Provided are a method and apparatus for rapidly recovering a network connection interrupted by a change in an Internet Protocol (IP) address of a Universal Plug and Play (UPnP) device. In the method, a second address of a device is obtained using a message signaling an end of a network connection based on a first address of the device, and a second address-based network connection is set using the obtained second address.

Method and apparatus for recovering interruption of network connection caused by IP address change of universal plug and play (UPnP) device

An apparatus and method for processing data stream are provided. A query execution plan for processing data stream is shared between the server and the terminal. The server builds a query execution plan and determines a part of the built query execution plan to be executed in the terminal. The terminal executes the part of the built query execution plan and transfers a result of the execution. The server executes the remaining part of the built query execution plan based on the execution result transferred by the terminal. The part of the query execution plan to be executed in the terminal is determined depending on the performance of the terminal.

Apparatus and method for processing a data stream

An apparatus and method for processing a data stream using a cluster query, are provided. Collected queries are clustered into a predetermined vector space based on a feature vector of the collected queries. In response to a query received from a user, the received query is classified to a cluster and may be replaced with a centroid query of the cluster to which the received query belongs. The data stream processing apparatus processes the centroid query and provides an approximate result to the user.

A method and apparatus for processing moving image ancillary information, based on a script, is provided. The method includes receiving a user command for inputting ancillary information, where the ancillary information includes a script for a moving image being played. The method further includes storing the ancillary information input by a user, searching for and extracting the stored ancillary information during playback of the moving image, and outputting the extracted ancillary information to an image display screen using the script.

Apparatus for processing moving image ancillary information based on a script and method thereof

A mobile device and an apparatus and method for the mobile device, in which intercept information about contents intercepted by a user is stored in the mobile device and is transmitted together with a request for contents from the user, so that the user can use only the selected contents. The mobile device includes a content analysis unit analyzing predetermined contents and extracting selection information by which a user can determine whether to intercept the predetermined contents; an intercept information storage unit storing intercept information about intercepted contents intercepted by the user based on the extracted selection information; and a control unit transmitting the stored intercept information to a content-providing device.

Mobile device, and apparatus and method for transmitting content for the mobile device

A method and apparatus for utilizing DVD content through a home network are provided. The method includes transmitting item information indicating DVD content in response to a request for a content list, and receiving a request for the DVD content in units of a sector from a client having acquired the item information, and extracting and transmitting data of the requested sector to the client. Various functions provided by the DVD video can be utilized similar to reproducing DVD content through a local DVD player while reproducing DVD content stored in a remote server through devices of a home network. Therefore, it is possible to reduce concerns of the DVD copyrighter about illegal copying of the content since encoded data is transmitted as it is, without being decoded.

Method and apparatus for utilizing DVD content through home network

An apparatus and method capable of purchasing external charged content in a UPnP network are provided. A media server (MS) provides a media renderer (MR) with a URL that executes a CGI that that performs purchasing of a charged content included in an external server, and, if the MR requests the reproduction of content corresponding to the URL, the MS executes a CGI of the URL, purchases charged content corresponding to the URL, and downloads the charged content, thereby browsing a list of contents provided by an external contents purchase site through a consumer electronic device such as a digital television, in which a UPnP audio/visual control point is mounted without a separate interface, purchasing desired content, and reproducing the purchased content.

Method and apparatus for obtaining external charged content in UPnP network

A method and system are provided for allocating a dynamic advertisement according to audience ratings. The method includes selecting an advertisement broadcast to be transmitted based on broadcast viewing information of users and a transmission condition, and providing the selected advertisement broadcast.

System and method of dynamically allocating advertisement according to audience rating

Disclosed are a method and apparatus for outputting a user interface (UI) event of a 3rd party device in a home network having a server, a client and a control point, the server and the client joining a UI session by using a remote protocol, the control point controlling the server and the client. The method includes (a) receiving by the control point a UI event message from the 3rd party device not joined in the UI session, the UI event message representing change in a state of the 3rd party device, (b) selecting by the control point a target client for processing a UI event, (c) transmitting by the control point an Out-of-session connect action message (OOSConnect Action) requesting connection setup with the 3rd party device to the selected target client, and (d) transmitting by the target client a permission message for the OOSConnect Action to the control point, thereby setting an Out-of-session connection OOSConnect with the 3rd party device and processing the UI event.

Method and apparatus for outputting a user interface (UI) event of 3rd party device in home network

Provided are an apparatus, system and method for providing an Internet print service in a home network, more particularly, an apparatus, system and method for more conveniently providing an Internet print service via a UPnP printer in a home network. The apparatus includes a UPnP printer managing unit supplying an interface to provide an Internet print service and receiving a print job request from a UPnP printer control point; a job-processing unit making a request for a print service to an external Internet print site in response to the print job request; and a user-information-managing unit managing information necessary when the Internet print service is used.

Apparatus, system and method of providing internet print service via home network

A method and apparatus for managing information regarding a Universal Plug and Play (UPnP) device when an Internet Protocol (IP) address of the UPnP device is changed are provided. In the method, a second address of the UPnP device is obtained from a message indicating the end of a first address-based network connection based on a first address of the device, and information regarding the UPnP device is updated by using the second address.
