With the rapid development of online education, the differences between online and offline are gradually erased. Recently, the scene of offline “self-study” has been moved to the “online self-study room” on the cloud, which has attracted much attention. Tal, byte beating and other giants have followed up and launched the self-study room function connected with the platform.
So, what is “online study room”? What technical support is needed to build a real-time interactive “online self-study room”? Why does the “online study room” attract many head platforms? Next, let’s dig into the new scene of online education called “online self-study room”.
1、 From punch in to Lianmai learning, there are various forms of online self-study rooms
The concept of online self-study room was not initiated by the online education platform. Previously, the light learning app based on costudy has launched the function of online self-study; The live / social platforms represented by station B and timing also have the scene of users creating online self-study rooms for live / even wheat learning; Tal and other online education platforms connect the online self-study room with the teaching depth to form a new model of “self-study + Q & a”.
- Light self-study mode of Learning + punch in
Represented by light learning apps such as costudy, forest and deskmate, it mainly improves users’ focus on learning by locking the screen, timing learning, punch in and so on. Although there is also the concept of self-study room, even if they are in the same classroom, different users can only interact through adding friends, sending private messages, watching dynamics, etc.

The self-study room on this kind of APP emphasizes reducing the interference of other apps to users to achieve the purpose of auxiliary learning. Therefore, the interaction between users is relatively limited, which is more like a learning tool.
- Online live broadcast / Lianmai learning mode
Represented by live broadcasting / social platforms such as station B and timing, users can open a live broadcasting room to conduct online learning in the form of real-time live broadcasting or multi person wheat connection. Users broadcast their learning status through the camera and supervise each other, so as to improve learning efficiency. In the same self-study room, there are users of real-time live broadcasting / even wheat, and users can also join the self-study room as viewers to learn together.

Although the online self-study room under such scenarios is conducted through live broadcast / continuous wheat, the interaction between users is mainly text or bullet screen communication. The addition of live broadcasting can create a multi person learning atmosphere closer to the offline self-study room. At the same time, it is exposed through the camera, the pressure of “being supervised” increases, and personal behaviors and habits will be more effectively standardized.
- Online self study + Q & a mode
Represented by TAL and other online education platforms, Lianmai self-study is combined with teacher Q & A. The teacher creates an online self-study room and invites 5-20 students to join. When students have questions, they can apply for wheat and communicate 1-to-1 with the teacher.

In this kind of “self-study + Q & a” mode, all interactions are based on live broadcasting / even wheat, and the interaction efficiency is higher. It connects students’ self-study with teachers’ teaching, so that students can get immediate feedback after each self-study and have a more sense of achievement.
2、 What technical support is needed behind the real-time interactive online self-study room?
According to the above introduction, it is not difficult to see that the online education platform prefers the new online self-study mode of “online live broadcast / self-study with wheat + online Q & a”. So what are the requirements for technology from light interactive punch in recording to real-time interactive Lianmai self-study?
- High broadcast quality
Compared with online classroom, although the interaction frequency of online self-study room is low, it also has high requirements for live broadcast quality. For example, it is necessary to support multi person live broadcast, smooth video picture without jamming, real-time synchronization of sound and picture, compatibility with different devices and platforms, adaptive complex network environment, etc.
- Seamlessly switch between live broadcast and continuous broadcast
In addition to the quality of live broadcasting, the online self-study room also needs to realize the seamless switching between live broadcasting and continuous wheat scenes. If students want to ask questions during self-study, they need to switch from live broadcasting to continuous wheat to interact with teachers in real time.
For the above pain points, low latency live (hereinafter referred to as L3) can provide a perfect solution.
- Tens of millions of levels are sent simultaneously, providing a millisecond low latency live broadcast experience
L3 provides the same high concurrency capability as CDN live broadcast of cloud manufacturers, supports tens of millions of concurrent streaming, but only millisecond delay, and can realize real-time synchronization of multi person audio and painting in the scene of online self-study room; Compatible with 15000 + IOS, Android, windows, MacOS and other terminal devices, and bottom adaptation of complex models; Based on the self-learning massive and orderly data network MSDN, it can realize high availability of weak network and stable live interaction under 70% packet loss.
- One API seamlessly switches real-time interactive scenes
That is, the low delay live broadcast product L3 is developed based on zego real-time audio and video SDK. It only needs to call one API to switch between real-time audio and video and low delay live broadcast according to the scene. In the online self-study room scene, students can smoothly switch from the live state during self-study to the wheat state during questioning, which is simple and easy to use and has strong flexibility.
3、 In the post traffic era, user time has become a must for online education platforms
The competition in the online education industry has entered a white hot, and has been comprehensively upgraded from capital reserve, business model and operation mode. According to incomplete statistics, in the last week of 2020, the online education head platform represented by ape counseling, homework help, tal and who to learn from has accumulated more than $6 billion in financing. In terms of advertising, we can see the figure of online education platform, whether it is program sponsorship, video advertising or outdoor advertising. It is conservatively estimated that in 2020, the investment of K12 large classes alone has exceeded 5 billion yuan.
At this stage when the content tends to be homogeneous and the cost of getting customers is rising, in addition to actively looking for new traffic positions and more efficient transformation of getting customers, the online education platform can also break through by prolonging the user life cycle and use time.
Taking the hot AI education track in 2020 as an example, AI interactive courses are widely used in the enlightenment education track, which happens to be a blank business area that has not been touched by the large-scale online education platform before. Through the AI interactive course, the user age group can be extended downward from K12, including preschool users (2-8 years old).

The online self-study room scene can effectively prolong the user’s use time. In the previous online class, students left the application after finishing the class on time. With the addition of online self-study room, students can continue to stay in the application for self-study after completing the online course.
For children, online self-study can improve their learning concentration. Teachers provide Q & A and quickly obtain learning feedback; For parents, online self-study liberates the pressure of tutoring children’s homework and makes the classroom return to the classroom; For the platform, Q & a teachers only need tutors to be competent. There is no pressure on curriculum research and development, and can form a closed loop with existing businesses.
Therefore, once the online self-study room scene is launched, it has attracted the follow-up of many platforms. The follow-up may be connected with the curriculum system and operation system, and become an important link in the online education chain.
From large class, 1v1 teaching, multi person interactive small class, to AI class, super small class, online self-study room… The online education industry has never stopped exploring new scenes and new playing methods. That is, it continues to cultivate the online education industry, help customers implement more innovative scenes and promote the continuous development of the online education industry through excellent audio and video technology and VIP expert services.
