Abstract

An apparatus and method for selecting portions of a displayed image for remote display including displaying a first image, selecting a subset of the displayed first image, and communicating the selected portion of the first image for display on a remote display.

Claims

1. An apparatus for selecting portions of a displayed image for remote display comprising:

means for displaying an image;

means for selecting a portion of the displayed image, said selecting means including means for moving and sizing a view box over said displayed image wherein said portion of said displayed image is determined by size and location of said view box; and

means for communicating the selected portion of the image for display on a remote display.

2. The apparatus of claim 1 wherein the means for displaying includes means for displaying a video image and a graphical image concurrently.

3. The apparatus of claim 2 wherein the means for selecting includes means for selecting a portion of the video image and a portion of the graphical image.

4. The apparatus of claim 3 wherein the means for communicating includes means for communicating the selected portion of the video image and the selected portion of the graphical image for concurrent display on the remote display.

5. The apparatus of claim 4 further comprising means for concurrently displaying on the remote display the selected portion of the video image and the selected portion of the graphical image.

6. A method for selecting portions of a displayed image for remote display comprising the steps of:

displaying an image;

selecting a portion of the displayed image, said selecting step including the step of moving and sizing a view box over said displayed image wherein said portion of said displayed image is determined by size and location of said view box; and

communicating the selected portion of the image for display on a remote display.

7. The method of claim 6 wherein the step of displaying includes displaying a video image and a graphical image concurrently.

8. The method of claim 7 wherein the step of selecting includes selecting a portion of the video image and a portion of the graphical image.

9. The method of claim 8 wherein the step of communicating includes communicating the selected portion of the video image and the selected portion of the graphical image for concurrent display on the remote display.

10. The method of claim 9 further comprising concurrently displaying on the remote display the selected portion of the video image and the selected portion of the graphical image.

11. A data processing system for processing data comprising:

a memory for storing data for processing;

a processor coupled to memory for processing stored data; and

an apparatus coupled to said processor for selecting portions of a displayed image for remote display including;

i) means for displaying an image;

ii) means for selecting a portion of the displayed image, said selecting means including means for moving and sizing a view box over said displayed image wherein said portion of said displayed image is determined by size and location of said view box; and

iii) means for communicating the selected portion of the image for display on a remote display.

12. The data processing system of claim 11 wherein the means for displaying includes means for displaying a video image and a graphical image concurrently.

13. The data processing system of claim 12 wherein the means for selecting includes means for selecting a portion of the video image and a portion of the graphical image.

14. The data processing system of claim 13 wherein the means for communicating includes means for communicating the selected portion of the video image and the selected portion of the graphical image for concurrent display on the remote display.

15. The data processing system of claim 14 further comprises means for concurrently displaying on the remote display the selected portion of the video image and the selected portion of the graphical image.

16. A computer program product stored on a computer readable medium for selecting portions of a displayed image for remote display comprising:

means for displaying an image;

means for selecting a portion of the displayed first image, said selecting means including means for moving and sizing a view box over said displayed image wherein said portion of the displayed image is determined by size and location of said view box; and

means for communicating the selected portion of the image for display on a remote display.

17. The computer program product of claim 16 wherein the means for displaying includes means for displaying a video image and a graphical image concurrently.

18. The computer program product of claim 17 wherein the means for selecting includes means for selecting a portion of the video image and a portion of the graphical image.

19. The computer program product of claim 18 wherein the means for communicating includes means for communicating the selected portion of the video image and the selected portion of the graphical image for concurrent display on the remote display.

20. The computer program product of claim 19 further comprising means for concurrently displaying on the remote display the selected portion of the video image and the selected portion of the graphical image.
