The invention relates to a digital voice recording and broadcasting teaching system, which comprises a main teaching unit which is used by teachers, an auxiliary subunit, a shooting module and a positioner. The teaching system also comprises a teaching strategy processing module and a recording and broadcasting strategy processing module, wherein the teaching strategy processing module analyzes teaching operations of the main teaching unit and the auxiliary subunit and determines information whether to perform scene and shot change, and the recording and broadcasting strategy processing modulecontrols the corresponding shooting module according to output information of the positioner, calculates the focal length of shooting lens, the shooting angle and the shooting effect, and takes a picture of the behaviors of the teachers or students if scene and shot change is required, so that the effect of intelligent shooting is realized and the aim of bidirectional omnibearing video communication of the teachers and the students is achieved. Simultaneously, the system can also directly broadcast shot videos on the internet through a direct broadcasting module, so that users on the outsidesof classrooms can participate in teaching activities through the internet.
Description
technical field [0001] The invention relates to a digital voice recording and broadcasting teaching system and a control method, in particular to a digital voice recording and broadcasting teaching system and a control method capable of tracking shooting, video recording and live broadcasting. Background technique [0002] Existing teaching assistant systems such as multimedia, digital teaching, and voice classrooms can usually only complete simple teaching tasks, that is, they only allow students to communicate with the main teaching system or with teachers in two-way or one-way, and cannot automatically control the teaching activities. Center (behavior of students or teachers) to track the video, so that the purpose of two-way omni-directional video communication between teachers and students cannot be achieved, which is not conducive to improving the quality of teaching. Contents of the invention [0003] The purpose of the present invention is to provide a digital voic...
