"Small storage" to play "Big Data"

In March 2011, Department, the National Development and Reform Commission and other 15 central departments and Beijing jointly issued the "on Zhongguancun (000931, shares) national independent Innovation Demonstration area of the construction of talent Special zone", Zhongguancun speed up the construction of the first Chinese characteristics of the talent zone.

Zhongguancun is the most intensive area of intellectual and human resources in science and education in China, with nearly 41 colleges and universities represented by http://www.aliyun.com/zixun/aggregation/34205.html "> Peking University and Tsinghua University", with the Chinese Academy of Sciences, China Academy of Engineering is represented by the National (city) Research Institute 206, University Science and Technology Park 26, overseas students pioneering park 34.

With more than 15,000 entrepreneurs, the company has more than 6,000 founders, and is the most-established area for returned overseas students.

Zhang's mobile phone has a "God map": the size of less than 1M aerial map, magnified once, appeared in the mountains, and then magnified once, the river between the mountains, continue to enlarge, and then appeared in the river beside the dotted tents ... Touch screen of the mobile phone so that his two fingers more than 10 strokes, and finally presented in front of the tent of the woman right foot on the clear visible cloth shoes.

He told reporters that the original size of nearly 800M of "God map" can be turned into a picture of hundreds of k stored in the phone, and magnified so many times the image is not affected, thanks to lossless compression technology.

From ZCC (lossless compression retrievable color document technology) to ZCV (lossless compression Video coding technology), the founder of Beijing Qian Long Teda Technology Development Co., Ltd. used a new algorithm to compress the original image and video greatly, breaking the foreign technology monopoly in the field of graphic image and video compression.

"Previously required tens of thousands of-byte description of the file, with our technology only need dozens of bytes can be described clearly, the file is naturally" reduced. When the image is compressed to the original 1% or even 1 per thousand, it solves the problem of transmission, management and utilization. "Zhangchuncheng is using his own" shrink "to play the" Big Data "era.

At Kyoto University in Japan, the diligent Zhangchuncheng did not spend much time enjoying the picturesque scenery of the city, and he was traveling all day in the laboratory and the library. After graduating from his doctorate, he found a job as a researcher at Hitachi, Japan, but his gaze was focused on the emerging markets in China, and eventually he gave up Hitachi's steady work and returned to business with "This bucket of gold" earned in promises in Japan.

At that time, I felt that the domestic economy was developing rapidly and there were many opportunities, so I decided to come back and try. A return to the village of Zhongguancun Entrepreneurial Park, where the environment is very good, we all have a common language, what the problem we can learn from each other, what experience we can share, communication on the barrier. ”

However, cavity entrepreneurial enthusiasm into the reality of the encounter is not a small blow. The company was founded in the early days, did not receive any business, the company in 0 profit status, recruited employees see the company's old not to take a single land continued to leave the company. Zhangchuncheng said: "Our technology, although very competitive, but not familiar with the domestic market after returning home, a lot of relevant national policies and market user needs are not known, often hit the wall." ”

He spoke with a wry smile about his frustration at the beginning of his business. He used to run a lot of archives with his technology and products, the archives staff saw his technical demonstration after all praise, but asked whether there is the purchase will, the other party repeatedly waved said there is no funds; Some archives officials said that although the technology is very interesting, but the museum has a system, If the new system, docking and compatibility is a big problem, but also reluctantly expressed reluctance to adopt.

"That's it. We did take a lot of detours in this market. Zhang to see the company no improvement, he thought of giving up. But look at the people who are still standing by and firmly support their employees, he decided to gamble again.

Through his tireless efforts with several technicians, the company has independently developed a leading domestic and foreign advanced lossless high compression can be retrieved color document technology and lossless high compression of the technology can be retrieved, the technical breakthrough can be scanned the project drawings files to the original file of 1 per thousand, also let the company in the most difficult time received a project.

"This project is to do a design institute of the file system, technical demonstrations when the other side gave me a 184M drawings, and finally we put it down to more than 180 k, the customer is very surprised." Then they put forward a series of requirements, we also constantly modify the technical program, has been to customer satisfaction. ”

This time the receipt of a single experience, let Zhang into a hope. Later, after a friend introduced, the company received the first "big project" at the end of 2009.

The next single is the Guizhou provincial traffic Police Corps. Business negotiations, Zhangchuncheng or the practice of demonstrating their own technology, "to tell the truth, at that time completely do not know what we can do for each other, until the demo is over, the other party to put forward the request."

The requirements of the management file for several decades of file compression after the establishment of a database, easy to search; the hope of handling the accident to set up a resource base after compressing the accident evidence, convenient to find at any time; the hope that the information of the vehicle and the driver will be saved by data compression, and the new server

Zhangchuncheng listened attentively to each other's ideas, began to deploy, embarked on research and development, "from recruit to training to build the assembly line, we used 3 months to form a new team, and 3 months to complete the project successfully."

However, has not yet waited for the perfect answer of Zhang to submit up, the other side has put forward the new demand: hope they put the real-time video storage problem also solves.

Zhangchuncheng suddenly realized that, compared with picture compression technology, users need video compression technology more, he immediately and the team meeting discussion, will focus on the development of video compression technology. "This technology is not done before, but since the user put forward such a demand, we must meet." "Zhang into a team of countless days and nights, and finally found the video compression technology, and eventually the user to provide the historical video data compression to the original one-tenth."

Customers again under the "war post", in the resolution of the history of video compression, based on the hope that this compression technology into the front-end camera, so you can shoot real-time, real-time compression. Zhang team to complete the task according to the requirements, not only solve the bandwidth problem, more users save a huge amount of money.

Now, this new technology has been gradually promoted throughout the country.

See the company's business flourishing, Zhangchuncheng glad that they did not give up, "every company, no matter how big your business, in such a" Big data "era is extremely small, but if our technology to help others solve the" Big data "storage problem, solve the data transmission bandwidth problem, For people to save the system resources, then our company's technology is valuable.

Zhangchuncheng said: "I dream of one day can see the compressed storage technology into everyone's life, change the concept of everyone, by giving this" big data "times to lighten up, let people really usher in an environmental protection and efficient" green data "era! ”
