Abstract

Methods, systems and computer program products are provided for accessing an alternative display from a data processing system by automatically discovering the accessibility of a display server operably associated with a network upon connection of the data processing system with the network. Display information corresponding to display content to be rendered by a display of the data processing system is generated and provided to the display server over the network so as to allow the corresponding display content to be rendered by the display server on a display associated with the display server.

providing to the display server over the network, the generated display information so as to allow the corresponding display content to be rendered by the display server on a display associated with the display server.

3. A method according to claim 1, wherein the step of generating comprises the step of receiving at the data processing system information to be displayed on the display of the data processing system.

4. A method according to claim 3, wherein the step of providing comprises the step of forwarding the received information to the display server.

5. A method according to claim 1, wherein the step of providing comprises the step of posting the generated display information to the display server so as to render the corresponding display content on the display associated with the display server.

6. A method according to claim 1, wherein the generated display information comprises a markup language page.

7. A method according to claim 6, wherein the markup language comprises at least one of Hypertext Markup Language (HTML), Wireless Markup Language (WML), Voice Extensible Markup Language (VoiceXML) and Extensible Markup Language (XML).

8. A method according to claim 5, wherein the step of posting the generated display information comprises the step of transmitting at least one of an HTTP POST message and a Wireless Session Protocol (WSP) POST message to the display server.

9. A method according to claim 1, wherein the data processing system comprises a pervasive computing device.

10. A method according to claim 1, wherein the network comprises a network incorporated into a mobile vehicle.

11. A method according to claim 1, wherein the display content to be rendered by a display of the data processing system and the corresponding display content to be rendered by the display server on a display associated with the display server represent the same information content.

2. A method of accessing an alternative display from a data processing system, the method comprising the steps of:

automatically discovering the accessibility of a display server operably associated with a network upon connection of the data processing system with the network;

generating, at the data processing system, display information corresponding to display content to be rendered by a display of the data processing system;

providing to the display server over the network, the generated display information so as to allow the corresponding display content to be rendered by the display server on a display associated with the display server; and

wherein the step of automatically discovering the accessibility of a display server comprises the steps of;

detecting connection of the data processing system with the network;

broadcasting a service discovery request on the network responsive to detecting connection of the data processing system with the network;

receiving a response to the broadcast service discovery request; and

evaluating the received response so as to discover the accessibility of the display server.

12. A system for accessing an alternative display from a data processing system, comprising:

means for automatically discovering the accessibility of a display server operably associated with a network upon connection of the data processing system with the network;

means for generating display information of an application program executing at the data processing system corresponding to display content to be rendered by a display of the data processing system; and

means for providing to the display server over the network, the generated display information so as to allow the corresponding display content to be rendered by the display server on a display associated with the display server.

14. A system according to claim 12, wherein the means for generating comprises means for receiving at the data processing system information to be displayed on the display of the data processing system.

15. A system according to claim 14, wherein the means for providing comprises means for forwarding the received information to the display server.

16. A system according to claim 12, wherein the means for providing comprises means for posting the generated display information to the display server so as to render the corresponding display content on the display associated with the display server.

17. A system according to claim 12, wherein the generated display information comprises a markup language page.

18. A system according to claim 17, wherein the markup language comprises at least one of Hypertext Markup Language (HTML), Wireless Markup Language (WML), Voice Extensible Markup Language (VoiceXML) and Extensible Markup Language (XML).

19. A system according to claim 16, wherein the means for posting the generated display information comprises means for transmitting at least one of an HTTP POST message and a Wireless Session Protocol (WSP) POST message to the display server.

20. A system according to claim 12, wherein the data processing system comprises a pervasive computing device.

21. A system according to claim 12, wherein the network comprises a network incorporated into a mobile vehicle.

22. A system according to claim 12, wherein the display content to be rendered by a display of the data processing system and the corresponding display content to be rendered by the display server on a display associated with the display server represent the same information content.

13. A system for accessing an alternative display from a data processing system, comprising:
