Abstract

A media device and docking device used in a home entertainment system are described. The entertainment system 100 includes a docking device operating in several modes allowing the media device to be charged by the docking device and allowing the docking device to be used for conveying a signal to the media device from the docking device when the media device is connected to the docking station and conveying the signal through the docking device to another media device when the first media device is not connected to the docking device.

Claims

1. A method for conveying a signal between multiple media devices, comprising the steps of:

conveying said signal to a first media device from a docking station when said first media device is connected to said docking station; and

conveying said signal through said docking station to a second media device when said first media device is not connected to said docking station.

2. The method set forth in claim 1, wherein said signal includes at least one of an analog audio signal and an analog video signal.

3. The method set forth in claim 1, further comprising the step of conveying (780) said signal through said docking station to said second media device when said first media device is connected to said docking station and not active.

4. The method set forth in claim 3, wherein the step of conveying said signal through said docking station to said second media device when said first media device is connected to said docking station and not active further includes conveying said signal through said docking station to said second media device when said docking station is charging said first media device.

5. The method set forth in claim 1, wherein the step of conveying said signal to said first media device further includes conveying said signal to a first media device from said docking station when said first media device is active.

6. The method set forth in claim 1, wherein the step of conveying said signal to said first media device further includes conveying said signal to a first media device from said docking station when said first media device is powered on.

7. The method set forth in claim 1, wherein the step of conveying said signal to said first media device is responsive to said first media device.

8. A docking device, said docking device comprising:

a first interface for connecting said docking device to a portable electronic device, said first interface permitting said docking device to charge said portable electronic device and to route signals to and from said portable electronic device;

a second interface for connecting said docking device to a first media device, said second interface permitting said docking device to route said signals from said first media device;

a third interface for connecting said docking device to a second media device, said third interface permitting said docking device to route signals to said second media device; and

a switch for switchably connecting said second interface to said third interface when said portable electronic device is not connected to said docking device and for switchably connecting said first interface to said second interface when said portable electronic device is connected to said docking device.

9. The docking device of claim 8, wherein said signals comprise an analog audio signal and an analog video signal.

10. The docking device of claim 9, wherein said second interface further comprises separate signal paths for said analog audio signal and said video signal.

11. The docking device of claim 9, wherein said third interface further comprises separate signal paths for said analog audio signal and said video signal.

12. The docking device of claim 8, wherein said switch is responsive to said portable electronic device when said portable electronic device is connected to said docking device.

13. The docking device of claim 8, wherein said switch switchably connects said first interface to said second interface when said portable electronic device is connected to said docking device and said portable electronic device is powered on.

14. The docking device of claim 8, wherein said switch switchably connects said first interface to said third interface when said portable electronic device is connected to said docking device and said portable electronic device is powered on.

15. The docking device of claim 8, wherein said switch switchably connects said second interface to said third interface when said portable electronic device when said portable electronic device is connected to said docking device and said portable electronic device is powered off.

16. The docking device of claim 8 wherein said docking device is for charging a portable electronic device.

17. The docking device of claim 16, wherein said switch switchably connects said second interface to said third interface said when said docking device is charging said portable electronic device.

18. The docking device of claim 8, wherein said switch switchably connects said second interface to said third interface when said docking device is powered on.

19. The docking device of claim 8, wherein said first interface communicates a control signal from said portable electronic device to said switch.

20. The docking device of claim 8, wherein said portable electronic device is a portable media device for displaying video and audio content.

21. An apparatus for conveying audio and video signals to media devices, comprising:

a means for conveying said audio and video signals to a first media device using a docking station when said first media device is connected to said docking station; and

a means for conveying said audio and video signals through said docking station to a second media device when said first media device is not connected to said docking station.

22. The apparatus of claim 21 further comprising a means for conveying said signal through said docking station to said second media device when said first media device is connected to said docking station and not active.

23. The apparatus of claim 22 wherein said means for conveying said signal through said docking station to said second media device when said first media device is connected to said docking station and not active further includes a means for conveying said signal through said docking station to said second media device when said docking station is charging said first media device.

24. The apparatus of claim 21 wherein said means for conveying said signal to said first media device further includes a means for conveying said signal to said first media device from said docking station when said first media device is powered on.

25. The apparatus of claim 21 wherein said means for conveying said signal to said first media device is responsive to said first media device.
