Coordination Between Media End Devices

1 . An end device that is a first end device, comprising:

a first communications channel for coupling to a source device for the transfer of playback media or call audio; and

a second communications channel for coupling to a second end device, wherein the first end device communicates with the second end device on the second communications channel to exchange control information to influence operation between the second end device and the source device for the transfer of playback media or call audio between the second end device and the source device.

2 . The end device of claim 1 wherein the first end device is one of a vehicle audio system and a wearable audio device, and the second end device is the other of a vehicle audio system and a wearable audio device.

3 . The end device of claim 1 wherein the control information to influence operation between the second end device and the source device is configured to include one or more of answering a call, terminating a call, switching playback media between the first and second end devices, adjusting volume of the playback media, and muting a microphone.

4 . The end device of claim 1 wherein the first end device includes a user configuration setting that indicates whether a user input at the first end device should influence the operation between the second end device and the source device, or that the user input should influence operation between the first end device and the second end device.

5 . The end device of claim 4 wherein the user configuration setting is a persistent setting, which is a user selected default setting, being stored and associated with either of the first or second end device.

6 . The end device of claim 5 further comprising a plurality of user selected default settings, wherein each of the user selected default settings dependent upon at least one of an identified one of a plurality of users, an identified one of a plurality of second end devices, and an identified presence of the one of the plurality of second end devices.

7 . A method of controlling an end device, the method comprising:

establishing, by a first end device, a communications channel to a second end device; and

exchanging control information over the communications channel to influence operation between a source device and the second end device, for the transfer of playback media or call audio between the source device and the second end device.

8 . The method of claim 7 wherein the first end device is one of a vehicle audio system and a wearable audio device, and the second end device is the other of a vehicle audio system and a wearable audio device.

9 . The method of claim 7 wherein the control information to influence operation between the second end device and the source device is configured to include one or more of answering a call, terminating a call, switching playback media between the first and second end devices, adjusting volume of the playback media, and muting a microphone.

10 . The method of claim 7 wherein the first end device includes a user configuration setting that indicates whether a user input at the first end device should influence the operation between the second end device and the source device, or that the user input should influence operation between the first end device and the second end device.

11 . The method of claim 10 wherein the user configuration setting is a persistent setting, which is a user selected default setting, being stored and associated with either of the first or second end device.

12 . The method of claim 11 further comprising a plurality of user selected default settings, wherein each of the user selected default settings dependent upon at least one of an identified one of a plurality of users, an identified one of a plurality of second end devices, and an identified presence of the one of the plurality of second end devices.

13 . A non-transitory computer readable medium having instructions stored thereon that when executed by a suitable processor cause the processor to perform a method comprising:

establishing, by a first end device, a communications channel to a second end device; and

exchanging control information over the communications channel to influence operation between a source device and the second end device, for the transfer of playback media or call audio between the source device and the second end device.

14 . The computer readable medium of claim 13 wherein the first end device is one of a vehicle audio system and a wearable audio device, and the second end device is the other of a vehicle audio system and a wearable audio device.

15 . The computer readable medium of claim 13 wherein the control information to influence operation between the second end device and the source device is configured to include one or more of answering a call, terminating a call, switching playback media between the first and second end devices, adjusting volume of the playback media, and muting a microphone.

16 . The computer readable medium of claim 13 wherein the first end device includes a user configuration setting that indicates whether a user input at the first end device should influence the operation between the second end device and the source device, or that the user input should influence operation between the first end device and the second end device.

17 . The computer readable medium of claim 17 wherein the user configuration setting is a persistent setting, which is a user selected default setting, being stored and associated with either of the first or second end device.

18 . The computer readable medium of claim 18 further comprising a plurality of user selected default settings, wherein each of the user selected default settings dependent upon at least one of an identified one of a plurality of users, an identified one of a plurality of second end devices, and an identified presence of the one of the plurality of second end devices.
