Abstract

A first system may receive a view from a second system. The first system may establish a direct wireless communication link with the second system that does not connect through any intermediate system between the first system and the second system. Through the direct wireless communication link, the first system sends a view sharing request to the second system. The view sharing request may specify a view that is displayed by the second system and not the first system. The first system may receive view information corresponding to the view and display the view according to the received view information.

Claims

1. A method comprising:

in a first system;

establishing a direct wireless communication link with a second system in which the direct wireless communication link does not connect through any intermediate system between the first system and the second system;

sending, through the direct wireless communication link, a view sharing request to the second system, where the view sharing request specifies a view displayed by the second system that is not presently displayed by the first system;

receiving, through the direct wireless communication link, view information corresponding to the view displayed by the second system and specified by the view sharing request;

displaying, with the first system, the view according to the view information received from the second system;

receiving, through the direct wireless communication link, view adjustment information specifying a change in view characteristics of the displayed view; and

adjusting characteristics of the displayed view in the first system according to the view adjustment information without adjusting how the view is displayed in the second system.

2. The method of claim 1, comprising:

establishing multiple communication links with the second system, including the direct wireless communication link.

3. The method of claim 2, comprising:

receiving, through the multiple communication links, the view information corresponding to the view displayed by the second system.

4. The method of claim 3, where establishing multiple communication links comprises:

establishing a secure communication link with the second system; and

where receiving the view information comprises;

receiving selected sensitive information of the view information through the secure communication link.

5. The method of claim 4, where receiving the view information further comprises:

receiving non-sensitive information of the view information through the secure communication link.

6. The method of claim 1, where establishing a direct wireless communication link comprises:

establishing a direct Bluetooth communication link with the second system.

7. The method of claim 1, where establishing a direct wireless communication link comprises:

establishing a direct 802.11 wireless communication link with the second system.

8. The method of claim 1, wherein adjusting characteristics of the displayed view in the first system comprises adjusting the view in the first system without adjusting how the view is displayed in the second system.

9. The method of claim 1 wherein displaying the view according to the view information comprises displaying a window including the view and wherein receiving the view adjustment information comprises receiving window size adjustment information and wherein adjusting characteristics of the displayed view comprises changing window size of the window including the view.

10. A device comprising:

a user interface;

a communication interface; and

view sharing circuitry in communication with the user interface and the communication interface, the view sharing circuitry operable to;

establish a wireless communication link with a second device through the communication interface;

send, through the wireless communication link, a video sharing request to the second device, where the video sharing request specifies a video displayed by the second device that is not presently displayed through the user interface;

receive, through the wireless communication link, video information corresponding to the video displayed by a second system and specified by the video sharing request;

display, through the user interface, the video according to the video information received from the second device while the second device displays the video at the same time;

receive, through the wireless communication link, display adjustment information specifying a change in view characteristics of the displayed video; and

adjust the displayed video in the user interface according to the display adjustment information without adjusting how the view is displayed in the second system.

11. The device of claim 10, where the view sharing circuitry is operable to establish, through the communication interface, multiple communication links with the second device, including the wireless communication link.

12. The device of claim 11, where the view sharing circuitry is operable to receive, through the multiple communication links, the video information corresponding to the video displayed by the second device.

13. The device of claim 12, where:

the multiple communication links include a secure communication link with the second device; and

where the video information comprises selected sensitive information of the video information sent through the secure link.

14. The device of claim 13, where the video information comprises non-sensitive information of the video information sent through the secure communication link.

15. The device of claim 10, where the wireless communication link comprises a Bluetooth communication link.

16. The device of claim 10, where the wireless communication link comprises an 802.11 wireless communication link.

17. The device of claim 10, wherein the view sharing circuitry is operable to adjust the displayed video in a first system without adjusting how the displayed video is displayed in the second system.

18. The device of claim 10, wherein displaying the video according to the view information comprises displaying, through the user interface, a window including the video and wherein receiving the display adjustment information comprises receiving window size adjustment information and wherein adjusting the displayed video comprises changing window size of the window including the video on the user interface.

19. A product comprising:

a non-transitory machine readable medium; and

logic stored on the non-transitory machine readable medium, that when executed by a processor of a first system, causes the first system to;

establish a wireless communication link with a second system different from the first system;

send a view sharing request to the second system, where the view sharing request specifies a view displayed by the second system that is not presently displayed by a first system;

receive, through the wireless communication link, view information corresponding to the view displayed by the second system and specified by the view sharing request;

display the view according to the view information received from the second system;

receive a display adjustment specifying a change in how to display the view on the first system; and

adjust the display of the view in the first system according to the display adjustment without adjusting how the view is displayed in the second system.

20. The product of claim 19, where the display adjustment specifies changing a window size of a window displaying the view.

21. The product of claim 19, where the display adjustment specifies minimizing the display of the view to an icon.

22. The product of claim 19, where the processor executable instructions cause the first system to establish multiple communication links with the second system, including the wireless communication link.

23. The product of claim 22, where the processor executable instructions cause the first system to receive, through the multiple communication links, the view information corresponding to the view displayed by the second system.

24. The product of claim 19, where the processor executable instructions cause the first system to add a secure communication capability to the wireless communication link.
