propagating, from the first device to a third device, the address of the first device in association with the indication that the first device is the master for the remote control command type;

receiving, at the third device, another remote control command from another remote control;

identifying, at the third device, a command type of the another remote control command;

responsive the command type of the another remote control command being remote control command type that the first device is the master for, forwarding the another remote control command using the address of the first device.

6. The method of claim 1 , further comprising:

propagating, from the first device to the second device, an indication that the first device is no longer the master for the remote control command type.

7. The method of claim 6 , further comprising:

propagating, from the second device to the third device, the indication that the first device is no longer the master for the remote control command type responsive to receiving the indication from the first device.

8. The method of claim 1 , wherein the indication is an indication that the first device is a master for one of graphical user interface (GUI) remote control commands, playback control commands, or audio control commands.

9. The method of claim 1 , further comprising:

modifying, at the first device a multimedia output of the first device based on the remote control command received from the second device responsive to the received remote control command being the remote control command type that the first device is master for.

10. A first device, comprising:

an interface circuit to communicate with a second device via a multimedia link;

another interface circuit to communicate with a third device via another multimedia link; and

a memory storing instructions, the instructions when executed by a processor cause the processor to:

transmit, to the second device, an address of the first device in association with an indication that the first device is master of a remote control command type;

transmit, to the third device, the address of the first device and the indication that the first device is master of the remote control command type;

receive, from the second device, a remote control command that is forwarded based on the address;

modify a multimedia output of the first device based on the received remote control command responsive to the received remote control command being the remote control command type that the first device is master for;

receive, from the third device, another remote control command that is forwarded based on the address; and

modify the multimedia output of the first device based on the received another remote control command responsive to the received another remote control command being the remote control command type that the first device is master for.

11. The first device of claim 10 , the instructions further comprising instructions to:

transmit, to the second device and the third device, an indication that the first device is no longer the master of the remote control command type.

12. The first device of claim 10 , wherein the indication is an indication that the first device is a master for one of graphical user interface (GUI) remote control commands, playback control commands, or audio control commands.

13. A first device, comprising:

an interface circuit to communicate with a second device via a multimedia link;

another interface circuit to communicate with a third device via another multimedia link; and

a memory storing instructions, the instructions when executed by a processor cause the processor to:

transmit, to the second device, an address of the first device in association with an indication that the first device is master of a remote control command type;

receive, from the second device, a remote control command that is forwarded based on the address;

modify a multimedia output of the first device based on the received remote control command responsive to the received remote control command being the remote control command type that the first device is master for;

receive, from the third device, an address of the third device in association with an indication that the third device is master of another remote control command type;

receive, from the second device, another remote control command;

determine if the another remote control command is the remote control command type that the third device is the master for; and

forward the another remote control command to the third device using the address of the third device responsive to the another remote control command being the remote control command type that the third device is the master for.

14. A first device, comprising:

an interface circuit to communicate with a second device via a multimedia link;

a wireless receiver to receive a remote control command from a remote control; and

a memory storing instructions, the instructions when executed by a processor cause the processor to:

receive, from the second device, an address of the second device in association with an indication that the second device is master of a remote control command type;

store, at the first device, control master information associating the address of the second device with the remote control command type that the second device is master for;

identify at the first device, a type of the remote control command received from the remote control; and

responsive to the control master information indicating that the type of the received remote control command is the remote control command type that the second device is master for, forward by the first device the received remote control command using the address of the second device stored in the control master information.

15. The first device of claim 14 , the instructions further comprising instructions to:

responsive to the type of the received remote control command being a remote control command type that the first device is master for, modify a multimedia output of the first device.

16. The first device of claim 14 , wherein the indication is an indication that the first device is a master for one of graphical user interface (GUI) remote control commands, playback control commands, or audio control commands.

17. The first device of claim 14 , the further comprising:

another interface circuit to communicate with a third device via another multimedia link; and

the instructions further comprising instructions to:

propagate, responsive to receiving the indication from the second device, the address of the second device in association with the indication that the second device is master of the remote control command type.

18. The first device of claim 17 , the instructions further comprising instructions to:

receive, from the third device, another remote control command and the address of the second device;

identify a type of the another remote control command; and

responsive to the type of the another received remote control command being the remote control command type that the second device is master for, forward the received another remote control command using the address of the second device.

19. The first device of claim 14 , the instructions further comprising instructions to:

receive, from the second device, an indication that the second device is no longer the master for the remote control command type.
