Abstract
The invention is directed at a remote-control device for controlling one or more user devices, comprising a directional optical sensor for receiving one or more optical signals from the user devices. Each optical signal encodes a device identifier by high and low signal states in periods having granulated lengths. Each granulated length is an integer number of clock periods of a transmitter clock. The transmitter clock has a clock ratio to the predetermined receiver clock, the clock ratio being a number larger than one. At least one granulated length is longer than an integer number of clock periods of the predetermined receiver clock by a fraction of the clock period of the predetermined receiver clock, which granulated length may be detected by an asynchronous receiver clock and a detection range having only two values.
