In recent years, led by "digital music", Chinese music market has achieved counterattack and transcendence. According to the 2019 China Online Music Market Monitoring Report released by iMedia Research, by the end of 2018, the total number of music client users in China reached 542 million. However, in the rapid development of music platforms and music anchors, various problems also occur frequently, such as the demand for high-quality services of millions and tens of millions of people online at the same time, and the outbreak of music copyright problems, and so on. It is imperative to "break the game".

On September 6th, in the theme forum of China International Trade in Services Fair 2020 -- "China Music World Stage" Music Industry Development Forum sponsored by People's Daily Digital Communication, organized by Chengdu Hi-Fangwu and supported by Jinshanyun, Zong Jie, general manager of Jinshanyun CDN and Video Cloud Product Center, was the guest at the round table. It also shared how Jinshanyun provides low-level cloud service support for music live streaming, and focused on sharing Jinshanyun's cognition and practice in music copyright protection.
Immersive music live streaming Jinshan Cloud offers a full product technology matrix
"Live streaming plays an important role in the whole music industry," Zong Jie said. Jinshanyun supports more than one million people to watch and listen online at the same time. It can also provide better user service experience and better compliance solutions for the combination of music and video online, which helps the healthy and sustainable development of the live streaming industry.
First of all, Jinshanyun can provide basic IaaS services. No matter ordinary Internet users create and share UGC music videos with a bit rate of 1~2M through the platform in real time, or professional live concerts with a bit rate of 8~10M or even higher, they can be equally distributed through Jinshanyun's computing storage and distribution network covering the world. To deliver content smoothly, steadily and instantly to the end audience.
Secondly, the perfect PaaS product matrix of Jinshanyuyun Video Cloud can provide recording and storage of various video formats, so as to facilitate the retention and playback of live content. Online editing capabilities such as video clip, splicing and format conversion improve the efficiency of content secondary production; Video processing capabilities, such as AI transcoding and video super grading, not only enable audiences in various network environments to share smooth music glugluing, but also achieve high picture quality at low bit rate, saving cloud costs of the platform. Let good live music content with better quality, more refined content permanent retention and dissemination.
In addition, in view of the industry pain point that online interaction is not as good as live experience, Jinshanyun proposes the concept of immersive music live streaming and provides end-to-end VR music live streaming solutions. In VR music live streaming solutions, exquisite algorithm design and powerful edge computing power are used to ensure that the perspective can be switched to high-definition Tile without perception in time when switching. The VR video of 4K music live broadcast can be compressed at around 8M by the technology of smart HD +KSC265. The perception coding technology can well ensure that no block effect occurs in the lighting area, greatly reducing the lag rate of live broadcast. In order to provide users with a better immersive experience, Jinshan Cloud also supports stereo 5.1, 7.1 audio coding and processing services.
"From a technical point of view, during live streaming, you can switch any viewing Angle at any time, listen to any song and watch the highlights of live streaming, which will greatly improve the development of online music live streaming. In the process of future technology development, we will be able to get almost the same immersive experience online as the scene, which will be the future of Kingsoft cloud video cloud bigger and more ultimate goal." "Said Zong Jie.
Music live copyright issues highlight Jinshanyun for safety escort
However, with the increasing demand for the use of music in live streaming videos, live streaming platforms and anchors face rising risks of infringement, and the non-standard use of music works in live streaming has become the focus of attention of all parties in the industry.
As an independent cloud service provider, Jinshan Cloud not only provides stable and accelerated services for the live streaming platform, but also provides technical means for the platform in terms of content security and copyright identification to strengthen the protection of music copyright, so as to help build a sound and healthy positive music live streaming ecology.
It is important for technology platforms to adapt standards and regulations to ensure that every step in the whole process of Internet communication, especially online communication, can effectively monitor whether all content is in conformity with standards, Zong said. On the one hand, DRM can effectively ensure the control of the whole content on different devices; On the other hand, online stored procedures can be effectively monitored and judged. At the same time, AI can identify and protect music copyright in real time instead of blaming it later, which greatly improves the development space of copyright management for live streaming platforms and music copyright owners.
The overall DRM system, encryption technology and effect of Jinshan Cloud are all implemented in the way of audio disruption (using standard cryptographic algorithms such as AES/RSA to encrypt audio files, which cannot be played in other scenes except special decrypters), and can only be played in special decoding terminal, so as to provide a safe service guarantee for the live broadcast platform.
When talking about the charging model of music copyright, Zong Jie said that the charging model of music copyright can be compared with the tiered pricing method of water and electricity, which sets different prices for music resources in the cloud at different stages, which makes the charging of copyright more flexible.
"The music cloud can flow freely in the virtual world like tap water or electricity, which can protect copyright for artists and make it easy for audiences to access content they need. In the future, the efficient flow of all information will lead to a greater development of the entire music streaming industry." Zong Jie finally said.
