Abstract: Disclosed herein are a Visual Light Communication (VLC) method and apparatus using a DMX-512 network. The VLC apparatus includes a DMX signal generation unit and a DMX signal transmission unit. The DMX signal generation unit generates VLC data packets each including a DMX header, fragmentation information, and a data fragment. The DMX signal transmission unit transmits the VLC data packets to an LED lighting apparatus coupled over a DMX-512 network in order to perform VLC.
