20090196622 | Reconnection method in peripheral interface using visible light communication - A reconnection method and device for a peripheral interface using VLC provide a protocol for when a communication link between a primary device and a secondary device is disconnected. The primary device generates an R-XID message including reconnection information and a warning indication signal indicating the disconnection. The secondary device aligns the communication link with the primary device using the warning indication signal, receives the R-XID message from the primary device by the secondary device, and transmits an R-XID response message for the R-XID message to the primary device. | 08-06-2009 |
20110002695 | APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA USING VISIBLE LIGHT COMMUNICATION - Provided is an apparatus and method for transmitting and receiving data in a visible light communication system, the apparatus including a visible light communication (VLC) transceiver for converting a visible light signal received from a counterpart into an electrical signal and outputting the electrical signal, by using a light receiving device during a reception operation, and converting an electrical signal containing information into a visible light signal and transmitting the visible light signal to the counterpart, by using a light emitting device during a transmission operation, a VLC controller comprising a visible frame engine (VFE) for generating a visible frame and outputting the visible frame to the VLC transceiver, in which the VFE generates the visible frame for transmission to a counterpart during non-transmission of respective frames for communication at a sender and a receiver in order to provide visibility to a communication link, and a host controller for controlling the VLC controller and transmitting and receiving data to and from the VLC controller. | 01-06-2011 |
