Abstract

Content presented in association with a transmitting endpoint is obtained by the transmitting endpoint and transmitted to a receiving endpoint of a videoconference, along with associated information regarding interaction of a presenter with the content at the transmitting side. The receiving endpoint presents the presented content obtained from the transmitting endpoint similar to the presentation format at the transmitting side. Where the original presentation format is not suitable for transmission, a video image of the content in the original presentation format may be transmitted. An intermediate control unit, such as a multipoint control unit, may relay content and associated information between transmitting and receiving endpoints.

Claims

1. A videoconferencing system, comprising:

a content transmitting endpoint having a content transmitting module;

a content transmitting client agent, configured for installation on a presenting conferee'"'"'s computer, the content transmitting client agent further configured for;

accessing content presented on the presenting conferee'"'"'s computer; and

transmitting to the content transmitting module the presented content in its original file format and associated information regarding activity of the presenting conferee on the presented content; and

a content receiving endpoint comprising;

a display unit;

a content receiving module, configured to receive the presented content and associated information transmitted from the content transmitting module; and

a presentation reader module configured to present on the display unit similar presented content and the activity of the presenting conferee on the presented content as it is displayed on a display unit of the presenting conferee'"'"'s computer.

2. The system of claim 1, wherein the presenting conferee'"'"'s computer is embedded in the content transmitting endpoint.

3. The system of claim 1, wherein the activity of the presenting conferee comprises marking an area of the presented content.

4. The system of claim 1, wherein the activity of the presenting conferee comprises pointing at an area of the presented content.

5. The system of claim 1, wherein the activity of the presenting conferee comprises scrolling through the content.

6. The system of claim 1, wherein the presentation reader module comprises a portable document format reader.

7. The system of claim 1, wherein the presentation reader module comprises a spreadsheet reader.

8. The system of claim 1, wherein the content transmitting client agent is configured to perform actions comprising actions that cause the content transmitting client agent to:

deliver data of a content file in its original file format toward the content transmitting module at the content transmitting endpoint;

obtain information regarding the activity of the presenting conferee on the presented content; and

deliver the obtained information toward the content transmitting module at the content transmitting endpoint.

9. The system of claim 8, wherein the content transmitting client agent at the content transmitting endpoint is configured to:

obtain presented content of a content file in its original format;

obtain associated information regarding the activity of the presenting conferee on the presented content; and

convert the obtained presented content to content in an application format, wherein the converted content, when presented by an application for viewing the application format, presents a view similar to how the content file is presented on the conferee'"'"'s computer; and

transmit, toward a content receiving endpoint, the content in the application format with the associated information.

10. The system of claim 9, wherein the application format is a portable document format.

11. The system of claim 8, wherein the content transmitting client agent comprises a transmitting application program interface that is configured to obtain the information regarding the activity of the presenting conferee on the presented content from a presentation application.

12. The system of claim 8, wherein the content transmitting client agent is configured to obtain the information regarding the activity of the presenting conferee on the presented content from information that is created by one or more human interfaces devices of the conferee'"'"'s computer.

13. The system of claim 12, wherein the one or more human interfaces devices comprises a mouse.

14. The system of claim 12, wherein the one or more human interfaces devices comprises a keyboard.

15. The system of claim 1, further comprising an intermediate control unit communicatively coupled between the content transmitting endpoint and the content receiving endpoint, comprising:

an original application content module,

wherein the presented content and associated information are transmitted from the content transmitting module toward the content receiving module via the original application content module.

16. The system of claim 15, wherein the original application content module is configured to:

receive the presented content in its original file format and the associated information from the content transmitting client agent; and

relay the presented content and associated information toward content receiving module.

17. The system of claim 15, wherein the intermediate control unit is a multipoint control unit.

18. The system of claim 17, wherein the original application content module further comprises:

a content to video converter configured to;

convert received presented content and associated information into a video image of a file view similar to a file view presented by the conferee'"'"'s computer.

19. The system of claim 18, wherein the video image of the file view is compressed and transmitted toward a second content receiving endpoint as a compressed video stream.

20. The system of claim 15, wherein the content transmitting client agent is further configured to:

obtain presented content of a content file in its original format;

obtain associated information regarding the activity of the presenting conferee on the presented content; and

convert the obtained presented content to content in an application format, such that the converted content, when it is presented by the application, presents a view similar to how the content file is presented on the conferee'"'"'s computer; and

transmit toward a third content receiving endpoint the content in the application format with the associated information.

21. The system of claim 20, wherein the application format is a portable document format.

22. A method comprising:

transmitting presented content in its original file format toward a first content receiving endpoint from a content transmitting endpoint;

obtaining associated information regarding activity of a presenting conferee on the presented content;

transmitting the associated toward the first content receiving endpoint; and

presenting the presented content and associated information by the first content receiving endpoint similar to how the presented content is presented at the content transmitting endpoint.

23. The method of claim 22, wherein the activity of the presenting conferee comprises marking an area of the content.

24. The method of claim 22, wherein the activity of the presenting conferee comprises pointing at an area of the content.

25. The method of claim 22, wherein the activity of the presenting conferee comprises scrolling the content.

26. The method of claim 22, wherein the original file format is a portable document format.

27. The method of claim 22, wherein the original file format is a spreadsheet file format.

28. The method of claim 22, wherein the associated information is obtained by a transmitting application program interface corresponding to the original file format.

29. The method of claim 22, wherein obtaining associated information comprises:

collecting information that was created by one or more human interfaces devices.

30. The method of claim 29, wherein the one or more human interfaces devices comprises a mouse.

31. The method of claim 29, wherein the one or more human interfaces devices comprises a keyboard.

32. The method of claim 22, further comprising:

converting the original file format to an application file format and the associated information regarding activity of a presenting conferee on the presented content such that the converted content, when it is presented by an application for viewing the application format at the first content receiving endpoint, presents a view similar to how the content file is presented at the content transmitting endpoint.

33. The method of claim 32, wherein the application file format is a portable document format.
