Abstract
Media input streams are retrieved by a notetaking device and referenced for playback. The media streams are from microphones, video cameras, and media players present during a notetaking session. Facilities provided by the notetaking device allow a user to capture stills from the media streams, make annotations, and reference important events that occur during a notetaking session. Thumbnails, snaps, and backgrounds may be created from the input media streams and are used to reference into the media streams which are stored for later playback. A channel changer allows a user to switch between the various media streams during either notetaking or playback. A timeline is automatically generated that references important events, including slide changes, presented during a notetaking session.
