Abstract: An apparatus and method for controlling volume in a terminal adjust the volume of applications in the terminal without adjusting a main volume of the terminal. The apparatus and method display the relative volume of applications and allow a user to adjust each application's volume. If a user adjusts the volume of an application to be greater than a main volume of the terminal, the application's volume may be set to the main volume of the terminal.

Abstract: A method for controlling an image may include activating a selected area of the image based on a touch point, setting the selected area according to a maintained touch input or according to a second input, increasing a zoom of the image, and outputting the zoomed selected area if a touch release is sensed. An apparatus to control an image displayed on a screen may include a touch sensing unit, a display unit, and a screen processing unit of which the screen processing unit activates a selected area and zooms the selected area based on a touch.

Abstract: Provided is an apparatus and method for transmitting a signal based on interleaving delay diversity. The transmitting apparatus includes: a converting unit for converting an input data into a plurality of low data rate bit streams; a modulation unit for modulating the plurality of the low data rate bit streams by using Walsh codes, to thereby generate modulated signals; an adder for adding the modulated signals to generate a summation signal; a dividing unit for dividing the summation signal into at least two branch signals; a signal processing unit for generating a first output signal by interleaving one branch signal to generate an interleaved signal and multiplying the interleaved signal with a first code, and generating a second output signal by multiplying another branch by a second code; and a transmission unit for transmitting the first output signal and the second output signal, wherein the first code and the second code are orthogonal to the Walsh codes.
