Abstract

A set-top box runs web browser software and displays on a television set a web page comprising hypertext links. A spotlight is used as a focus to navigate the page.

Claims

1. A display generating device configured to generate signals for a graphical display device, comprising a processor for modifying an image by spotlighting a region of the image relative to its surroundings using a trackable spotlight which is slideably movable about the image, wherein an object within said surroundings is visible, wherein said image includes a plurality of objects and wherein said trackable spotlight is slideably movable within the image to move the spotlit region to permit selection of one of the objects of the image that falls within the spotlit region, wherein objects within said surroundings are also visible in addition to the object in the spotlit region.

2. A device according to claim 1, wherein said spotlit region is brighter than its surroundings.

3. A device according to claim 1, wherein said spotlit region is a different color from its surroundings.

4. A device according to claim 1, wherein a first object within said spotlit region has a relatively high contrast against said spotlit region and a second object within said surroundings has a relatively low contrast against said surroundings.

5. A device according to claim 1, wherein a first object within said spotlit region is in sharper focus than a second object within said surroundings.

6. A device according to claim 1, wherein the spotlight is locatable so as to enclose partly or wholly a functional display region so as to permit selection thereof.

7. A device according to claim 1, wherein the spotlight has a diffuse boundary.

8. A device according to claim 1, wherein the spotlight is substantially circular.

9. A multimedia network terminal including a device according to claim 1.

10. A multimedia network terminal according to claim 9, which is an internet-enabled digital television set top box.

11. A device according to claim 1, wherein said spotlit region has a focal point.

12. A device according to claim 11, wherein said focal point is used to select an object.

13. A device according to claim 11, wherein said focal point is used to select a hypertext link.

14. A device according to claim 1 configured to receive directional input and move said spotlight in dependence upon said directional input.

15. A device according to claim 1, wherein, said spotlit region appears relatively light and its surroundings appears relatively dark.

16. A device according to claim 15, wherein a pixel intensity of said spotlit region decreases radially to a base level for said surroundings.

17. A display generating device according to claim 1, wherein the spotlit region is graphically altered from its surroundings.

18. A method, in a display generating device configured to generate signals for a graphical display device, of operating the device, the method comprising modifying an image by spotlighting a region of the image relative to its surroundings using a trackable spotlight which is slideably movable about the image, wherein an object within said surroundings is visible, wherein said image includes a plurality of objects and wherein said trackable spotlight is slideably movable within the image to move the spotlit region to permit selection of one of the objects of the image that falls within the spotlit region, wherein objects within said surroundings are also visible in addition to the object in the spotlit region.

19. A display generating device according to claim 18, wherein the spotlit region is graphically altered from its surroundings.

20. A computer program comprising computer code to make a computer configured to generate signals for a graphical display device execute procedure to modify an image by spotlighting a region of the image relative to its surroundings using a trackable spotlight which is slideably movable about the image, wherein an object within said surroundings is visible, wherein said image includes a plurality of objects and wherein said trackable spotlight is slideably movable within the image to move the spotlit region to permit selection of one of the objects of the image that falls within the spotlit region, wherein objects within said surroundings are also visible in additional to the object in the spotlit region.

21. A display generating device according to claim 20, wherein the spotlit region is graphically altered from its surroundings.

22. A display generating device configured to generate signals for a graphical display device, comprising a processor configured to modify an image by spotlighting a region of the image relative to its surroundings using a trackable spotlight which is slideably movable about the image, wherein an object within said surroundings is visible, wherein said image includes a plurality of objects and wherein said trackable spotlight is slideably movable within the image to move the spotlit region to permit selection of one of the objects of the image that falls within the spotlit region, wherein objects within said surroundings are also visible in addition to the object in the spotlit region.

23. A display generating device according to claim 22, wherein the spotlit region is graphically altered from its surroundings.
