Abstract

Methods and apparatus relating to wireless remote control are described. A communications device, such as a cell phone with peer to peer signaling capability, supports remote control functionality. The same communications device can be used as a universal wireless remote controller for a plurality of different remotely controllable devices including, e.g., a television, a DVD player, a light switch, a garage door opener, etc. The communications device monitors for and detects peer to peer signals from remotely controllable devices in its local vicinity. The communications device maintains a list of remotely controllable devices in its vicinity based on the detected peer to peer signals. The universal remote control user interface is configured in accordance with the maintained list. The universal remote controller provides a user interface which varies based on the device to be controlled.

Claims

receiving a first wireless signal from a remotely controllable device;

adding said remotely controllable device to a list of controllable devices in wireless communications range of said communications device;

initializing a lifetime value for said remotely controllable device;

enabling control of the remotely controllable device via a user interface on the communications device;

determining, based on said lifetime value, whether or not to remove the remotely controllable device from said list, said determining including comparing the lifetime value for said remotely controllable device to a drop threshold; and

re-initializing the lifetime value for said remotely controllable device in response to receiving a second wireless signal from said remotely controllable device.

2. The method of claim 1,

wherein receiving said first wireless signal from said remotely controllable device includes receiving a peer discovery signal.

3. The method of claim 1, wherein enabling control of the remotely controllable device includes:

displaying user selectable device control options available to the user of said communications device.

4. The method of claim 3, further comprising:

monitoring for user selection of one of said displayed user selectable device control options; and

in response to detecting selection of one of said displayed user selectable device control options, transmitting a signal to said remotely controllable device used to control the remotely controllable device to implement the selected option.

5. The method of claim 4, further comprising:

accessing stored information indicating the characteristics of the control signal to be transmitted to control the remotely controllable device to implement the selected option.

6. The method of claim 1, wherein enabling control of the remotely controllable device includes:

displaying a user selectable icon corresponding to the remotely controllable device.

7. The method of claim 1, further comprising:

retrieving from a remote location via a network connection, in response to said received first wireless signal from said remotely controllable device, a set of control information corresponding to said remotely controllable device, said set of control information including control signal information corresponding to said remotely controllable device; and

determining from a device identifier communicated by said first received wireless signal which of a plurality of device control options to present to the user of the communications device.

8. A communications device, comprising:

means for receiving a first wireless signal from a remotely controllable device;

means for adding said remotely controllable device to a list of controllable devices in wireless communications range of said communications device;
