Classification: CPC G  H | IPC G  H

Claim 8:
9. A visible light communication (VLC) controller to provide VLC communication capabilities in a controlled device, the controller comprising:
processor circuitry to:
periodically cycle at least one visible light output device through a plurality of sequential operating cycles, each of the plurality of sequential operating cycles including an illuminated portion and a non-illuminated portion based on a timing signal provided by timing circuitry;
synchronize the non-illuminated cycle portion with one or more other VLC controllers using the timing signal;
generate a message responsive to receipt of a command from a remote-control device via communicatively coupled interface circuitry;
communicate the message to the at least one other VLC controller using VLC, the message communicated during the non-illuminated cycle portion of a first of the plurality of operating cycles; and
communicate an acknowledgement message to the remote-control device responsive to receipt of the command from the remote-control device.
