The emergence of "smart recording and broadcasting system" is a revolutionary change in the traditional classroom teaching video method, completely solving the complexity of manual shooting and the interference to classroom teaching. At the same time, the "smart recording and broadcasting system" can integrate the electronic whiteboard well. Multimedia teaching equipment such as computer screens, the teaching courseware is clearly and completely displayed, which is not achieved by the traditional classroom video recording method; with the popularity of the network, the "smart mobile recording and broadcasting system" can broadcast the classroom teaching process online and broaden it. The scope of the classroom has improved the sharing degree of high-quality teaching resources, greatly improved the utilization efficiency of educational resources, and provided a brand-new way for classroom teaching videos. However, the "smart recording and broadcasting system" is different from the ordinary multimedia teaching equipment, the system is more complicated, and the standard is not uniform. The Nanjing mobile recording and broadcasting system has:
First, automatic and manual flexible combination
The “smart recording and broadcasting system†appeared in order to overcome the shortcomings of the traditional classroom recording method, and achieved “automatic†classroom recording without any human intervention. But the reality is that in some cases, proper manual intervention may work better. The intelligent recording and broadcasting system allows appropriate manual intervention, manual control of camera lens movement and zooming, manual control of lens switching, etc.; each channel of audio and video signals can be saved, allowing for subsequent processing, re-editing and compositing. , greatly improving the flexibility of shooting.
Second, attach importance to communication and interaction
In the past, when the "Intelligent Recording and Broadcasting System" was used for live webcasting, the client user could only receive signals in one direction, but could not feedback the signal, and could not interact with the network on the spot. This is a disadvantage in some cases. For example, teachers can teach students on the Internet through the “Intelligent Recording and Broadcasting Systemâ€, and teachers cannot get feedback from students. Information feedback is crucial to improve the quality of classroom teaching. With the feedback of students, it is possible to target students with targeted teaching and improve the effectiveness of teaching.
Third, courseware on-demand humanization
The courseware generated through the "smart recording and broadcasting system" is finally put on the network for everyone to learn. This raises a question, and what can be done is more conducive to student learning. The current "knowledge point index auto-generation" technology is a convenient student technology. During the courseware recording process, the “Smart Recording System†can automatically generate knowledge point indexes, and can also perform post-editing, which greatly facilitates students. Because learning courseware is different from watching movies, it is rarely seen from the beginning. Most of them are selective learning, so the index of knowledge points is very important. Just like reading a book, you can get a general understanding of the content and structure of the book by looking at the catalog. It can be read selectively. With the "automatic generation of knowledge points index" technology, students can select the parts they need to learn according to their own needs and improve their learning efficiency.
Fourth, fit the needs of primary and secondary schools
With the development of technology, the "smart recording and broadcasting system" has gradually matured from immature, and through the application practice of users, it has continuously found problems and solved problems. The "smart recording and broadcasting system" has gradually been recognized and accepted by everyone. "Intelligent Recording and Broadcasting System" was originally developed with the construction of high-quality courses in higher education institutions and popularized in higher education institutions. However, in today's educational environment, primary and secondary schools have also begun to pay attention to intelligent recording and broadcasting products. The intelligent recording and broadcasting system fits the needs of primary and secondary schools, and tailors the recording and broadcasting products suitable for primary and secondary schools. It will play an increasingly important role in the education and teaching of primary and secondary schools.
