Abstract

The design and implementation of a portable meeting recorder is presented. Composed of an omni-directional video camera with four-channel audio capture, the system saves a view of all the activity in a meeting and the directions from which people spoke. Subsequent analysis computes metadata that includes video activity analysis of the compressed data stream and audio processing that helps locate events that occurred during the meeting. Automatic calculation of the room in which the meeting occurred allows for efficient navigation of a collection of recorded meetings. A user interface is populated from the metadata description to allow for simple browsing and location of significant events.
