Pushbits for semi-synchronized pointing

摘要

A method of selecting a light source among a plurality of light sources by means of a remote controller includes the remote controller: instructing, by omnidirectional transmission, the light sources to each transmit a directional signal comprising a code, which is unique for each light source; —receiving the directional signals from the light sources; and selecting one of the light sources on basis of the received directional signals. Furthermore, the method includes: generating, remotely of the light sources, codes to be transmitted by the light sources; and—the remote controller instructing each one of the light sources which one of the remotely determined codes to transmit.

1. A method of selecting a light source among a plurality of light sources by a remote controller, comprising:
the remote controller instructing, by omnidirectional transmission, the plurality of light sources to each transmit a directional signal comprising at least a fraction of a code, which is unique for each light source, wherein each code consists of a sequence of one or more code symbols; generating, remotely of the plurality of light sources, the codes to be transmitted by the plurality of light sources; the remote controller instructing each one of the plurality of light sources which one of the remotely determined codes to transmit, the instructing comprising instructing the plurality of light sources to transmit the code symbols at different times, one code symbol at a time, and which code symbol to transmit at what time; the remote controller receiving the directional signals from the plurality of light sources; and the remote controller performing a selection procedure for selecting one of the plurality of light sources on the basis of the received directional signals, wherein after having selected one light source, instructing the plurality of light sources by the remote controller to return to the settings they had prior to the first code symbol broadcast.
