Abstract

A dynamic publishing system for delivery and presentation of multimedia on a wireless device, such as a PDA or mobile telephone. A presentation server dynamically compiles application data based on scene description data for one or more media objects, and sends the application data to the wireless device for presentation of the media objects. The wireless device has a media player that is able to process the application data at an object level for the objects in response to events, and control the presentation. The application data includes content, layout and control logic data for the media objects.

7. A publishing system claimed in claim 6, wherein said events relate to actions of a user of said wireless device.

8. A publishing system as claimed in claim 1, wherein said scene description data defines one or more scenes including one or more media objects, rendering of said one or more media objects and one or more events associated with said one or more multimedia objects.

9. A publishing system as claimed in claim 8, wherein said application data includes interleaved control packets, media data packets and media definition packets for said media objects.

10. A publishing system as claimed in claim 8, wherein said scene description data includes XML data.

11. A publishing system as claimed in claim 3, wherein said compiling is adjusted on the basis of one or more characteristics of the communications link between said presentation server and said wireless device.

12. A publishing system as claimed in claim 3, wherein said presentation server is adapted to receive capability data from said wireless device indicating capabilities of said wireless device and to modify said application data on the basis of said capability data.

13. A publishing system as claimed in claim 12, wherein said capabilities include hardware capabilities and software capabilities of said wireless device.

14. A publishing system as claimed in claim 13, wherein said presentation server is adapted to send software packets to said wireless device on the basis of said capability data to modify software capabilities of said wireless device.

15. A publishing system as claimed in claim 1, wherein said presentation server is adapted to manage a multimedia object library stored on said wireless device.

16. A publishing system as claimed in claim 2, wherein said presentation server is adapted to receive user form data and events from said wireless device.

17. A publishing system as claimed in claim 1, including an application server for communicating with said presentation server, providing encoded data for said media objects, and generating said scene description data.

18. A publishing system as claimed in claim 17, wherein said application server includes an engine for generating said scene description data on the basis of dynamic pages.

19. A publishing system as claimed in claim 17, wherein said application server is adapted to process user form data sent from said wireless device to said presentation server.

20. A publishing system as claimed in claim 1, wherein said application server is adapted to generate image tile data representing an image as a set of tiles and to send at least part of said image tile data to said wireless device for display of part of said image.

21. A publishing system as claimed in claim 19, wherein said presentation server is adapted to send individual tiles of said set of tiles to said wireless device on demand.

22. A publishing system as claimed in claim 4, wherein said presentation server synchronously accesses media sources for said media objects and sends said application data in packets of a bitstream to said wireless device, whilst said wireless device is executing an application using the application data received.

23. A publishing system as claimed in claim 1, wherein said presentation server incrementally links media sources for said media objects and sends said application data incrementally to a wireless device running an application using the received application data.

24. A publishing system as claimed in claim 1, wherein said presentation server is adapted to send said application data to a plurality of wireless devices running an application using the application data, simultaneously.

25. A publishing system as claimed in claim 1, wherein said presentation server sends said application data to said wireless device as a download.

26. A publishing system as claimed in claim 1, wherein said presentation server sends said application data to said wireless device as a data stream.

27. A publishing system as claimed in claim 1, wherein said presentation server sends a portion of said application data to said wireless device as a download, and the remainder of said application data as a data stream.

28. A media player for a wireless device, including a virtual machine for receiving application data for one or more media objects, processing said application data at an object level for said objects in response to detected events and presenting said objects on said device based on said events.

29. A media player as claimed in claim 28, wherein said application data includes content, layout and control logic data for said media objects.

30. A media player as claimed in claim 29, wherein said logic data defines events for said media objects, respectively.
