Abstract

A cue point data structure is maintained independent of a recorded time-varying content file. Embodiments of the present invention enable cue point data structures to be defined and then saved and independently recalled for application to any recorded time-varying content file. An authoring tool includes an interface to enable an author to, once having defined one or more cue points for a first recorded time-varying content file, save data structure(s) defining such one or more cue points independent of the first recorded time-varying content file. The authoring tool may further include an interface that enables an author to recall previously-saved cue point data structures. In this manner, the author may save and reuse cue point data structures. Further, a plurality of cue points may be saved together as a cue point scenario. Additionally, the data structure may be in a non-proprietary format, such as an extensible mark-up language (XML) format.

Claims

1. A method comprising:

receiving, by a processor, information defining at least one cue point for a recorded time-varying content file;

forming, by the processor, a data structure containing the received information;

storing, by the processor, the data structure to data storage such that the data structure is accessible independent of the recorded time-varying content file; and

using the data structure for inserting the at least one cue point into a second recorded time-varying content file.

2. The method of claim 1 wherein the recorded time-varying content file comprises at least one of audio, video, audiovisual, animation, and multimedia content types.

3. The method of claim 1 wherein said receiving, forming, and storing are performed by an authoring tool.

4. The method of claim 1 wherein the at least one cue point comprises a plurality of cue points that form a cue point scenario for the recorded time-varying content file.

5. The method of claim 4 wherein said storing comprises:

storing the cue point scenario to said data storage such that the cue point scenario is accessible independent of the recorded time-varying content file.

6. The method of claim 1 wherein said receiving comprises:

receiving one or more of a name for the at least one cue point, a corresponding time in the recorded time-varying content at which the at least one cue point resides, a type of the at least one cue point, and one or more parameters for the at least one cue point.

7. The method of claim 1 further comprising:

reusing the data structure for inserting said at least one cue point into at least a second recorded time-varying content file.

8. The method of claim 1 wherein the data structure is stored in a non-proprietary format comprising extensible mark-up language (XML) format.

9. The method set forth in claim 1, wherein the data structure is a cue point exchange data structure comprising a plurality of cue point elements, each cue point element comprising a time element and at least one parameter element.

10. A method of claim 1 further comprising embedding, by the processor, a cue point flag in the recorded time-varying content file, wherein the cue point flag references the data structure.

11. The method of claim 10 wherein a cue point name and corresponding time identifier are embedded as the cue point flag in the recorded time-varying content file.

12. The method of claim 1 where in the data structure comprises a cue point parameter for an action triggered by the cue point.

13. A non-transitory computer readable storage medium comprising computer-executable software code, which when executed by a computer provides an authoring tool with which a user can interact to author a recorded time-varying content file, and when executed by the computer the software code causes the computer to perform a method comprising:

receiving information defining at least one cue point for a recorded time-varying content file;

forming an extensible mark-up language (XML) formatted data structure containing the received information;

storing the data structure to data storage such that the data structure is accessible independent of the recorded time-varying content file; and

using the data structure for inserting the at least one cue point into a second recorded time-varying content file.

14. The non-transitory computer readable storage medium of claim 13 wherein the recorded time-varying content file comprises at least one of audio, video, audiovisual, animation, and multimedia content types.

15. The non-transitory computer readable storage medium of claim 13 wherein the at least one cue point comprises a plurality of cue points that form a cue point scenario for the recorded time-varying content file.

16. The non-transitory computer readable storage medium of claim 15 wherein said storing comprises:

storing the cue point scenario to said data storage such that the cue point scenario is accessible independent of the recorded time-varying content file.

17. The non-transitory computer readable storage medium of claim 13 wherein said receiving comprises:

receiving one or more of a name for the at least one cue point, a corresponding time in the recorded time-varying content at which the at least one cue point resides, a type of the at least one cue point, and one or more parameters for the at least one cue point.

18. The non-transitory computer readable storage medium of claim 13 wherein when executed by the computer the software code causes the computer to further perform:

presenting a user interface for triggering said storing of the data structure.

19. The non-transitory computer readable storage medium of claim 13 wherein when executed by the computer the software code causes the computer to further perform:

presenting a user interface for opening a previously-stored data structure that contains information defining at least one cue point.

20. The non-transitory computer readable storage medium of claim 13 wherein when executed by the computer the software code causes the computer to further perform:

enabling reuse of the data structure for inserting said at least one cue point into at least a second recorded time-varying content file.

21. The code set forth in claim 13, wherein the data structure is a cue point exchange data structure comprising a plurality of cue point elements, each cue point element comprising a time element and at least one parameter element.

22. A method comprising:

receiving, by an authoring tool, information defining a cue point scenario that contains a plurality of cue points for a recorded time-varying content file;

forming a data structure containing the received information, the data structure formed in a non-proprietary data format; and

storing the data structure to data storage such that the data structure is accessible independent of the recorded time-varying content file; and

using the data structure for inserting said plurality of cue points into a second recorded time-varying content file.

23. The method of claim 22 wherein the non-proprietary format comprises extensible mark-up language (XML) format.

24. The method of claim 22 wherein the recorded time-varying content file comprises at least one of audio, video, audiovisual, animation, and multimedia content types.

25. The method of claim 22 wherein said receiving, forming, and storing are performed by an authoring tool.

26. The method of claim 22 further comprising:

reusing the data structure for inserting said plurality of cue points into at least a second recorded time-varying content file.

27. The method set forth in claim 22,

wherein the data structure is a cue point exchange data structure comprising a plurality of cue point elements, each cue point element corresponding to a respective one of the plurality of cue points of the cue point scenario, and
