Composition of the teaching recording system

A teaching recording and broadcasting system is a device system used to record classroom teaching activities. It can achieve functions such as synchronous recording, editing, storage, and on-demand playback of audio and video. A typical teaching recording and broadcasting system usually consists of the following main components:

Audio-Visual Signal Acquisition System:

Cameras: This includes teacher cameras, student cameras, and blackboard cameras. Teacher cameras and student cameras usually adopt fast spherical cameras with rotating pan-tilts to track and shoot targets. Blackboard cameras should be able to clearly capture the text and graphics on the blackboard.

Audio Pickup Devices: Composed of teacher audio pickup microphones and student audio pickup microphones, they are used to collect and record high-quality audio signals from the classroom scene.

Camera Tracking and Positioning System:

This system is used to intelligently track the positions of teachers and students and automatically switch videos according to the teaching process. Common tracking control methods include infrared control, image recognition control, ultrasonic control, and voice recognition control.

Recording and Broadcasting Control System:

Recording and Broadcasting Software: Used to complete courseware recording in single-screen, picture-in-picture, and multi-screen modes, and automatically generate introductions and endings.

Recording and Broadcasting Console: The device can automatically or manually control the collaborative work of devices, control the switching, use, and parameter adjustment of devices, and intuitively obtain results through display and indication functions.

Intelligent Switching Control System: Capable of intelligent editing and automatic editing, providing multiple sets of input and output interfaces, automatic camera switching, and real-time recording and broadcasting.

Video Processing System:

Responsible for editing, splicing, adding subtitles, etc., to the recorded videos, making the course videos more perfect.

Online Platform:

Used to store and publish recorded course videos, facilitating teachers and students to access and on-demand review anytime and anywhere.
