With the rapid development of 5G, cloud computing and artificial intelligence, the ubiquitous video is coming along with the trend, and the content expression forms and information interaction modes between people, people and things, and people and society are changing rapidly.

Ali Cloud video cloud has been focusing on and promoting such a new era of new content and interaction. In this era, the digital intelligence of audio and video created by video cloud is constantly extending new technologies, creating new opportunities, and constantly reconstructing many industries and creating new species.

Invited to LiveVideoStack, Aliyun Video Cloud will explore and discuss new technologies, new opportunities, new products and new applications of video cloud with numerous video cloud industry partners from April 16 to April 17.

Technology creates new businesses

Deep Discussion on “Technology Business Strategy”

As the storm of the epidemic swept the world, many companies sought to grow in the midst of difficulties, while many companies stood on the crest of the wave in the midst of prosperity. The great era of video is accelerating, and new multimedia technologies, new products and new applications are constantly bursting out. During this time, the video cloud bursts with powerful potential energy everywhere.

The value of video cloud lies in the creation of lower cost, lower threshold, stronger experience, and universal technology benefits. It has reconstructed many industries on the basis of accelerating the upgrade of digital intelligence. The most obvious is to reshape education, conference, e-commerce, mutual entertainment, medical care, finance and other industries and innovate their growth models.

In the future, digitalized video cloud will continue to empower more industries, create new scenes, new fields and new species, lead the second growth curve of the industry, and eventually develop into the underlying ability common to the whole industry.

The best balance between cost and experience

“Optimization and Thinking of Ali Video cloud Narrowband HD”

With the completion of the new generation of video codec standards represented by VVC, EVC, AVS3 and AV1, the software and hardware optimization of the existing codec standards for diversified businesses has gradually become an industrial hot spot. On the other hand, the use of AI technology to improve the efficiency of traditional video coding compression is booming along the two technological paths of human viewing and machine task.

In this field, Ali Cloud put forward the technical concept of “narrowband HD” as early as 2015, and officially launched the narrowband HD technology brand and productized it in 2016. Since it was put forward, the whole industry began to gradually adopt this concept, forming an industry consensus and constantly evolving today.

“Narrowband HD” represents a video service concept that combines cost and experience. It is a video coding technology based on the optimal subjective perception of human eyes. Up to now, The “narrowband HD” of Ali Cloud video cloud has introduced AI for details/color adaptive repair and enhancement. Relying on ali Cloud’s unique technical algorithm, it has broken through the upper limit of the capacity of the video encoder and provided the “best subjective experience” viewing experience while saving bit rate.

  • In the final analysis, narrowband HD is a compression problem. With the development of deep learning, video processing and video generation assisted compression have become the focus of research in academia and industry. What is our view in this direction? What is the ultimate goal of narrowband HD?
  • In order to achieve this ultimate goal, what are the short-term and long-term ideas of Ali Cloud video cloud for narrowband HD technology?
  • Why is the only way to evaluate narrowband is subjective?
  • Based on this idea, we in the short-term progress and the layout of the future and thinking.

Cloud side integration and collaboration

“Evolution of RTC Service Architecture Based on Edge Cloud Native”

Large-scale computations are performed locally, and the requirements on terminal performance are more stringent. Based on 5 g, cloud native, containers, SD – WAN, such as the development of technology, we can quickly to transmit more information to the cloud for processing, and using edge of distributed computing technology, the characteristics of low latency, intelligent terminal + + the clouds on the edge of the new architectural pattern will also provide strong motivation for more new media services.

With the application of Internet video technology in many industries, especially the development of ultra-low latency scenarios, RTC cloud services are gradually developing from cloud architecture to cloud native and edge cloud. Ali Cloud video cloud is based on the cloud-edge-end integration collaboration, which moves the terminal computing power up and the cloud computing power down, forming computing power fusion at the edge, thus promoting the evolution of RTC service architecture.

Evolution of RTC Service Architecture Based on Edge Cloud Native

Share content:

  • Edge cloud native = Cloud architecture + cloud native + edge cloud
  • Cloud architecture: The resilience of infrastructure to provide services quickly and support customer business development
  • Cloud native: elastic ability of RTC service, multi-service mixed running ability, multi-cloud ability
  • Edge cloud: Complex network architecture, higher quality for specific scenarios, privatized deployment
