Abstract

A method and apparatus for producing video content. The method includes acquiring video data from a source. If the video data is not digitized, then the video data is digitized. The method includes generating scene indexes for the video data including a representative still image for each scene and combining the video data and scene indexes along with a media player on a video disc. The video player is operable to play the video data in accordance with the scene indexes including playing a scene from the video data on a client computer while displaying the representative stills for other of the scenes available for display on the video disc.

Claims

1. A method for producing a video disc comprising:

acquiring video data from a source;

if the video data is not digitized, then digitizing the video data;

generating scene indexes for the video data including a representative still image for each scene; and

combining the video data and scene indexes along with a media player on a video disc, the media player being a software application that is operable to play the video data in accordance with the scene indexes including playing a scene from the video data on a client computer while displaying the representative stills for other of the scenes available for display on the video disc.

2. The method of claim 1 wherein the step of acquiring includes capturing the video data from an analog source.

3. The method of claim 1 wherein the step of acquiring includes capturing the video data from a digital source.

4. The method of claim 1 wherein the step of generating scene indexes includes

detecting a transition between consecutive frames in the video data;

determining when the transition indicates a scene break; and

marking the end of the previous scene and a beginning of a new scene at a point in time that corresponds to the initially detected transition.

5. The method of claim 4 wherein the step of detecting a transition includes detecting a color difference between the frames.

6. The method of claim 5 where the step of detecting a transition includes determining if a difference between frames exceeds a preset threshold.

7. The method of claim 5 further comprising cropping one or more of the frames prior to detecting a color difference to eliminate effects from the boundary of the image frame.

8. The method of claim 4 wherein the step of detecting a transition includes detecting a motion difference between the frames.

9. The method of claim 8 where the step of detecting a transition includes determining if a difference between frames exceeds a preset threshold.

10. The method of claim 8 further comprising cropping one or more of the frames prior to detecting a motion difference to eliminate effects from the boundary of the image frame.

11. The method of claim 4 wherein the step of detecting a transition includes detecting a color and motion difference between the frames.

12. The method of claim 11 where the step of detecting a transition includes determining if a difference between frames exceeds a preset threshold.

13. The method of claim 11 further comprising cropping one or more of the frames prior to detecting a color and motion difference to eliminate effects from the boundary of the image frame.

14. The method of claim 4 where the step of determining when a transition indicates a scene break includes comparing plural frames to a last frame thought to be part of a preceding scene;

if for each frame a transition is detected, then determining that a scene break is indicated; and

else, determining that no scene break is indicated and continuing to search for a next scene break.

15. The method of claim 1 where the step of generating representative stills for each scene includes selecting a first frame from each scene.

16. The method of claim 1 where the step of generating representative stills for each scene includes selecting a frame from an introductory group of frames from each scene.

17. The method of claim 16 where the step of selecting a frame includes determining a color distribution for plural frames in a scene and selecting a frame from the introductory group that is a best match to the determined color distribution.

18. The method of claim 1 further comprising creating a contact sheet for distribution with the video disc that includes each representative still for the scenes detected on the video disc.

19. The method of claim 1 wherein the video disc is a compact disc.

20. The method of claim 1 wherein the video disc is a digital video disc.

21. A method for producing a video based product comprising:

acquiring video data;

generating temporal indices including analyzing the video data to detect the temporal indices, the temporal indices indicating a division of the video data into distinct segments;

providing a media player, being a software application that is operable to play the video data on a client computer in accordance with the temporal indices; and

packaging the video data, the temporal indices and media player on a physical medium for delivery to the client computer.

22. The method of claim 21 further comprising digitizing the video data prior to packaging the video data.

23. The method of claim 21 further comprising generating representative stills for one or more segments.

24. The method of claim 23 wherein the media player is operable to display one or more of the representative stills while playing the video data on the client computer.

25. The method of claim 21 further comprising generating representative stills for each segment.

26. The method of claim 21 further comprising:

providing a media editor operable to generate one or more edit lists, each edit list defining a set of operations to be performed on the video data by a second computer, so as to allow editing operations defined on a first computer to be replicated on the second computer;

editing the video data in accordance with the edit lists on the second computer; and

distributing the edited video to user designated distributees.

27. The method of claim 21 wherein the packaging step includes producing a physical manifestation of the content to be delivered.

28. The method of claim 27 wherein the physical manifestation is a video disc.

29. The method of claim 21 wherein the packaging step includes producing a streaming version of the video data in accordance with the temporal indices.

30. The method of claim 29 wherein the packaging step includes

receiving a request to webcast the streaming version of the video data;

and

streaming the streaming version to a requester.

31. The method of claim 26 where the distribution of the edited video includes providing the edit list to a central distribution site, generating the edited video at the central distribution site and directly delivering the edited video to the distributees.

32. The method of claim 26, wherein the first computer is the client computer.
