Abstract

Identification of segments based upon scoreboards and logos.

Claims

1. A method of processing a video comprising plurality of frames, said method comprising:

(a) identifying a slow motion replay segment of said video, where said slow motion replay segment includes at least one of said plurality of frames of said video; and

(b) identifying at least one of a starting logo transition within said video based upon said slow motion replay segment and an ending logo transition within said video based upon said slow motion replay segment; and

(c) identifying at least one replay segment of said video, apart from said slow motion replay segment, based on the identified said logo transition, and creating a summary of said video that includes said identified at least one replay segment, said summary having fewer said frames than said video.

2. The method of claim 1 further comprising identifying non-slow motion replay segments based upon said starting logo transition.

3. The method of claim 1 further comprising identifying non-slow motion replay segments based upon said ending logo transition.

4. The method of claim 1 wherein at least one of said starting logo transition and said ending logo transition are identified in the same general spatial region of a respective frame.

5. The method of claim 1 wherein said general spatial region is the central portion of said respective frame.

6. The method of claim 1 wherein said identifying of said at least one of said starting logo transition and said ending logo transition is free from user input.

7. A method of processing a video comprising plurality of frames, said method comprising:

(a) identifying a slow motion replay segment of said video, where said slow motion replay segment includes at least one of said plurality of frames of said video; and

(b) identifying at least one of a starting logo transition within said video based upon frames within 1000 frames of said replay segment and an ending logo transition within 1000 frames of said replay segment; and

(c) identifying at least one replay segment of said video, apart from said slow motion replay segment, based on the identified said logo transition, and creating a summary of said video that includes said identified at least one replay segment, said summary having fewer said frames than said video.

8. The method of claim 7 further comprising identifying non-slow motion replay segments based upon said starting logo transition.

9. The method of claim 7 further comprising identifying non-slow motion replay segments based upon said ending logo transition.

10. The method of claim 7 wherein at least one of said starting logo transition and said ending logo transition are identified in the same general spatial region of a respective frame.

11. The method of claim 7 wherein said general spatial region is the central portion of said respective frame.

12. The method of claim 7 wherein said identifying of said at least one of said starting logo transition and said ending logo transition is free from user input.
