1. A data structure comprising:

media data; and

at least one event message associated with a particular time index of the media data, wherein the at least one event message is adapted to cause a processor including script engine to modify an in-memory representation of a graphical user interface (GUI) in which the media data is presented.

2. The data structure of claim 1, wherein the media data comprises video data.

3. The data structure of claim 1, wherein the at least one event message is further adapted to cause the script engine to determine content of the GUI by accessing the in-memory representation of the GUI.

4. The data structure of claim 3, wherein the at least one event message is further adapted to cause the script engine to access additional media content based on the content of the GUI.

5. The data structure of claim 3, wherein the at least one event message is further adapted to cause the media content to be presented in a particular order based on the content of the GUI.

6. The data structure of claim 1, wherein the GUI comprises a page displayed via a browser application.

7. The data structure of claim 1, wherein the in-memory representation of the GUI comprises a data structure stored in a memory, wherein the data structure includes a plurality of objects used to create the GUT.

8. A method comprising:

receiving, from a media engine presenting media data via a graphical user interface (GUI), a first event message associated with the media data; and

executing an instruction in response to the first event message, wherein executing the instruction causes an in-memory representation associated with the GUI in which the media data is being presented to be modified.

9. The method of claim 8, wherein the first event message is associated with a particular time index of the media data.

10. The method of claim 8, wherein modifying the in-memory representation associated with the GUI comprises changing a location in the GUI at which the media data is presented.

11. The method of claim 8, wherein modifying the in-memory representation associated with the GUI comprises loading data related to subject matter of the media data.

12. The method of claim 8, further comprising:

receiving a second event message related to the modification of the in-memory representation of the GUI; and

executing a second instruction in response to the second event message, wherein the second instruction modifies display of the media data.

13. The method of claim 12, wherein the second event message relates to subject matter of content displayed via the GUI, and wherein the display of media data is modified to relate to the subject matter.

14. A method comprising

receiving, from a media engine presenting media data via a graphical user interface (GUI), a first event message associated with the media data;

executing a first instruction in response to the first event message, wherein executing the first instruction causes content of an in-memory representation associated with the GUI to be determined; and

executing a second instruction based on the content of the in-memory representation, wherein executing the second instruction causes the presentation of the media data to be modified.

15. The method of claim 14, wherein determining the content of the in-memory representation comprises determining subject matter of one or more display elements displayed via the GUI.

16. The method of claim 15, wherein modifying the presentation of the media data comprises accessing additional media data related to the subject matter of the one or more display elements.

17. The method of claim 15, wherein modifying the presentation of the media data comprises modifying a time index associated with presentation of the media data to present a portion of the media data related to the subject matter of the one or more display elements.

18. The method of claim 15, wherein the in-memory representation associated with the GUI comprises a Document Object Model.

19. A method comprising:

receiving a first event message associated with a graphical user interface (GUI);

executing a first instruction in response to the first event message, wherein executing the first instruction causes an in-memory representation associated with the GUT to be modified; and

executing a second instruction, wherein executing the second instruction causes a presentation of media data in the GUI to be modified.

20. The method of claim 19, wherein the first event message comprises a user interaction event message.

21. The method of claim 19, wherein the first event message comprises a mouse event message.

22. The method of claim 21, wherein the mouse event message indicates a mouseover event.

23. The method of claim 19, wherein the first event message comprises a keyboard event message.

24. The method of claim 19, wherein the first event message comprises a touch screen event message.

25. The method of claim 19, further comprising executing a third instruction in response to the modification of the presentation of the media data, wherein executing the third instruction causes the in-memory representation associated with the GUT to be modified.

26. A method comprising:

presenting media data via a graphical user interface (GUI); and

sending an event message associated with a time index of the media data to a script engine, wherein the event message includes an instruction to modify an in-memory representation associated with the GUI.

27. The method of claim 26, further comprising:

receiving an instruction from the script engine to modify presentation of the media data in response to a modification of the in-memory representation associated with the GUI; and

modifying the presentation of the media data in response to the instruction.

28. The method of claim 26, further comprising receiving the media data and the event message via a plurality of data packets from a media server.

29. The method of claim 26, wherein the media data includes a Shockwave Flash object with embedded FLEX code.

30. The method of claim 29, wherein the FLEX code is adapted to send event messages to the script engine to cause particular functions to be executed.
