At this moment, the technology R&D team of Zhifu is also in class.

It was Lin Yaodong who taught them a lesson.

What Lin Yaodong taught is also what he is learning.

When this class was different from Zhifu's class, the lecturers were very excited, and the listeners were shocked.

Here's what's going on

The encoding algorithm and decoding algorithm are very efficient, a little scary, and the compression ratio is to this extent, and the image quality can still be like this

And streaming solutions are even more unheard of.

On the server side, the video content is divided into fragments, and each fragment is also divided into different encoding forms according to e, resolution, bitrate, etc. On the user's player side, you can freely switch the playback time and resolution, and switch seamlessly in the background.

The technical team of Zhifu only thinks that the technology is awesome.

But in Lin Yaodong's understanding, this is to establish a new standard

The standard of audio and video encoding and decoding, and the standard of streaming media protocol

When Lin Yaodong asked Gu Song, Gu Song said yes, it is the most advanced standard, a by-product of the research and development of decoding chips.

My good boy.

"When the decoding chip comes out, I will take advantage of the current trend of 3 popularity and the demand for network transmission of video content, so that this set of standards will become a new international standard."

Lin Yaodong went back and studied it, and now the H264 standard is in the final discussion and has not been officially released, and the set of standards taken out by the Flint Research Institute has many obvious advantages.

Since the algorithm is more advanced, and the requirements for hardware performance are reduced through optimization, and the versatility is strong, if the Chinese organization forces propose it to ITU, what reason does the world have to refuse?

In Lin Yaodong's view, this is naturally the case.

But it's not that simple.

ITU is the oldest international organization among the United Nations agencies and is responsible for global ICT matters, including the allocation and management of radio frequencies, satellite orbit resources, and the development of global telecommunication standards.

Audio and video coding standards are only a small part of it.

But it is this small piece of content that affects the entire global video industry, including the development of the online media industry.

ITU's audio and video coding standards are basically updated every ten years. And 03 is the day when the new generation of standards is officially announced.

Each generation of standards, from the proposal to its acceptance, to its global recommendation as an important standard, needs to be adopted by a majority of all Member States and participating companies.

There are countless games of interest in this.

Lin Yaodong didn't know that because of this thing, Ni Guangbei was already running around.

In the building of the Ministry of Information Industry, Ni Guangbei put this set of technical solutions on the desk of Director Ding of the Department of Science and Technology.

"You said, the research institute where you are now a consultant has come up with the most advanced core standard scheme for audio and video coding" Director Ding looked at the plan in front of him, he couldn't understand it, but Academician Ni, don't make fun of this

Ni Guangbei said seriously, "Yes, I and several academicians have already been examined. Director, this is a critical time for ITU to consider new standards, and we need to get in touch as soon as possible to promote this set of standards to become international standards."

Director Ding's face was unbearable, "I'll organize experts to study and see how this matter can be promoted."

He made a phone call, and the secretary came over and took the materials and left. Director Ding looked at Ni Guangbei and said with a smile, "Academician Ni, you have made great achievements one after another, this is the effect of devoting yourself to research after you came out of association."

Ni Guangbei shook his head and sighed, "It has nothing to do with me, it's Professor Liu Hanhao who is presiding." As a consultant, apart from helping him introduce the scientific research team at the beginning, I didn't have much guidance later. ”

Director Ding asked curiously, "That young man really invested 100 million yuan in it."

"Director Ding is very well-informed," Ni Guangbei smiled, "I started to study audio and video decoding chips after the USB flash drive control chip came out last time, and it hasn't come out yet." In July, another 50 million funds were added, plus 50 million at the time of establishment, which is indeed 100 million. ”

Director Ding sighed, "I'm really willing to invest." I've heard that now I have an income."

Ni Guangbei nodded: "It is said that the research institute is behind it, and it is to rely on patent fees to make up for a little funding." There aren't many of them yet, and there are plenty of alternatives. ”

"Academician Ni, tell me, what else is the research plan in the future" Director Ding's eyes flashed.

"I only know that I also want to do CU in the end, and as for which topics to study along the way, I have to ask Gu Song. Ni Guangbei thought about it and sighed with emotion, "He has a USB flash drive, an audio and video, what he is going to do next, Professor Liu doesn't know." However, he has mentioned cameras before, perhaps related to this. ”

Director Ding was a little excited, "Is it OS or D?"

Ni Guangbei shook his head, "I don't think it's like, in the field of image sensors, there is too little technology accumulation now." The control chip and audio and video chip are mainly optimized in terms of algorithms. But whether it is OS or D, it involves the manufacturing process of components, two different things. On the contrary, it is the image processor, which may be something in this regard. ”

Director Ding sighed, "It's really difficult to make some breakthroughs in core chips." ”

"Isn't Loongson coming out, is the date of the official announcement set?"

Director Ding looked excited, smiled and said, "It's set, September 28th." ”

"I hope that this chip will bring a great excitement to the domestic scientific research community and industry," Ni Guangbei said, his voice somewhat envious.

At that time, he ambitiously established "Lianhaiwei", but in the end he lost to the "trade, industry and technology" route and was swept away. Today, Lenovo has a huge trade performance, and industrial production has indeed been promoted, but only the core technology has never been available.

Ni Guangbei also can't see the day when Lenovo has the core technology of computers.

If they could support themselves at the beginning, from 94 to now, 8 years, maybe the first domestic CU would have come out a long time ago.

Now, regret is regret, and it is also a relief to see Loongson come out.

It's just that it would be best if the project had its own involvement.

Thinking of this, he couldn't help but think of Gu Song.

Perhaps, I want to have a good chat with him to see if I can also exert my residual heat.

"Director Ding, you are so concerned about the matter of coding standards. Ni Guangbei got up and said goodbye, "I'll also go to the research institute to see if the decoding chip can catch up with the time when it will be released with Loongson, and then there will be a dual-core jump." ”

Coming out of the Ministry of Information Industry, Ni Guangbei went straight to the Digital China Building.

As soon as he arrived downstairs, Ni Guangbei was waiting for the elevator and heard Gu Song's voice, "Old Ni, what a coincidence"

Ni Guangbei saw Gu Song coming over, and he was also very surprised, "Is there any new progress in the absence of classes today?"

Gu Song shook his head and said with a smile: "I arranged for a few people to come over to learn video encoding and streaming media technology, and after a few days of learning, it is estimated that it will be about the same." Let's take a look at the progress. ”

He saw that the end was smooth, and when Poplar also tried to speak, he came from that side. In the future, it is to let Luo Xi return to the center to contact and organize interested students to record classes.

It is also a good part-time job for some students. Of course, not everyone can earn this money, and it is still necessary to write handouts in advance according to the accumulated experience, and there must be a certain typhoon.

The two chatted and went upstairs to the door of the research institute, and saw Liu Hanhao, who was tired and excited.

Ni Guangbei was startled, "Xiao Liu, how long have you not slept here?"
