Abstract:
Disclosed is a method for adjusting a ring tone volume in a mobile communication terminal. The method implements a function by which a user can directly adjust the ring tone volume in a mobile communication terminal in consideration of circumstances. To this end, the present invention includes a user interface screen by which a user can adjust the output volume level of the ring tone which rings according to the passage of time. Thus, the present invention provides a user interface screen by which a user can adjust the output volume level of a ring tone which rings according to the passage of time, and enables the user to set the output level of the ring tone and the output time of the ring tone at a corresponding level according to predetermined intervals through the screen.
Abstract:
A composite touch screen panel applied to an electronic device concurrently supports a spatial touch device and a surface touch panel. The panel includes a display module, the surface touch panel, the spatial touch device, and a controller. The display module outputs data. The surface touch panel is disposed on the display module and detects when a touch on a surface of the touch screen panel. The spatial touch device is interposed in constituent elements of the surface touch panel. And a controller senses a touch position detected in the spatial touch device and the surface touch panel, and performs a corresponding function of the electronic device.
Abstract:
Disclosed is an audio/video data synchronization apparatus for directly transmitting decoded audio/video data to an external device, without compressing the data, using UWB communication. The apparatus synchronizes video and audio data stored in a terminal without compressing the data and simultaneously transmits the data to an external device using UWB communication, so that users can enjoy high-quality images and sounds. In addition, the receiving end does not necessarily incorporate a separate function for decoding moving images, because it receives uncompressed video/audio data. This makes the apparatus simple and convenient.
