The establishment of recording and broadcasting classrooms has become a key initiative in the digital transformation of campus infrastructure, following the rollout of multimedia classrooms. These classrooms are designed to capture various signals such as lectures, instructors' images, audio, and classroom interactions using advanced hardware. The recorded content is then converted into standard network formats, enabling users to stream or download it on demand. Once completed, these classrooms will support comprehensive, three-dimensional recording, editing, on-demand playback, and live streaming of both teacher-led instruction and student engagement. This not only helps in building a rich collection of multimedia teaching materials but also enhances the development of school-specific resources. It provides strong support for post-class activities, teaching research, and analysis, helping teachers improve their instructional methods. Additionally, it facilitates students’ review after class and promotes resource sharing between remote universities.
