2 month 25 Japan , The video cloud technology force summit hosted by volcanic engine was held in Beijing . Summit to " Ride the cloud · World view "" The theme of , The person in charge of volcanic engine shared the experience of video 、 Interaction 、 Observation and thinking of growth , And release a new product matrix of experience oriented video cloud .
Industry wide video The ultimate video experience has become the key to business growth
According to the IDC released 《 Insight into the development trend of video cloud 》, Digital age , From business activities to social life , Video data has become a way to connect individuals 、 family 、 An important link between the community and even society .
IDC Wei Yunfeng, China Research Manager, said , Along with 5G、AI、4K/8K Etc , Car networking 、 The Internet of things 、 Video networking enables audio and video applications to change from traditional video scenes , Gradually expand to on-board video 、 New application scenarios such as smart home , The video trend of the whole industry has taken shape .
In this context , End users' requirements for audio and video technology began to emphasize high-definition 、 Interactive 、 Immersive all-round experience .
For different industries , Creating high-quality user experience is also different due to the differences of industry attributes . The demand of radio and television media industry is more inclined to automatic content production , The retail e-commerce industry pays more attention to the smoothness and interactivity of video , so to speak , The demand for video experience from all walks of life runs through video production 、 Video storage 、 Video distribution and even terminals / The whole process of application video streaming .

Tan Dai, general manager of volcanic engine, said , The volcano engine vibrate through its tiktok. 、 Watermelon Video 、 Tomato novel 、 Flying books and other products precipitate excellent ability , Including video on demand 、 Live video 、 Real time audio and video 、 Edge of computing 、veImageX Products such as , It can meet the requirements of customers for video capacity-building .
Volcano engine video cloud contains pan Internet 、 game 、 Finance 、 Radio and television scenes and Solutions , video on demand 、veImageX、 Core products such as real-time audio and video , And the transmission network 、 Intelligent production 、 Intelligent processing and other middle desk support services .
besides , The volcano engine video cloud also supports virtual idol concerts 、 digital double Avatar、 Tiktok and other practical functions . The virtual idol concert supports real-time interaction with the virtual idol anchor , Bring the audience a new experience of cross dimensional communication ; digital double Avatar Support the setting of virtual human image and interaction on social platform , Can reduce creative costs , Increase the appeal of content ; Tiktok function supports all users in the room. , Watch tiktok short video with the same progress. , Enhance the interest of the room , Create a sense of company . These interesting and innovative ways to play , Can help the enterprise's user growth in practical application .
Establish quantitative indicators , Create experience oriented video cloud
" Experience oriented " It is a feature of volcanic engine video cloud . The person in charge of volcanic engine video cloud technology said , To evaluate and improve the experience , The first step is to be able to quantify the experience ," We need accurate indicators as a compass , Accurately reflect the relationship between experience Optimization and business data , Optimize in the right direction , To continuously improve the experience ."
Volcano engine play from 、 Picture quality 、 Interaction 、 Four dimensions of performance , Quantify and evaluate video experience .
In terms of playback experience , Volcano engine video cloud compresses the first frame time to 100ms following , The user does not feel that the first frame exists . And related technologies have higher stability , The crash rate has been reduced to 1/100000 following , If users brush every day 100 A short video ,3 Only once in a year can we encounter a player crash .
Image quality experience , Volcano engine BVC1 Encoder comparison H265 Can save 50% Bit rate of , Under the same bandwidth BVC1 The image quality of the encoder is clearer . It is reported that , In terms of image quality, volcanic engine has invested a lot of R & D resources , In video codec, the world's top events MSU2020 in , Volcanic engine development BVC Series encoder obtained 17 Item scoring champion . And in order to quantify image quality , Volcanic engine self-developed VQScore Algorithm , Also in the ICME 2021 Of " Compress UGC Video quality assessment " In the game , get " No reference video quality evaluation （NR-VQA）MOS Track " The first name .
Interactive experience , Volcano engine video cloud integrates tiktok beauty. 、 Special effects 、 Best practices for filter application , Make video production easier , Make user interaction more interesting . in addition , Real time audio and video services （RTC technology ） Support millions of concurrent users , A single room can support more than 1000 people , It has become the first one in China that can provide more than 1000 people with wheat in a single room RTC service .
Performance experience , Volcano engine video cloud can provide services for business scenarios SDK Parameter configuration 、 Best practices for bit rate configuration , Greatly improved H265 Percentage of playback ; Its self-developed image codec algorithm has better effect , The compressed volume can be re optimized compared with the mainstream products in the industry 10%-20%; meanwhile , HD low code technology makes the source compression rate up to 20%-35%, Under the same subjective effect , Save bit rate 10%-20%.
The scene , The volcanic engine also cooperates with Alibaba cloud 、 Tencent cloud upgrades the live broadcast technology standard , Issued the signaling standard of ultra-low delay live broadcast protocol , Shorten the live broadcast delay in ten million level concurrent scenarios to 1 Seconds , Solved the traditional live broadcast 3 To 6 Second delay problem . This technology can be widely used in live events 、 Online education 、 Live broadcast of e-commerce and other scenes requiring high real-time performance , Bring ultra-low delay to users 、 Low carton 、 Second open smooth live experience . Volcanic engine and aliyun 、 Tencent cloud has opened all protocol interaction details , It is convenient for the industry to smoothly upgrade the live broadcast technical standards , Build a prosperous low delay live broadcasting ecology .
