Abstract

A computer display control system comprises a graphics adapter adapted to generate a composited desktop display from at least two different desktop displays where the desktop displays each correspond to a different computer, and where each of the desktop displays are active in the composited desktop display.

Claims

1. A computer display control system, comprising:

a graphics adapter adapted to generate a composited desktop display from at least two different desktop displays, the desktop displays each corresponding to a different computer, the desktop displays both active in the composited desktop display.

2. The system of claim 1, wherein the graphics adapter is adapted to receive graphics image data corresponding to at least one of the desktop displays from a remote computer.

3. The system of claim 1, wherein the graphics adapter is adapted to receive graphics commands associated with at least one of the desktop displays from a remote computer.

4. The system of claim 3, wherein the graphics adapter is adapted to render graphics image data for at least one of the desktop displays via the graphics commands.

5. The system of claim 1, wherein the graphics adapter is adapted to determine a pixel value associated with a background for each of the desktop displays.

6. The system of claim 1, wherein the graphics adapter is adapted to determine whether a pixel value for a background of at least one of the desktop displays corresponds to a source color key.

7. The system of claim 1, wherein the graphics adapter is adapted to automatically change a pixel value of a background of at least one of the desktop displays.

8. The system of claim 1, wherein the graphics adapter is adapted to automatically change a pixel value of a background of at least one of the desktop displays to a pixel value as defined by a source color key.

9. The system of claim 1, wherein the desktop displays comprise a client computer desktop display and at least one remote computer desktop display.

10. The system of claim 1, wherein the graphics adapter is adapted to generate a window having a transparent background corresponding to at least one of the desktop displays.

11. The system of claim 1, wherein the graphics adapter is adapted to determine whether a location of a graphics element associated with at least one of the desktop displays coincides with a location of a graphics element associated with another one of the desktop displays on the composited desktop display.

12. The system of claim 1, wherein the graphics adapter is adapted to automatically relocate a graphics element from at least one of the desktop displays that coincides with a location of a graphics element associated with another one of the desktop displays on the composited desktop display.

13. The system of claim 1, wherein the graphics adapter is adapted to determine a display priority for graphics elements associated with at least one of the desktop displays.

14. A computer display control method, comprising:

retrieving graphics image data associated with at least two different desktop displays, the desktop displays each corresponding to different computers; and

generating a composited desktop display based on each of the desktop displays, each of the desktop displays active in the composited desktop display.

15. The method of claim 14, further comprising receiving graphics image data corresponding to at least one of the desktop displays from a remote computer.

16. The method of claim 14, further comprising receiving graphics commands corresponding to at least one of the desktop displays from a remote computer.

17. The method of claim 16, further comprising rendering graphics image data corresponding to the at least one of the desktop displays via the graphics commands.

18. The method of claim 14, further comprising determining a pixel value associated with a background for each of the desktop displays.

19. The method of claim 14, further comprising determining whether a pixel value for a background of at least one of the desktop displays corresponds to a source color key.

20. The method of claim 14, further comprising automatically changing a pixel value of a background of at least one of the desktop displays.

21. The method of claim 14, further comprising automatically changing a pixel value of a background of at least one of the desktop displays to a pixel value as defined by a source color key.

22. The method of claim 14, further comprising generating a window having a transparent background corresponding to at least one of the desktop displays.

23. The method of claim 14, wherein retrieving graphics image data comprises retrieving graphics image data corresponding to a client computer desktop display and at least one remote computer desktop display.

24. The method of claim 14, further comprising determining whether a location of a graphics element associated with at least one of the desktop displays coincides with a location of a graphics element associated with another one of the desktop displays on the composited desktop display.

25. The method of claim 14, further comprising determining a display priority for graphics elements associated with at least one of the desktop displays.

26. The method of claim 14, further comprising automatically relocating a graphics element associated with at least one of the desktop displays that coincides with a location of a graphics element associated with another one of the desktop displays on the composited desktop display.

27. A computer display control system, comprising:

means for retrieving graphics image data associated with at least two different desktop displays, each of the desktop displays corresponding to a different computer; and

means for generating a composited desktop display based on each of the desktop displays, each of the desktop displays active in the composited desktop display.

28. The system of claim 27, further comprising means for rendering graphics image data corresponding to at least one of the desktop displays via graphics commands received from a computer corresponding to the respective desktop display.

29. The system of claim 27, further comprising means for determining whether a pixel value for a background of at least one of the desktop displays corresponds to a source color key.

30. The system of claim 27, further comprising means for determining a display priority for graphics elements associated with at least one of the desktop displays.

31. The system of claim 27, further comprising means for automatically changing a pixel value of a background of at least one of the desktop displays to a pixel value as defined by a source color key.

32. A computer display control system, comprising:

a graphics adapter adapted to simultaneously display a client computer desktop and at least one remote computer desktop on a display device, the client computer desktop and the at least one remote computer desktop simultaneously active on the display device.

33. The system of claim 32, wherein the graphics adapter is adapted to designate a pixel value associated with a background of the at least one remote computer desktop as a source color key.

34. The system of claim 32, wherein the graphics adapter is adapted to display a background of the at least one remote computer desktop as a transparent background.

35. The system of claim 32, wherein the graphics adapter is adapted to simultaneously display graphics elements associated with the client computer desktop and the at least one remote computer desktop.

36. The system of claim 32, wherein the graphics adapter is adapted to access priority data to determine a display priority for a graphics element of the client computer desktop coinciding with a location of a graphics element of the at least one remote computer desktop.

37. The system of claim 32, wherein the graphics adapter is adapted to automatically change a pixel value of a background of the at least one remote computer desktop.

38. The system of claim 32, wherein the graphics adapter is adapted to compare a pixel value corresponding to the at least one remote computer desktop with a source color key.

39. The system of claim 32, wherein the graphics adapter is adapted to render graphics image data corresponding to the at least one remote computer desktop based on graphics commands received from a corresponding remote computer.
