Abstract

For wireless peripheral connection, a method establishes a plurality of wireless video connections between at least one computer and a breakout device. At least one of the plurality of wireless video connections is inactive. The method polls the at least one inactive wireless video connection within a specified time interval. The method maintains the at least one inactive wireless video connection in response to the polling.

First claim

What is claimed is:

1. A method comprising:
establishing, by use of a processor, a plurality of wireless video connections between at least one computer and a breakout device, wherein at least one of the plurality of wireless video connections is inactive;
polling the at least one inactive wireless video connection within a specified time interval, wherein the specified time interval TI is calculated as TI=TL−((t−min(AT, PT))/TL where TL is a maximum elapsed time since the at least one inactive wireless video connection was active, t is a current time, AT is a last active timestamp for the at least one inactive wireless video connection, and PT is a last polled timestamp for the at least one inactive wireless video connection; and
maintaining the at least one inactive wireless video connection in response to the polling.

2. The method of claim 1 , the method further comprising activating the inactive wireless video connection.

3. The method of claim 1 , the method further comprising establishing a monitor connection.

4. The method of claim 1 , the method further comprising establishing a peripheral connection.

5. The method of claim 1 , wherein the wireless video connection supports a MIRACAST® protocol.

6. The method of claim 1 , wherein the breakout device is a keyboard, video, mouse (KVM) device.

7. An apparatus comprising:
a processor;
a memory storing code executable by the processor to perform:
establishing a plurality of wireless video connections between at least one computer and a breakout device, wherein at least one of the plurality of wireless video connections is inactive;
polling the at least one inactive wireless video connection within a specified time interval, wherein the specified time interval TI is calculated as TI=TL−(t−min(AT, PT))/TL where TL is a maximum elapsed time since the at least one inactive wireless video connection was active, t is a current time, AT is a last active timestamp for the at least one inactive wireless video connection, and PT is a last polled timestamp for the at least one inactive wireless video connection; and
maintaining the at least one inactive wireless video connection in response to the polling.

8. The apparatus of claim 7 , the code further executable by the processor to perform activating the inactive wireless video connection.

9. The apparatus of claim 7 , the code further executable by the processor to perform establishing a monitor connection.

10. The apparatus of claim 7 , the code further executable by the processor to perform establishing a peripheral connection.

11. The apparatus of claim 7 , wherein the wireless video connection supports a MIRACAST® protocol.

12. The apparatus of claim 7 , wherein the breakout device is a keyboard, video, mouse (KVM) device.

13. A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
establishing a plurality of wireless video connections between at least one computer and a breakout device, wherein at least one of the plurality of wireless video connections is inactive;
polling the at least one inactive wireless video connection within a specified time interval, wherein the specified time interval TI is calculated as TI=TL−(t−min(AT, PT))/TL where TL is a maximum elapsed time since the at least one inactive wireless video connection was active, t is a current time, AT is a last active timestamp for the at least one inactive wireless video connection, and PT is a last polled timestamp for the at least one inactive wireless video connection; and
maintaining the at least one inactive wireless video connection in response to the polling.

14. The program product of claim 13 , the code further executable by the processor to perform activating the inactive wireless video connection.

15. The program product of claim 13 , the code further executable by the processor to perform establishing a monitor connection.

16. The program product of claim 13 , the code further executable by the processor to perform establishing a peripheral connection.

17. The program product of claim 13 , wherein the wireless video connection supports a MIRACAST® protocol.
