Abstract: The present invention relates to an apparatus and method for processing a stage performance using digital characters. According to one embodiment of the present invention, an apparatus for processing a virtual video performance using a performance of an actor includes a motion input unit for receiving an input motion from the actor through a sensor attached to the body of the actor, a performance processor for creating a virtual space and reproducing a performance in real time according to a pre-stored scenario, a playable character (PC) played by the actor and acting based on the input motion, a non-playable character (NPC) acting independently without being controlled by the actor, an object, and a background being arranged and interacting with one another in the virtual space, and an output unit for generating a performance image from the performance reproduced by the performance processor and outputting the performance image to a display device.

Abstract: An apparatus and a method for providing a multimedia service which can automatically recognize various media corresponding to communication contents and provide information regarding to the media in bi-directional or multipoint communication. The method includes the steps of classifying a type of input multimedia data, detecting context of the multimedia data through a search scheme corresponding to the classified multimedia data, determining a search request condition of related/accessory information corresponding to the detected context, receiving the related/accessory information about the context by searching the related/accessory information corresponding to the context if a related/accessory search condition is satisfied as a determination result of a search condition, and providing the multimedia data and the related/accessory information about the context of the multimedia data to a user.

Abstract: A method for managing user schedules, which includes inputting data; determining if the input data corresponds to schedule data or request data; extracting a function necessary for executing an action which a user must perform at a specific time for the schedule data or the request data; determining a main element type according to the extracted function; and storing the input data when the input data correspond to the schedule data according to the main element type, and executing the extracted function and outputting results obtained by executing the extracted function when the input data correspond to the request data.
