Abstract

Screen bum on televisions having Internet browser capability is avoided by removing the conventional static icons such as toolbars and buttons from the default browser and replacing their functions with keyboard keys. The invention is especially useful in projection televisions and with keyboards which have keys assigned to browser functions. Favorite URLs can be mapped to a favorite key by holding down the favorite key while a favorite web page is displayed.

Claims

1. A television apparatus capable of providing a web browser, said television apparatus comprising:

means for receiving a user input to invoke said web browser;

means for enabling display of said web browser responsive to said user input, and for enabling display of television signals while said web browser is not displayed; and

wherein when said web browser is displayed;

no static icons are displayed, and user functions corresponding to said static icons are provided via a pop-up menu;

said web browser automatically closes and said television signals are displayed after an idle timeout interval elapses; and

said idle timeout interval varies based on a manner in which said web browser was invoked.

2. The television apparatus of claim 1, wherein said user functions include favorites, home, back, forward, stop, refresh, close browser, search, address bar, and text size.

3. The television apparatus of claim 1, wherein said pop-up menu is displayed responsive to user depression of a key of a user input device.

4. The television apparatus of claim 3, wherein said user input device includes a pointing device.

5. The television apparatus of claim 1, wherein said idle timeout interval equals a first time period if said web browser was invoked via a menu and equal a second time period if said web browser was invoked via a keyboard, said first time period being different from said second time period.

6. The television apparatus of claim 5, further comprising projection display means for displaying either said television signals or said web browser.

7. The television apparatus of claim 5, wherein said first time period is less than said second time period.

8. The television apparatus of claim 1, further comprising input/output means for enabling access to the Internet via at least one of a cable connection, a DSL connection, and a modem.

9. The television apparatus of claim 1, wherein said user functions are mapped to keyboard keys.

10. The television apparatus of claim 9, wherein said user functions are mapped to said keyboard keys according to at least one of:

a favorites function to favorite keys, a back function to a back key, a forward function to a forward key, an open function to an open key, a close browser function to a clear key, a close window function to a close window key, a search function to a search key, a previous window function to a previous window key, a next window function to a next window key, a display address bar function to an address key, a find text function to a find text key, a text size increase function to a text size increase key, an up function to an up key, a down function to a down key, a right function to a right key, and a left function to a left key.

11. The television apparatus of claim 1, wherein:

a favorite web page is mapped to a favorite key of a user input device upon pressing said favorite key; and

after said favorite web page is mapped to said favorite key, said favorite web page is opened in response to depression of said favorite key.

12. A method for providing a web browser via a television apparatus, said method comprising:

receiving a user input to invoke said web browser;

enabling display of said web browser responsive to said user input;

enabling display of television signals while said web browser is not displayed; and

wherein when said web browser is displayed;

no static icons are displayed, and user functions corresponding to said static icons are provided via a pop-up menu;

said web browser automatically closes and said television signals are displayed after an idle timeout interval elapses; and

said idle timeout interval varies based on a manner in which said web browser was invoked.

13. The method of claim 12, wherein said user functions include favorites, home, back, forward, stop, refresh, close browser search, address bar, and text size.

14. The method of claim 12, wherein said web browser and said television signals are displayed via a projection television.

15. The method of claim 12, wherein said user functions are mapped to keyboard keys.

16. The method of claim 15, wherein said user functions are mapped to said keyboard keys according to at least one of:

a favorites function to favorite keys, a back function to a back key, a forward function to a forward key, an open function to an open key, a close browser function to a clear key, a close window function to a close window key, a search function to a search key, a previous window function to a previous window key, a next window function to a next window key, a display address bar function to an address key, a find text function to a find text key, a text size increase function to a text size increase key, an up function to an up key, a down function to a down key, a right function to a right key, and a left function to a left key.

17. The method of claim 12, further comprised of bookmarking a favorite web page provided via said web browser in response to detecting user depression of a key for a threshold time period while said favorite web page is being displayed.

18. The method of claim 12, wherein said idle timeout interval equals a first time period if said web browser was invoked via a menu and equals a second time period if said web browser was invoked via a keyboard, said first time period being less than said second time period.
