Abstract
A first modulation section performs low-speed digital modulation of first data. A second modulation section performs high-speed digital modulation of second data. A first light transmitting section alternately emits and quenches visible light in accordance with an output signal of the first modulation section to transmit a visible light signal which conveys the first data. A second light transmitting section changes an intensity of the infrared light in accordance with an output signal of the second modulation section to transmit an infrared light signal, which conveys the second data, in parallel with the visible light signal.
