This paper analyzes the architecture of automatic intelligent recording and broadcasting system, the scheme of automatic tracking and location shooting of camera, student video camera and blackboard camera and the scheme of synchronous pickup (recording). The principle of automatic editing system is expounded. The basis and application of MPEG-4 and H.264 video compression coding are compared. Streaming media transmission technology is widely used in distance education, remote monitoring and remote video conferencing. Finally, the minimum technical requirements of automatic intelligent recording and broadcasting system are given.
