The video acquisition system is composed of several groups of full HD gimbal cameras, which are used to capture the teaching scenes such as teacher panorama, teacher close-up, student panorama and student close-up.1080P HD codec ability to achieve the teaching picture of high restore effect. At the same time, with the intelligent image analysis ability of the automatic tracking system, it can quickly locate the location behavior of teachers and students, complete the automatic tracking of teachers and students and the scene switch.
The sound collected by the microphone is processed by professional audio processor for de-noising, mixing, echo elimination, etc. Finally, all the video and audio are sent to the recording and playback host for encoding processing, generating standard MP4 files, which are saved in the recording and playback host for later editing or uploading to the platform for on-demand playback. At the same time, the audio processor built-in professional power amplifier function, directly connected to the sound box equipment can complete the classroom amplification, the deployment is more simple and convenient, the effect of high quality fidelity.
The display system displays the teacher's courseware data and supports the application of classroom teaching software through the deployment of education interactive all-in-one computer. Meanwhile, the courseware data is synchronously transmitted to the recording and broadcasting host and sent to the remote end to realize the effect of the same class in different places. The interactive all-in-one computer adopts high-precision infrared recognition technology and supports multi-touch control to restore the natural writing experience for teachers.
The control panel provides three control modes: simple control, network broadcasting and local broadcasting. It adopts simple control panel for teachers and provides "one-button" operation such as equipment on/off, recording start/stop and interactive connection, which is convenient for teachers to quickly develop teaching recording/interactive application and does not affect teachers' normal teaching process to the maximum extent.
