Abstract

A system for capturing and controlling access to concurrently recorded timestreams of a session. A session is of a collaborative activity such as a meeting. Timestreams of the session are captured by various recording devices. The timestreams are analyzed to create a set of events for each timestream. An event is subsequently used as an index for replaying the session. Playback of the timestreams is done in order to recall dialogs or other events that occurred during the meeting. The timestreams are played back contemporaneously. A timeline interface having the events mapped thereon is used to traverse through the different portions of the session.
