Abstract

A system of multimedia display on a monitor screen includes at least one graphics source, a display file defining a page having a plurality of buttons, where each button has a set of properties including a specification of a graphics source. The system further includes a graphics controller operable to generate a pixel map, and a graphics arbitrator coupled to the graphics controller operable to select pixels between the pixel map and pixels from the at least one graphics source to be displayed for the page according to the display file.

Claims

1. A system of multimedia display on a monitor screen, comprising:

at least one graphics source;

a display file defining a page having a plurality of buttons, each button having a set of properties including a specification of a graphics source;

a graphics controller operable to generate a pixel map; and

a graphics arbitrator coupled to the graphics controller and operable to select pixels between the pixel map and pixels from the at least one graphics source to be displayed for the page according to the display file.

2. The system, as set forth in claim 1, wherein the button properties further ^˜

comprises;

location of the button on the screen; and

size of the button.

3. The system, as set forth in claim 1, wherein the at least one graphics source comprises a video cassette recorder.

4. The system, as set forth in claim 1, wherein the at least one graphics source comprises a camera.

5. The system, as set forth in claim 1, wherein the at least one graphics source comprises a television signal receiver.

6. The system, as set forth in claim 1, wherein the at least one graphics source comprises a computer.

7. The system, as set forth in claim 1, further comprising a control area network coupled to the display interface.

8. The system, as set forth in claim 7, wherein the control area network comprises:

a master controller;

at least one control device;

at least one graphics source;

a network coupled to the master controller, the at least one control device, the at least one graphics source, and the display interface.

9. The system, as set forth in claim 1, further comprising an editor operable to edit the button properties.

10. A control area network having a multimedia display, comprising:

a master controller coupled to the control area network;

at least one control device coupled to the master controller via the control area network, the at least one control device comprising;

at least two graphics sources;

a display file defining a page having a plurality of buttons, each button having a set of properties including a specification of a graphics source;

a graphics controller operable to generate a pixel map; and

a graphics arbitrator coupled to the graphics controller and operable to select pixels between the pixel map and pixels from the at least two graphics sources to be displayed on a monitor screen for the page according to the display file.

11. The system, as set forth in claim 10, wherein the button properties further comprises:

location of the button on the screen; and

size of the button.

12. The system, as set forth in claim 10, wherein the at least two graphics sources comprise a video cassette recorder.

13. The system, as set forth in claim 10, wherein the at least two graphics sources comprise a camera.

14. The system, as set forth in claim 10, wherein the at least two graphics sources comprise a television signal receiver.

15. The system, as set forth in claim 10, wherein the at least two graphics sources comprise a computer.

16. The system, as set forth in claim 10, further comprising an editor operable to edit the button properties.

17. The system, as set forth in claim 10, wherein the monitor is a touch panel.

18. A method of multimedia display on a monitor screen, comprising:

composing a display file describing multiple buttons, each button having a set of properties including a specification of a graphics source;

receiving a pixel from each graphics source;

generating a corresponding pixel in response to the display file;

examining the generated pixel; and

selecting and displaying from the generated pixel and the corresponding pixels from the graphics sources in response to examining the generated pixel.

19. The method, as set forth in claim 18, wherein examining the generated pixel comprises determining whether each pixel has a predetermined key color value, each key color value indicative of a specific graphics source.

20. The method, as set forth in claim 18, further comprising outputting the selected pixel to monitor screen for display.

21. The method, as set forth in claim 18, wherein selecting the pixel comprises:

selecting the generated pixel in response to the generated pixel not matching any predetermined key color value; and

selecting the received pixel from a graphics source in response to the generated pixel matching a predetermined key color value representing the graphics source.

22. A method of multimedia display on a touch monitor screen in a control area network, comprising:

composing a display file describing multiple buttons, each button having a set of properties including a specification of a graphics source coupled to the control area network;

receiving a pixel from each graphics source;

generating a corresponding pixel in response to the display file;

examining the generated pixel; and

selecting and displaying from the generated pixel and the corresponding pixels from the graphics sources in response to examining the generated pixel.

23. The method, as set forth in claim 22, wherein examining the generated pixel comprises determining whether each pixel has a predetermined key color value, each key color value indicative of a specific graphics source.

24. The method, as set forth in claim 22, further comprising outputting the selected pixel to monitor screen for display.

25. The method, as set forth in claim 22, wherein selecting the pixel comprises:

selecting the generated pixel in response to the generated pixel not matching any predetermined key color value; and

selecting the received pixel from a graphics source in response to the generated pixel matching a predetermined key color value representing the graphics source.
