In the wake of the epidemic, the development of online education and video conferencing has reached unprecedented levels. Information technology has penetrated into different sectors of society, including the education industry. The traditional education industry is transforming to Internet education, which is bound to face more fierce competition in the future. At present, China’s education methods begin to combine the advantages of offline and online methods, but there are still a lot of breakthroughs to develop into a more perfect online education.
At the beginning of the emergence of live streaming applications, we should understand that the quality of live streaming will be affected by equipment and network environment. In terms of online teaching, this impact will be amplified, that is, the coverage of students will be reduced. The combination of online and offline solutions will minimize such impacts, and in the future, this approach will also produce more innovations.
At present, EasyDSS, the edge architecture product of TSINGSEE Video cloud, provides a comprehensive online education solution, mainly in the aspects of live and recorded videos. Teachers can teach online students live and record and save videos while live broadcasting. It is provided to students who are not timely attending classes due to network environment and other problems, which can save teachers’ time and also provide a more flexible learning way for some learners.
Solved the coverage of online education, the next thing to face is the network transmission problem.
TSINGSEE Video has accumulated deep experience and technical reserves in the audio and video field, and has a complete network transmission system and information encryption system, which provides a good foundation for the quality of online teaching. EasyDSS online classroom education system carries out audio and video data transmission through RTMP protocol. Although distribution through CDN needs to break through the delay problem, we can still play all terminals directly through EasyDSS, including mobile phones, computers, even TV and other available terminal devices.
In the aspect of system, many education platform will have to use more downtime when encountered problems, take the outbreak last year, a large number of online training needs will appear at the same time, early in the preparation of a variety of hardware and software resources are insufficient to deal with, the online education system is easy to drop, caton, even unable to run directly.
The current stability of EasyDSS is enough to meet the demand of online education at the present stage, supporting the collection and push distribution of 100 channels of video stream. In addition to live broadcast, the on-demand function also has good practicability.
Online education is still at the growth stage, although the “live + education” can approximatively achieve “face to face”, but still there are some problems, for example, learners’ learning environment is relatively single, such as the limited interaction between learners and learners, in the later development, EasyDSS may combine the present popular VR, AR, such as technology, Realize deeper technology application, provide educators and learners with a more convenient interaction, more friendly experience of video transmission platform.
