Abstract: A method and system wherein a device remotely controls a user interface being executed in a remote device, using a remote user interface. The device discovers a server that supports a remote control interface. The device receives a list of remote devices that the device can control from the server. A selection input is received to select a remote device from the list of remote devices. A device selection request corresponding to the selection input is transmitted to the server. A remote control interface corresponding to the device selection request is received from the server. The selected remote device is controlled via the received remote control interface.

Abstract: In a method of providing/receiving a user interface between a user interface client and a user interface server, when the user interface server encodes information on a plurality of user interface scenes in a multimedia data format and transmits the encoded information to the user interface client. The user interface client receives and reproduces the multimedia data so that a user interface may be displayed to which a variety of effect are applied considering individual characteristics of the user interface client such as performance of the user interface client and user preference.

Abstract: An apparatus and method for controlling a Remote User Interface Server (RUIS) in a Remote User Interface Client (RUIC), wherein the method includes rendering an RUI page for controlling RUISs, receiving an input of a control command for controlling the RUISs from a user through the RUI page, generating a multicast control message for transmitting the input control command in a form of multicast, and transmitting the multicast control message to the RUISs.

Abstract: A service performing method and a service requesting method are provided. The service performing method includes receiving from a second device a message including information representing whether to install a widget for performing a service, and location information of the widget; receiving the widget based on the location information of the widget, and selectively installing the widget based on the information representing whether to install the widget; and performing the service by executing the received widget.

Abstract: A method for receiving additional information from a device in a broadcast communication system is provided. The method includes receiving broadcast information provided from a broadcast service provider over a broadcast channel, extracting application information from the broadcast information, acquiring location information for the additional information associated with a broadcast content from the application information, and transmitting the location information for the additional information to a peer device for displaying the additional information.

Abstract: A method and apparatus for providing a broadcasting service are provided. The method includes receiving, by a first terminal, channel information of a program selected by a user from a second terminal, detecting a frequency of the selected program from a mapping table that maps the channel information to a corresponding frequency, locking a tuner of the first terminal to the detected frequency, and receiving a broadcasting service of the program from a broadcasting network server.

Abstract: Methods, apparatuses, and systems for updating a User Interface (UI) in a Remote UI (RUI) client are described. Upon detecting a change in its capability, the RUI client stores a UI state of a UI page and requests a RUI server to update the UI page according to the changed capability. The RUI client receives a UI page updated according to the changed capability from the RUI server, where the stored UI state is reflected in the updated UI page, and the RUI client renders the UI state-reflected updated UI page.

Abstract: A method for providing a multiplay electronic book content of a client in an electronic book system is provided. The method includes receiving, from an electronic book content server, a multiplay profile and a multiplayable electronic book content which is an electronic book content including multiplay characteristic information, and editing the multiplayable electronic book content so that the content corresponds to a user profile so as to generate a multiplay electronic book content. The multiplay profile includes at least one multiplay parameter which is information regarding the characteristics of relevant electronic book content. The multiplay characteristic information indicates information for tagging which sub-content included in the multiplayable electronic book content corresponds to which multiplay parameter from among said at least one multiplay parameter.

Abstract: A method and apparatus is provided for updating a User Interface (UI) by a Remote UI (RUI) client in an RUI system providing a UI to a user in a remote location.
