Patent ID: 8831438

Claim:
An apparatus for transmitting visible light communication data, comprising: a common modulation unit configured to generate a modulated signal for transmitting a first visible light communication data; a plurality of individual modulation drivers configured to generate modulated signals for transmitting a plurality of second visible light communication data, based on the modulated signal for transmitting the first visible light communication data output from the common modulation unit; a plurality of arithmetic logic units, with each arithmetic logic unit configured to receive the modulated signal from the common modulation unit, each arithmetic logic unit configured to receive a modulated signal from a respective one of the plurality of individual modulation drivers, and each arithmetic logic unit configured to output a mixed modulation signal; and a plurality of light emitting units, with each of the plurality of light emitting units configured to receive one of the mixed modulated signals from the plurality of arithmetic logic units, respectively, and each of the plurality of light emitting units configured to output a visible light signal representing the first visible light communication data and a respective one of the second visible light communication data.
