Abstract

The present invention provides an apparatus and method for automatically generating moving picture highlights for video stored in a digital video recorderthat detects scene change of stored video, extracts information amount with respect to the relevant video interval on the basis of tile scene change detection information, automatically generates moving picture highlights according to moving picture highlight length information set by a user or default value in the system, on the basis of results of the scene change detection and the interval information amount.

Claims

1-20. -20. (canceled)

21. A method for generating a highlight from video data, the method comprising:

detecting at least a first scene and a second scene in video data,

wherein a first image is associated with the first scene and a second image is associated with the second scene; and

generating a highlight for at least the first scene by selecting a plurality of images from said first scene based on interval data and user input.

22. The method of claim 21, wherein at least one of the first scene and the second scene is a primary scene.

23. The method of claim 22, wherein the highlight is recorded in a storage medium.

24. The method of claim 21, wherein the video data comprises video data recorded on a storage medium.

25. The method of claim 21, wherein the video data comprises streaming video.

26. The method of claim 21, wherein the highlight for at least the first scene is generated in response to user input.

27. The method of claim 26, wherein the highlight for the first scene is generated exclusive of a highlight for the second scene.

28. The method of claim 27, wherein the interval data and the user input are provided to indicate a preferred length for duration of the highlight.

29. The method of claim 21, wherein the first scene and the second scene are detected by detecting scene change points in the video data.

30. The method of claim 29, wherein the scene change points are detected based on differences between DC images of I-pictures for the plurality of images.

31. A system for generating a highlight from video data, the system comprising:

a scene detector for detecting at least a first scene and a second scene in video data,

wherein a first image is associated with the first scene and a second image is associated with the second scene,; and

a highlight generator for generating a highlight for at least the first scene by selecting a plurality of images from said first scene based on interval data and user input.

32. The system of claim 31, wherein at least one of the first scene and the second scene is a primary scene.

33. The system of claim 32, wherein the highlight is recorded in a storage medium.

34. The system of claim 31, wherein the video data comprises video data recorded on a storage medium.

35. The system of claim 31, wherein the video data comprises streaming video.

39. The system of claim 31, wherein the first scene and the second scene are detected by detecting scene change points in the video data.

40. The system of claim 39, wherein scene change points are detected based on differences between DC images of I-pictures for the plurality of images.
