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.

4. The non-transitory computer-readable memory medium of claim 1, wherein the program instructions are further executable to:

provide a request to the at least one videoconference endpoint to record the videoconference in a second recording;

wherein said receiving the second recording is performed in response to the request.

5. The non-transitory computer-readable memory medium of claim 4, wherein said providing the request to the at least one videoconference endpoint is performed based on a high quality connection from the at least one videoconference endpoint.

6. The non-transitory computer-readable memory medium of claim 1, wherein the first recording format is specified by a recording configuration.

7. The non-transitory computer-readable memory medium of claim 6, wherein the recording configuration is specified in response to user input.

8. The non-transitory computer-readable memory medium of claim 1, wherein said recording the videoconference information according to the first recording format does not require substantial modification from the received videoconference information.

9. The non-transitory computer-readable memory medium of claim 1, wherein the program instructions are further executable to:

receive a first request to view the videoconference from a first client;

receive a second request to view the videoconference from a second client;

provide the first recording to the first client in response to the first request; and

provide the second recording to the second client in response to the second request.

10. The non-transitory computer-readable memory medium of claim 9,

wherein the first request specifies the first recording format, wherein said providing the first recording is performed in response to the first request specifying the first recording format;

wherein the second request specifies the second recording format, wherein said providing the second recording is performed in response to the second request specifying the second recording format.

11. The non-transitory computer-readable memory medium of claim 1, wherein said streaming the videoconference information according to the first recording format does not require substantial modification from the received videoconference information.

12. The non-transitory computer-readable memory medium of claim 1, wherein the program instructions are further executable to:

receive a first request to view the videoconference from a first client;

receive a second request to view the videoconference from a second client;

wherein said streaming the videoconference according to the first streaming format is performed to the first client and in response to the first request;

wherein said streaming the videoconference according to the second streaming format is performed to the second client and in response to the second request.

13. A method for recording a videoconference in a plurality of formats, comprising:

receiving videoconference information of the videoconference, wherein said receiving videoconference information is performed during the videoconference, wherein the videoconference is conducted among a plurality of videoconference endpoints;

recording the videoconference information according to a first recording format of the plurality of recording formats, wherein said recording generates a first recording of the videoconference, and wherein the first recording format specifies a first resolution for the first recording;

providing a request to at least one videoconference endpoint to record the videoconference in a second recording format; and

receiving a second recording from the at least one videoconference endpoint, wherein the second recording is recorded according to the second recording format, wherein the second recording format is different than the first recording format, and wherein the second recording format specifies a second resolution for the second recording that is different than the first resolution for the first recording.

14. The method of claim 13, further comprising:

receiving a request to record the videoconference.
