Program Background
The national government has been actively promoting the development of digital classrooms in primary and secondary schools. This initiative has led to the provision of advanced software and hardware facilities, enhancing the educational environment and improving the management of digital applications in teaching. As a result, a digital campus system has been established, becoming an essential tool for modern education. With the growing availability of online course materials, teachers now have access to more diverse and rich content for classroom instruction. The recording and sharing of high-quality courses have become vital tools for raising the overall standard of regional education. However, the current challenge lies in the lack of video resources—especially localized, high-quality ones—which hinders the balanced development of education. Therefore, the construction of high-quality courses, the recording of these courses, and the establishment of online video platforms have become urgent priorities.
System Overview
The automatic recording and broadcasting system leverages cutting-edge technologies such as image analysis, tracking, audio noise reduction, multi-scene switching, and intelligent control. It is designed for use in professional classrooms, enabling accurate reproduction of classroom scenes and effectively addressing the challenges of recording and accumulating school-based educational resources.
The entire process of recording and broadcasting is user-friendly and efficient, with one-click operation that minimizes complexity, enhances system stability, and reduces the workload on staff managing classroom recordings. This makes the system both simple and intuitive to use.
In recent years, the Dulwich Automatic Recording and Broadcasting System has gained widespread adoption across universities and primary and secondary schools nationwide, including institutions like Beijing Institute of Clothing Technology, Beijing University of Technology, Cambridge Middle School, Normal University Affiliated School, Nanfeng Primary and Secondary School, Yang Yizhong School, Sun Wuzhen Middle School, and Chengxi Middle School.
