Abstract: A coil component is provided. The coil component includes a body having fifth and sixth surfaces opposing each other, first and second surfaces respectively connecting the fifth and sixth surfaces of the body and opposing each other, and third and fourth surfaces respectively connecting the first and second surfaces of the body and opposing each other in one direction, a recess disposed in an edge between one of the first and second surfaces of the body and the sixth surface of the body, a coil portion disposed inside the body and exposed through the recess, and an external electrode including a connection portion disposed in the recess and connected to the coil portion, and a pad portion disposed on one surface of the body. A length of the pad portion in the one direction is greater than a length of the connection portion in the one direction.

Abstract: A method for an information push service at a mobile station based on a wireless local area network (LAN) access point (AP). The method includes receiving a beacon message including a shortened Uniform Resource Locator (URL) from at least one AP, acquiring information based on the shortened URL included in the beacon message, and displaying the acquired information together with information included in the beacon message. The method allows a user to simply, conveniently, and easily acquire and make use of peripheral information of an area in which the user is located. The method also provides a service dependent on information on a position of contents, thereby being capable of allowing the user to easily access the contents.

Abstract: An electronic apparatus is capable of transferring contents on a cloud system to a device connected to a DLNA. In a method for operating a client on the cloud service system, a stream meta data table including information of one or more contents is received from a server. Meta data of contents selected from the contents are converted such that the meta data coincide with a format used by a device selected from one or more devices connected to a network. The selected contents are streamed from the server and transferred to the selected device.

Abstract: An image management method and system are disclosed which can increase user convenience by reducing a display time of thumbnails in a DLNA system. The DLNA system includes a digital media server for generating a thumbnail group image using thumbnails corresponding to at least one original image file and transmitting the thumbnail group image, and a digital media player for receiving the thumbnail group image from the digital media server and requesting the digital media server to transmit an original image file corresponding to a selected thumbnail among thumbnails included the thumbnail group image.

Abstract: A method and apparatus for establishing communication between a first device and a second device. In the method, the second device recognizes a mark representing the first device to establish communication with the first device, and establishes communication with the first device, based on information included in the mark.

Abstract: A Digital Living Network Alliance (DLNA) system and method of providing content therein are provided. A legacy media player displays a content list for content stored in the legacy media player or in an add-in server, and when a content item is selected from the list, the legacy media player determines whether the content item is reproducible by a registered digital media renderer. If the selected content item is reproducible by the registered digital media renderer, the legacy media player transmits a reproducing request for the selected content item, and the corresponding digital media renderer receives and reproduces the selected content.

Abstract: A method and apparatus for determining an object update in a home network. In a method for determining an object change in a home network, a media controller receives an object update identifier (objectUpdateID) and an initial update identifier (initUpdateID) for an object from an accessed media server, compares the objectUpdateID and the initUpdateID with a system update identifier (systemUpdateID) that was previously stored in the media controller, when the media controller previously accessed the media server, and determines whether the object is updated according to the comparison result.

Abstract: Provided is a method for storing a content flip list of a digital media server using user input feedback. The method includes receiving a content request message from a user and transmitting the received request message to a media server, converting information received as a response to the request message into a page format, defining the converted information as a current page, and receiving and storing previous and next pages of the current page, and outputting the received current page through an output part.
