Claims
- 1. A computer-based method of synchronizing a realization of a media stream having a first representation synchronized with said realization, and at least one second representation, said method comprising:
determining structure information for said first representation and said at least one second representation; determining structure association information between said first representation and said at least one second representation; and synchronizing said at least one second representation with said first synchronized representation and said realization using said structure association information.
- 2. The method according to claim 1, said step of determining structure information further comprising:
analyzing said structure information of said first and said at least one second representation, and providing a stream of tree locators.
- 3. The method according to claim 2, further comprising:
aligning said determined structure information of said first representation and said at least one second representation.
- 4. The method according to claim 3, wherein said realization comprises at least one version of content, said method further comprising:
aligning said at least one version of content with said first representation to produce a web of relations between said at least one version of content and said first representation.
- 5. The method according to claim 4, wherein said aligning said at least one version of content with said first representation produces a web of relations between a structural view of said at least one version of content and said first representation.
- 6. The method according to claim 3, further comprising:
aligning an audio stream specified by said media stream with an audio structure corresponding to said audio stream.
- 7. The method according to claim 3, further comprising:
aligning a text stream specified by said media stream with a text structure corresponding to said text stream.
- 8. A system for synchronizing a realization of a media stream having a first representation synchronized with said realization, and at least one second representation, said method comprising:
a first structurer configured to determine structure information for said first representation; at least a second structurer configured to determine structure information for said at least one second representation; and a first aligner configured to align said structure information for said first representation and said at least one second representation.
- 9. The system according to claim 8, further comprising:
at least one renderer configured to render said at least one second representation, after being synchronized, in a form suitable for displaying as an overlayed subtitle.
- 10. The system according to claim 9, wherein said realization specifies a media stream, said system further comprising:
a tree aligner configured to determine a tree structure for said media stream.
- 11. The system according to claim 10, further comprising:
means for detecting speech and non-speech boundaries.
- 12. The system according to claim 10, further comprising:
means for detecting transitions and speaker changes.
- 13. A machine-readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:
determining structure information for a first representation being synchronized to a corresponding media stream and at least one second representation; determining structure association information between said first representation and said at least one second representation; and synchronizing said at least one second representation with said first synchronized representation and said realization using said structure association information.
- 14. The machine-readable storage according to claim 13, said step of determining structure information further comprising:
analyzing said structure information of said first and said at least one second representation, and providing a stream of tree locators.
- 15. The machine-readable storage according to claim 14, further comprising:
aligning said determined structure information of said first representation and said at least one second representation.
- 16. The machine-readable storage according to claim 15, wherein said realization comprises at least one version of content, said machine-readable storage further comprising:
aligning said at least one version of content with said first representation to produce a web of relations between said at least one version of content and said first representation.
- 17. The machine-readable storage according to claim 15, wherein said aligning said at least one version of content with said first representation produces a web of relations between a structural view of said at least one version of content and said first representation.
- 18. The machine-readable storage according to claim 15, further comprising:
aligning an audio stream specified by said media stream with an audio structure corresponding to said audio stream.
- 19. The machine-readable storage according to claim 15, further comprising:
aligning a text stream specified by said media stream with a text structure corresponding to said text stream.
