Program Background
The country has been actively promoting the construction of digital classrooms in primary and secondary schools, providing advanced software and hardware facilities to support education and teaching. This initiative emphasizes the digitalization of campus management, creating a comprehensive digital learning environment that enhances the quality of 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 lessons have become essential tools for improving regional educational standards. However, the current challenge lies in the lack of localized video resources, which hinders the balanced development of education. As a result, the need for high-quality course creation, professional recording, and the establishment of online video platforms has never been more urgent.
System Overview
The automatic recording and broadcasting system leverages cutting-edge technologies such as image analysis, intelligent noise reduction, multi-scene switching, and smart control. It is designed for use in specialized classrooms, enabling accurate reproduction of classroom activities and addressing challenges related to curriculum recording and resource accumulation. The entire process is simple and efficient, with one-click operation that reduces complexity, improves stability, and makes the system user-friendly. This minimizes the workload for staff managing classroom recordings, making it easier to maintain and operate. In recent years, the Dulwich Automatic Recording and Broadcasting System has been widely adopted across universities and schools nationwide, including 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.
