Abstract

A system and method includes a host device, an intermediate device and a user device having a device type associated therewith. A network is in communication with the host device, the intermediate device and the user device. The host device communicates a first graphics command to the intermediate device. The intermediate device converts the first graphics command to a second graphics command in response to the device type. The user device generates a screen display in response to the second graphics command.

Claims

1. A system comprising:

a first device having a device type associated therewith;

an intermediate device;

a second device having a device type associated therewith; and

a network in communication with the first device, the intermediate device and the second device;

said first device communicating a first command to the intermediate device;

said intermediate device converting the first command to a second command in response to the device type;

said second device processes the second command after receiving the second command from the intermediate device.

2. The system as recited in claim 1 wherein the first device comprises a server device, the second device comprises a user device, the first and second command comprises graphics commands and the user device generates a screen display in response to the second graphics command.

3. The system as recited in claim 1 wherein the intermediate device comprises a server and the second device comprises a browser that communicates with the server, said browser downloading an application from the server that establishes a WebSocket connection to the intermediate device, said second graphics command readable by the application.

4. The system as recited in claim 2 wherein the user device forms a WebSocket connection with the intermediate device.

5. The system as recited in claim 3 wherein the application comprises a JavaScript application.

6. The system as recited in claim 5 wherein the second graphics command comprises a JavaScript Object Notation (JSON) command.

7. The system as recited in claim 3 wherein the server comprises an HTTP server and the browser comprises an HTML browser.

8. The system as recited in claim 3 wherein the second device generates a response signal from the browser and communicates the response signal to the server of the intermediate device.

9. The system as recited in claim 2 wherein the second graphics command comprises a binary graphics command.

10. The system as recited in claim 9 wherein the intermediate device converts the first graphics command to the second graphics command comprising text using one of base64, PNG or JPG encoding.

11. The system as recited in claim 1 wherein the second device generates a JavaScript Object Notation (JSON) response command and communicates the JSON response command to the intermediate device, said intermediate device converting the JSON response command to an XML response command, said intermediate device communicating the XML response command to the host device.

12. The system as recited in claim 1 wherein the first device comprises a user device, the second device comprises a server device, the first and second command comprises user event commands and the server device processes the second user event command.

13. The system as recited in claim 12 wherein the user device generates a JavaScript Object Notation (JSON) user command and communicates the JSON user command to the intermediate device, said intermediate device converting the JSON user command to an XML user command, said intermediate device communicating the XML user command to the host device.

14. The system as recited in claim 12 wherein the JavaScript application receives the HTML browser user events, converts the HTML browser user events into JSON user commands, and communicates the JSON user commands to the intermediate device.

15. A method comprising:

communicating a device type signal from a first device to an intermediate device;

communicating a first command from a first device to the intermediate device;

converting the first command to a second command in response to the device type signal at the intermediate device;

communicating the second command from the intermediate device to the second device; and

processing the second command at the second device upon receiving it from the intermediate device.

16. The method as recited in claim 15 wherein the first device comprises a server device, the second device comprises a user device, the first and second command comprises graphics commands and the user device generates a screen display in response to the second graphics command.

17. The method as recited in claim 16 further comprising downloading an application using a browser of the user device from a server of the intermediate device that establishes a communication to the intermediate device, and wherein converting comprises converting the second graphics command to a format readable by the application.

18. The method as recited in claim 17 wherein the communication comprises a WebSocket.

19. The method as recited in claim 17 further comprising generating a response signal from the browser and communicates the response signal to the server of the intermediate device.

20. The method as recited in claim 17 wherein downloading an application comprises downloading the application comprising a JavaScript application and wherein converting the first graphics command to a second graphics command comprises converting the first graphics command to the second graphics command comprising a JavaScript Object Notation (JSON) command.

21. The method as recited in claim 16 further comprising downloading an application using an HTML browser of the user device from an HTTP server of the intermediate device that establishes a WebSocket connection to the intermediate device, and wherein converting comprises converting the second graphics command to a format readable by the application.

22. The method as recited in claim 16 wherein converting the first graphics command to the second graphics command comprises converting the first graphics command to a binary graphics command.

23. The method as recited in claim 22 wherein converting comprises converting the first graphics command to the second graphics command comprising text using base64, PNG or JPG encoding.

24. The method as recited in claim 16 further comprising generating a JavaScript Object Notation (JSON) response command from the user device, communicating the JSON response command from the user device to the intermediate device, converting the JSON response command to an XML response command at the intermediate device, and communicating the XML response command to the host device.

25. The method as recited in claim 15 wherein the first device comprises a user device, the second device comprises a server device, the first and second command comprises user event commands and the server device processes the second user event command.

26. The method as recited in claim 25 further comprising generating a JavaScript Object Notation (JSON) user command from the user device, communicating the JSON user command from the user device to the intermediate device, converting the JSON user command to an XML user command at the intermediate device, and communicating the XML user command to the host device.

27. The method as recited in claim 26 further comprising a JavaScript application receiving the HTML browser user events, converting the HTML browser user events into JSON user commands, and communicating the JSON user commands to the intermediate device.
