Abstract

A method is provided in one example embodiment and includes establishing a video session in which a plurality of displays are used for rendering video data, and evaluating a presentation element in order to identify a control element that includes control data. The control element is included in the presentation element. The method further includes communicating at least a portion of the control data such that it can be used to determine which video data is to be rendered on the plurality of displays.

Claims

1. A method, comprising:

establishing a video session in which a plurality of displays are used for rendering video data;

evaluating a presentation element to identify a control element that includes control data, wherein the control element is included in the presentation element, and the presentation element is a selected one of a group of presentation elements, the group consisting of;

a word processor document, a PDF document, a slide presentation, and an e-mail; and

communicating at least a portion of the control data such that the portion of the control data can be used to determine which video data is to be rendered on the plurality of displays.

2. The method of claim 1, wherein the control data provides a switching command that relates to rendering particular image data on a particular one of the displays.

3. The method of claim 1, wherein the control element provides a change in a switching mode such that subsequent control elements included in the presentation element control which of the video data is to be rendered on the displays.

4. The method of claim 1, wherein the control element is communicated to a multipoint network element configured to exchange data in the video session.

5. The method of claim 4, wherein the control element is decrypted and reformatted before being communicated to the multipoint network element.

6. The method of claim 1, wherein contact information is accessed to retrieve information associated with image data to be rendered on at least one of the displays.

7. The method of claim 1, wherein the word processor document is a Word document;

the slide presentation is a PowerPoint document; and

the method further comprises;

identifying a control element including control data by evaluating one of a group consisting of;

a media object;

a video object;

an audio object; and

a graphic.

8. Logic encoded in non-transitory media that includes code for execution and, when executed by a processor, operable to perform operations comprising:

establishing a video session in which a plurality of displays are used for rendering video data;

evaluating a presentation element to identify a control element that includes control data, wherein the control element is included in the presentation element, and the presentation element is a selected one of a group of presentation elements, the group consisting of;

a word processor document, a PDF document, a slide presentation, and an e-mail; and

communicating at least a portion of the control data such that the portion of the control data can be used to determine which video data is to be rendered on the plurality of displays.

9. The logic of claim 8, wherein the control data provides a switching command that relates to rendering particular image data on a particular one of the displays.

10. The logic of claim 8, wherein contact information is accessed to retrieve information associated with image data that is to be rendered on at least one of the displays.

11. The logic of claim 8, wherein the control element provides a change in a switching mode such that subsequent control elements included in the presentation element control which of the video data is to be rendered on the displays.

12. The logic of claim 8, wherein the control element is communicated to a multipoint network element configured to exchange data in the video session.

13. The logic of claim 12, wherein the control element is decrypted and reformatted before being communicated to the multipoint network element.

14. An apparatus, comprising:

a memory element configured to store data;

a command decoder module; and

a processor operable to execute instructions associated with the data, wherein the processor, the command decoder module, and the memory element cooperate to;

establish a video session in which a plurality of displays are used for rendering video data;

evaluate a presentation element to identify a control element that includes control data, wherein the control element is included in the presentation element, and the presentation element is a selected one of a group of presentation elements, the group consisting of;

a word processor document, a PDF document, a slide presentation, and an e-mail; and

communicate at least a portion of the control data such that the portion of the control data can be used to determine which video data is to be rendered on the plurality of displays.

15. The apparatus of claim 14, wherein the control data provides a switching command that relates to rendering particular image data on a particular one of the displays.

16. The apparatus of claim 14, wherein the control element provides a change in a switching mode such that subsequent control elements included in the presentation element control which of the video data is to be rendered on the displays.

17. The apparatus of claim 14, wherein the control element is communicated to a multipoint network element configured to exchange data in the video session.

18. The apparatus of claim 17, wherein the control element is decrypted and reformatted before being communicated to the multipoint network element.

19. The apparatus of claim 14, wherein contact information is accessed to retrieve information associated with image data to be rendered on at least one of the displays.

20. The apparatus of claim 14, wherein the word processor document is a Word document;

the slide presentation is a PowerPoint document; and

the processor is configured to identify a control element including control data by evaluating one of a group consisting of;

a media object;

a video object;

an audio object; and

a graphic.
