Abstract

A system for generating a structured file that includes all of the various media items need to play the corresponding media presentation is described. (Media items include, for example, images, movies, and audio files.) In one implementation, all of the various media items needed to support the presentation'"'"'s playback may be collected, where after at least one of them is texturized. Texturing means converting a media item from a larger format to a smaller format. For example, a JPEG file (described in terms of scalable vector-based data) may be texturized to a PNG file (described in terms of pixel data). The items may then be organized in accordance with an event, and stored in a structured file. Once organized by event (e.g., presentation pause-points, frame transitions, effect transitions, input “click” and the like), the media items may be stored into the structured file, ready to playback the media presentation.

Claims

1. A computer-implemented method, comprising:

creating, in a memory, a structured file for storing first and second portions of data related to a media presentation, wherein each portion of data comprises one or more media items;

accessing the first and second portions of data related to the media presentation;

organizing the data related to the media presentation according to an event;

converting each of the one or more media items in the first portion of data from an original type to a converted type to generate a third portion of data comprising each of the one or more converted media items; and

exporting the second and third portions of data to the structured file in accordance with the organized data related to the media presentation,

wherein the structured file comprises tags for mapping between an identity of exported media items and use of those media items in the media presentation.

2. The method of claim 1, wherein converting comprises converting an image having a first format to an image having a second format.

3. The method of claim 1, wherein the media presentation comprises a plurality of scenes, and the tags further comprise a time-ordered list of the plurality of scenes.

4. The method of claim 3, wherein the time-ordered list of the plurality of scenes further comprises an initial state of a media item that corresponds to a beginning of the media presentation.

5. A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

create, in a memory, a structured file for storing first and second portions of data related to a media presentation, wherein each portion of data comprises one or more media items;

access the first and second portions of data related to the media presentation;

organize the data related to the media presentation according to an event;

convert each of the one or more media items in the first portion of data from an original type to a converted type to generate a third portion of data comprising each of the one or more converted media items; and

export the second and third portions of data to the structured file in accordance with the organized data related to the media presentation,

wherein the structured file comprises tags for mapping between an identity of exported media items and use of those media items in the media presentation.

6. The non-transitory program storage device of claim 5, wherein the instructions to cause the one or more processors to convert comprise instructions to cause the one or more processors to convert an image having a first format to an image having a second format, wherein the first and second formats are different.

7. The method of claim 5, wherein the media presentation comprises a plurality of scenes, and the tags further comprise a time-ordered list of the plurality of scenes.

8. The non-transitory program storage device of claim 7, wherein the time-ordered list of the plurality of scenes further comprises an initial state of a media item that corresponds to a beginning of the media presentation.

9. A computer-implemented method, comprising:

accessing a structured file containing all media items related to a media presentation, wherein at least one of the media items comprises a textured media item;

reading, by an interpreter of a playback device, tags associated with the media items related to the media presentation, wherein the tags are for mapping between each of one or more of the media items and for use of each of the one or more media items during playback of the media presentation; and

playing, by the playback device, a time-ordered sequence of media items related to the media presentation in accordance with the structured file,

wherein playing includes presenting the at least one textured media item in accordance with a characteristic of the playback device.

10. The method of claim 9, wherein the media presentation comprises a plurality of scenes, and the tags further comprise a time-ordered list of the plurality of scenes.

11. The method of claim 10, wherein the time-ordered list of the plurality of scenes further comprises an initial state of a media item that corresponds to a beginning of the media presentation.

12. The method of claim 10, wherein playing comprises parsing the structured file in accordance with the time-ordered list of the plurality of scenes.

13. The method of claim 12, wherein playing further comprises causing one or more media items from the structured file to be displayed.

14. The method of claim 12, wherein the interpreter interprets the parsed content of the structured file according to a preset preference of the playback device.

15. The method of claim 9, wherein the characteristic of the playback device comprises one or more of:

an operating system, a memory capacity, a display device type, a graphics capability, a playback application type, a communications rate, a communications protocol, a content control setting, an auto-play setting, an audio capability, a volume setting, and a user input capability.

16. A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

access a structured file containing all media items related to a media presentation, wherein at least one of the media items comprises a textured media item;

read, by an interpreter of a playback device, tags associated with the media items related to the media presentation, wherein the tags are for mapping between each of one or more of the media items and for use of each of the one or more media items during playback of the media presentation; and

play, by the playback device, a time-ordered sequence of media items related to the media presentation in accordance with the structured file,

wherein playing includes presenting the at least one textured media item in accordance with a characteristic of the playback device.

17. The non-transitory program storage device of claim 16, wherein the media presentation comprises a plurality of scenes, and the tags further comprise a time-ordered list of the plurality of scenes.

18. The non-transitory program storage device of claim 17, wherein the time-ordered list of the plurality of scenes further comprises an initial state of a media item that corresponds to a beginning of the media presentation.

19. The non-transitory program storage device of claim 17, wherein the instructions to cause the one or more processors to play comprise instructions to cause the one or more processors to parse the structured file in accordance with the time-ordered list of the plurality of scenes.

20. The non-transitory program storage device of claim 19, wherein the instructions to cause the one or more processors to play further comprise instructions to cause the one or more processors to cause one or more media items from the structured file to be displayed.

21. The non-transitory program storage device of claim 19, wherein the instructions to cause the one or more processors to play further comprise instructions to cause the one or more processors to cause one or more media items from the structured file to generate sound.

22. The non-transitory program storage device of claim 19, wherein the interpreter interprets the parsed content of the structured file according to a preset preference of the playback device.

23. The non-transitory program storage device of claim 16, wherein the characteristic of the playback device comprises one or more of:

an operating system, a memory capacity, a display device type, a graphics capability, a playback application type, a communications rate, a communications protocol, a content control setting, an auto-play setting, an audio capability, a volume setting, and a user input capability.
