A typical lecture capture system consists of three main components: capture hardware, processing software, and distribution platforms.

The capture layer includes cameras, microphones, and input interfaces that collect video and audio signals from the classroom. These inputs may include HDMI or SDI video from presentation devices, as well as ceiling or lapel microphones for clear speech recording.

The processing layer encodes and synchronizes the captured signals. Advanced systems automatically detect presentation changes, switch camera angles, and apply video layouts. Hardware-based lecture capture solutions often provide higher reliability and lower latency compared to purely software-based systems.

Finally, the distribution layer delivers recorded or live-streamed content to students via LMS platforms, media servers, or cloud-based portals. This architecture allows institutions to scale lecture capture across multiple classrooms with centralized management.
