Abstract: An apparatus and method of automatically installing an application in different terminals by storing terminal information of a user and allowing the user to install an application when the user installs an application in at least two terminals, and in which an installation process may be automatically conducted is provided. Information related to an application installed in a first terminal is received from the first terminal; and a second terminal is requested to install another application corresponding to the application, in the second terminal, by using the received information related to the application.

Abstract: A method and an apparatus by which a remote user interface (UI) client device provides a remote UI service, the method comprising receiving an event message, which includes a URL for accessing a first UI resource providing a UI notifying the receipt of a message, from a remote UI server device; obtaining the first UI resource from the remote UI server device by using the URL; receiving external inputs of message control commands via the first UI resource; and transmitting the message control command to the remote UI server device.
