This fat friend , You are 4K Even 8K HD live broadcast raised your eyes , I can go back 1080p Do you ？

Especially since this year , What Winter Olympics , Launch of the space station experimental module , The sharpness is really high one by one . All major platforms also wish to 4K Write it directly on your face as a standard .

Watching the 1080p It's almost a thing of the past , But I don't know if you have thought about such a problem ：

The definition of video is getting higher and higher , But the bandwidth of watching videos has not increased much ？

This involves such a technical keyword ——

Audio and video codec technology .

in fact , In response 5G In this era, videos mention too many problems , And achieve higher definition 、 More immersive 、 Interactive experience with lower delay , The audio and video industry has been focusing on H.266、AV1 Wait for the standard encoder to update and iterate .

More Than This , Today's audio and video coding and decoding technology , Also took advantage of the deep learning of the east wind , Explore an update faster 、 Innovate a new path of faster development .

that , Is deep learning likely to bring disruptive changes to the audio and video industry in the future ？ With the increasing maturity of artificial intelligence technology , How will the future of audio and video technology develop ？

If you're interested in this question , Now? , Have a chance to open the little red book , Listen to the top experts in the domestic audio and video field directly ~

Technology masters share online

It's just 7 month 27 On Tuesday night 19:00, Xiaohongshu technical team will invite The first prize winner of the national technological invention 、 Wang Shanshe, associate researcher of School of computer science, Peking University Participate in 【REDtech coming 】 Technology live broadcast , Just “ The past of video coding 、 Present and future ” Share the theme .

2020 year , By virtue of super Key technologies of polymorphic primitive encoding and decoding of HD video Won the first prize of the National Technological Invention Award . He is currently working in the National Engineering Laboratory of digital video codec technology , Presided over “ oriented 8K Efficient coding standard and codec for UHD video applications ” And other national key R & D plans .

Besides , Wang Shanshe studied under Gaowen, an academician of the Chinese Academy of Engineering . Academician Gao Wen devoted himself to the research of key technologies of video coding and decoding 19 year , Took the lead in formulating the with independent intellectual property rights AVS Series standard . The National Engineering Laboratory of digital video coding and decoding technology he is responsible for has led China's digital video industry to achieve a huge leap from a blank core technology to an international leader , It has transported a large number of technical backbones for the development of the industry .

in addition , Chen Jing, the head of xiaohongshu's audio and video architecture, will also take xiaohongshu's practice as an example , Introduce the landing challenges of audio and video technology in the industrial application field 、 Innovative practice and development exploration .

By 2021 year 10 month , The number of monthly active users of xiaohongshu exceeds 2 Billion , Has a wide range of 、 real 、 High real-time user scenarios , Massive audio and video notes , And rich and complex user viewing behavior data .

Chen Jing once served as 51Talk Chief audio and video scientist 、Google Chrome Media Video team Engineer 、Mindspeed Senior manager of video department DSP The engineer 、 Video team engineer of Huawei central R & D department , Successively published works 《 Deep understanding of video codec technology 》 And translation works 《 Computer vision algorithms : be based on OpenCV Computer application development 》.

Wang Shanshe and Chen Jing will also focus on the development dilemma of audio and video technology 、 Carry out in-depth conversation on topics such as the possibility of combining in-depth learning with audio and video technology ：

• Exploration of new audio and video technologies , What are the differences between industry and academia ？

• Whether deep learning will subvert video codec ？

• Where is the next outlet of audio and video ？

• Who will define the new generation of codec Standards ？

• Fluency 、 Whether massive concurrency and other pain points will usher in a technical inflection point ？

• What video compression algorithm improvements have the pursuit of Ultra HD brought ？

besides , at present , The little red book REDstar The recruitment plan for top technical talents has been officially launched .REDstar Project period , Xiaohongshu will hold several live broadcasts of cutting-edge technologies .

“REDstar〞 It is xiaohongshu's exclusive talent recruitment plan for top technical talents in Colleges and universities around the world , Committed to REDstar Provide competitive salary and welfare 、 The exclusive training program with great sincerity and the practice channel of daring to promote young people .

except 7 month 27 Outside the audio and video topics of the evening ,8 month 5 Japan 19：00, Little red book will also invite Zhang Yue, associate professor of West Lake University And Pangliang, assistant researcher of the network data science and Technology Laboratory of the Institute of computing, Chinese Academy of Sciences bring “ The frontier and practice of natural language recognition ”.

What about? , Do you have an appointment for live broadcast ？
