Chatting room has become widely using technology and it is vulnerable to the internet attackers. We proposed a chatting system using a Purebasic programming language to communicate across networks system. Chatting room text is a form of instant messaging between two or group of people. A Communication experiment was designed and implemented to confirm the validity of the developed chatting system on a trusted platform.

Although digitalization of broadcast waves is extending the multichannel programming capabilities of broadcasting, it does not fully exploit the potentiality of the digital evolution in broadcasting. ISDB has been put forth as second-generation digital broadcasting which offers a basis for a universal service in the future multimedia environment, and opens many new possibilities for services and their use. The paper is divided into three parts: A vision of the future of broadcasting, Evolution towards ISDB - integrated Services Television, and Technology development.

In this paper, we present an automatic C source code generation system for DirectShow based multimedia application programming. In this system, C source code is automatically synthesized from the filter connection graph edited with GraphEdit, a utility tool provided with DirectShow SDK package from Microsoft. In traditional DirectShow programming environments, program design and brief testing steps are usually done with GraphEdit tool just by inserting filters and connecting them properly, while actual implementation of the program should be done separately. The filter connection graph information from GraphEdit is used just as a reference in such the implementation step. Therefore, our system which automatically generates C source code directly from the filter connection graph of GraphEdit seems very useful and many programmers can develop DirectShow based multimedia application programs more effectively and quickly using our system. In addition, our system supports more various media stream control functions for the generated application programs than the existing system such as Wizard which supports limited and fixed number of media control functions only. This feature allows more flexibility in the user interface of the generated source program and makes our system more practical for DirectShow based programming.

2007 revised curriculum in primary schools by the educational programming should be carried out due to a number of practical constraints have been performed well. Elementary education program conducted by the EPL and Scratch Programming for haneunge was not long after the development of intuitive interface and blocks created using the syntax, contains multimedia elements, such as the benefits that can create artifacts due to the elementary education program is appropriate for. The researcher targeted the school for a semester, 4th year 12 weeks based on the results of scratch programming, programming by way of the Plan and the training and the results were analyzed. Scratch programming to increase student interest and enhance creativity and Formal help cultivate the scientific attitude can give you results. Scratch Programming for Elementary EPL Education is an effective lead of the students' prior knowledge or interest in sex by level of achievement because of the variation to allow individual learning needs to organize a program of study. And results in the production of sufficient thinking ahead and given time to discuss the purpose of education and programming will need to be alive.

A new methodology of multimedia data composition generated SRT(Synchronization Relation Tree) dynamically after user composing multimedia date by using high level user interface, and processes message passing protocols to adjust multimedia data temporal composition. In this paperl we propose SRT generating algorithm which transfer user defined timeline diagram to SRT dynamically. SRT generating algorithm is to use divide and conquer methodology and recurvise programming. And prove that it generates and type of multimedia date compositon to SRT.

In this monograph, we developed a Remote Courseware Management System so we can more easily cultivate a courseware with various multimedia applications through an easy interface with the internt. In the view of Developer of view, we could develop RCMS rapidly using the application of ASP.NET and have tried to adapt ourself to the future environment using it. ASP.NET provides much richer event programming model than ASP and event processor which are executed on Server. In the view of User, they can used the Internet service with equipment that they want at any place and any time. To control any kinds of courseware for Administrator and Users, we offered a variety of Multimedia applications and an easy interface and built a new style of web courseware.
