Abstract
A transmitting apparatus using visible light communication generates transmission data into a two-dimensional data code according to a predetermined code method between the transmitting apparatus and a receiving apparatus and transmits the two-dimensional data code through a plurality of light emitting diodes (LED) that are arranged in a two-dimensional form. Therefore, the receiving apparatus senses light from a plurality of LEDs as an image using an image sensor, demodulates the image into a two-dimensional data code, decodes the two-dimensional data code using a code book, and restores data.
