Abstract

Systems and methods of authoring a multimedia file are described. In one method of authoring a multimedia file, a collection of media objects, including a reference media object of indexed temporally-ordered data structures, is accessed. The reference media object is rendered. While the reference media object is being rendered, a media object in the collection is linked to the reference media object with a rendering time synchronized to the rendering of the reference media object. In another multimedia file authoring method, a collection of inter-linked media objects is accessed. Media objects are sequentially rendered in accordance with a sequence of media object links selected by a user while media objects are being rendered. The sequence of selected media object links and synchronization data are stored to enable reproduction of media object rendering experienced by the user.

Claims

1. A method of authoring a multimedia file, comprising:

accessing a collection of media objects, including a reference media object of indexed temporally-ordered data structures;

rendering the reference media object; and

while the reference media object is being rendered, linking a media object in the collection to the reference media object with a rendering time synchronized to the rendering of the reference media object.

2. The method of claim 1, wherein multiple reference media objects are rendered at respective rendering timeframes, and one or more media objects in the collection are linked to respective reference media objects with respective rendering times synchronized to the rendering times of the respective linked reference media objects.

3. The method of claim 1, wherein rendering comprises sequentially displaying in a screen representations of the data structures of the reference media object.

4. The method of claim 3, further comprising displaying on the screen one or more symbols corresponding to respective media objects in the collection while the reference media object is being rendered.

5. The method of claim 4, wherein a given media object is linked to the reference media object in response to user input selecting a symbol corresponding to the given media object.

6. The method of claim 5, further comprising displaying media object symbols in a media object catalogue area of the screen and rendering the reference media object in an authoring area of the screen.

7. The method of claim 6, wherein the given media object is linked to the reference media object in response to dragging and dropping the corresponding media object symbol from the media object catalogue area to the authoring area of the screen by a user.

8. The method of claim 7, wherein the synchronized rendering time corresponds to a time when the selected media file is dropped in the authoring area of the screen.

9. The method of claim 7, wherein linking a selected media object to the reference media object further comprises storing an indication of where the selected media object is to be rendered during rendering of the reference media object based on where the selected media object is dropped by the user in the authoring area of the screen.

10. The method of claim 7, further comprising storing an indication of when rendering of the selected media file is to stop in response to user input.

11. The method of claim 10, wherein the stored stop indication corresponds to a time when the user drags the selected media object out of the authoring area of the screen.

12. The method of claim 3, further comprising rendering on the screen one or more media objects in the collection linked to the reference media object at respective times synchronized with the rendering of the reference media object.

13. The method of claim 12, wherein the reference media object and the synchronized media objects are rendered in a first window displayed on the screen, and further comprising rendering in a second window a second reference media object corresponding to one of the synchronized media objects in response to user input selecting the corresponding media object.

14. The method of claim 13, further comprising, while the second reference media object is being rendered, linking a media object in the collection to the second reference media object with a rendering time synchronized to the rendering of the second reference media object.

15. The method of claim 13, wherein the first window is closed before the second window is opened.

16. The method of claim 13, further comprising rendering in the second window one or more media objects in the collection linked to the second reference media object at respective times synchronized with the rendering of the second reference media object.

17. The method of claim 1, wherein linking a selected media object to the reference media object comprises storing a pointer to the selected media object with a start time specifying when the selected media object is to be rendered during rendering of the reference media object.

18. The method of claim 1, wherein linking a selected media object to the reference media object further comprises storing an indication of when rendering of the selected media file is to stop.

19. The method of claim 1, wherein linking a selected media object to the reference media object further comprises storing an indication of where the selected media object is to be rendered during rendering of the reference media object.

20. The method of claim 1, wherein linking a selected media object to the reference media object comprises linking the selected media object to a data structure of the reference media object.

21. The method of claim 20, wherein linking a selected media object to the reference media object comprises linking an activatable link to a particular location in the linked data structure.

22. The method of claim 1, wherein media objects comprise one or more of the following:

text, audio, graphics, still image, and full-motion video.

23. The method of claim 1, wherein the reference media object comprises a sequence of full-motion video frames.

24. A system for authoring a multimedia file, comprising a media manager operable to:

access a collection of media objects, including a reference media object of indexed temporally-ordered data structures;

render the reference media object; and

while the reference media object is being rendered, link a media object in the collection to the reference media object with a rendering time synchronized to the rendering of the reference media object.

25. A method of authoring a multimedia file, comprising:

accessing a collection of inter-linked media objects;

sequentially rendering media objects in accordance with a sequence of media object links selected by a user while media objects are being rendered; and

storing the sequence of selected media object links and synchronization data enabling reproduction of media object rendering experienced by the user.

26. The method of claim 25, wherein synchronization data includes indications of rendering duration for media objects.

27. The method of claim 25, wherein rendering media objects includes concurrently rendering with at least one reference media object one or more media objects linked to the reference media object.

28. The method of claim 26, wherein the at least one media object includes at least one reference media object of indexed temporally-ordered data structures.

29. The method of claim 27, wherein the at least one reference media object comprises a sequence of full-motion video frames.

30. The method of claim 25, wherein accessing the media object collection includes accessing multiple multimedia album page files each specifying at least one respective reference media object in the collection, at least one of the multimedia album page files containing links to one or more media objects in the collection and respective rendering times synchronized to the respective reference media object of the corresponding multimedia album page files.

31. The method of claim 25, wherein storing links includes storing links to multimedia album page files ordered in accordance with rendering times of the multimedia album page files.

32. A system for authoring a multimedia file, comprising a media manager operable to:

access a collection of inter-linked media objects;

sequentially render media objects in accordance with a sequence of media object links selected by a user while media objects are being rendered; and

store the sequence of selected media object links and synchronization data enabling reproduction of media object rendering experienced by the user.
