Abstract
A system with which any abnormality can be easily found is provided. A system includes: a first modulator that generates a control signal and modulates an input signal in accordance with the generated control signal, to control luminance of a first light source that emits light according to the modulated input signal, the first modulator outputting the control signal; a second modulator that acquires the control signal output from the first modulator and modulates an input signal in accordance with the control signal, to control luminance of a second light source that emits light according to the modulated input signal, the second modulator outputting the control signal. The first modulator generates, as a light ID signal, a control signal for transmitting a visible light signal by luminance variations of the first light source, and acquires a light information signal being the control signal output from the second modulator.
