INFORMATION SYMBOL TRANSMISSION AND RECEPTION APPARATUS AND A METHOD THEREOF FOR TRANSMITTING DATA AT HIGH SPEED FROM THE VISIBLE LIGHT COMMUNICATIONS SYSTEM

摘要

PURPOSE: An information symbol transmission and reception apparatus and a method thereof for transmitting data at high speed from the visible communications system are provided to maintain color balance in order to keep the color balance in a CCM(Color Code Modulation).;CONSTITUTION: A color coding block(611) determines first coordinate value corresponding to information symbol. A coordinate calculator(613) determines a first color rate corresponding to the first coordinate. The coordinate calculator determines a second co-ordinate value corresponding to the compensation symbol for recompensing the first color rate to the white. The coordinates calculation determines the second color rate corresponding to the second co-ordinate value. A light emitting unit emits visible ray corresponding to the first color rate and the second color rate.;COPYRIGHT KIPO 2010
