Writing on “Cloud” Creek | Video Industrialization Has Completed the Transition Period, and the “Immersive Video Cloud” Era Is Coming
Start by popularizing science“Cold knowledge”:2018year8In January, the usage time of users in the online video field surpassed the social sector for the first time, becoming the largest field in the entire network.
globallyCDNThe usage also confirms this:2017Since the beginning of the year, the video cloud traffic market has remained70%The above rapid growth. And according toCisco VNIdata forecasting, from2021At the beginning of the year, this number will rise to80%。
A series of numbers woke people up like a dream: it turns out we spend so much time on video every day!
Obviously, after the transition period, the video cloud market not only shows no signs of slowing down; on the contrary, Vietnam is becoming more brave, and is about to usher in a new round of peak traffic.
Expected in5GIn this era, immersive video business scenarios based on ultra-high definition and low-latency interaction will continue to emerge and evolve, becoming the main force in the video industry.
This series of changes, as stated in the “China Video Socialization Trend Report” released in 2020: “After experiencing the 'film and television video era', the informatization and mobility of the 'online video era' have continuously accelerated the video industrialization process. Based on technological innovation, industrial upgrading, and more macro-level driving forces, we are accelerating into a brand new one'Age of Impression'。”
1、Why is it time for video to evolve?
The colorful flowers are becoming more and more enchanting,Live videoThe brightest.
this2020, how many live broadcasts have you seen to bring the goods to life?
Stimulated by the pandemic, live video streaming has taken over traffic dividends as a new business format, growing into an official standard and infrastructure to drive economic development and recovery, to attracting a large number of players and entrants from different fields. The major platforms are also working hard to break out of their fame.
At the beginning of Double Eleven last year, leading anchors such as Via, Li Jiaqi, and Luo Yonghao brought in nearly 10 billion yuan in goods. Also at the same stage, the number of e-commerce live streaming users exceeded 300 million.According to data from Ai Media Consulting, the e-commerce live streaming market is expected to reach 961 billion yuan this year, which is about to break the trillion mark, an increase of 122% over the previous year.
Not only live streaming brings goods, video conferencing, online education, cloud gaming,AR/VRAll in2020The year was in the limelight. All parties in the market have seen that the utility properties of video are on the rise and can directly serve the real economy and economic transformation. cloud computing,5G、AISuch developments will further break the cost and technical threshold of video production.
In addition to being an important medium of communication, video is also constantly undergoing new changes in content production. Not only in various vertical industries, a large numberUGC ((That is, content output by users) content has also sprung up, and the entire video industry is improving.
But when the dividends and boom in the industry wear off, technological innovation is essential if we want to continue to stand firm and dominate.
2、How to meet the development needs of the new era of video?
Technological innovation and development are an important driving force for video to enter all fields of production and life.
In the early days of the video industry, the production and distribution of movies and television was monopolized by professional mass media organizations, and viewers were unable to interact further. With the development of informatization and mobility, the frequency of use of shooting terminals such as cameras and mobile phones has rapidly increased, video creation and sharing platforms have risen, and the era of “everyone can shoot, everything can be shot” has arrived. The way people interact has evolved from text, images, and audio to more vivid and immersive forms of interaction such as short videos, high-definition video, and AR/VR.
According to the “China Video Cloud Market Tracking (First Half of 2020)” report released by IDC, China's video cloud market reached 3.16 billion US dollars in the first half of 2020, with a year-on-year increase of 58.6%.Among them, the video cloud solutions market was the most prominent, with a year-on-year increase of more than 70%.
Compared with the forecast made in the previous cycle, IDC improved the forecast data for the whole of 2020 and the long-term forecast data based on the actual situation in the first half of 2020. The sharp rise in demand for online interactive entertainment and live streaming delivery, and the immediate demand for video cloud solutions in non-Internet industries such as education, media, and finance have become key factors driving market growth.
This trend means that the “immersive video cloud” is a new ecological-level industry that is rising and entering a moment of explosion.
As a result, as providers of underlying infrastructure such as computing and transmission, cloud vendors' computing power support and architectural support have become secret weapons to meet this immediate need.
The reason is that mobile networks and optical fiber networks have limited broadband, and traditional data centers are difficult to expand, have low flexibility, and high cost, making it difficult to meet the development needs of high-definition, high-interaction, and high-real-time video.
However, cloud computing architectures have the characteristics of flexible expansion, stability, and high reuse, and are favored by customers. Of course, those who can finally conquer the market have never been “generals” with no external skills or internal strength, but “martial arts masters” who have both internal and external skills.
In addition to architecture, top cloud vendors have extensive experience in cutting-edge technologies such as cloud coding and decoding, AI applications, and edge computing, and have specific solutions for video applications.
For example $Kingsoft Cloud(KC.US$The development strategy of the video cloud “upward AI and downward marginalization” was clarified very early on. Based on HD, VR, and interaction, a comprehensive layout was carried out at the IaaS and PaaS layers to help enterprises create more immersive video experiences.
3、How does Jinshan Cloud build a “dynamic moat” for video clouds?
The market is changing, technology continues to be iterated, and any successful enterprise faces known and unknown challenges, so building a “moat” is the foundation to ensure that it can stand strong. However, it is becoming more and more difficult for today's enterprises to rely on a single barrier similar to marketing, model, or brand to build a moat. Zhang Lei put forward the idea of a “dynamic moat” in the “Value” article. He believes, “There is only one moat in the world, where entrepreneurs continue to innovate and frantically create long-term value.”
After we dismantled the “Immersive Video Cloud” service, it was easy to find that the most correct thing Jinshan Cloud did was to build a “dynamic moat”. This is the key reason why it is still in the first tier of video clouds in the face of wave after wave of shocks.
From a biological point of view, meeting the true immersive requirements of the human eye with 50k resolution, 120fps bitrate, and 10-bit color gamut will pose a huge challenge to video codec and transmission.
So first of all, if you want to achieve an “immersive experience,” Ultra HD is a must. Take VR videos as an example. Over the past few years, VR has always brought users some dizziness or visual fatigue. The biggest reason is that UHD technology lacks better use. Future VR must use ultra-clear technology to ensure realism.
Meanwhile, Jinshan Cloud has multiple sets of products such as JiZhi HD, KSC265, KIE, and KAV1. Jizhi HD combines the KSC265 coding method independently developed by Jinshanyun, which can reduce the HD video bitrate by 60%, solving the problem of consumer viewing stuttering and the bandwidth costs of video providers.
It is worth mentioning that the Jinshanyun AV1 codec technology, which recently made a splash at MSU, can continue to increase the compression ratio by 10%-20% compared to the baseline level of KSC265 while ensuring high-definition image quality. At the same time, it can meet the smooth transmission of 8K VR 100 megabytes, help 4K high-definition video users upgrade to 100 million color levels (10 bits), and greatly help users improve the viewing experience.
Jinshan Cloud Tile Solution has low decoding power consumption, smaller block coding bandwidth, and saves 75% in bit rate. At the same time, Jinshan Cloud's VR FOV transmission solution can cut the original video into chunks, encode and distribute different bit rates separately. While drastically reducing the video transmission bit rate, the viewing angle switching delay can be controlled within 30-60 ms, effectively eliminating motion.
Second, interactivity has been proven to be a reasonable direction by the recent popularity of live video broadcasts. The challenge posed by interaction is low latency.
According to information, Jinshan Cloud Edge Computing provides low latency access of less than 15 ms, good cross-network route optimization and scheduling capabilities, efficient transmission of audio and video data streams, and strong computing power support. RTC combines Jinshan Cloud Edge Network technology to effectively eliminate jitter in video and achieve a lower latency interactive experience. More than that, the decentralized network topology of the Jinshan Cloud LiveNet edge network greatly improves network stability; dynamic scheduling of a wide range of edge computing nodes and networks makes the edge network more intelligent. The LiveNet network eliminates RTC communication network jitter and supports one-click non-intrusive access. Intelligent operation and maintenance allows users to adjust network status without perception.
Finally, network distribution capabilities play an essential role in high traffic spikes.
Jinshan Cloud, on the other hand, has rich CDN and edge computing nodes and network optimization technology. In order to cope with network jitter, the Jinshan Cloud TCP network has been optimized to increase transmission efficiency by 30%, and support for the QUIC protocol has greatly improved download speed even when the network is weak.
At the same time, at the AI level, Jinshan Cloud has integrated AI into every detail of the video cloud. For example, Jinshan Cloud CDN seamlessly connects with AI product image enhancement and intelligent HD to build rich media ultra-clear solutions that can improve video and image quality and reduce bandwidth costs; Jinshan Cloud's image enhancement engine KIE can use techniques such as super resolution and image quality restoration to superdivide low-resolution images into high-definition images, greatly improving the viewing experience, and saving image transmission bandwidth costs, etc.
By empowering the three dimensions of Ultra HD, VR, and interactive technology, Jinshan Cloud has formed a comprehensive immersive video cloud matrix.This evolutionary technological restructuring has opened up a direction for the high-dimensional expansion of the entire video cloud industry.
4.Standing at the starting point of change,Rediscover the video cloud
“In the future, 80% of content on the Internet will be video-based.” Based on the natural sensitivity of cloud computing companies to data, Wang Yulin, CEO of Jinshan Cloud, said, “We need to balance industry trends with technological trends. As video product service capabilities continue to improve, it can gradually penetrate into different industries.”
In the long run, Covid-19 has fundamentally affected and even changed how production, life, and business are organized, and contactless business connections are rapidly emerging around the world.
This is an indelible trend:From the consumer Internet to the industrial Internet, application scenarios have been opened up, and Internet-related technologies such as video will be further integrated and served in the real world.
The northernmost highway on Earth is the Dampster Highway from Canada to the Arctic Circle. There is a saying at the end of the road: At this point, there is no road, and your story has only just begun.
The end of the road is a new starting point; the peak of the mountain is a new journey. After the transition period, the “immersive video cloud” industry transformation has only just begun.
