Abstract: A display apparatus is provided. The display apparatus according to an embodiment includes a display, and a processor configured to control the display to display a UI screen including a plurality of text objects, control the display to display a text object in a different language from a preset language among the plurality of text objects, along with a preset number, and in response to a recognition result of a voice uttered by a user including the displayed number, perform an operation relating to a text object corresponding to the displayed number.

Abstract: A method is provided for transferring a session between multiple devices by a target device, in which the target device selects a particular session of a source device and sends a request for session transfer for the selected session to a call server, the target device acquires from the call server data that has been transmitted from the remote party's device of the particular session and temporarily stored in the call server after the session transfer request, and the target device sends a message indicating completed acquisition of the temporarily stored data to the call server, and receives the particular session transferred in response thereto.

Abstract: A motion image encoding apparatus for a current image containing an object uses mesh representation for encoding a motion image. The encoding apparatus includes an object extractor for extracting the object contained in the current image from received current image data and outputting object contour data indicating a contour of the extracted object. A predictive encoder performs a predictive encoding operation using the current image data, prestored data of a reference image, and control points of meshes which divide one of the current image and the reference image, and generates motion information relating to the control points, differential data between the current image and the reference image, and predictive image data.
