Abstract

In a method and system for creating an extensible media player, a multimedia player application is instantiated on a client system. A presentation data file is transmitted to the client system from a server. The presentation data file includes a playlist of timelines, modules associated with each of the timelines of the playlist, and a presentation theme for each of the modules. Each module extends the functionality of the instantiated multimedia player and includes a user interface element having a reconfigurable presentation. Each presentation theme defines presentation attributes for a user interface element. A module identifies one or more multimedia files to be played or one or more applications to be executed by the multimedia player application. The presentation data file is parsed to identify the modules associated with each of the timelines of the playlist as well as a presentation theme associated with each of the modules. For a selected timeline, the modules associated with the selected timeline are loaded. Each module associated with the selected timeline is notified of the presentation theme to be applied to the module. In response to the notification, each module retrieves presentation attributes corresponding to the presentation theme and applies the presentation attributes to its user interface element.

4. The extensible media player of claim 1, wherein the presentation data file stores source identifiers to the playlist, the at least one module for each of the timelines, and the presentation theme to apply to each of the at least one module instead of the playlist, the at least one module, and the presentation theme.

5. The extensible media player of claim 4, wherein the source identifiers are URLs.

6. The extensible media player of claim 1, wherein the presentation themes are Cascading Style Sheets.

7. The extensible media player of claim 1, wherein a default presentation theme is applied to the media player application, a first presentation theme is applied to the playlist of timelines, and a second presentation theme is applied to the at least one module for the selected timeline, wherein the presentation attributes of the first presentation theme override conflicting presentation attributes of the default presentation theme, and wherein the presentation attributes of the second presentation theme override conflicting presentation attributes of the default presentation theme and the first presentation theme.

8. The extensible media player of claim 1, wherein the presentation attributes include a user interface element type, a user interface element identifier, and an element state.

9. The extensible media player of claim 1, wherein the media player application further executes the at least one loaded module in an order and a location identified by said presentation data file.

10. The extensible media player of claim 1, wherein the media player application plays the one or more media files simultaneously or executes the one or more applications simultaneously.

11. A method, comprising:

instantiating a multimedia player application on a client system;

transmitting to the client system a presentation data file from a server, the presentation data file including a playlist of timelines, modules associated with each timeline of the playlist, and a first presentation theme for each of the modules, wherein one of the modules associated with each timeline identifies one or more multimedia files to be played or one or more applications to be executed, wherein each module extends functionality of the instantiated multimedia player application and includes a user interface element having a reconfigurable presentation, and wherein the first presentation theme defines presentation attributes of the user interface element for the each module;

parsing the presentation data file to identify the modules associated with each timeline on the playlist and the presentation theme associated with each module of the modules associated with the each timeline;

for a selected timeline from the playlist of timelines, loading the modules associated with the selected timeline;

notifying each module associated with the selected timeline of the presentation theme to be applied to the each module;

retrieving, by the each module associated with the selected timeline, the presentation attributes corresponding to the presentation theme to be applied to the each module; and

applying the presentation attributes to the user interface element of the each module.

12. The method of claim 11, further comprising designating a module of the loaded modules associated with the selected multimedia file as unloadable during a lifetime of the instantiated multimedia player.

13. The method of claim 11, further comprising when a module of the loaded modules associated with the selected multimedia file raises an event, logging the event in an event manager, said logging comprising recording an identifier of the module raising the event, an event type, a time of occurrence of the event, and any data transmitted during the event.

14. The method of claim 11, further comprising, replacing the playlist, the modules, and the presentation theme for the each of the modules with source identifiers to the playlist, the modules, and the presentation theme for the each of the modules.

15. The method of claim 11, wherein the source identifiers are URLs.

16. The method of claim 11, wherein the presentation theme is a Cascading Style Sheet.

17. The method of claim 11, further comprising:

applying a default presentation theme to the instantiated multimedia player application;

applying a second presentation theme to the playlist of timelines; and

applying the first presentation theme to the each module associated with selected timeline,

wherein the presentation attributes of the second presentation theme override conflicting presentation attributes of the default presentation theme, and

wherein the presentation attributes of the first presentation theme override conflicting presentation attributes of the default presentation theme and the second presentation theme.

18. The method of claim 11, wherein the presentation attributes include a user interface element type, a user interface element identifier, and an element state.

19. The method of claim 11, further comprising executing the at least one loaded module in an order and a location identified by said presentation data file.

20. The method of claim 11, wherein the one or more multimedia files are played simultaneously and the one or more applications are executed simultaneously.
