Abstract

A videoconference may be initiated between a plurality of endpoints. At least one of the endpoints may be coupled to a recording server, which may be configured to record the videoconference. A configuration may be selected (e.g., automatically or manually) for performing the recording. The endpoint (e.g., acting as an MCU) may transmit information to endpoints and may transmit recording information to the recording server. The recording information may be different from the videoconference information. For example, it may be in a “streaming friendly” format, at a different bit rate, encoded differently, have different inputs, etc. The manner in which the videoconference is stored and/or recorded may be based on the selected configuration. Clients may be configured to receive and display the videoconference from the recording server and may be configured to change the provided layout to different layouts, e.g., based on user input.

Claims

1. A method for recording a videoconference, wherein the videoconference is conducted among a plurality of videoconference endpoints, comprising:

receiving video at a recording server, wherein the received video corresponds to the videoconference, wherein the received video is different from video provided to any of the plurality of videoconferencing endpoints in the videoconference, wherein the received video comprises a composite image, wherein the recording server stores boundaries of the composite image, and wherein the boundaries of the composite image are usable by the plurality of videoconference endpoints to change a layout of the videoconference on playback; and

recording the received video.

2. The method of claim 1, further comprising:

streaming the received video to one or more clients.

3. The method of claim 2, wherein said streaming is performed during the videoconference.

4. The method of claim 2, further comprising:

generating a transcript of the videoconference.

5. The method of claim 1, further comprising:

streaming the received video to one or more clients; and

providing a transcript of the videoconference to at least one of the one or more clients.

6. The method of claim 5, wherein the transcript of the videoconference is usable by the at least one client to:

receive user input searching for one or more words of the transcript; and

display the videoconference at a portion of the videoconference that includes a participant speaking the one or more words based on the transcript.

7. The method of claim 5, wherein the transcript is provided as a subscript on the recorded videoconference.

8. A server configured to record a videoconference, wherein the videoconference is conducted among a plurality of videoconference endpoints, wherein server comprises:

at least one network port;

at least one memory medium, storing program instructions for recording the videoconference; and

at least one processor coupled to the at least one network port and the at least one memory medium, wherein the at least one processor is configured to execute the program instructions to;

receive video at a recording server using the at least one network port, wherein the received video corresponds to the videoconference, and wherein the received video is different from video provided to any of the plurality of videoconferencing endpoints in the videoconference, wherein the received video comprises a composite image, wherein the recording server stores boundaries of the composite image, and wherein the boundaries of the composite image are usable by the plurality of videoconference endpoints to change a layout of the videoconference on playback; and

record the received video.

9. The server of claim 8, wherein the program instructions are further executable to:

stream the received video to one or more clients.

10. The server of claim 9, wherein said streaming is performed during the videoconference.

11. The server of claim 9, wherein the program instructions are further executable to:

generate a transcript of the videoconference.

12. The server of claim 9, wherein the program instructions are further executable to:

stream the received video to one or more clients; and

provide a transcript of the videoconference to at least one of the one or more clients.

13. The server of claim 12, wherein the transcript of the videoconference is usable by the at least one client to:

receive user input searching for one or more words of the transcript; and

display the videoconference at a portion of the videoconference that includes a participant speaking the one or more words based on the transcript.

14. The server of claim 12, wherein the transcript is provided as a subscript on the recorded videoconference.

15. A server configured to record a videoconference, wherein the videoconference is conducted among a plurality of videoconference endpoints, wherein server comprises:

at least one network port;

at least one memory medium, storing program instructions for recording the videoconference; and

at least one processor coupled to the at least one network port and the at least one memory medium, wherein the at least one processor is configured to execute the program instructions to;

provide respective video of the videoconference to each of the plurality of videoconferencing endpoints using the at least one network port; and

provide second video of the videoconference to a recording server using the at least one network port, wherein the second video corresponds to the videoconference, wherein the second video is different from the video provided to any of the plurality of videoconferencing endpoints, wherein the second video comprises a composite image, wherein the server stores boundaries of the composite image, and wherein the boundaries of the composite image are usable by the plurality of videoconference endpoints to change a layout of the videoconference on playback.

16. The server of claim 15, wherein the second video is configured for recording by the recording server, and provision to clients by the recording server without substantial modification.

17. The server of claim 15, wherein the respective video is different for at least two of the plurality of videoconferencing endpoints.

18. The server of claim 15, wherein the respective video is the same for all of the plurality of videoconferencing endpoints.

19. The server of claim 15, wherein the second video comprises periodic iframes, wherein the respective video does not comprise periodic iframes.

20. The server of claim 15, wherein the second video is in a streaming friendly format.

21. The server of claim 15, wherein the second video comprises a set of sources that is different from each of the respective video.

22. The server of claim 15, wherein the respective video comprises a recording indication, and wherein the second video does not comprise the recording indication.

23. The server of claim 15, wherein the program instructions are further executable to:

provide third video to the recording server, wherein the third video corresponds to the videoconference, and wherein the third video is in a different format than the second video;

wherein the third video is configured for recording by the recording server, and provision to clients by the recording server without substantial modification.
