Abstract

A collaborative annotation system for facilitating annotations, such as commentaries, of time-based media, such as video, by users is disclosed. The system involves displaying and controlling the display of a time-based medium, and receiving and storing input for defining a location in the time-based medium. The system also involves receiving and storing an annotation relating to the context of the location, and performing and storing a valuation relating to the annotation.

Claims

1. A system for generating meta-data by means of user annotations relating to a time-based media, comprising:

means for displaying and controlling the display of a time-based medium;

means for receiving and storing input for defining a location in the time-based medium;

means for receiving and storing an annotation relating to the context of the location in the time-based medium; and

means for performing and storing a valuation relating to the annotation.

2. The system as in claim 1, wherein the valuation relating to the annotation is a rating of the annotation.

3. The system as in claim 2, wherein the means for storing the annotation includes means for linking the stored annotation to the time-based medium.

4. The system as in claim 2, further comprising means for facilitating collaborative annotation by a plurality of users in a first group.

5. The system as in claim 4, wherein the means for facilitating collaborative annotation includes means for receiving and storing annotations from a plurality of users in the first group relating to the contexts of a plurality of locations.

6. The system as in claim 5, wherein the means for facilitating collaborative annotation further includes means for receiving ratings relating to the annotations from a plurality of users in the group.

7. The system as in claim 6, wherein the means for facilitating collaborative annotation further includes means for aggregating the annotations.

8. The system as in claim 7, wherein the means for facilitating collaborative annotation further includes means for selecting an annotation from the annotations based on the rating relating to the selected annotation.

9. The system as in claim 8, wherein the means for selecting the annotation includes means for selecting the annotation based on a rating threshold.

10. The system as in claim 8, wherein the means for facilitating collaborative annotation further includes means for receiving annotations from a plurality of users in a second group relating to the contexts of a plurality of locations in the time-based medium and the selected annotation relating to a first group.

11. The system as in claim 10, wherein the means for facilitating collaborative annotation further includes means for receiving ratings from a plurality of users in the second group relating to the annotations relating to the second group and the selected annotation relating to the first group.

12. The system as in claim 11, wherein the means for facilitating collaborative annotation further includes means for aggregating the annotations relating to the second group and the selected annotation relating to the first group.

13. The system as in claim 12, wherein the means for facilitating collaborative annotation further includes means for selecting an annotation from the annotations relating to the second group and the selected annotation relating to the first group based on the rating relating to the selected annotation.

14. The system as in claim 13, wherein the means for facilitating collaborative annotation further includes means for consolidating the annotations relating to the second group and the selected annotation relating to the first group when annotations and ratings are provided by a predetermined number of groups.

15. The system as in claim 14, further comprising means for indexing the plurality of locations in the time-based medium with corresponding consolidated annotations.

16. The system as in claim 14, further comprising means for linking the plurality of locations in the time-based medium with corresponding aggregated annotations.

17. The system as in claim 16, further comprising means for storing the consolidated and aggregated annotations.

18. The system as in claim 17, further comprising means for bundling the time-based media, the consolidated annotations, and the links between the time-based medium and the corresponding aggregated annotations.

19. The system as in claim 18, wherein the means for bundling further bundles machine derived meta-data with the time-based media, the consolidated annotations, and the links between the time-based medium and the corresponding aggregated annotations.

20. The system as in claim 18, further comprising means for displaying the consolidated annotations.

21. The system as in claim 18, further comprising means for providing as output the consolidated annotations.

22. A method for generating meta-data by means of user annotations relating to a time-based media, comprising the steps of:

displaying and controlling the display of a time-based medium;

receiving and storing input for defining a location in the time-based medium;

receiving and storing an annotation relating to the context of the location in the time-based medium; and

performing and storing a valuation relating to the annotation.

23. The method as in claim 22, wherein the step of performing and storing the valuation includes the step of performing and storing a rating of the annotation.

24. The method as in claim 23, wherein the step of storing the annotation includes the step of linking the stored annotation to the time-based medium.

25. The method as in claim 22, further comprising the step of facilitating collaborative annotation by a plurality of users in a first group.

26. The method as in claim 25, wherein the step of facilitating collaborative annotation includes the step of receiving annotations from a plurality of users in the group relating to the contexts of a plurality of locations.

27. The method as in claim 26, wherein the step of facilitating collaborative annotation further includes the step of receiving ratings relating to the annotations from a plurality of users in the first group.

28. The method as in claim 27, wherein the step of facilitating collaborative annotation further includes the step of aggregating the annotations.

29. The method as in claim 28, wherein the step of facilitating collaborative annotation further includes the step of selecting an annotation from the annotations based on the rating relating to the selected annotation.

30. The method as in claim 29, wherein the step of selecting the annotation includes the step of selecting the annotation based on a rating threshold.

31. The method as in claim 29, wherein the step of facilitating collaborative annotation further includes the step of receiving annotations from a plurality of users in a second group relating to the contexts of a plurality of locations in the time-based medium and the selected annotation relating to a first group.

32. The method as in claim 31, wherein the step of facilitating collaborative annotation further includes the step of receiving ratings from a plurality of users in the second group relating to the annotations relating to the second group and the selected annotation relating to the first group.

33. The method as in claim 32, wherein the step of facilitating collaborative annotation further includes the step of aggregating the annotations relating to the second group and the selected annotation relating to the first group.

34. The method as in claim 33, wherein the step of facilitating collaborative annotation further includes the step of selecting an annotation from the annotations relating to the second group and the selected annotation relating to the first group based on the rating relating to the selected annotation.

35. The method as in claim 34, wherein the step of facilitating collaborative annotation further includes the step of consolidating the annotations relating to the second group and the selected annotation relating to the first group when annotations and ratings are provided by a predetermined number of groups.
