How to make the open class unimpeded? All the time, the entire recording and broadcasting industry has been diligently seeking. The development of recording and broadcasting technology also affects the hearts of educators. I believe everyone has a deep memory. At the beginning of the 1990s and last century, many units built their own informatization, including resource management, and various systems. By 2004 and 2005, the systems that emerged at that time, different systems The inability to work with each other has formed a misleading information. There are three levels to connect these:
First, between the recording and the application, a variety of intelligent campus management software systems, they are very closely integrated with the teacher's work. Second, between recording and broadcasting equipment. The third recording and broadcasting equipment is integrated with the manufacturer.
In this recording and broadcasting circle, who is the protagonist and the user is the protagonist! Both developers and recording manufacturers want to use themselves as a center for everyone to use, but I think we should take a look at what users need. What, our current situation may be like what Mr. Zhong said just now, there are a lot of information misleading, there are various systems in the school, the teacher is already used to it, he is not willing to always change, then many software companies, according to the school He tailored a variety of software to meet the requirements of the existing use, but he did not have the recording function, the software opener and the recording manufacturer could not coordinate, resulting in the recording system to manage the surrounding resources The platforms are all plugged in, it is difficult for everyone to re-learn a new system, which has caused the school to be very upset, and hope that users can easily integrate the software of different developers in the future, you can think about it, if you can Accept the existing system control, including the user management and resource management can be integrated into it, which is very perfect, we can It can be said that this recording and broadcasting system is a separate recording and broadcasting system. For users, it's just that there is an additional recording system in his habitual program. Some companies can provide software that meets the needs of the school. Users don't know why there is an additional recording system, instead of re-learning. Of course, this technology There must be his difficulties. A common pass is a bit difficult.
Second, the opening and integration of recording and broadcasting equipment, what is the most demanded by users, I get information, mainly engaged in this research and development work, the information I get is interactive, only you can interact, the students who attend the class can have He feels immersive, he can communicate with the teacher according to his own situation. Everyone will say, can I use a video conference and add a recording and broadcasting system? Is this a lot of drawbacks? This is a repeated investment. Because he is two systems, second, it is difficult to unify the management, how do the different systems fit together, third, the video is not suitable for our teaching, and fourth, the operation is cumbersome.
If we refer to the video conference system in terms of interactive core requirements, we focus on video conferences, and we cannot master this technology when setting up a recording and broadcasting system.
As we all know, the recording and broadcasting bridge is the "Great Leap Forward" of the current recording and broadcasting technology. We build a bridge for streaming media sharing for seemingly independent recording and broadcasting equipment. We need to think about how to share.
If we have two AB campuses, they both have a recording and broadcasting system. When they have interactive needs, we can better show our teaching scenarios. This is technically difficult, because of network factors, there are different How to solve the connection technology between the recording and broadcasting systems. At present, what we can achieve is that the round-trip delay does not exceed 0.5 seconds, and the face-to-face conversation does not feel uncomfortable.
In the recording and broadcasting bridge, what can we connect in? I connect two separate sets of equipment to each other to form a terminal between each other. Only in this way can we achieve openness and integration. Independent recording system + recording bridge = video conference.
The trend involved in the system is simple operation, high scalability, and user experience.
We want to better serve users through open integration.
Let our recording system broadcast more widely.
The former deputy director of the Beijing University of Technology Modern Education Technology and Network Center, Zuoqu said that the previous quality classrooms were provided to meet the requirements of resource sharing among college students, and now it is to meet the learning of students and open to the society at the same time, the purpose is to achieve science and technology Promotion, in this sense, open courses seem to be more demanding. From the perspective of various schools, the construction of high-quality open courses, and resource sharing, it is manufacturers who propose their products for better development.
The content of the open class, if teachers want to see what students want to see, the recording and broadcasting system should do a better job, from the technical indicators, meet the requirements of video, audio requirements, etc. This is a requirement as an open class Now, more about application requirements, including documents from the Ministry of Education also say that the grasp of content should be paid attention to. From a technical point of view, including video, technical requirements, etc. these requirements are the most basic part. Recording, including video, remote interactive teaching. Recording and broadcasting manufacturers have been doing it for more than ten years and have accumulated a lot of experience and products. No matter what occasions these products are used, in the end, in terms of the production of open classes, it is crucial to provide better products to meet the needs of students. Ideas. In the final analysis, technology and recording equipment must be very good.
There are 9500 lessons in primary and secondary schools. After all, we are colleges and universities. What is the significance of primary and secondary schools? The Ministry of Education does open video classes. His core value is the sharing of high-quality resources. University also has such people who reflect that my teacher may not be able to teach bad Level, in primary and secondary schools, especially in underdeveloped and underdeveloped areas, the teacher ’s education level may not be high, how can he allow students to effectively master the knowledge, the level of teachers who are taught by high-level teachers is not the same, in the final analysis: Policy, this is definitely a very good idea. Students benefit most from this technology.
In this age of streaming media, we must have a classroom feeling. Broadcast teaching and video conferencing courses jointly construct a new motivation for the classroom. But the constraints of technical architecture and the communication between teachers may be the next problem to be solved.
