Abstract

The invention discloses a portable device providing access to the Internet. A host computer runs a browser taking information received from the Internet, renders it onto a virtual display in memory, reduces the color depth, compress and sends it to the device. Thus, the user views a bit map or raster image of a Web page on the device, which also contains a browser software program, that runs on the device containing its own window. This window contains buttons or icons providing web functions and implements scrolling on the web page received with respect to the window. The windows of the browsers in the host computer and device are adjustable in size and may be set to match for text formatting. The size of the web page received from the Internet is the size sent to the device when converted to an image, which varies with each web page received.

Claims

1. A method to view Internet content, the method comprising:

displaying in a first portion of a display of a device a user interface image including one or more buttons for web browsing;

sending a request for a web page from the device to a remote server;

receiving at the device from the remote server in a compressed format a web page image, the web page image being rendered at the remote server from the entire web page which the remote server retrieves from the Internet in response to the request, the web page including text and graphics; and

under exclusive control of the device, selectively displaying a portion of the web page image in a second portion of the display of the device according a user input to the device while the user interface image is displayed in the first portion of the display.

2. The method of claim 1, wherein said selectively displaying comprises:

scrolling the web page image in the second portion of the display of the device at exclusive control of the device.

3. The method of claim 2, further comprising:

sending, from the device to the remote server, data indicating scrolling of the web page image in the second portion of the display.

4. The method of claim 2, wherein the first and second portions are within a window of the display of device;

and, the user interface image is displayed fixedly with respect to the window when the web page image is scrolled in the second portion of the display.

5. The method of claim 2, further comprising:

receiving a click at a location in the second portion of the display;

transmitting data indicating the click at the location to the remote server for applying a click on the web page at the remote server.

6. The method of claim 1, wherein the one or more buttons include at least one of:

a home button;

a back button;

a forward button;

a stop button;

a refresh button; and

a go button.

7. The method of claim 1, wherein the user interface image includes a keyboard icon, which when activated causes the device to display a keyboard layout on the display of the device.

8. The method of claim 7, wherein the user interface image includes an address input area for entering an address of the web page.

9. The method of claim 1, wherein the user interface image is stored in the device.

10. The method of claim 9, further comprising:

receiving at the device from the remote server the user interface image during initialization of the device for web accessing.

11. The method of claim 1, wherein the compressed format is loss-less.

12. A device to view Internet content, the device comprising:

means for displaying in a first portion of the display of a device a user interface image including one or more buttons for web browsing;

means for sending a request for a web page from the device to a remote server;

means for receiving at the device from the remote server in a compressed format a web page image, the web page image being rendered at the remote server from the entire web page which the remote server retrieves from the Internet in response to the request, the web page including text and graphics; and

means for selectively displaying a portion of the web page image, under exclusive control of the device, in a second portion of the display of the device according a user input to the device while the user interface image is displayed in the first portion of the display.

13. The device of claim 12, wherein said means for selectively displaying comprises:

means for scrolling the web page image in the second portion of the display of the device at exclusive control of the device.

14. The device of claim 13, further comprising:

means for sending data indicating scrolling of the web page image in the second portion of the display from the device to the remote server.

15. The device of claim 13, wherein the first and second portions are within a window of the display of device;

and, the user interface image is displayed fixedly with respect to the window when the web page image is scrolled in the second portion of the display.

16. The device of claim 13, further comprising:

means for receiving a click at a location in the second portion of the display;

means for transmitting data indicating the click at the location to the remote server for applying a click on the web page at the remote server.

17. The device of claim 12, wherein the one or more buttons include at least one of:

a home button;

a back button;

a forward button;

a stop button;

a refresh button; and

a go button.

18. The device of claim 12, wherein the user interface image includes a keyboard icon, which when activated causes the device to display a keyboard layout on the display of the device.

19. The device of claim 18, wherein the user interface image includes an address input area for entering an address of the web page.

20. The device of claim 12, wherein the user interface image is stored in the device.

21. The device of claim 20, further comprising:

means for receiving at the device from the remote server the user interface image during initialization of the device for web accessing.

22. The device of claim 12, wherein the web page image is compressed using a loss-less method.

23. A machine readable medium containing executable computer program instructions which when executed by a data processing system cause said system to perform a method to view Internet content, the method comprising:

displaying in a first portion of a display of a device a user interface image including one or more buttons for web browsing;

sending a request for a web page from the device to a remote server;

receiving at the device from the remote server in a compressed format a web page image, the web page image being rendered at the remote server from the entire web page which the remote server retrieves from the Internet in response to the request, the web page including text and graphics; and

under exclusive control of the device, selectively displaying a portion of the web page image in a second portion of the display of the device according a user input to the device while the user interface image is displayed in the first portion of the display.

24. The medium of claim 23, wherein said selectively displaying comprises:

scrolling the web page image in the second portion of the display of the device at exclusive control of the device.

25. The medium of claim 24, wherein the method further comprises:

sending, from the device to the remote server, data indicating scrolling of the web page image in the second portion of the display.

26. The medium of claim 24, wherein the first and second portions are within a window of the display of device;

and, the user interface image is displayed fixedly with respect to the window when the web page image is scrolled in the second portion of the display.

27. The medium of claim 24, wherein the method further comprises:

receiving a click at a location in the second portion of the display;
