Abstract: A method and an apparatus for controlling a virtual screen in a touch screen device are provided. The method includes detecting a touch screen input on a screen view, the screen view displaying a partial area of the virtual screen on a display unit of the electronic device, determining whether the touch screen input is a stylus input or a touch input, the stylus input being executed by a user controlling a stylus and the touch input being executed by the user using a body part of the user, processing the stylus input as a manipulation input corresponding to the virtual screen when the touch screen input is the stylus input, and moving the screen view on the virtual screen in response to a touch movement of the touch input when the touch screen input is the touch input.

Abstract: An apparatus and method are provided for synchronizing a reproduction time of a time-shifted content with a reproduction time of a real-time content. The apparatus includes a tuner/demodulator which tunes broadcasting signals and demodulates the tuned digital broadcasting signals so as to output the broadcasting signals in forms of transport streams, a demultiplexer which demultiplexes the output transport streams so as to divide the transport streams into video data, audio data, and supplementary information and output the video data, audio data, and supplementary information, a data refining unit which removes unnecessary frames from the video data and the audio data, and an HDD which stores the video data and the audio data, from which the unnecessary frames are removed.

Abstract: A remote control device is provided. The device includes an attitude sensing unit that senses the attitude of a device; an axis determining unit that determines one axis in space according to the attitude; a direction input unit that receives a selection command input of one of two directions that are parallel to the axis and are in opposite directions to each other; and a transmission unit that transmits a control signal to move a predetermined graphics object in a direction corresponding to the selection command.

Abstract: A data management apparatus and method. The data management apparatus includes an input unit to receive a request to update information included in a predetermined master BAT (block allocation table) block of a plurality of master BAT blocks; and an update unit to record updated information to the predetermined master BAT block based on the update request.

Abstract: Disclosed herein are an apparatus and method for extracting the aspect ratio of received broadcast content. The apparatus includes an image reception unit, a frequency detection unit, a determination unit, and an output unit. The image reception unit receives a digital image. The frequency detection unit detects the frequency of the predetermined region of the frame of the digital image. The determination unit determines the aspect ratio of the received digital image by comparing the detected frequency with a threshold value. The output unit outputs the aspect ratio of the received digital image based on the result of the determination.

Abstract: An apparatus and a method for controlling key events generated when handling a graphics object are provided. The apparatus includes an event-determining unit that determines a type of an event; an event-managing unit that determines execution of the event depending on the determined type of the event; and a count-checking unit that checks an event count that indicates a number of predetermined event occurrences and a number of times the graphics object has been handled, according to the request of the event-managing unit.

Abstract: An apparatus is provided for displaying all graphic objects after having captured a point in time when an event is transmitted to the last graphic object, when a double buffering method is used, to prevent a transition of a windows system generated by visually observable intervals occurring between events where graphic objects are displayed on a screen by an event handler. Similarly, a method is provided for concurrently displaying graphic objects, the method including checking whether an event to display a graphic object has been generated, storing the graphic object processed according to the event, checking the number of times the event, whose generation has been checked, and the graphic object have been processed, and displaying the stored graphic object as a result of the check.

Abstract: Provided are an information apparatus capable of being controlled using an instant messenger (IM) and its system. In the information apparatus, which is controlled via a predetermined communication network, a driving unit drives the information apparatus. An IM-based interface unit receives a control command for the information apparatus from the communication network, and transfers state data representing the present state of the information apparatus or the function data representing the executable functions of the information apparatus through the communication network. An information apparatus controller receives the control command from the IM-based interface unit, drives the driving unit according to the control command, generates the state data by checking the current state of the driving unit, and transfers the state data to the IM-based interface unit.
