摘要： A user equipment and an advertisement service server for a bidirectional personalized advertisement, and a bidirectional personalized advertisement method are provided. The UE receives user setting information and advertisement meta-information from the advertisement service server, stores the received user setting information and advertisement meta-information, searches for advertisement contents corresponding to the user setting information from the stored advertisement meta-information and selects the found advertisement contents when an advertisement event occurs, and displays the selected advertisement contents. Accordingly, the dependence of an online advertisement service on a particular media service can be prevented.

摘要： A fragmentation repetition detection apparatus (410) for detecting an IP fragmentation repetition which may occur in a multicast or unicast environment is provided. The fragmentation repetition detection apparatus (410) includes a packet capturing unit (411) which captures a received packet, a fragmentation repetition detector which detects whether or not the captured packet is a packet which is repetitively fragmented, and a path maximum transmission unit (PMTU) transmitter (414) which transmits PMTU information acquired by the fragmentation repetition detector (412) to a server which transmits the packet when the captured packet is a packet which is repetitively fragmented. Since a packet is transmitted by readjusting a PMTU, a fragmentation of an IP packet can be prevented.

摘要： Disclosed is a system of transporting multimedia based on network, and more particularly, to an apparatus for inserting, transporting and extracting a timestamp through a network protocol. A network timestamp is transported without changing a preset transport standard such as a UDP, an RTP and a MPEG-2 standard by adding a packet having a timestamp, which is used to compensate for network jitter and used for synchronization, to a packet stream transported through a UDP or an RTP.

摘要： A burst mode optical repeater is provided. The burst mode optical repeater receives optical signals, which are transmitted from a plurality of optical network units (ONUs) in a passive optical network (PON) to a central office using a time division multiplexing access (TDMA) method, and relays the received optical signals using an optical-electrical-optical (OEO) method. Since the burst mode optical repeater can be installed anywhere between an optical line terminal (OLT) and the ONUs, the number of subscribers and transmission range that can be supported by a corresponding network can be increased.
