Abstract

A TV graphical user interface (GUI) is provided to produce a multi-layered graphical presentation. The TV GUI operates in a channel changer mode to enable a user to tune to a required TV channel, and in a program guide mode to show TV program information. A memory for storing graphics data is capable of storing two graphics planes that represent upper and lower layers of graphics displayable on a TV screen. A graphics accelerator combines the graphics planes to produce various graphical effects on the screen. In the channel changer mode, the right hand side of the upper layer is made transparent to expose graphical buttons produced in the lower layer of graphics. In the program guide mode, the graphical buttons are partially covered by a program guide produced in the upper layer. When the user moves a cursor to the right hand side of the screen, the right hand portion of the program guide is made transparent to fully expose the graphical buttons in the lower layer.

Claims

1. A television (TV) system comprising:

a CPU, and

a TV monitor controlled by said CPU for displaying on a TV screen a TV program guide in a first layer of graphics, and at least one graphical object in a second layer of graphics underneath said first layer,

wherein the CPU is configured to automatically adjust the size of said TV program guide in accordance with a position of a cursor to expose at least a portion of said graphical object.

2. The system of claim 1, wherein said TV monitor displays a channel selector and said graphical object in a channel selection mode.

3. The system of claim 2, wherein said TV monitor displays said TV program guide and said graphical object in a program guide mode, and said TV program guide and said graphical object being concurrently accessible.

4. The system of claim 3, wherein said TV program guide partially covers said graphical object when said cursor is outside a predetermined region on the TV screen.

5. The system of claim 4, wherein the size of said TV program guide is reduced to fully expose said graphical object when said cursor is over said predetermined region on the TV screen.

6. The system of claim 5, wherein a portion of said TV program guide is made transparent to expose said graphical object.

7. The system of claim 6, wherein said graphical object comprises an icon for controlling TV operations.

8. The system of claim 7, wherein said icon is activated when said graphical object is fully exposed.

9. The system of claim 8, wherein said icon is deactivated when said graphical object is partially covered by said TV program guide.

10. The system of claim 9, wherein said TV program guide comprises TV program objects for indicating TV programs for a first time period when said cursor is outside said predetermined region on the TV screen.

11. The system of claim 10, wherein said TV program objects are reduced to indicate TV programs for a second time period less than said first time period, when said cursor is over said predetermined region on the TV screen.

12. The system of claim 1, further comprising a graphics data memory for storing multiple graphics planes that represent multiple layers of graphics that are concurrently displayable and accessible on the TV screen.

13. The system of claim 12, further comprising a graphics accelerator for combining said graphics planes to produce various graphical effects on the screen.

14. In a television system, a method for displaying a graphical user interface (GUI), comprising the steps of:

producing a TV program guide in a first layer of graphics displayed on a TV screen,

producing at least one graphical object in a second layer of graphics underneath said first layer, said graphical object being partially covered by said TV program guide, said first layer and said second layer being contemporaneously accessible, and

reducing the size of said TV program guide to fully expose said graphical object automatically when a cursor is moved into a predetermined region on the TV screen.

15. The method of claim 14, further comprising the step of automatically increasing the size of said TV program guide to partially cover said graphical object when the cursor is moved out of said predetermined region.

16. The method of claim 15, further comprising the step of producing a TV channel selector in said first layer to fully expose said graphical object in said second layer of graphics, and said first layer and said second layer being concurrently viewable and accessible.

17. The method of claim 14, further comprising the step of storing graphics data in first and second graphics planes respectively, and said graphics data being concurrently displayable and accessible in said first and second layers of graphics.

18. A system for displaying a graphical user interface comprising:

a CPU, and

a display controlled by said CPU for displaying a first graphical object in a first layer of graphics, and a second graphical object in a second layer of graphics underneath said first layer,

wherein a first predetermined portion of said first graphical object is made transparent in a first mode to expose a predetermined portion of said second graphical object.

19. The system of claim 18, wherein a second predetermined portion of said first graphical object is made transparent in a second mode to fully expose said second graphical object.
