Abstract: A wireless audio output device, a wireless audio output system including the same and a control method thereof are disclosed. When a user approaches the output device, while listening to music on a portable device, the output device automatically connects the wireless audio output system to the portable device, to reproduce the music of the portable device. The control method includes detecting the user, detecting the portable device if the user is sensed, and outputting an audio file being reproduced by the portable device using the wireless audio output system, if the portable device is detected.

Abstract: A method and apparatus to reproduce a media file including reading mapping information from a predetermined position of the media file, searching for a sound field effect file of the media file by referring to the mapping information, and setting an equalizer of the audio data on the basis of the sound field effect file. A user can reproduce a media file by using an optimized equalizer of each media file even though the user himself does not set the equalizer. Also, since an equalizer setting of the reproducing apparatus can be applied to another reproducing apparatus, a user can enjoy listening to a media file in the other reproducing apparatus under the same reproducing conditions as those of the reproducing apparatus.

Abstract: An audio-book playback method includes buffering text data that is to be played back by speech, converting the buffered text data to speech data, performing speech-playback by using the speech data, and buffering next text data for continuous playback. The provided audio-book playback method and an apparatus enable a user to enjoy reading a book while also listening to content of the book being voiced by a multimedia playback device. Moreover, double buffering technology is employed to provide seamless text and speech-playback services.

Abstract: In an electronic device, the physical boundaries of a manipulation unit for inputting a user command defines a contour to which an arrangement of items that are displayed on a display unit conforms. A user's active manipulation of the manipulation unit corresponds to a reaction of a GUI on the display unit. Accordingly, the user can manipulate the electronic device more easily and conveniently.

Abstract: A system providing a remote control device operable both as a cordless telephone and as a computer system having a wireless mouse, with two separate assemblies. The first assembly is a computer system that is connected to a telephone jack. The computer system has a video display unit with a cursor, a modem, and the electronics for a base unit of a cordless telephone built inside the chassis. The second assembly is the remote control unit, and serves both as a handset for a cordless telephone and as a wireless mouse. The handset can place and receive telephone calls by communicating, via electromagnetic radiation to the computer system hooked up to the telephone jack. The handset can also control the position and functions of the cursor on the video display screen when not being used as a telephone. The remote control unit has a mouse button and another cursor control device.

Abstract: A wireless communication system and process for transmission of data communications, may be practiced with a microprocessor, a memory, a controller, a selector and a communication block, and the effect of the wireless communication system for selecting a communication transmission method lies in the fact that a user can select a wireless communication device according to user's needs in a wireless communication device having at least one communication transmission method or a plurality of wireless communication devices having different communication transmission methods, using only one controller.

Abstract: In a mono/stereo input circuit for use in an audio equipment, and more particularly in a circuit for automatically recognizing and receiving mono/stereo audio signals, although a mono connector is inserted into a stereo jack, such an insertion of the mono connector is automatically recognized and then a stereo circuit can operate as a form of a mono circuit. The circuit for automatically recognizing and receiving the mono/stereo audio signals utilizes a fact that one connection terminal of the jack is grounded or not according to a type of the connector such as a mono connector and a stereo connector which is inserted into the jack. Accordingly, a resistor used as a voltage generator generates a generation voltage according to such a connector recognition. Also, using a difference between the generated voltage, the analog switches are turned on or off, to obtain a mono or a stereo audio signal processing circuit according to a type of the inserted connector.
