Abstract

A system and method of synchronizing user agent data with video data in an optical disc player. The optical disc player includes an optical disc reader to read a user agent document, a video segment, a different user agent document, and a second video segment from a local optical disc, a user agent module to control a display of the user agent document and the different user agent document, a video playback module to control a display of the video segment and the different video segment; and an interaction application which causes a display of the user agent document with the video segment, and subsequently causes a display of the different user agent document and/or the different video segment in response to an event being generated. The event can be generated by the video playback module, the user agent module, the interaction application, or by a device external to the optical disc player.

Claims

1. A method of synchronizing user agent data with video data in an optical disc player, comprising:

displaying a user agent document with a video segment; and

displaying a different user agent document and/or a different video segment in response to an event being generated.

2. The method of claim 1, wherein said event is generated by a video playback module.

3. The method of claim 2, wherein said event relates to a video title being changed.

4. The method of claim 2, wherein said event relates to a video chapter being changed.

5. The method of claim 2, wherein said event relates to a specified time elapsed of video playback occurring.

6. The method of claim 2, wherein said event relates to a user activating a video control function.

7. The method of claim 1, wherein said event is generated by a user agent module.

8. The method of claim 7, wherein said event relates to a content being displayed in the first user agent document.

9. The method of claim 7, wherein said event relates to a user activating a link within said first user agent document.

10. The method of claim 1, wherein said event is generated by an interaction application.

11. The method of claim 10, wherein said event relates to a sub-routine being executed within said interaction application.

12. The method of claim 1, wherein said event is generated from a source external to said optical disc player.

13. The method of claim 1, wherein said event is generated from the operating system in the said optical disc player.

14. The method of claim 12, wherein said source comprises a server on a local area network and/or wide area network.

15. The method of claim 12, wherein said source comprises an external hard disc drive and/or an external optical disc drive.

16. The method of claim 1, wherein said event relates to a parameter being changed.

17. The method of claim 1, further comprising executing an event handler in response to said event which causes said displaying of said different user agent document and/or said different video segment.

18. The method of claim 17, wherein said information related to said event is used to identify said event handler.

19. The method of claim 17, wherein said event handler is identified by a predetermined name.

20. The method of claim 1, wherein said user agent document and/or said different user agent document is accessed from a local optical disc.

21. The method of claim 1, wherein said user agent document and/or said different user agent document is accessed from an external source.

22. The method of claim 1, wherein said video segment and/or said different video segment is accessed from a local optical disc.

23. The method of claim 1, wherein said video segment and/or said different video segment is accessed from an external source.

25. The optical disc player of claim 24, wherein said video playback module generates said event.

26. The optical disc player of claim 24, wherein said user agent module generates said event.

27. The optical disc player of claim 24, wherein said interaction application generates said event.

28. The optical disc player of claim 24, further comprising an external source interface, and an indication of said event is received from an external source by way of said interface.

29. The optical disc player of claim 24, further comprising a user input device, and wherein said event derives from said user input device.

24. An optical disc player, comprising:

an optical disc reader to read a user agent document, a video segment, a different user agent document, and a second video segment from a local optical disc;

a user agent module to control a display of said user agent document and said different user agent document;

a video playback module to control a display of said video segment and said different video segment; and

an interaction application which causes a display of said user agent document with said video segment, and causes a display of said different user agent document and/or said different video segment in response to an event being generated.

30. An optical disc player, comprising:

an optical disc reader to read a user agent document, a video segment, a different user agent document, and a second video segment from a local optical disc; and

a processor to cause a display of said user agent document with said video segment, and to cause a display of said different user agent document and/or said different video segment in response to an event being generated.

31. The optical disc player of claim 30, wherein said processor executes a video playback module which generates said event.

32. The optical disc player of claim 30, wherein said processor executes said user agent module which generates said event.

33. The optical disc player of claim 30, wherein said processor executes an interaction application which generates said event.

34. The optical disc player of claim 30, further comprising an external source interface, and an indication of said event is received from an external source by way of said interface.
