Abstract:
PURPOSE: A network management device using a dynamic updating of an MIB(Management Information Base) bundle of an SNMP(Simple Network Management Protocol) agent and a method thereof are provided to receive an MIB bundle from a network management server to dynamically collect new management information, and to inform the network management server of a network failure, thereby efficiently managing a network. CONSTITUTION: A network management server(20) obtains authentication for a transmission right of an MIB bundle(14) from a remote SNMP agent(11), transmits the MIB bundle(14) for dynamically collecting new management information to the SNMP agent(11), receives management information on a network from the SNMP agent(11), and manages the network. A network device(10) performs an authentication process for the transmission right of the MIB bundle(14), dynamically updates the MIB bundle(14), dynamically collects the management information, and transmits the collected information to the network management server(20).

PURPOSE: A device for managing and controlling a UPnP(Universal Plug and Play) device of a home network by an external Internet and a method therefor are provided to supply the same environment as the home network from an external Internet network, thereby controlling and managing devices of the home network at any time, place as reducing time and cost. CONSTITUTION: A client(100) comprises as follows. A stub(102) supplies the same API(Application Program Interface) as a UPnP API to a user, manages information of UPnP devices(150), and processes a device control command of the user. A push client(103) transmits the device control command to a UPnP proxy server(130), and transmits an event message transmitted from the UPnP proxy server(130) to the stub(102). The UPnP proxy server(130) comprises as follows. A bridge(132) manages the UPnP devices(150) of a home network(140), receives the device control command, and controls the UPnP devices(150). An agent(131) receives the device control command to transmit the command to the bridge(132), and transmits a command result and the event message to the client(100).
Abstract:
The present invention relates to a method capable of playing AV content by forming a virtual AV device by combining a video renderer, an audio renderer, and a media server supporting local device middleware. In forming the virtual AV device, a device to play video content and a device to play audio content are designated separately when playing AV content, and a user can play AV content by forming various virtual AV devices. Also, media servers, video renderers, and audio renders supporting a previous local device middleware can be used without changing them to support this kind of services.

Abstract:
PURPOSE: A multi-screen based multi-dimensional game service method and a device thereof are provided to offer a game in a home network without the high specification hardware of a user terminal. CONSTITUTION: A home server (110) connected to a home network (120) executes multi-dimensional game rendering, encoding, and streaming function for a multi-screen service. A home server (110) shares data by using view points of other users and provides a streaming service after applying the resolution of a user terminal (130) to the data.

Abstract:
PURPOSE: An UPnP(Universal Plug and Play) PLC(Power Line Communication) adapter and a method for controlling the same are provided to control PLC devices, which cannot support UPnP, through UPnP. CONSTITUTION: An UPnP PLC adapter(100) consists of a PLC command processing module, a PLC state receiving module, an UPnP discovery server module, an UPnP description server module, an UPnP control server module, and an UPnP event server module. The UPnP PLC adapter(100) makes a virtual PLC route device for PLC devices(500-530) on a PLC network and announces it to the UPnP CPs(Control Points)(200,210) of an UPnP network(300). The PLC command processing module sends a command to a PLC device and receives a response. The PLC state receiving module receives a state change from a PLC device. The UPnP discovery server module receives a search message from an UPnP CP and sends a response message for the virtual PLC route device. The UPnP description server module modifies the description of the virtual PLC route device in case that an additional PLC device is found out or an existing PLC device is removed. The UPnP control server module receives an UPnP control message from an UPnP CP and converts it into a relevant PLC command. The UPnP event server module receives an event registration request message from an UPnP CP and sends an associated response message.
