The Economist(Economist)_ In_The World in 2021In the editor’s preface of the special issue:“21It’s a number associated with luck, adventure, opportunity and dice – it’s the sum of the six numbers on a standard dice_（ That is, the sum of the first six natural numbers 1 + 2 + 3 + 4 + 5 + 6 = 21, also known as triangle number).
And Wikipedia tells us,21It is the number of sunlight in the Kude flag; Is the atomic number of the chemical element scandium; Is the minimum nontrivial number of Fibonacci sequence; Is forFTPStandard of connectionTCP/IPPort number.
In addition,21Gram is also considered to be the weight of the soul.
All this is strangely related to this unusual year——2021It brings great uncertainty from far to near – the risk has not become smaller, but it brings new wind and new demand – the demand stimulates the market and new business opportunities – andTechnology itself,This is where the iteration starts to speed up.
Here’s howThe year 2021 that livevideostack is most concerned about_（ (incomplete)_Audio and video technology trends,YesLivevideostackcon 2021 Shanghai Station – new technology, new opportunities – focus on technology hot spots.
As for edge computing, most people will not deny that it represents the future, not only because of the huge network cost of centralized architecture, but also because of the increasingly demanding demand of users for delay. But to achieve a coordinated architecture between the edge and the center, it will take time and more investment from the platform side – just likeAWSAnd the same challenges that cloud vendors face in the early days of cloud computing.
5GInfrastructure construction will lay a key foundation for edge computing; Key application scenarios and killer applications will really become a force driving the development of edge computing, such as the demand for network delay in the industrial field, the demand for massive edge computing nodes in cloud games, the demand for ultra-high bandwidth in ultra-high definition or VR video, and so on.
This time, livevideostackcon 2021 Shanghai station will share more current business scenarios and future application examples related to edge computing.
Real time audio and video communication, cloud games, ultra high definition video, VR / AR and other applications and scenarios are all supported by low delay from the beginning to the end. In order to achieve ultra-low delay, it is not only reflected in the iterative upgrading of terminal equipment, hardware acceleration and the continuous optimization of underlying codec, but also the upgrading of network architecture, the optimization of transmission protocol, the choice of link strategy and so on.
The coming of 5g and 8K Era_（ Or coming, It not only brings the improvement of transmission bandwidth and terminal computing ability, but also makes rapid development of VR / AR, immersive and high degree of freedom video technology. From high frame rate to high resolution to today’s HDR, we continue to pursue the ultimate image quality, which further brings a new sense of reality and interactive experience. At present, AR / VR has been verified in many education and training scenarios, and is in the transition to pan entertainment. Perhaps in the next 1-2 years, the short video viewing experience of VR effect will be popularized.
Nowadays, it seems that every software investment and product PR should be mentioned“No code”Platform or function. Similar to cloud computing, no code itself is not an inherent category, rather than a categoryIt is a change in the way users interact with software tools。 Just as PC popularizes the use of software, API popularizes software connection, and cloud popularizes the purchase and deployment of software, codeless may lead the next wave of enterprise innovation by popularizing specific technical skills.
Internet Co, such as Kwai Fu and sonic network, have also set up a special team to develop “no code / low code” projects.
“Low code_（ Low Code）_” And“No code_（ No Code）_” They are often mentioned interchangeably, but their concepts are quite different. Both low code and no code abstract the underlying code and its technicality. Low code aims to improve the efficiency of developers through limited abstraction, while no code wants to enhance the ability of developers and non-technical personnel through more powerful abstraction.
According to Forrester Research, by 2020,84% of enterprises have started to use low code / no code technologyAccording to Gartner,By 2024, low code / no code will account for 65% of all application development.
All along, audio related technology_（ No matter hardware or software)_ Sharing is relatively small, but the pursuit of human ears for sound quality is getting higher and higher: both AI noise reduction and echo cancellation in RTC scenes, digital signal processing for TWS headphones and more futuristic audio VR technology are attracting more and more attention. So far, there is no general solution and evaluation standard for Audio Algorithm and transmission in RTC scene, but at the same time, we also see more and more investment in audio technology.
In this Shanghai Station“New audio experience”For the first time, we expanded the Audio theme to seven sessions a day, which are divided into two half day sessions of hardware and software. The content involves the audio experience of cloud video conference, noise control based on deep learning, audio algorithm of mobile phone player and hardware system, automatic mouth generation project supporting multi platform and multi language, and follow-up_（ (after Spring Festival)_ More lecturers and sharing topics will be identified in succession_（ Please look forward to it.
With the rapid growth of the demand for video content, the amount of transmission on the network is also increasing – tens or hundreds of megabytes of bit rate, which puts forward higher requirements for video codec computing power. contrastGPU、FPGA、ASICFrom the aspects of delay control and energy consumption,ASICAcceleration seems to be a better choice, but customization makes its early investment not to be underestimated. Therefore,GPUandFPGAIt still maintains an indispensable advantage and position in specific scenarios.
Tiktok change rapidly with the rapid development of multimedia technology, and the content form and demand are changing and growing. The rise of the video platform such as shaking, Kwai, B station has greatly satisfied people’s spiritual needs. However, content production is often limited by the energy and imagination of the creator, and it is difficult to continuously supply high-quality content at high frequency. From Google’surl2videoTo BaiduVidPress, fromNLP、TTSWhen Netease AI generates the song wake up, the innovation of multimedia technology is pushing the automatic intelligent production to people’s daily life, and providing more yuan and more interesting audio and video content. At the same time, the continuous upgrading of multimedia consumption in the future will also promote the automatic production tools to usher in a faster development cycle and better content experience.
Low latency streaming data processing framework, embedded software media processing framework, OWT, ffmpeg, GStreamer, SRS, webrtc, VVC, AV1
No need to say more.
Finally, we use Mr. Zhu Zheng, the co-founder and CEO of microframe technology, as an example_“Technology and business strategy” roundtable of livevideostackcon 2021 Shanghai Station_ At the end of the topic Description:
“The outbreak of the storm swept the world, changing people’s production and lifestyle. Many companies are seeking development in difficulties, and many companies are standing on the crest of the waves in prosperity. The era of video is accelerating, and new multimedia technologies, products and applications are constantly emerging.Waves and windHow to find opportunities in the fierce challenges?Blowing all the sandHow to transform technology into business value?”
In 2021, livevideostack hopes to keep moving forward with you, looking for answers.
