Classroom Recording & Broadcasting System

The Classroom Recording & Broadcasting System supports multi-point simultaneous recording, enabling synchronized recording and live streaming of teacher video, student video, audio, and dynamic computer screen content within the classroom. It comprehensively captures the teaching process and instantly generates multimedia teaching courseware. With high picture quality, it can be used for teaching analysis and preserved as school resources.

Multi-camera positioning captures the classroom teaching status, with automatic camera switching based on student speaking status, and automatic switching to a panoramic view when no one is speaking.

It is expected to simultaneously transmit three video streams — teacher video (including blackboard writing video), student video, and lecture handouts — as well as interactive terminal video.

Supports automatic tracking of the teacher's face and body using cameras and directional microphones.

Lecture handouts can include multiple signal modes such as physical projection video, handout computer video, and touchscreen computer video, with intelligent automatic switching.

Simultaneously supports synchronized display of classroom archives, student archives, and course plan databases.

Supports synchronized display of supervision and student interaction information.

Supports online or offline integrated video director-switching composition, generating high-quality streams for live broadcasting and on-demand playback.

Supports multi-window synchronized recording and synchronized playback, with the ability to enlarge any window during playback.

Live broadcasting and post-production on-demand use a single video stream, saving transmission bandwidth.

Supports automatic director-switching under defined rules to generate a composite video stream.
