    • A client device and a method for streaming contents, and a computer-readable recording medium storing a program thereof are provided to select a server in considering or all bandwidths when a user selects a content item in a list by displaying the list of all contents shared in a P2P and client/server mode playable irrespective of a sharing mode. A P2P middleware(220) supports the P2P mode and a client-server middleware(230) supports the client-server mode. An adaptation manager(240) provides the content list, determines a source device with a node or the server sharing the selected contents, and determines the streaming mode with the mode sharing the contents in the source device. An application part(260) performs control for receiving the contents from the source device through the middleware and a transfer layer corresponding to the determining streaming mode. A storing part(250) stores the received contents. If a content request is received from an external device, the application part performs the control for reading the requested contents from the storing part and transmitting the read contents through the P2P middleware.

    • A method for having negotiation for sharing a TDMA(Time Division Multiple Access) channel on a PLC(Power Line Communication) network is provided to share channels effectively and to eliminate interference of adjacent cells by preventing the interference from occurring in the process of the negotiation for sharing channels. A method for having negotiation for sharing a TDMA(Time Division Multiple Access) channel on a PLC(Power Line Communication) network includes a step of attempting to make negotiation for sharing channels via a minimum CAP(Contention Access Period) which starts at a point after a maximum beacon period and ends at a point before a CAP of each PLC cell. The maximum beacon period expresses a maximum size which a beacon frame of a super frame transmitted from a coordinator within each PLC cell can have. Each station which attempts to make negotiation for sharing channels registers a negotiation target stations at a DST(Detected Station Table) or a DCT(Detected Cell Table).
    • 提供一种用于在PLC(电力线通信)网络上共享TDMA(时分多址)信道的协商的方法,以有效地共享信道,并通过防止在协商过程中发生干扰来消除相邻小区的干扰 用于共享频道。 一种用于在PLC(电力线通信)网络上共享TDMA(时分多址)信道的协商的方法包括尝试通过从一点开始的最小CAP(竞争接入周期)进行共享信道的协商的步骤 在最大信标周期之后,并在每个PLC单元的CAP之前的一个点结束。 最大信标周期表示从每个PLC小区内的协调器发送的超帧的信标帧的最大大小。 尝试进行共享通道协商的每个站在DST(检测站台)或DCT(检测到的小区表)上登记协商目标站。

    • A PLC(Power Line Communication) channel information display device and a method therefor are provided to determine channel information through channel estimation to display the determined information to a user, thereby simply testing whether a channel is usable before a PLC device is installed. A channel information determiner(110) determines channel information which contains bandwidths usable by a user in the current PLC network through PLC channel estimation. A channel information display(120) displays the channel information to the user. The determiner comprises as follows. A data frame transmission time determiner(112) determines data frame transmission time required for transmitting overall data frames through the channel estimation. A hierarchical bandwidth calculator(114) divides size of data to be transmitted at each transmission hierarchy by the data frame transmission time, and calculates the bandwidths usable by the user.
