Streaming server is that an image produced in real time or a file form of image produced ahead consists of SNS service, and the relay module of streaming server includes output management module that set an output channel more than 2 and control transmission of video content. This thesis intends to suggest how to stream through plural output channel that contains output channel of external streaming server using relay module and do streaming provided to terminal receiving image, and streaming server, streaming system for this. Thus, by extending output channel sending out image to output channel of external streaming server, the scale of streaming server is not limited and the process allotting external streaming server into output channel sending the image becomes simple, so management of output channel becomes efficient even when sending several images.

We implement the PBSM (Protocol-Based Security Module) system which guarantees the secure data transmission under web circumstances. There are two modules to implement for the PBSM architecture. One is Web Server Security Module (WSSM) which is working on a web server, the other is the Winsock Client Security Module (WSCSM) which is working on a client. The WSCSM security module decrypts the encrypted HTML document that is received from the security web server The decrypted HTML document is displayed on the screen of a client. The WSSM module contains the encryption part for HTML file and the decryption part for CGI (Common Gateway Interface). We also implement the proposed idea at the web system.

A Remote Monitoring Server(RMS) server which uses Internet and World Wide Web is constructed for SMD in-line system. Hardware base consists of server computer, virtual SMD in-line system and other computers. Software includes assignment of server, RDBMS and various modules in server home page. Web browser provide production quantity, bad PCB quantity, error number and error message in virtual SMD module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module. These functions of the RMS helps a decrease of non-operation time and a service response as fast as possible.

The enterprise find a solution to the problems such as a reduction of manufacturing period, accurate analysis for customer demand, improvement for customer service and rise of manufacture accomplishment. Internet is a good solution to such problems. Internet offers WWW(World Wide Web), remote control, file transfer and e-mail service. Among the services, WWW takes large portion because of convenient GUI, easy information search and unlimited information registration. Remote Monitoring Server(RMS) system that uses network service is constructed for chip mounter. Hardware base consists of RMS, chip mounter and C/S(Customer Service) server. Software includes DBMS and various modules in server home page. This provide product number, bad product number, trouble code, content and countermeasure in real-time information module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module.

The ODBC(Open Database Connectivity) is particularly efficient in the dynamic client/server environment. Besides, the ODBC provides the functions that can handle multimedia data. Due to this feature, we are able to use the DBMS that supports the ODBC as a multimedia server. In this thesis, we describe the development of the ODBC driver for Relational DBMS. The Relational DBMS ODBC Driver consists of the client module and the server module. The client module is called the SRM(Server Request Module) and the server module is CSM(Client Service Module). These two modules are connected through the network module called the NSM(Network Service Module). We have conducted both the functional and the interoperability test of our ODBC Driver It turned out that the ODBC driver operated with these client DBMS tools successfully. In all, due to our development of the Relational DBMS ODBC Driver, DBMS is now capable of processing multimedia data and supporting the client applications including the DBMS tools.

We propose the PBSM(Protocol-Based Security Module) system which guarantees the secure data transmission under web environments. There are two modules in the PBSM architecture. One is Web Server Security Module(WSSM) which is working on a web server, the other is the Winsock Client Security Module(WSCSM) which is working on a client. The WSCSM security module decrypts the encrypted HTML document that is received from the security web server. The decrypted HTML document is displayed on the screen of a client. The WSSM module contains the encryption function for HTML file and the decryption function for CGI(Common Gateway Interface). The formal analysis methodology is imported from format theory for analyzing the data flow of the PBSM system. The formal analysis methodology is based on the order theory.

This paper proposed system for providing the national competency standards learning module, which has changed and updated from time to time. The provisioning server of the proposed system provides learning module, and the management server carry out fault management, billing, request management, statistics and aggregate, etc, and the target server requests the learning module in the provisioning server through the domain. The proposed system determines provide of the learning module by CORS based on filter, which is to determine whether matches or not with domain of the provisioning server and the target server. The proposed system can be patch and maintenance remotely about NCS based learning module to be new update and removed. Also, the proposed system may provide contents in conjunction with existing educational systems, and may be extended in the future to enable the management for domain of the target server.

It is common to use PC or Digital picture frame in stand-alone fashion to view images, movies, or to listen MP3 musics which are considered as multimedia contents, However, such existing methods have weakness for expanding network requirements or augmenting extra data, in such case inevitably requiring external devices. With keeping in mind for such expansion, in this study, we have suggested a new concepts of network module which may utilize an image server for data transmission, in the proposed module, data alarm packet was defined for alerting incoming data from the image server and it became possible to synchronize between the image server and device not only in wired but also in wireless environments through UART. The method consists of a control module for an image server and a synchronization module between the server and the device. We have also tested the feasibility for future commercial usages such as advertisements through performance evaluations.

This paper designs a real-time video playback system using a web camera in the RTSP server. It designs a function to play the video data of the web camera in the client in real time using the web camera in the server and using the RTSP protocol. It consists of a server module function that produces real-time video information using a web camera and a client module function that plays video received from the server in real time. The experiment was conducted by establishing an environment for designing a real-time video playback system using a web camera. As a result of the experiment, it was confirmed that real-time video playback from the server's web camera worked well.

In this paper, we analyzed the signal integrity of a system interconnection module for a proposed high-density server. The proposed server integrates several components into a chassis. Therefore, the proposed server can access multiple computing resources. To support the system interconnection, among the highly integrated computing resources, the interconnection module, which is based on Serial RapidIO, has been newly adopted and supports a bandwidth of 800 Gbps while routing 160 differential signal traces. The module was designed for two different stack-up types on a printed circuit board. Each module was designed into 12- (version 1) and 14-layer (version 2) versions with thicknesses of 1.5T and 1.8T, respectively. Version 1 has a structure with two consecutive high-speed signal-layers in the middle of two power planes, whereas Version 2 has a single high-speed signal placed only in the space between two power planes. To analyze the signal integrity of the module, we probed the S-parameters, eye-diagrams, and crosstalk voltages. The results show that the high-speed signal integrity of Version 2 has a better quality than Version 1, even if the signal trace length is increased.
