Abstract

Playback of multimedia data associated with a recorded conference session is simplified, particularly for a person who participated in the conference session from a mobile device. At a recording server that is in communication with a plurality of endpoints in a conference session, multimedia received from the plurality of endpoints participating in the conference session is recorded. The recording server obtains geographical location information for at least one mobile endpoint participating in the conference session as the at least one mobile endpoint moves. The recording server temporally correlates the geographical location information for the at least one endpoint with recorded multimedia data for the conference session. The recording server stores data tags for the geographical location information for the at least one mobile endpoint in association with the recorded multimedia data for subsequent use in indexing to map data to retrieve a portion of the recorded multimedia data for playback.

3. The method of claim 1, and further comprising obtaining signal quality information indicating poor reception signal quality experienced at a particular endpoint during the conference session, and wherein temporally correlating comprises temporally correlating the signal quality information with the recorded multimedia data for the conference session, and wherein storing comprises storing data tags for the signal quality information in association with the recorded multimedia data for subsequent use in retrieving a portion of the recorded multimedia data of the conference session for playback.

4. The method of claim 3, and further comprising receiving a command from a user to playback the recorded multimedia data from a point in time when the particular endpoint experienced poor signal reception quality, and in response to the command, retrieving for playback to the user a portion of the recorded multimedia data during which the particular endpoint experienced poor signal reception quality.

5. The method of claim 3, wherein obtaining signal quality information comprises obtaining information indicating poor receive signal strength information at the particular endpoint during the conference session.

6. The method of claim 1, and further comprising detecting when an endpoint joined or left the conference session, and wherein storing comprises storing a data tag in association with the recorded multimedia data indicating when a particular participant at that endpoint joined or left the conference session.

7. The method of claim 6, and further comprising receiving a command from a user to playback the recorded multimedia data relative to a point in time when the particular participant joined or left the conference session, and in response to the command, retrieving a portion of the recorded multimedia data at a point in time relative to when the particular participant joined or left the conference session.

8. The method of claim 1, and further comprising detecting a predetermined physical movement of a particular participant during the conference session using video image analysis of video data received from one or more endpoints, and wherein storing comprises storing a data tag in association with the recorded multimedia data indicating when the predetermined physical movement of the particular participant occurred during the conference session.

9. The method of claim 8, and further comprising receiving a command from a user to playback the recorded multimedia data relative to a point in time when the predetermined physical movement of the particular participant occurred, and in response to the command, retrieving a portion of the recorded multimedia data at a point in time relative to when the predetermined physical movement of the particular participant occurred.

10. The method of claim 9, wherein detecting the predetermined physical movement comprises detecting the particular participant entering or leaving a room during the conference session.

11. The method of claim 1, and further comprising monitoring signal quality information with respect to signal quality experienced at the plurality of endpoints during the conference session.

12. The method of claim 11, and further comprising generating and sending a notification to an endpoint unit where a moderator of the conference session is located, the notification indicating that one or more endpoints are experiencing poor signal quality.

13. The method of claim 11, and further comprising the recording server storing data indicating whether and when one or more endpoints are experiencing poor signal quality during the conference session, storing data marking a segment of the recorded multimedia data for the conference session as being of particular interest, and searching the stored data to determine whether any one or more or the endpoints experience poor signal quality during the segment of the recorded multimedia data.

14. The method of claim 13, and further comprising generating and sending a notification to one or more participants of the conference session that are determined to have experienced poor signal quality during the segment.

15. The method of claim 14, wherein sending the notification to the one or more participants comprises sending an email message to an email address for each of the one or more participants that are determined to have experienced poor signal quality during the segment, wherein the email message comprises a link, that when selected by a recipient of the email message, causes the recording server to automatically navigate a play-out pointer to the segment of the conference session for playback.

16. One or more computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
