Abstract: Disclosed herein is a method and apparatus that are capable of retransmitting lost RDM packets in RDM protocol to control various devices connected to DMX512 network. The method recovers an error in a remote controller for remotely controlling devices connected to DMX512 network via RDM protocol based on the DMX512 network. A RDM packet to be transmitted to each device is stored in a buffer, and then the RDM packet is transmitted to the device. A preset period of time is waited for so as to receive a response packet from the device. If the response packet is received within the preset period of time, a transaction number of the response packet is checked, and a sequence of the response packet with respect to previously arrived response packets is determined The corresponding RDM packet is retransmitted depending on a result of determination of the sequence.

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.
