Chapter 72： [Streaming Technology Patent]

Determined the development schedule for the first half of the year, Luo Sheng convened a development team of 150 internal employees, led by Xu Yong personally, Luo Sheng himself also entered the development sequence.

At the same time, the company is also hiring various types of engineers with high salaries.

For the next half month, Xu Yong was in charge of the development of MusicSpace, and Luo Sheng was in charge of the development of Bluestar Video, but he would not keep immersed in the development of the technology department. The main purpose is Setting up the framework is more useful for cultivating engineers' development capabilities.

The difference between Lanxing video and Aeolus video is technically different first. Aeolus video is not an online player, not streaming technology.

The so-called streaming media technology is a network transmission technology that saves the complete image and sound data on the website server after compression processing, and users can obtain information while downloading, so that it is not necessary to download the entire compressed file and then watch it.

Uh ...

"As early as the end of the last century, IT giants including Microsoft and Apple saw the potential of streaming media technology and developed their own products. The IETF began to formulate relevant Technical specifications, hoping to make the products of many manufacturers compatible with each other and jointly expand the market. "

At this moment, Luo Sheng and members of the development team began to exchange technologies while sitting in the lounge. For the members of the development team, Luo Sheng is definitely the technology **** in their minds. Not only can they expand their horizons, they can also learn Many new things can definitely kill university computer professors.

"In April 1998, the IETF's multimedia group released the first standardized streaming media communication protocol RTSP 1.0, which marked the development of streaming media technology into a standardized track. In addition to Microsoft and Adobe, other manufacturers such as Apple, PacketVideo, etc. all support the RTSP 1.0 protocol in their products. "

Speaking of which, Luo Sheng raised his legs, and said lightly, "But our Bluestar videos do not use the services of any streaming technology companies on the market today, because their technology is too poor, we develop new ones ourselves. Is a streaming media transmission protocol that is not sold externally and is only used for our own products. "

Lu Siming said: "Boss, do you mean that our streaming media technology does not support the RTSP 1.0 protocol?"

Luo Sheng nodded: "What I want to build is my own ecosystem. Bluestar Technology is a" family bucket ". It is not because of its pride and lack of money that it chose not to adopt the RTSP 1.0 protocol. There is no sufficient prediction of the rapid growth of Internet broadband and the large number of proxy servers due to the shortage of IPv4 addresses. "

"In addition, there are certain flaws in transmission reliability and ease of use. I firmly believe that the next few years will definitely be the big explosion of network video. I do n’t use RTSP 1.0 protocol, others want to do streaming video. The service provider companies aren't going to be too interested, it's just that I look far ahead of them before they respond. "

Bluestar Video's development team is currently developing a streaming media technology called "LvHTTP", which uses an instant messaging protocol embedded in the video.

The development of Internet technology has a great feature of "winner-take-all". In the application layer protocol, HTTP has the potential of winner-take-all. This is not Luo Sheng's technology. Its founder is the father of the World Wide Web www. Masterpiece by Nas Lee.

The HTTP protocol was originally designed as a web browsing application with the B / S architecture. It is simple and easy to use. Now the industry believes that the protocol is not suitable for use in applications such as streaming media that require high real-time performance, and will cause communication problems. The extra load is heavier.

However, Luo Sheng's Lv obviously overturned this point. At present, Lv has been developed. In most cases, Lv applications use HTTP as a bearer during internal testing. This can ensure that they can be used directly in most networks without complexity. Configuration and commissioning.

This is not to blame others, after all, Luo Sheng's vision has gone beyond this era for decades.

The current broadband speed is generally around 1M, but Luo knows that the IP network broadband will increase rapidly in the future, and it is a matter of recent years. If the current broadband speed is compared to a 10 cm diameter water pipe, then a few years later The diameter of the water pipe will increase by one meter or even ten meters. Under this trend, the additional communication load caused by HTTP is no longer important. On the contrary, it will show more and more obvious advantages in terms of ease of use. Became the de facto standard.

Naturally will not choose RTSP1.0 protocol.

Uh ...

In the following days, Luo Sheng led the team to continue to develop, create a unique online technology LD recompression algorithm for Bluestar Video, and apply for a patent.

LD technology can ensure that users can watch 720P HD video smoothly at a broadband speed of less than 1M. At this time in early 2004, it was definitely the world's leading streaming media playback technology.

Taking domestic as an example, the current main population of Internet users is using 512K ~ 1M broadband. With limited broadband resources, smooth viewing of high-definition videos online is what users expect and the core competitiveness of Bluestar Video.

Luo Luosheng attaches great importance to the problem of not playing online video cards, because this is also a concern of users. In a word, user experience.

Obviously, for the fluency of online video playback, it is necessary to clarify the concept of a bit rate, that is, the larger the bit rate Kbps, the larger the video file. If the bit rate is too large and the broadband speed cannot keep up, the video will freeze. And even stuck into a dog.

The highlight of 重组 LD technology's recompression algorithm is that the picture quality is the best in the industry when the bit rate is the same, and the bit rate is the lowest in the industry when the picture quality is the same.

Uh ...

底 At the end of February, Luo Sheng was busy developing here, launched in North America as planned, and the website itself is positioned as a social news site. The slogan for the launch was: voice ahead of the news, voice from the Internet.

D The Reddit born in Luo Sheng's hands, at least has a superb change from the previous Reddit, that is to change its humble pages, rough graphics, large block of text, etc., the webpage is exquisite and smooth.

The reason why the Reddit of the last generation lost the **** is also due to the funding. After all, the bandwidth cost will increase accordingly. Fortunately, Bluestar Technology is not bad, although it has not earned a penny.

Isn't this money with VC.

At the beginning of Reddit's launch, product owner Russell Simmons asked the international version of BlueSpace for pop-up advertisements to help Reddit drain, but was rejected by his boss, George Charles.

Because Luo Sheng explained to George, even warned ~ www.novelhall.com ~ If he dared to pop up a small advertisement window without his permission on the international version of BlueSpace website, he would be fired, even if he Is a small ad.

George is very happy about his current job. He completed his performance last year, raised his salary to $ 1.08 million as expected, and obtained options allocation of shares of Bluestar Technology. He exercised at the valuation price after Series B financing. The myth of Series B financing It made him realize that in the near future, Bluestar Technology Co., Ltd. could become a billionaire on its IPO.

So far, the international version of the BlueSpace website has reached 20 million users in North America. Basically, universities in the United States have been successfully captured. George Charles fully refers to the expansion model of China and successfully replicated in North America.

Now it is expanding to users outside the university. The expansion rate of BlueSpace website in North America can be said to be unmatched.

Facts have proved that the Chinese side has proved that this model can succeed, and the North American side can also succeed, and vice versa.

There is even an illusion that BlueSpace seems to be more suitable for Europe and the United States and has more potential.

With 20 million users, this is a very large amount of traffic, but it cannot be diverted, which makes Russell Simmons very depressed.

However, Bluestar Technology is very well-known at home and abroad, and its launch is also attracting much attention from the Internet community at home and abroad, as well as VCs that invest in Bluestar Technology.

At a glance, the industry and VC were stunned.

As the founder of the real-name social network and the most slippery Internet company, the features of the new product's anonymity mechanism contrast sharply with its core business.

Is this all playing with snake skin?

Uh ...
