Abstract: An apparatus and method for determining the location of a terminal are disclosed herein. The apparatus includes a reception unit, an initiation unit, a selection unit, and a correction unit. The reception unit receives the location identifications (IDs) of one or more illumination lights. The initiation unit initiates the location coordinates of a receiving terminal to the coordinates of an illumination light corresponding to the most frequently received location identification (ID). The selection unit selects the coordinates of an illumination light corresponding to the second-most frequently received location ID. The correction unit calculates the reception ratio of reception from the coordinates of the initiated illumination light to reception from the coordinates of the selected illumination light, and then corrects the coordinates of the receiving terminal based on the calculated reception ratio.

Abstract: The present invention relates to a method of processing a Digital Multiplex (DMX)-Visible Light Communication (VLC) address and a device using the method. In the method of processing a DMX-VLC address, a DMX-512 packet is received. It is determined whether the DMX-512 packet includes dimming data by using a start code of the DMX-512 packet. Lighting data is processed using an address recorded in a DMX-512 address field of a DMX-VLC address included in the DMX-512 packet if it is determined that the DMX-512 packet includes the dimming data. Non-lighting data is processed using an address recorded in a DMX-VLC extended address field of the DMX-VLC address if it is determined that the DMX-512 packet does not include dimming data.
