Abstract

A system configured to playback videoconference data is provided. The system includes a media management server configured to receive videoconference data associated with a videoconference session. The media management server is configured to convert the videoconference data to a common format for storage. An event database configured to capture events occurring during the videoconference session is included. A media analysis server configured to analyze the stored videoconference data to insert indices representing the captured events is provided. A media playback unit configured to establish a connection with the media management server is included. The media playback unit is further configured to enable position control of a video stream delivered to the media playback unit from the media management server while maintaining the connection. A method, a computer readable medium, and a graphical user interface for the play back of videoconference data are also provided.

Claims

1. A graphical user interface (GUI) for playback of videoconference data rendered on a display screen, comprising:

a first region for displaying a video stream associated with the videoconference data;

a second region providing one or more document files corresponding to one or more event-based positions of the video stream;

a third region providing a media presentation, the changes of which corresponding to the event-based positions of the video stream; and

a fourth region providing a list of graphically displayed content items associated with the respective event-based positions of the video stream, wherein a selection of one of the content items triggers the first, second and third regions to present respective videoconference data corresponding to the event-based position of the video stream associated with the selected content item.

2. The GUI of claim 1, wherein the content items are associated with a configuration of the videoconference data selected from the group consisting of thumbnails, slide titles, file names and time positions corresponding to the videoconference data.

3. The GUI of claim 1, wherein the time positions correspond to indices associated with segments of the video stream.
