When the screen touch is the spiral touch, the screen is magnified or reduced.

Abstract: An apparatus and method for multimedia file streaming are provided. In a method for multimedia file streaming in a receiving portable terminal, the method includes determining meta data included in a received packet, generating new meta data having a circular-type media data offset on the basis of the meta data, storing media data included in the packet received in a circular manner according to the media data offset included in the new meta data, and loading the media data stored according to the media data offset included in the new meta data.

Abstract: A terminal and method for providing user interfaces linked to postures of a terminal, whereby a key input signal is received from any one of function keys located at both sides of the terminal, a posture of the terminal is determined in response to the received key input signal, a user interface screen corresponding to the determined posture of the terminal is provided, and settings of the terminal are changed according to the determined posture of the terminal, thereby increasing convenience of a user interface without use of a complicated sensor system.

Abstract: An apparatus and a method transact digital contents. More particularly, an apparatus and a method for inserting a purchaser's signature into digital contents and providing the same in a digital contents management system are provided. The apparatus includes a purchaser terminal, a contents server, and a receiver terminal. The purchaser terminal detects a user's input, writes a signature to be inserted into contents, and transmits the written signature to a contents server when purchasing contents. The contents server inserts the signature received from the purchaser terminal into original digital contents. The receiver terminal receives and reproduces the original digital contents to which the signature has been added.

Abstract: An apparatus and a method for making three-dimensional (3D) contents production possible in a mobile terminal are provided. More particularly, an apparatus and a method for allowing a general user to easily produce 3D contents by providing an edit tool for producing 3D contents in a mobile terminal are provided. The apparatus includes an object generator. When detecting an input for transforming the 3D object, the object generator determines a 3D object transform value depending on an input strength, and applies the transform value to the 3D object.

Abstract: An apparatus and method for providing a coupon service in a mobile communication system are provided. A method of operating a user terminal for providing a coupon service in a mobile communication system includes receiving coupon information of one or more shops that exist within a specified range around the user terminal from a Social Network Service (SNS) server, displaying the received coupon information, and generating a coupon by using the coupon information of the shop at the request of the coupon information, wherein the SNS server receives coupon information uploaded from a vendor terminal and Global Positioning System (GPS) information of a shop capable of using the coupon service.

Abstract: A method and an apparatus produce and reproduce Augmented Reality (AR) contents in a mobile terminal. In the method, contents are produced. An image including an object corresponding to the contents is recognized. Recognition information for the object corresponding to the contents is obtained based on a recognition result. AR contents including the contents and the recognition information are generated. Therefore, AR contents for an input image may be easily produced and reproduced, and the AR contents may be used as independent multimedia contents, not an auxiliary means of other contents.

Abstract: An apparatus and method display a world clock on the basis of an Augmented Reality (AR) scheme in a portable terminal. The method for displaying information in the portable terminal includes obtaining camera image data from a camera. The method also include searching for a city corresponding to a camera location and a camera viewpoint direction on the basis of a memory. The method further includes obtaining information on the found city and displaying the obtained information on the found city by compositing the information into the obtained camera image data.
