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 comprising:

acquiring video data originating from a user;

acquiring a plurality of temporal indices and a plurality of representative stills, wherein the plurality of temporal indices indicate a division of the video data into distinct segments and each of the plurality of representative stills represent a distinct segment of the video data wherein acquiring includes

evaluating the video data to detect scene transitions including processing successive frames of the video data wherein processing a frame includes identifying a representative portion of the frame including cropping the frame to identify an interior portion of the frame and exclude an exterior portion of the frame adjacent to a boundary of the frame and comparing the representative portion to a representative portion from a prior or next frame of the video data wherein comparing includes comparing a representative portion for each of the prior or next frame including comparing a cropped portion of each frame that includes an interior portion of a respective frame and excludes an exterior portion of the respective frame adjacent to a boundary of the respective frame; and

publishing the video data, the plurality of temporal indices and the plurality of representative stills.

2. The method of claim 1, where acquiring one or more temporal indices includes analyzing the video data to generate the one or more temporal indices.

3. The method of claim 1, where acquiring video data originating from a user comprises receiving video data uploaded by the user to a website.

4. The method of claim 1, where acquiring video data originating from a user comprises receiving video data provided by the user on a tangible medium.

5. The method of claim 1, further comprising:

if the video data acquired from the user is not digitized, digitizing the video data.

6. The method of claim 1 where the plurality of temporal indices and the plurality of representative stills are accessible at the distribution web site by one or more distributees designated by the user.

7. The method of claim 1, further comprising:

providing a media player at the distribution web site operable to play the video data in accordance with the plurality of temporal indices.

8. The method of claim 7, wherein the media player is further operable to play a distinct segment from the video data while displaying the plurality of representative stills for other of the distinct segments of the video data.

9. The method of claim 1, 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 first computer, so as to allow editing operations defined on a second computer to be replicated on the first computer; and

editing the video data in accordance with the edit lists on the first computer.

10. The method of claim 9, further comprising:

distributing the edited video data to the one or more distributees designated by the user.

11. The method of claim 1 wherein identifying a representative portion further comprises identifying a crop area associated with the frame and cropping the frame in accordance with the crop area, and wherein evaluating includes comparing the cropped area for a given frame with a cropped area associated with a prior or next frame.

12. The method of claim 11 wherein identifying the crop area includes determining an interior portion of a frame that excludes an exterior portion that is more likely to include camera noise artifacts.

13. The method of claim 12 wherein when the frame has dimensions of WxH, the interior portion is defined to include a rectangular portion defined by (bW, bH) -(W-bW, H-bH) where bW and bH are predefined.

14. The method of claim 13 wherein bW and bH are substantially .1xW and .1xH respectively.

15. The method of claim 1 wherein comparing the representative portions further comprises comparing a color difference, a motion difference or both.

16. The method of claim 15 wherein comparing the representative portions includes determining when the color difference and the motion difference exceed a predetermined threshold and declaring a tentative scene break at the frame.

17. The method of claim 16 wherein after declaring a tentative scene break, evaluating a next frame in the video data to determine when the color difference and motion difference still exceeds the threshold, and when so, declaring a scene break at a boundary associated with the frame.

18. The method of claim 16 wherein continuing to evaluate frames after a tentative scene break has been declared for a predetermined amount of video time, and after an expiration of the predetermined amount of video time determining if a representative portion of a current frame has a color and motion difference that is still above the predetermined threshold, and when so declaring a scene break at a boundary associated with the frame.

19. The method of claim 18 wherein when the color and motion difference does not exceed the predetermined threshold, terminating the declared scene break, not designating the frame as being associated with a scene break and continuing the evaluation of the frames of the video data to determine a next possible scene break location.

20. The method of claim 1 wherein the plurality of temporal indices and the plurality of representative stills are detected using distinct visual representations provided or identified by the user.

21. The method of claim 20 wherein acquiring further comprises searching the one or more stills or distinctive segments for one or more of characters, subjects or voices.

22. The method of claim 1 where an amount of video data is permitted to be stored at a central service and is continually accessible by the user and or others and may be transferred in via third-party protocol.
