Abstract: The present invention provides a user terminal and a control method of the same, in which a first object is easily changed into a second object by moving to an edge region on a screen. The user terminal includes: an image processor configured to process an image; a display configured to display the processed image; and a controller configured to control the image processor so that a first object included in the image can be moved to an edge region on a screen of the display in response to a user's input for moving the first object to the edge region on the screen of the display, and the first object can be changed into a second object smaller than the first object and displayed on the display.

Abstract: An image sensor includes a plurality of pixels disposed in an array, each pixel comprising a first region and a second region, the first region and the second region separated from each other in a semiconductor layer, and doped with impurities having different conductivities from each other, a photoelectric conversion region formed between the first and second regions, and at least one metal nanodot that focuses an incident light onto the photoelectric conversion region.

Abstract: A system and method for presence subscription delegation in a multi-domain environment in an SIP-based presence system are provided, in which a watcher transmits a presence subscription delegation request to a presence subscription delegation handler of a delegating user, the presence subscription delegation handler performs delegation authorization for the received presence subscription delegation request according to a presence delegation authorization rule of the delegating user being authorization information about presence subscription delegation, and a presence server of a presentity receives the presence subscription delegation request from the presence subscription delegation handler, performs presence authorization according to a presence authorization rule of the presentity, and transmits presence information about the presentity to the watcher via the presence subscription delegation handler.

Abstract: A method and an apparatus for editing Digital Rights Management (DRM) content in a portable terminal are provided. The method includes if an event for editing a DRM file occurs, allowing a user to set use purposes of the DRM content of the DRM file; and specifying the use purposes of the DRM content in an editable box of the DRM file. Thus, use purposes of DRM content of a multi-DRM file can be specified using an editable box of the multi-DRM file.

Abstract: A method for selecting an audio language of a digital broadcasting receiver, including determining whether an audio language selection has been made, increasing an audio language on-screen display order number by one, setting a previous audio language on-screen display order number to equal the value of the increased audio language on-screen display order number, displaying a current audio language index, fetching a new current audio language index and setting the current audio language on-screen display order number to correspond to the new current audio language index, comparing the previous audio language on-screen display order number with the current audio language on-screen display order number, and displaying the new current audio language index when the previous audio language on-screen display order number and current audio language on-screen display order number are different.

Abstract: Radio-frequency (RF) power control circuit that facilitates establishment of RF power levels of the mobile radiophone, is disclosed. The circuit maintains constant RF power levels even if the variable resistor is displaced by vibrations and impacts caused by moving of the mobile radiophone.
