Abstract: The present disclosure includes a diorama space generation and construction module configured to construct an AR map by using a user camera image or image data received through a sensor, a diorama environment tracking and location optimization module configured to load the constructed AR map onto an AR device and track a location of the AR device in a diorama space in real time based on image data received in real time, and a multi-user association and event synchronization module including a user interaction module configured to perform user interaction processing, user event information processing and management, and AR content playback configured to perform interaction synchronization processing, content synchronization processing, and user information synchronization processing.

Abstract: An apparatus and method for representing an editable visual object (EVO) are disclosed. The apparatus for representing an EVO includes a recommendation unit, an editing unit, and a database management unit. The recommendation unit receives the components of a received EVO based on the identification (ID) of the EVO. The editing unit represents the EVO based on the components received from the recommendation unit, and edits the EVO based on information adapted to aid in editing of the EVO. The database management unit performs processing corresponding to a request for the searching of a database when the request is made by the recommendation unit and the editing unit.

Abstract: Disclosed are a sound virtualization method and apparatus. The sound virtualization method includes generating virtual sound devices, generating virtual audio devices on the basis of an audio device, acquiring a mapping relation between sounds created by the virtual sound device and sounds output by the virtual audio device, acquiring the sounds from memories on the basis of the mapping relation, and outputting the sounds through the virtual audio devices according to the mapping relation. Accordingly, it is possible to provide sound to a plurality of users.

Abstract: Disclosed is a system for servicing game streaming, including: a server for servicing streaming game configured to receive game input data and hardware performance information from a user terminal device and service video streaming or merging streaming coupling the video streaming and graphics streaming according to the received performance of the user terminal device; and a database configured to store a background screen and characters for a game streaming service of the server for servicing streaming game.

Abstract: Disclosed herein is an apparatus and method for providing an agent-based game service. The apparatus for providing an agent-based game service includes an input data management unit for collecting pieces of input data from a terminal device of at least one user. A data mining unit analyzes patterns of the pieces of input data and then generates and updates mined data according to the result of the pattern analysis. A game agent processing unit creates, using the mined data, a game agent which will replace the user and play a game instead of the user, and evolves the game agent to correspond to the updated mined data.

Abstract: Disclosed herein are a method of reusing physics simulation results and a game service apparatus using the method. The game service apparatus includes a game service management server, a physics simulation index server, a physics computation cluster, and a rendering server. The game service management server manages physics simulation data corresponding to a game service. The physics simulation index server creates a spatial index structure corresponding to the physics simulation data, and performs spatial indexing for a user area using the spatial index structure. The physics computation cluster performs initial global simulation on the physics simulation data, manages initial global simulation results as reuse data, and performs local simulation on spatial indexing results for the user area. The rendering server merges the reuse data with local simulation results, renders merging results, and provides a game image to a user.

Abstract: Provided are a method and apparatus for determining a block mode using bit-generation probability estimation in motion picture coding. In H.264 video coding for Internet protocol (IP)-television (TV), the method and apparatus first determine whether or not a current block mode is a skip mode or a direct-prediction mode using bit-generation probability estimation, thereby reducing the amount of computation. By minimizing the amount of computation for determining a block mode, it is possible to increase an encoding rate and also minimize deterioration in image quality.
