Abstract: Provided are a method and apparatus for providing a network switching service to a user equipment.

Abstract: The present disclosure relates to a technology of preparing an anion exchange composite membrane including: a porous polymer support; and a polyfluorene-based anion exchange membrane or a polyfluorene-based anion exchange membrane having a cross-linked structure formed on the support, and applying the same to alkaline fuel cells, water electrolysis, carbon dioxide reduction, metal-air batteries, etc. The polyfluorene-based anion exchange composite membrane including a porous polymer support according to the present disclosure has remarkably improved mechanical properties, dimensional stability, durability, long-term stability, etc.

Abstract: Provided are a method and apparatus for a user equipment, a core network, and a second device to enable bidirectional communication for second devices. The method of the second device may include receiving internet protocol (IP) configuration information for automatically configuring an IP version 6 (IPv6) address of the second device from a core network through a user equipment; generating the IPv6 address using information in the IP configuration information; and transmitting the generated IPv6 address to the core network through the UE.

Abstract: Provided are a method and apparatus for providing a multi virtual local area network service to user equipments.

Abstract: Disclosed is an exoskeleton-type rehabilitation robot system, including: a body part provided on a chair in which a user sits and provided with a robot arm capable of moving left or right based on the user seated on the chair; a conversion part configured to convert a position of the robot arm with respect to the body part; a driving part configured to articulate the robot arm with respect to the body part; and a controller configured to detect a change in a position of the robot arm and control a left or right driving mode of the driving part according to the position of the robot arm. In accordance with such a configuration, the exoskeleton-type rehabilitation robot system of the present invention is provided integrally with a chair, thereby having excellent space utilization. In addition, the user's initial preparation for rehabilitation training is simple, which can improve efficiency.

Abstract: An efficient near video on demand (NVOD) service for various client environments is provided. The NVOD service method for transmitting video data including moving pictures to a plurality of clients in a network includes identifying a relative network bandwidth “m” of a client with respect to a video playout bandwidth, dividing the video data into data segments having different sizes according to the relative network bandwidth “m” and transmitting the data segments to the client through a plurality of channels.

Abstract: An apparatus and a method for separating a digital broadcasting signal from data transmitted using an IP network, transmits an IP packet at wire-speed by performing a comparison of an IP address in a hardware scheme without a special memory when separating Internet data and digital broadcasting data (MPEG-TS) in an IP network-based digital broadcasting signal process unit.

Abstract: An apparatus for controlling a digital transport stream on a digital settop box has independent properties in network construction between a broadcasting HE equipment or VOD server and the settop box, by controlling network interfaces and streams for both an ATM network and an IP network on one xDSL settop box. The apparatus can smoothly cope with network construction by providing services in an ATM mode in an environment requiring high quality of service, and in an IP mode in an environment requiring a low network building cost. When the broadcasting is connected to the ATM network and the VOD is connected to the IP network, the apparatus can provide services without incorporating the networks. In addition, as compared with the ATM mode, the IP mode processes decapsulation and IP routing of an MPEG transport stream packet in a software type, and thus does not require special hardware. That is, both the ATM mode and the IP mode can be controlled in the same hardware construction as the ATM mode.

Abstract: A method for servicing digital broadcasting, capable of defining a control message necessary for servicing digital broadcasting of a SD (Standard) level and a HD (High Definition) level through, a network of, for example, a x Digital Subscriber Line, by directly requesting, at a client, a digital broadcasting server for a session connection, and establishing a session by receiving a confirmation from the digital broadcasting server. Also, a channel change can be requested by directly requesting, at the client, the digital broadcasting server for a channel change, and changing a channel by receiving a confirmation from the digital broadcasting server. Other direct client-server requests and confirmations include a message for checking a status of the client and a session termination.
