Abstract

In one embodiment, a multimedia control and distribution architecture is provided. A media server/controller generates a plurality of graphics signals, each graphics signal including a separate user interface to be displayed on a particular device, such as a touch screen unit. A universal extender (UVX) coupled to the media server/controller converts and extends the graphics signals for transmission on a plurality of universal transmission pathways. Each of the plurality of devices receives a graphic signal passed thereto, displays graphics embodied in the graphics signals, and accept user input in response to the graphics signal. For example, the one or more touch screen units may accept a user touch and pass a location of the user touch back on a universal transmission pathway to the UVX, for transmission to the media server/controller. The media server/controller generates control commands and provides the control commands.

Claims

1. A system comprising:

a media server/controller configured to generate a plurality of graphics signals, each graphics signal including a separate user interface to be displayed on a particular device of a plurality of devices, the plurality of devices including one or more touch screen units;

a universal extender (UVX) coupled to the media server/controller, the UVX configured to receive the plurality of graphics signals, to convert and extend the graphics signals, and to pass each graphics signal to a particular device; and

each of the plurality of devices configured to receive the graphic signal passed thereto, to display graphics embodied in the graphics signals, the one or more touch screen units further configured to accept a user touch and to pass a location of the user touch back to the UVX for transmission to the media server/controller;

wherein the media server/controller is further configured to generate control commands in response to the location of the user touch and to provide the control commands.

2. The system of claim 1 wherein the one or more touch screen units lack processing capabilities to interrelate the location of the user touch with displayed content.

3. The system of claim 1 wherein the one or more touch screen units pass the location of the user touch back on the universal transmission pathway as an x-axis and an y-axis coordinate.

4. The system of claim 1 wherein the UVX is further configured to pass each graphics signal on a separate universal transmission pathway to a particular device coupled thereto.

5. The system of claim 4 wherein each universal transmission pathway comprises at least one Category 5 (CAT5) cable.

6. The system of claim 1 further comprising:

at least one bi-directional data link that couples the media server/controller and the UVX and is configured to pass control information.

7. The system of claim 6 wherein the at least one bi-directional data link is configured to pass one or more audio streams.

8. The system of claim 6 wherein the one or more touch screen units are further configured to pass an audio stream back to the UVX.

9. The system of claim 1 wherein the plurality of devices including an on-screen display (OSD) processing unit, the OSD processing unit configured to combine a graphics signal from the media server/controller received with a video signal from another source.

10. The system of claim 9 wherein the another source is a local video source.

11. The system of claim 9 wherein the graphics signal includes a plurality of graphics frames and at least some graphics frames include one or more regions having pixels set to one or more predetermined color values, and the video signal includes video images corresponding to the plurality of graphics frames and the OSD processing unit further comprises:

a video mixer configured to recognize pixels in each of the at least some graphics frames that are set to the one or more predetermined color values, and in the one or more regions where the pixels are set to the one or more predetermined color values to mix pixels from the corresponding video image with the graphics frame, to create a mixed image.

12. The system of claim 11, wherein the one or more predetermined color values are a pattern of predetermined color values.

13. A method comprising:

generating a plurality of graphics signals at a media server/controller, each graphics signal including a separate user interface to be displayed on a particular device of a plurality of devices, the plurality of devices including one or more touch screen units;

passing each graphics signal to a particular device;

displaying graphics embodied in the graphics signals at each of the plurality of devices, and, for each of the devices that is a touch screen unit,

accepting a user touch, and

passing a location of the user touch back to the media server/controller; and

generating control commands at the media server/controller in response to the location of the user touch and providing the control commands.

14. The method of claim 13 wherein the one or more touch screen units lack processing capabilities to interrelate the location of the user touch with displayed content.

15. The method of claim 13 wherein the one or more touch screen units pass the location of the user touch as an x-axis and a y-axis coordinate.

16. The method of claim 13 further comprising:

converting and extending the graphics signals before passing them to the plurality of devices.

17. The method of claim 13 wherein the step of passing further comprises:

transmitting a graphics signal on a universal transmission pathway that includes at least one Category 5 (CAT5) cable.

18. The method of claim 13 further comprising:

passing an audio stream from the media server/controller to at least one of the plurality of devices.

19. The method of claim 13 further comprising:

passing an audio stream from at least one of the touch screen units to the media server/controller.

20. The method of claim 13 wherein the plurality of devices including an on-screen display (OSD) processing unit, and the OSD processing unit,

combining a graphics signal from the media server/controller with a video signal from another source.

21. The method of claim 20 wherein the another source is a local video source.

22. The method of claim 20 wherein the graphics signal includes a plurality of graphics frames and at least some graphics frames include one or more regions having pixels set to one or more predetermined color values, and the video signal includes video images corresponding to the plurality of graphics frames and the OSD processing unit,

recognizing pixels in each of the at least some graphics frames that are set to the one or more predetermined color values;

and

mixing, in the one or more regions where the pixels are set to the one or more predetermined color values, pixels from the corresponding video image with the graphics frame, to create a mixed image.

23. The method of claim 22, wherein the one or more predetermined color values is a pattern of predetermined color values.

24. A system comprising:

means for generating a plurality of graphics signals, each graphics signal including a separate user interface to be displayed on a particular device of a plurality of devices, the plurality of devices including one or more touch screen units;

means for passing each graphics signal to a particular device;

means for displaying graphics embodied in the graphics signals at each of the plurality of devices, and, at each of the devices that is a touch screen unit,

means for accepting a user touch, and

means for passing a location of the user touch back to the media server/controller; and

means for generating control commands in response to the location of the user touch and providing the control commands.
