Abstract: Disclosed are a multi-screen display system and a method of correcting a time synchronization of image signals respectively played by unit display panels. The multi-screen display system includes a multi-screen display apparatus configured to include a plurality of unit display panels and a timing sensing apparatus configured to sense, outside the multi-screen display apparatus, time synchronization information about the unit image frames respectively played by the unit display panels. The timing sensing apparatus calculates a time synchronization error between the unit image frames respectively played by the unit display panels, based on the time synchronization information, and transmits the time synchronization error to the multi-screen display apparatus.

Abstract: Provided is a data transmitting and receiving method in which a display apparatus connectable to a wireless network transmits and receives data to and from a user terminal by using a pointing apparatus. The data transmitting and receiving method includes (a) acquiring position information of a region, pointed by the pointing apparatus, in the display apparatus and (b) transmitting data, corresponding to an object displayed in the region on a screen of the display apparatus, to the user terminal by using the pointing apparatus.

Abstract: A method of transmitting and receiving digital signage contents, which is capable of easily transmitting and receiving digital signage contents using a smartphone's application, is disclosed. According to an aspect, the method of transmitting and receiving digital signage contents includes: executing an application; transmitting a message for requesting digital signage contents displayed on a digital signage display device to a digital signage manager through the application; receiving the digital signage contents from the digital signage manager; and outputting the received digital signage contents. Accordingly, a user may easily and quickly receive digital signage contents using a smartphone's application, and also, a plurality of users may simultaneously use the same digital signage contents through their terminals. In addition, it is possible to objectively determine the degrees of users' concern and preference about advertisements and digital signage contents.

Abstract: Disclosed herein is a technology for utilizing an indirect experience without copying a real world to a virtual world. An apparatus for providing a visual surrogate for indirect experience according to an embodiment of the present invention includes a synchronization setup unit for setting up synchronization models between a surrogate, a real object and virtual objects corresponding to the surrogate and the real object, wherein the surrogate is a substitute for a remote user and the virtual objects are displayed in a control space. A control space generation unit generates the control space required to input commands for the surrogate and the real object and to output surrounding information sensed by the surrogate. A service provision unit generates an application in which the synchronization models and the control space are packaged.

Abstract: Disclosed is a system and method for generating EJB components by extracting reusable business logic from servlet programs that is one of web program languages used in web-based applications. The system a servlet code analyzer that is a reverse engineering module for analyzing the existing servlet program source, a visualizer for visualizing the analyzed information, a business logic extractor for extracting a reusable business logic, and an EJB component generator for generating the EJB components using the extracted information. The servlet code analyzer considers the flexibility of coding permitted by the servlet program and the use of a multi-language, and the visualizer helps the understanding of the existing legacy program. The business logic extractor extracts the reusable module by extracting the business logic within many user interface related codes, and thus enable the reuse of software. The EJB component generator generates java codes in a jar file that can be deployed.

Abstract: In an apparatus for extracting enterprise beans from a servlet source code, a servlet source code input device receives the servlet source code and a Java class. A Java class extraction device extracts Java classes from the servlet source code. A Java class clustering device groups the Java classes on the basis of interrelated classes. A session bean extraction device and an entity bean extraction device extract a session bean and an entity bean from the clustered classes, respectively. An enterprise bean relationship information extraction device extracts relationship information between enterprise beans from the extracted session bean and entity bean.

Abstract: An inventive apparatus and method are to structurally and movably model frameworks by discriminating classes, control flows and interfaces within the framework, from analysis information generated through a use of a unified modeling language. The inventive method includes a first step of describing, by using the UML, a use case diagram, a flow of events, a sequence diagram and a class diagram; a second step of discriminating frameworks from the use case diagram; a third step of discriminating objects and messages of the sequence diagram and identifying a relation among classes within the class diagram, and thereby structurally modeling the framework; and a fourth step of distinguishing objects, message flows and messages of the sequence diagram, and identifying classes, control flows and interfaces within the framework, and thereby movably modeling the framework. Such embodied framework can be utilized as a substructure in developing software of a computing system.
