With the popularization of the teaching of electrification and the introduction of the teaching of the in-school TV in the classroom, the playing volume of the television video is getting larger and larger. The playing mode is also developed from purely regular play to controlled play by the teacher at any time according to the lectures. The continuous enrichment of video recording materials and the complicated management of video equipment put forward higher requirements for CCTV teaching. The system uses computer technology to achieve the classroom and the central play room data communications and calls, to classrooms and playroom to the bilateral control of the recorder. In this way, teachers can make full use of video information, at any time inserted, changing the situation of the TV play and classroom teaching.
