Abstract

The invention discloses an audio and video teaching recording and broadcasting system and a control method thereof. The system comprises a plurality of camera devices which are respectively a first camera device, a second camera device, a third camera device, a fourth camera device and a fifth camera device; the fifth camera device is used for carrying out close-up shooting on the blackboard writing content written by a first to-be-detected person and the multimedia courseware displayed by a recording and broadcasting blackboard when the first to-be-detected person writes on the recording andbroadcasting blackboard or displays the multimedia courseware; a control module controls a switching module to switch to the fifth camera device. Blackboard-writing display is carried out on the multimedia courseware displayed on the recording and broadcasting blackboard and the blackboard-writing content of a teacher by using the fifth camera device. The attention of the display area in the recording and broadcasting blackboard can be enhanced. Students listening to classes can timely and quickly watch the current teaching content of the teacher, and thus the classroom teaching efficiency isimproved. The classroom experience of different teaching is met, and the positive learning interest and pleasure of the students can be cultivated.
