The present invention relates to an apparatus and a method for providing a virtual API for a web-application mashup service. The apparatus for providing a virtual API includes: a screen data obtaining unit configured to obtain a website screen by accessing a website based on website access information or obtain an application program execution result screen by executing an application program based on application program execution information; and a virtual API processing unit configured to capture an interested area from the website screen related to a virtual API called by a client or from the application program execution result screen and provide the captured predetermined area of interest to the client.

Apparatus and method for providing virtual API for mashup service

In a method for providing content-related information based on a digital watermark and fingerprint, the method includes: receiving a request for content-related information from a client terminal; using a watermark and a fingerprint of content to retrieve the requested content-related information from a database; and transmitting the retrieved content-related information to the client terminal.

System and method for providing content-related information based on digital watermark and fingerprint

Provided is a node control apparatus communicating an external Internet Protocol (IP) network and managing a plurality of mobile nodes included in a local network. The node control apparatus manages information relating to the plurality of mobile nodes, each equipped with one or more wireless interfaces, configures one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes, selects a representative node for each of the groups, and allows the member nodes of each of the groups to communicate with the external IP network via their representative node. Therefore, it is possible to minimize power consumption by selectively using a wireless interface for use in connecting to the representative node of each of the groups.

Energy-saving mobile node control method using wireless multi-interfaces

An apparatus and method for virtualizing multiple terminals are provided. The apparatus includes a terminal virtualizer configured to virtualize a group of a plurality of transmitter terminals of a first user and a group of receiver terminals of a second user through the change of source and destination addresses of a packet that is transmitted between the transmitter terminal group and the receiver terminal group so that the transmitter terminal group and the receiver terminal group may be recognized as if they were single terminals. Accordingly, it is possible to provide seamless IP connectivity regardless of which terminal is currently being used by a user.

Apparatus and method for virtualizing multiple terminals

An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.
