Cutting-edge disruptive technologies in the big data age

In the Zhangchuncheng, located in the Zhongguancun pioneering building, the new mobile phone. On the screen of the mobile phone, pedestrians on the road come and come, and the poplar swaying in the wind. "This is a real-time view of the HD camera at our company's doorstep and can be viewed on the phone anytime." ”


Zhang is the founder of Beijing Qian Long Teda Technology Development Co., Ltd. What he said is installed on the High-definition camera decoder, using the company's first in China to develop and research and development of successful lossless ultra-low compression image, video technology.


just over the past one months, with this decoder and the image compression technology behind it, the company has won two consecutive tens of thousands of large orders. This technology has broken the foreign compression technology monopoly in the field of PDF and TIF graphics and image, as well as the technology monopoly in H264 and MPEG4 video compression. At present, the technology has been put forward to form relevant archival industry standards based on the field evaluation of the National Archives Bureau.


image can be enlarged to reduce


"It's time to buy a hard drive." "While tidying up his own photographic work, Mr. Song, a photographer, watched as he had just bought a 500G (equivalent to 512000M) hard drive with only hundreds of m of usable capacity, exclaiming. His SLR camera, each in a lossless mode press the next shutter, it will give the hard drive to increase the storage burden of about 10M.


In addition to individual users, by a large number of data pressure is too big enterprises, government departments. "The server is Dead", and tune a content out of the card for half a day. "An Information business seminar, the chief of a police Department of Public Security Bureau complained," Every car on the highway is a click, every accident processing and each car files are data, data storage growth is much faster than the hardware expansion. ”


a 10M photo, the reporter with the computer with the Microsoft Picture Manager image processing software compressed to 0.2M or so, the compressed image after amplification, the original color, clarity are greatly reduced, many details are blurred to almost impossible to identify.


is there a technology that allows high-definition images to be less occupied while maintaining HD quality?


"This video 921M," Zhangchuncheng pointed to a video file demo, "You see, after our unique algorithm to change the file to the new format, it becomes 27M." "Double-click Compression before 921M, 27M after compression of two video, with the Storm audio and video player at the same time playing the two videos, the screen to the maximum, with the naked eye can not see the slightest picture of the difference in the definition of two."


"Don't worry, not only can compress, but also can turn it back to see." "Delete 921M original file, the compressed 27M video files after decompression, a 921M of the original file appeared again." The compression process for HD images is also the same as video.


when take out to enlarge, at leisure to reduce, Zhang as magically as the free compression of images and video files, like fiddling with "Ruyi golden" general.


independent research and development algorithm "flattening" mass data


Open a landscape photo, Zhangchuncheng began to reveal their own "Ruyi golden" is how to cultivate.


"A point seen by the naked eye is actually made up of many pixels." "Zhangchuncheng explains that each pixel in a picture is tightly aligned like a Rimini, and if you compress directly, squeeze in a tiny fraction of the" air "and the excess position.


however, as in the national Day square in the color of the square, there is a large area of the image, the pixels are "wearing" the same color value of the "coat." If you only record the color value of one point and its coordinates in the image, in the image rendering will not affect the perception, but the bloated large square "condensed" into a small team, storage space plummeted. This is the secret that the image storage size can be scaled freely.


2005, after studying in Japan, Zhangchuncheng began to work in Hitachi, China, and engaged in the analysis of satellite and aerial images. Travel in Japan to take some photos to parents to share, but due to the domestic network speed is limited, a 200M compression package, to the domestic but to spend a half a day of time.


looked at at that time international and domestic image compression software, can not lose the naked eye to see the effect of the situation of the image "smaller."


several times and domestic relatives and friends to transfer photos, file experience accumulated together, Zhangchuncheng suddenly a bright, "oneself also be proficient in graphic image algorithm, is not should develop such a technology?" ”


watched the technology around the "Daniel" have set foot on the road to entrepreneurship, 30-year-old Zhangchuncheng also can't restrain. "There is a good technology, return to entrepreneurship can accompany parents, but also realize the value of life, how good!" ”


with 500,000 yuan savings, Zhangchuncheng quit at that time in Japan a monthly income of nearly 600,000 yen of high-paying jobs. "Immersed in research two or three-month algorithm, will certainly be able to develop!" ”


The original self-confidence and heroic soaring, but by the years pulled into a hard marathon: August 2008 in Beijing returned to study abroad personnel Haidian Pioneering park, August 2009, Zhang into a full year of the development of the company to do a research, just received the first single business.


10,000 cameras can save hundreds of millions of hard drive fees


"If you want to store 10,000 high-definition camera image storage 180 days, need 90,000 2T size hard drive, and if we use our technology, we will be able to shoot the HD image real-time compression decoding, save 81,000 hard drives, that is, billions of hard disk costs." "Heard Zhang Report, Jiangsu, Guizhou and other provinces and cities, transportation, planning and other departments have become Zhang customers."


billion, this is only 10,000 HD cameras to save the cost of hard drive. Zhangchuncheng Introduction, a general scale of prefecture-level cities, about 100 streets, each street has 50 junctions, each intersection has 16-way camera, for example, a full need for 80,000 high-definition cameras.


In addition to the high definition image used in municipal departments, with the rise of large data and cloud computing, the explosive growth of data has become an unavoidable shackle in the development of Internet and mobile Internet. Zhang into this can "crush" and at any time "restore" massive data "unique skills", it is inevitable to receive attention.


Beijing Haidian District, Zhongguancun leadership one by one to the Guizhou-long Teda research, Zhang into the company's image compression technology is also known as Zhongguancun Management Committee and other government departments defined as "Frontier and Subversive Project", "Strategic Reserve Project", "major investment projects" and so on. Closely followed, industry matching, equity financing, venture capital also sniff the frontier technology "flavor" with potential "money" to find a way.


"We are working with CAS, the government authorities to declare and write the relevant new standards, for 3 to 5 years to form the industry or national standards." The company also set a 5-year planning and listing timetable. "Zhangchuncheng said. At the beginning of this year, the company has just received a large contract of 20 million yuan sales, founded just 5 years, the company's annual turnover of billion; next month, the company will also be in the eighth session of Beijing International Cultural and Creative Industry Expo released two video decoding new products, and existing monitoring equipment to achieve seamless integration.
