A portable electronic device with a touch-sensitive display (such as a cellular telephone) provides a wireless remote control for an entertainment device (such as a consumer-electronic device). After providing, to an audio/video (A/V) hub, user-interface activity information that specifies a change in a state of the entertainment device, the portable electronic device receives device-state information that specifies a current state of the entertainment device from the A/V hub. Until the device-state information indicates that the change in the state has occurred, the portable electronic device: provides: the user-interface activity information to the A/V hub; and receives, from the A/V hub, additional device-state information indicating whether the change in the state has occurred. In addition, the portable electronic device may provide feedback (such as a visual indicator or sensory feedback) to a user about the status of the change in the state. |

1. A portable electronic device, comprising:
a touch-sensitive display; an antenna; an interface circuit, coupled to the antenna, configured to communicate with an audio/video (A/V) hub; and a control circuit, coupled to the touch-sensitive display and the interface circuit, configured to:
receive user-interface activity information specifying activation of a virtual command icon in a user interface displayed on the touch-sensitive display, wherein the activation of the virtual command icon specifies a change in a state of an entertainment device;provide, via the interface circuit, the user-interface activity information to the A/V hub;receive, via the interface circuit, device-state information from the A/V hub indicating whether the change in the state of the entertainment device has occurred; andwhen the change in the state of the entertainment device has not occurred, perform, until the change in the state of the entertainment device has occurred, operations of:
providing, via the interface circuit, the user-interface activity information to the A/V hub; andreceiving, via the interface circuit, additional device-state information from the A/V hub indicating whether the change in the state of the entertainment device has occurred. |
