Abstract

Claims (29)

1. A method for use in a video production switcher for providing video signals for use in displaying an image on a display, the method comprising:

mapping an image to a global space, the global space associated with the display;

defining a local space for each mix effects unit, wherein the local space is part of the global space;

mapping the image from the global space to at least one local space to determine which mix effects unit displays the image; and

calculating a transform matrix for at least one mix effects unit to display the image mapped to the at least one mix effect unit assigned to the local space on the global space, wherein the image may be partially displayed at various times using more than one mix effects unit.

2. The method of claim 1 , further comprising the step of:

assigning at least one of the number of local spaces to a particular portion of the global space.

3. The method of claim 2 , wherein the assigning step assigns at least two of the local spaces to the global space such that those assigned local spaces are adjacent in the global space.

4. The method of claim 2 , wherein the assigning step assigns at least two of the local spaces to the global space such that those assigned local spaces are separated by a gap in the global space not covered by any other local space.

5. The method of claim 2 , wherein the assigning step comprises:

displaying a graphical user interface which comprises a representation of the global space and a representation of at least one of the number of local spaces;

wherein the graphical user interface allows the representation of the at least one of the number of local spaces to be arranged within the representation of the global space for assignment to the particular portion of the global space.

6. The method of claim 5 , wherein a size of the local space is adjustable.

7. Apparatus comprising:

a number of mix effects units, each mix effects unit providing a video output signal for use in displaying images on a display, wherein each mix effects unit is mapped from a global space to at least one local space to determine which mix effects unit displays the image, wherein the image may be partially displayed at various times using more than one mix effects unit; and

a controller for controlling the presentation of a video effect on the display by each mix effects unit as a function of a mapping between a local space assigned to each mix effects unit and a global space associated with the display.

8. The apparatus of claim 7 , wherein the controller provides a transform matrix that remaps at least a portion of the video effect from a global space associated with the display to at least one of the local spaces.

9. The apparatus of claim 8 , wherein the controller assigns at least one of the local spaces to a particular portion of the global space.

10. The apparatus of claim 9 , wherein the controller assigns two of the local spaces to the global space such that those two assigned local spaces are adjacent in the global space.

11. The apparatus of claim 9 , wherein the controller assigns two of the local spaces to the global space such that those two assigned local spaces are separated by a gap in the global space not covered by any other local space.

12. The apparatus of claim 7 , further comprising

a number of projector devices, each projector device associated with one of the mix effects units, wherein each projector device is responsive to the video output signal from its mix effects unit for displaying an image on the display.

13. The apparatus of claim 12 , further comprising the display, which includes a number of screens, wherein each screen is mapped to one of the mix effects units.

14. The apparatus of claim 7 , wherein at least one local space is smaller than a display area of the display.

15. The apparatus of claim 7 , wherein the controller comprises a memory for storing a mapping between each local space and the respective display.

16. The apparatus of claim 7 , further comprising

a second display for displaying a graphical user interface which comprises a representation of a global space representing the display and a representation of at least one of the number of local spaces;

wherein the graphical user interface allows the representation of the at least one of the number of local spaces to be arranged within the representation of the global space for assignment to the particular portion of the global space.

17. The apparatus of claim 16 , wherein a size of the local space is adjustable.
