What is WebRTC?
WebRTC (Web Real-Time Communication - web real-time communication, is a browser-based real-time multimedia communication technology.
WebRTC was originally a real-time communication solution initiated by Google, which includes video and audio collection, codec, data transmission, audio and video display and other functions. We can quickly build an audio and video communication application through technology.
WebRTC Architecture
What is the difference between WebRTC and RTC?
WebRTC is the easiest to confuse with RTC. In fact, the two cannot be equated.
RTC (Real-time Communications), real-time communication, is a rising industry. After just one year, many players have entered this industry. The most typical applications are live broadcast and real-time audio and video communication. However, many developers are still confused about some concepts, such as RTC and WebRTC, RTC and live broadcast, RTC and IM.
The figure above shows the relationship between RTC and WebRTC, and WebRTC is a part of RTC.
WebRTC only provides basic front-end function implementation, including encoding and decoding and jitter buffering, etc. If developers want to develop commercial projects based on WebRTC, they need to implement and deploy their own server, signaling front-end and back-end selection to implement deployment, and mobile phone A series of specific tasks such as adaptation; in addition to this, a lot of improvement and polishing must be carried out in terms of usability and high quality, and the threshold requirements for its own development capabilities are very high.
A professional RTC technical service system needs not only the above-mentioned communication links, but also a dedicated communication network to solve the instability of the Internet, and a highly tolerant audio and video signal processing algorithm for Internet channels. Of course, the high availability of conventional cloud services, service quality assurance, and monitoring and maintenance tools can only be regarded as the basic modules of a professional service provider.
Therefore, WebRTC is only a combination of several subdivided technologies in the RTC technology stack, not a full-stack solution.
How will RTC develop in the future?
Whether it is RTC or WebRTC, stability is the most basic and important, but there are many factors affecting stability, and there are many problems.
For example, the unavoidable problem of not being able to enter the live broadcast room, if a user’s network is not stable, or it is at the peak of network usage, it is very likely to encounter the problem of not being able to enter the live broadcast room, which is a "fatal" experience for users ; The refund rate and renewal rate in the education industry, the APP uninstall rate and DAU in the entertainment industry will be directly affected.
RTC service providers usually have two approaches.
The first is to transfer the problem to the user's own network, that is, to abandon these users who cannot enter the live broadcast room.
The second is to switch engines. In this way, users who have entered the live broadcast room normally will re-enter the classroom, that is, they will feel that the live broadcast interface suddenly starts to load again or get stuck for a while, which is a bad experience that blocks watching the live broadcast.
Stability is the difficulty the industry is currently facing.
So is there any way to "elegantly" solve the stability problem?
The answer is "Intelligent Fusion RTC".
When users cannot enter the live broadcast room, these users can be automatically dispatched to other RTC engines without any impact on users who have already entered the room. This improves the user experience to the greatest extent, reduces the proportion of customer complaints, and ensures the financial benefits of the enterprise.
Intelligent fusion RTC can solve various stability problems elegantly, which will be the future development trend of RTC.
