The teacher-student interaction is not only a key point in teaching, but also an important indicator for evaluating classroom teaching quality. It can reproduce the accurate and complete classroom interactive teaching, and truly realize the quality of classroom teaching, which is the basis of recording and broadcasting system. With the improvement of education information and the application of high-quality teaching methods, the teaching level of teachers has been greatly improved compared with the past. With the quality of courses improved qualitatively, more and more teachers’ courses have been incorporated into excellent courses. However, from the perspective of school-based resource construction, the existing software and hardware recording conditions and the number of video shooting staff are far from meeting the actual recording quality and quantity requirements. Therefore, it requires an advanced course recording system to solve the current problems fundamentally: the limitation on recording conditions and the number of photographers. In this way, it can realize the normalization of course recording and course accumulation. For example: there are two classrooms with 30 square meters each for 20 students, one of which is a recording room.
