Abstract

Techniques are provided for converting live presentations into electronic media and managing captured media assets for distribution. An exemplary system includes capture devices that capture media assets of live presentations comprising a session, including image data of sequentially presented visual aids accompanying the live presentations and audio data. Each capture device has an interface for real-time image data marking of the image data for identification of individual images and session marking of the image data for demarcation of individual presentations of the session. A centralized device processes the captured media assets and automatically divides the captured media assets into discrete files associated with the individual presentations based on the session markings. An administrative tool manages the processed media assets to produce modified presentations and enables modification of the visual aid images identified by the image data markings. A production device formats the modified presentations for distribution on distribution media.

Claims

1. A method of capturing a live presentation, comprising:

capturing image data from images from a display device which displays said images from projected media for viewing by an audience during a live presentation;

during the live presentation, detecting the change over from one image of a projected media to another image of the projected media;

recording the audio portion of a speaker'"'"'s presentation during a live presentation; and

in response to said detected change over from the one image to another, automatically synchronizing change over from the one image to another with the audio recording.

2. The method of claim 1, wherein the captured image data is video image data.

3. The method of claim 2, wherein the video image data is captured by a video imaging element.

4. The method of claim 3, wherein the video imaging element is a digital video image capture board.

5. The method of claim 2, wherein the changeover of the video image data is detected by an automatic sensing algorithm.

6. The method of claim of 1, further comprising:

sending the captured images and recorded audio portion of a presentation to a client.

7. The method of claim 1, further comprising:

determining a location of an input device pointer on the display device; and

associating a time stamp with the determined location.

8. The method of claim 7, further comprising:

synchronizing the captured images with locations of the input device pointer on the display device.

9. The method of claim 1, wherein the images of the projected media include image data of sequentially presented visual aids.

10. The method of claim 9, wherein the sequentially presented visual aids include at least one of slides, photographs, graphs, discrete motion picture clips, and text.

11. The method of claim 1, wherein the images of the projected media are video images captured by a capture device.

12. The method of claim 11, wherein the video images are captured at a frame rate of 12-15 frames per second.

13. The method of claim 1, further comprising:

capturing video images of a presenter during the live presentation.

14. A system for capturing a live presentation, the system comprising:

a least one capturing device configured to capture image data from images from a display device which displays said images from projected media for viewing by an audience during a live presentation;

a detector configured to detect, during the live presentation, the change over from one image of a projected media to another image of the projected media;

a recorder configured to record the audio portion of a speaker'"'"'s presentation during a live presentation; and

a synchronizer configured to automatically synchronize change over from the one image to another with the audio recording, in response to said detected change over from the one image to another.

15. The system of claim 14, wherein the captured image data is video image data.

16. The system of claim 15, wherein the video image data is captured by a video imaging element.

17. The system of claim 16, wherein the video imaging element is a digital video image capture board.

18. The system of claim 15, wherein the changeover of the video image data is detected by an automatic sensing algorithm.

19. The system of claim 14, further comprising:

a sending unit configured to send the captured images and recorded audio portion of a presentation to a client.

20. The system of claim 14, further comprising:

a tracking device configured to determine a location of an input device pointer on the display device,

wherein a time stamp is associated with the determined location.

21. The method of claim 20, wherein the captured images are synchronized with locations of the input device pointer on the display device.

22. The system of claim 14, wherein the images of the projected media include image data of sequentially presented visual aids.

23. The system of claim 22, wherein the sequentially presented visual aids include at least one of slides, photographs, graphs, discrete motion picture clips, and text.

24. The system of claim 14, wherein the images of the projected media are video images captured by a capture device.

25. The system of claim 24, wherein the video images are captured at a frame rate of 12-15 frames per second.

26. The system of claim 14, further comprising:

a capturing device configured to capture video images of a presenter during the live presentation.
