Abstract

An alternate display content controller provides a technique for controlling a video display separately from and in addition to the content displayed on the operating system display surface. Where the display is a computer monitor, the alternate display content controller interacts with the computer utility operating system and hardware drivers to control allocation of display space and create and control one or more parallel graphical user interfaces in addition to the operating system desktop. An alternate display content controller may be incorporated in either hardware or software. As software, an alternate display content controller may be an application running on the computer operating system, or may include an operating system kernel of varying complexity ranging from dependent on the utility operating system for hardware system services to a parallel system independent of the utility operating system and capable of supporting dedicated applications. The alternate display content controller may also include content and operating software delivered over the Internet or any other LAN. The alternate display content controller may also be included in a television decoder/settop box to permit two or more parallel graphical user interfaces to be displayed simultaneously.

Claims

1. A method for enabling the display of an image on a video display system in an area outside of a first display area controlled by a computer operating system window system, the video display system having a total displayable area of which the first display area is a part, comprising:

modifying the total displayable area of the video display system to include a second display area by reducing the size of the first display area that is controlled by the operating system window system, the second display area being controlled by secondary code that is independent of the operating system window system;

allocating a new window to correspond to the second display area;

upon receiving an event from an input/output device, determining whether to route the event to the operating system window system code or to the secondary code; and

routing the event to the determined code, such that input can be received from and output can be rendered to the second display area, in a manner that is transparent to the computer operating system.

2. The method of claim 1 for use in a Unix environment wherein the total displayable area is mapped to a root window and modifying the total displayable area comprises altering a drawable area for the root window.

3. The method of claim 2 wherein the new window is a child window of the root window.

4. The method of claim 1 for use in a Unix environment wherein an adapter resource for the display of information is initially allocated to a window associated with the total displayable area and the adapter resource is split to provide adapter resources for the new window.

5. The method of claim 4 wherein the adapter resource comprises an alternate display content controller trapping adapter codes to modify the total displayable space and to create the second display area.

6. The method of claim 1 for use in a Unix environment wherein the total displayable area is mapped to a root window and modifying the total displayable area comprises generating a plurality of root windows.

7. The method of claim 6 wherein a controller associated with the new window routes the received event to the first and second display areas based on an attribute associated with the received event.

8. The method of claim 1 for use in a Unix environment wherein the total displayable area is mapped to a root window and controlled by a master display server, and modifying the total displayable area comprises generating the second display area controlled by its own display server.

9. The method of claim 8 wherein the master display server is the only display server accessible by the computer operating system.

10. A computer readable media containing computer instructions that cause a computer processor to enable the display of an image on a video display system in an area outside of a first display area controlled by a computer operating system window system, the video display system having a total displayable area of which the first display area is a part, the computer readable media comprising containing computer instructions that cause the computer processor to:

modify the total displayable area of the video display system to include a second display area by reducing the size of the first display area that is controlled by the operating system window system, the second display area being controlled by secondary code that is independent of the operating system window system;

allocate a new window to correspond to the second display area;

upon receiving an event from an input/output device, determine whether to route the event to the operating system window system code or to the secondary code; and

route the event to the determined code, such that input can be received from and output can be rendered to the second display area, in a manner that is transparent to the computer operating system.

11. The computer readable media of claim 10 for use in a Unix environment wherein the total displayable area is mapped to a root window and computer instructions to modify the total displayable area comprises computer instructions to alter a drawable area for the root window.

12. The computer readable media of claim 11 wherein the new window is a child window of the root window.

13. The computer readable media of claim 10 for use in a Unix environment wherein the computer instructions cause an alternate display content controller to trap adapter codes to modify the total displayable space and to create the second display area.

14. The computer readable media of claim 10 for use in a Unix environment wherein the total displayable area is mapped to a root window and the computer instructions to modify the total displayable area comprises computer instructions to generate a plurality of root windows.

15. The computer readable media of claim 14 wherein the computer instructions cause a controller associated with the new window to route the received event to the first and second display areas based on an attribute associated with the received event.

16. The computer readable media of claim 10 for use in a Unix environment wherein the total displayable area is mapped to a root window and controlled by a master display server, and the computer instructions to modify the total displayable area comprises computer instructions to generate the second display area controlled by its own display server.

17. A system to enable the display of an image on a video display system in an area outside of a first display area controlled by a computer operating system window system, the video display system having a total displayable area of which the first display area is a part, the system comprising:

a processor to modify the total displayable area of the video display system to include a second display area by reducing the size of the first display area that is controlled by the operating system window system, the second display area being controlled by secondary code that is independent of the operating system window system; and

a display adapter to;

allocate a new window to correspond to the second display area;

upon receiving an event from an input/output device, determine whether to route the event to the operating system window system code or to the secondary code; and

route the event to the determined code, such that input can be received from and output can be rendered to the second display area, in a manner that is transparent to the computer operating system.

18. The system of claim 17 for use in a Unix environment wherein the total displayable area is mapped to a root window and the processor modifies the total displayable area to alter a drawable area for the root window.

19. The system of claim 18 wherein the new window is a child window of the root window.

20. The system of claim 17 for use in a Unix environment wherein the display adapter traps adapter codes to modify the total displayable space and to create the second display area.

21. The system of claim 17 for use in a Unix environment wherein the total displayable area is mapped to a root window and the display adapter modifies the total displayable area to generate a plurality of root windows.

22. The system of claim 21 wherein the display adapter routes the received event to the first and second display areas based on an attribute associated with the received event.

23. The system of claim 17 for use in a Unix environment wherein the total displayable area is mapped to a root window and controlled by a master display server, and the display adapter generates the second display area controlled by its own display server.
