Abstract

Systems that employs an adaptable front end for determining a file-type to associate with the output from a source application and for processing the output, as a function of the file type, to generate a display list that is representative of objects and shapes that represent components within the visual presentation of the data. The display list is then processed by a rendering engine, which may be located on an embedded device. The rendering engine processes the components contained within the display list to render an image of the source application'"'"'s output that may be presented on the display of the device. As will be described below, the adaptable front end determines the file structure of the source being processed, thereby providing a device that may operate with a plurality of different file types, and source applications.

Claims

1-12. -12. (cancelled)

13. A data processing system comprising:

an operating system;

a digital document processing system integrated with the operating system for generating an interactive visual display including;

a receiving module for receiving an input bytestream in any of a plurality of predetermined data formats representing source data defining the content and structure of a digital document and including an interactive feature that interacts with the operating system;

an interpreting module for converting the input bytestream into an internal representation of the structure and content;

a rendering module for processing the internal representation data to generate output representation data adapted to enable a display device to render the output representation data to generate the interactive visual display including the interactive feature of the source data, thereby providing a graphical user interface to underlying operating system functions.

14. The data processing system of claim 13 wherein the digital document processing system further comprises an application specific integrated circuit incorporating at least one of the receiving, interpreting, and rendering modules.

15. The data processing system of claim 13 further comprising a RISC-type processor for executing the digital document processing system.

16. The data processing system of claim 15 wherein the RISC-type processor comprises an application specific integrated circuit.

17. The data processing system of claim 13 wherein the digital document processing system is integrated into the operating system at the BIOS level.

18. The data processing system of claim 13 wherein the digital document processing system is integrated into the operating system immediately above the transport protocol stack.

19. The data processing system of claim 13 wherein the digital document processing system is integrated into the operating system through a network device.

20. The data processing system of claim 13 further comprising a projector, wherein the operating system and digital document processing system are incorporated into the projector.

21. The data processing system of claim 13 further comprising a telephone, wherein the operating system and digital document processing system are incorporated into the telephone.

22. The data processing system of claim 13 further comprising a portable digital assistant, wherein the operating system and digital document processing system are incorporated into the portable digital assistant.

23. The data processing system of claim 13 further comprising a set-top box, wherein the operating system and digital document processing system are incorporated into the set-top box.

24. The data processing system of claim of 13 wherein the data processing system further comprises a user input module for receiving user instructions to activate the interactive feature.

25. A data processing system comprising:

an operating system;

a digital document processing system integrated with the operating system for generating an interactive visual display including;

a receiving module for receiving an input bytestream in any of a plurality of predetermined data formats representing source data defining the content and structure of a digital document and including an interactive feature;

an interpreting module for converting the input bytestream into an internal representation of the structure and content;

a rendering module for processing the internal representation data to generate output representation data adapted to enable a display device to render the output representation data to generate the interactive visual display including the interactive feature of the source data, thereby providing a graphical user interface.
