During the pandemic, blended learning is going from a niche to the norm, it forced educators to move online, and the classrooms need be equipped than ever to have the competence to blend the best of distance learning and face-to-face learning. This solution is to renovate traditional classrooms to fit for both of the distance teaching and local teaching. It gives your remote students real, in-class experiences; they will not miss out on those wonderful moments of spontaneous emergence that can sometimes happen in a live interactive discussion.

One of the key points of the solution is to create a system that allows online students to have the same experience as in a classroom, where teachers, online and offline students can easily interact and communicate. The second key point is not to let teachers have additional burdens, and not to require teachers to have IT technical background. Although the system equipment is very technical and complex, the teacher only needs to select the lecture mode according to the teaching method and scene.

The system consists of a PC with a touch panel monitor, multiple AV inputs like cameras, microphones, PC Monitor video/Audio, and speakers. It captures multiple camera videos/audio, microphone audios, composes professional-looking video scenes for each and every lecturing scenario, put multiple audio and video sources into a single stream for broadcast, fed to an online meeting application, and records the video for future editing and distribution. It provides an interface with the existing classroom PC in the format of a virtual webcam, so the classroom PC runs an online class with meeting platform software like Microsoft teams, Adobe Connect, Zoom, etc.
