As the memory stick capacity continues to increase, this performance will continue to improve, and users only need to replace the memory stick to complete the expansion, which is very convenient and cost-effective.
Such a basic design architecture is undoubtedly very advanced. Compared with several world-famous professional MP3 decoding chips in the previous generation, the design of an additional basic standard instruction set is certainly more advanced, but correspondingly , and also greatly increased production costs.
However, don’t forget that although production costs have increased, the production place is in China.
What foreigners can do for twenty-eight dollars, here, it only costs ten dollars.
Even if the cost nearly doubles, it will only change from ten yuan to more than twenty yuan, which is completely affordable.
However, the resulting improvement in product performance is no longer comparable to that of any overseas company.
The human resource cost advantage of developing countries has been completely transformed into the core competitiveness of MMD1370 and DAC3533 in this way.
The music in the player is a FLAC format file with CD original sound quality, an MP3 with a six-fold compression ratio, and a WMA song with a twelve-fold compression ratio. Two small speakers the size of a child's fist are connected to the player. The result is quite good.
The design specification requires that the player be a headphone capable of pushing 120db sound pressure. This is already the top headphone at present. However, it is obvious that the performance of the digital-to-analog conversion chip designed by Huahong is very good. , Xu Wangting used it to push and pull these two small speakers, and there was no problem at all.
“This design is very good.” Zhou Zhi thinks this can be regarded as an unexpected surprise: “It seems a bit interesting to use these two small speakers as optional external amplifier devices.”
This one The consumers of future digital products will definitely be young people all over the world. Young people are open-minded and love to show off. When chatting with couples in the park, they can be accompanied by soft music playing, and the atmosphere can be instantly felt. Laman.
“But after adding this, the power supply duration will drop drastically.” Xu Wangting said.
"Are batteries expensive?" Zhou Zhi disagreed: "When we design a small speaker, can't we add a set of rechargeable batteries to it?"
"This is a way." Xu Wangting suddenly laughed: "What if In this case we would even A set of power amplifier circuits can be added to the small speaker to make it more effective and louder. "
"But the size cannot be larger than the current one, and it must even be smaller and easier to carry. .”
"So this is finalized?" Hu Changfeng asked: "This thing must be put into production as soon as possible. We can no longer suffer the loss of going to the market early in the morning and late at night."
"The appearance design is not good enough." Zhou Zhi looked at the prototype on the table and couldn't help shaking his head. He took out a plan and a design sample from his schoolbag: "This is the design we entrusted to the French Bella Design Company. Their company has long monopolized the design of electronic products. Click the big prize and we will follow this.”
The product on the table has a very simple design, like a rounded small square box. There is a small LCD screen on the upper part of the small square box, and four four-leaf clover-shaped buttons below, plus a small round button in the middle. There are a total of five buttons that can be controlled with one hand.
The remaining interface slots are hidden on the side.
Although the design is simple, it is full of high-end design sense, which is very different from the functional prototype made by Xu Wangting on the table.
"With this appearance, it is our first iconic product - the Clover Digital Walkman. The English brand is called Lucky Clover Mutil Media Player. You should have no objections, right?"
"I think it's okay." Hu Changfeng said: "English brand?" "To make up for the shortfall of the 809 project, I'm afraid we have to make money from overseas first." Zhou Zhi smiled bitterly: "To win the favor of foreigners, we can't even say this is A product from mainland China”
“Fortunately, AXA has its own channels. We can register a branch in the Cayman Islands, package the player as an OEM product of an international company, and sell it all over the world. This way we can So as not to suffer a loss in pricing.”
Hu Changfeng will design the appearance. The book and prototype model were pushed in front of Xu Wangting: "Old Xu, how long will it take to get it done?"
Xu Wangting glanced at the model and said firmly: "One week."
"One week?" Zhou Zhi was shocked: "Isn't a week too urgent?"
"I dare to issue a military order!" Xu Wangting put the things away: "Let Lao Liao introduce the rest to you, I'm going to work!"
"Hey..."
Continue The device that came out was simpler than the previous one. It looked like a square CD player.
The capacity of a CD is 700 MB. A song in lossless compression format is almost between 40 MB and 50 MB. This is why a CD can generally hold about ten songs. .
However, with the decoding chip, the lossless compression algorithm can allow one CD to hold the music of two CDs.
If you switch to lossy compressed MP3 or WMP, one CD can even hold hundreds of songs.
This is a product carefully prepared for domestic consumption. It is a digital audio source push-pull speaker and is sold as a home music playback device.
Of course, this is just a transitional experimental product. Today, the AXA Fund has purchased the Mpeg video decoding technology patent of the American Scoop Company, and the implementation of the soft decoding program has been completed at the Shu University Computer Center.
The next step is to form a new demand document and deliver it to Huahong Group to replace the decoding application layer of MMD1370, realize chipization, and produce Mpeg video decoding chips.
Then this digital disc player will now become a household appliance that appears in almost every ordinary Chinese family - VCD.
So now this device is not ready to be put on the market at all, but is planned to be launched after the MPEG decoding chip can cover its functions.
The patented technology of the previous MPEG generation decoding chip was in the hands of the American Scoop Company. Chinese companies could only import the chips from abroad and pay patent fees. In the end, they were actually the products of foreign chip manufacturers. workers.
And even so, foreign chip manufacturers did not show favor to domestic manufacturers. In just a few years, they took away a huge amount of wealth from this tens of billions market, and used MPEG second-generation chips, namely DVDs, backhand. Decoding chips have completely wiped out the domestic VCD market.
But the situation in this life is different. The current Scoop Company has no market confidence in its technology at all, and has not even thought of suitable application scenarios. Therefore, when AXA Fund gave a return After a good price, Scobo immediately sold its technology.
With the patent in hand, I own the world.
Zhou Zhi then recruited Jiang Wanmeng from Anhui Modern Television Technology Research Institute to set up a video technology research laboratory to transform VCD products.
At the same time, through the AXA Fund, it acquired the Scobo company and the Chinese-American Sun Yansheng's laboratory in the United States, appointed him as the chairman of the Scobo company, and immediately invested in the research of the MPEG second generation protocol.
