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 transmitting data more effectively, and more particularly, a method of transmitting data to a group comprising a plurality of reception stations that receive the same data from a transmission station when the stations communicate the data in a power line communication (PLC) network, and an apparatus to do the same. According to the method, a transmission station transmits data to a group including a plurality of reception stations that receive the same data at a time, to prevent a channel bandwidth from being wasted, and to prevent a station that does not desire to receive the data from receiving the data.

摘要： A method and apparatus for packet aggregation in a power line communication network (PLC) are provided. The method of aggregating packets includes: by performing a PLC channel estimation, determining whether or not a channel condition is good; if the channel condition is good, determining whether or not the data desired to be transmitted is suitable for packet aggregation according to the type of data; and if the channel condition is good and the data desired to be transmitted is suitable for the packet aggregation, aggregating packets of the data desired to be transmitted. Since a decision on whether or not to aggregate packets is determined according to a channel condition at a physical level and the type of data at an application level, packet aggregation can be performed in appropriate response to the frequently changing condition of a channel and the characteristic of the data desired to be transmitted.

摘要： Provided are a method of providing media contents in a wired/wireless network environment and an apparatus using the same. The method includes: detecting a start point of media contents included in multimedia contents from the multimedia contents; and extracting a part of media contents based on the detected start point. Thus, the part of media contents can be provided to a digital media client in real time transcoding in which it is difficult to calculate the far end point of media contents.
