    摘要： A live content management method, a source device, and a sink device are provided. The live content management method includes storing live content in a storage unit of a source device if the transmission of the live content from the source device to a sink device is temporarily stopped. The live content management method may also include transmitting the live content stored in the storage unit of the source device to the sink device and then transmitting live content currently being broadcasted to the sink device via the storage unit of the source device, when receiving a request for resuming the transmission of the live content stored in the storage unit of the source device before a time-out for a command to stop the transmission of the live content stored in the storage unit of the source device. Accordingly, it is possible to provide various data transmission scenarios for a home network environment by efficiently managing live content even when the transmission of the live content via a home network has been temporarily stopped.

    摘要： A method of negotiating channel sharing between adjacent cells when there are a plurality of cells in a power line communication (PLC) network. The method includes attempting to negotiate the channel sharing during a minimum contention access period (CAP) which starts after a maximum beacon period ends and ends before a CAP of each PLC cell ends, wherein the maximum beacon period indicates a maximum size that a beacon frame in a super-frame transmitted from a coordinator of each PLC cell can have. When an attempt to negotiate the channel sharing is made using this method, interference does not occur during channel sharing negotiation, and effective channel sharing can be achieved, thereby eliminating interference between adjacent cells.

    摘要： A method of distributing group identifiers IDs (GIDs) in a power line communication (PLC) network, a method of receiving the GIDs, an authentication apparatus, and a PLC apparatus are provided. The authentication apparatus includes: an authentication mode storing unit which stores an authentication mode having a value including one of an authentication authorized mode and an authentication unauthorized mode; a GID request receiver which receives a GID request message from a PLC apparatus; and a GID transmitter which, if the authentication mode is the authentication authorized mode, transmits a GID corresponding to the PLC apparatus to the PLC apparatus. Authentication is realized in a PLC media access control layer distributing the GIDs between a PLC apparatus and an authentication apparatus, so manually inputting a GID into the PLC apparatus is not necessary. Further, the GIDs are distributed via the authentication apparatus, thereby centrally managing the GIDs.

    摘要： Provided is an apparatus and method of displaying power line communication channel information. The apparatus for displaying power line communication (PLC) channel information includes a channel information determining unit which performs PLC channel estimation and determines channel information including a bandwidth which is available for a user in a power line communication network; and a channel information displaying unit which displays the channel information to the user. Since channel information is determined through channel estimation and displayed to a user, it is possible to easily check whether a channel can be used before installing a power line communication (PLC) device. In an application, information on kinds of a service which can be selected by the user or expected quality of the service can be previously checked. Accordingly, the user can know whether the communication can be performed, without installing a communication device or executing a communication application which requires much time and effort. Accordingly, it is possible to reduce time and effort necessary for finding an adequate communication point.
