Abstract

In one aspect the invention relates to a method for generating a graphical display for a remote terminal session. The method includes monitoring output produced by an application program executing on a server, identifying a bitmap representation within the output produced by the application program and determining a check value for the bitmap representation. The method also includes retrieving a compressed data format of the bitmap representation based at least in part on the check value and transmitting to the remote terminal session the compressed data format in place of the bitmap representation.

Claims

1. A method for generating a graphical display, the method comprising:

analyzing display output via an output filter, the display output generated by an application executing on a first computing device, and displayed on a display device connected to a second computing device;

identifying, by the output filter, display data within the display output;

calculating, by the output filter, a value representative of the display data;

searching, by the output filter, a repository for the calculated value; and

retrieving, from the repository, a compressed format data element corresponding to the display data and having an identifier corresponding to the calculated value.

2. The method of claim 1, wherein identifying display data further comprises identifying non-textual elements.

3. The method of claim 1, wherein identifying display data further comprises identifying display elements transmitted as image data.

4. The method of claim 1, wherein calculating further comprises calculating a string representative of the display data.

5. The method of claim 1, wherein calculating further comprises calculating a check value representative of the display data.

6. The method of claim 1, wherein searching further comprises searching a repository installed on the first computing device.

7. The method of claim 1, wherein searching further comprises searching a repository installed on the second computing device.

8. The method of claim 1, wherein searching further comprises searching a repository having a first portion installed on the first computing device and having a second portion installed on the second computing device.

9. The method of claim 1, wherein searching further comprises searching a repository installed on a third computing device.

10. The method of claim 1, wherein searching further comprises searching a repository having a portion installed on a third computing device.

11. The method of claim 1, further comprising:

determining the retrieved compressed data format element does not exist on the second computing device in communication with the first computing device; and

transmitting the retrieved compressed data format element from the first computing device to the second computing device.

12. The method of claim 1, further comprising:

determining a rendering component does not exist on the second computing device in communication with the first computing device; and

transmitting the display data from the first computing device to the second computing device.

13. A system for generating a graphical display, the system comprising:

an output filter for analyzing display output generated by an application executing on a first computing device, and displayed on a display device connected to a second computing device, identifying display data within the display output, calculating a value representative of the display data, and searching a repository for the calculated value; and

a system component for retrieving a compressed format data element corresponding to the display data and having an identifier corresponding to the calculated value.

14. The system of claim 13, wherein the output filter identifies non-textual elements.

15. The system of claim 13, wherein the output filter identifies display elements transmitted as image data.

16. The system of claim 13, wherein the output filter calculates a string representative of the display data.

17. The system of claim 13, wherein the output filter calculates a check value representative of the display data.

18. The system of claim 13, wherein the output filter searches a repository installed on the first computing device.

19. The system of claim 13, wherein the output filter searches a repository installed on the second computing device.

20. The system of claim 13, wherein the output filter searches a repository having a first portion installed on the first computing device and having a second portion installed on the second computing device.

21. The system of claim 13, wherein the output filter searches a repository installed on a third computing device.

22. The system of claim 13, wherein the output filter searches a repository having a portion installed on a third computing device.

23. The system of claim 13, wherein the output filter:

determines the retrieved compressed data format element does not exist on the second computing device in communication with the first computing device; and

transmits the retrieved compressed data format element from the first computing device to the second computing device.

24. The system of claim 13, wherein the output filter:

determines a rendering component does not exist on the second computing device in communication with the first computing device; and

transmits the display data from the first computing device to the second computing device.
