Abstract

A method and system for producing video-segments of a live-action event involving monitoring a live-action event for detection of event-segments, detecting one or more event-triggers with detectors, determining if an event-segment occurred based on the detected event-triggers, and editing one or more video feeds into a video-segment to encompass the event-segment.

Claims

1. A video-segmentation method from one or more video-feeds, comprising:

monitoring a live-action event for detection of event-segments;

detecting one or more event-triggers with detectors;

determining if an event-segment occurred based on the detected event-triggers;

editing one or more video feeds into a video-segment to encompass the event-segment.

2. The method of claim 1, wherein the monitoring step further comprises monitoring one or more video feeds for detection of event-segments.

3. The method of claim 1, further comprising the step of determining if the event-state is “

on”

or “

off”

.

4. The method of claim 3, further comprising the step of recording one or more of the one or more video-feeds if the event-state is determined to be “

on”

.

5. The method of claim 1, wherein the detectors comprise frame-by-frame pattern recognition detectors.

6. The method of claim 1, wherein the detectors comprise physical sensors.

7. The method of claim 1, wherein the detectors comprise audio recognition detectors.

8. The method of claim 1, wherein the detectors comprise scoring information detectors.

9. The method of claim 1, wherein the detectors comprise scoreboard information detectors.

10. The method of claim 1, wherein the detectors comprise external metadata detectors.

11. The method of claim 1, wherein each detected event trigger is assigned a weighted value based upon its predetermined relative weight with respect to each other detected event trigger.

12. The method of claim 13, wherein the weighted value is assigned based upon the detected event-trigger exceeding a predetermined threshold.

13. The method of claim 11, wherein the weighted value is assigned proportionally based upon the detected event-trigger exceeding a predetermined threshold.

14. The method of claim 1, wherein each detected event-trigger is assigned a weighted value based upon the predetermined relative weight of the detector that detected the event-trigger with respect to each other detector.

15. A method as claimed in claim 14, wherein the weighted value is assigned based upon a detection by one detector in the absence of a detection by one or more other detectors.

16. A method as claimed in claim 14, wherein the weighted value is assigned based upon a detection by one detector in the presence of a detection by another detector.

17. A method as claimed in claim 1, wherein each detected event-trigger is assigned a weighted value based upon a predetermined relative weight with respect to the weighted value assigned in claim 11 and the weighted value assigned in claim 14.

18. A method as claimed in claim 1, wherein information describing the event-segment is added to the video-segment.

19. A method as claimed in claim 1, wherein one or more of the video-feeds comprise a pre-edited compilation of one or more video-feeds.

20. The method of claim 1, wherein it is determined if an event-segment occurred based on an algorithm that is specific to the live action event.

21. A method as claimed in claim 20, wherein the algorithm is based upon a result of an operation, acted on one or more of weighted values, exceeding a predetermined threshold.

22. A method as claimed in claim 20, wherein the algorithm is based upon a result an operation, acted on one or more weighted values, exceeding a predetermined range of values.

23. A method as claimed in claim 20, wherein the algorithm is based upon a result of an operation, acted on one or more of weighted values, being greater than or equal to a predetermined value.

24. A method as claimed in claim 20, wherein the algorithm is based upon a result of an operation, acted on one or more of weighted values, being less than or equal to a predetermined value.

25. A method as claimed in claim 20, wherein the algorithm is based upon a result of an operation, acted on one or more of the weighted values, equaling a predetermined value.

26. A method as claimed in claim 20, wherein the algorithm is based on certain times during the live-action event corresponding to predetermined event-triggers.

27. The method of claim 1, further comprising the step of determining when an event-segment occurred based on the detected event-triggers.

28. The method of claim 27, wherein it is determined when an event-segment occurred by the recorded time of an event-trigger corresponding to a pre-selected detector.

29. The method of claim 1, wherein all event-triggers falling within a range of time within the time recorded for the event-trigger of said pre-selected detector correspond to the same event-segment.

30. The method of claim 27, wherein it is determined when an event-segment occurred by an average of the recorded times of all event-triggers falling within a range of time with respect to the recorded time of an event-trigger of a pre-selected detector.

31. The method of claim 27, wherein one or more video feeds are edited into a video-segment to encompass the event-segment based on when it is determined that the event-segment occurred.

32. The method of claim 27, wherein one or more video feeds are edited into a video-segment by beginning and ending the video-segment based on predetermined times before and after the event-segment occurred for different types of event-segments.

33. The method of claim 27, wherein only those event-triggers with equal recorded times correspond to the same event-segment.

34. A video-segment distribution method comprising:

receiving one or more video-feeds capturing a live-action event,

storing the video feeds,

performing video-segmentation to produce video-segments, and

transmitting the video-segments to devices registered for receiving the video-segments.

35. The method of claim 34, wherein the video feeds are received at substantially the same time as the live-action event is captured by the video-feeds.

36. The method of claim 34, further comprising the step of pre-encoding the video-feeds.
