This paper proposes an implementation of ODIF(Open Document Interchange Format)decoder and PostScript converter. AS ODIF data stream based on IS 8613 is described according to ASN.1 notation it is necessary to decode ODIF data stream to the proper internal structure to PostScript format as proposed in order to make hard copies in good quality using LBP(Laser Beam Printer). Among several kinds of DA(Document Architecture) and DAP(Document Application Profile). PDA(Processable DA) and Core 26(Level 2 DAP) are selected for our study. An ODIF data stream submitted by ICL is used to show the conformance in the level of data stream.

Today, as era of Internet competition, experimental magazines-created especially for young adult group-are also trying to convert themselves into a internet magazines. This study intends to find out contents format and visual expression that should be considered for on-line conversion of these magazines. The industry's leading experimental magazines, for example, 'ttl', 'Paper', and 'webzine sponge' which co-exist in both printed and web-based format are to be examined by their contents, typography, colors, pictures& illustrations and others. This study intends to exam and suggest possible contents format and visual expression which they ought to evolve with.

The modern digital logic technology does not yet satisfy the speed requirements of real-time DSP circuits due to synchronized operation of multiplication and accumulation. This operation degrades DSP performance. Therefore, the double-base number system (DBNS) has emerged in DSP system as an alternative methodology because of fast multiplication and hardware simplicity. In this paper, authors propose a novel multiplication architecture. One operand is an output of a flash analog-to-digital converter (ADC) in DBNS format, while the other operand is a coefficient in the IEEE standard floating-point number format. The DBNS digital output from ADC is produced through a new double base number encoder (DBNE). The multiplied output is in the format of the IEEE standard floating-point number (FPNS). The proposed circuits process multiplication and conversion together. Compared to a typical multiplier that uses the FPNS, the proposed multiplier also consumes 45% less gates, and 44% faster than the FPNS multiplier on Spartan-3 FPGA board. The design is verified with FIR filter applications.

Life cycle product data is very important yet difficult to handle for manufacturing companies. Shoring and exchanging product data over world-wide-web is a part of key technology to implement PDM or CALS. STEP is widely accepted as a standard to represent the life-cycle product model data. Described in this paper is a web browser plug-in that can graphically display and explore product data represented by STEP over internet. By the use of the plug-in (named "npSTEP"), a product model data stored in STEP format on a web server can be displayed on a commonly used web client (browser), such as Netscape navigator, without any format conversion process. Furthermore one can explore the components or attributes of the product model data in hierarchical manner.

Semantic quirks about the concept of metadata are briefly probed. The reasons behind the conceptual drift are also reviewed. Regarding different formats of metadata, the rationale behind the creation of new formats, their characteristics in relation to MARC format, and problems and methods of conversion or integration of metadata are investigated as background study. RDF (Resource Description Framework) as an integration tool for different metadata standards and Metadata Registry as a candidate for the purpose are studied and the both are compared. It is concluded that two approaches are not mutually exclusive, rather they are complimentary.

This paper proposes the system and method for converting the contents based on DLNA. Digital Media Controller (DMC) compares the media format of content which Digital Media Server (DMS) provides with the media format which Digital Media Renderer (DMR) supports and then, the content is converted dynamically. The interaction between home devices can make a conversion of contents dynamically and it enables people to enjoy the multimedia contents they like to watch whenever/wherever they want.

This study is focused on developing a program which can edit different formats of power system data used by system operators PSS/E program, which has been widely used as a tool for power system analysis. Provides only a limited function of editing PSS/E input data. Considering that more and more power system analysers will be developed and applied for power system planning and operation in the near future, unified handling of multi-types of power system data format, such as conversion of one input data format into another, is indispensible. In this paper, a new power system data editor, functionally augmented from PSS/E editor, is introduced. The new editing program was developed in GUI environment for users to conveniently edit input data for EUROSTAG program without running several editors. Considerable savings in time and manpower are expected.

Led by KIEP, this project to establish an Online Union Catalog System on Northeast Asia is the first such attempt to create a collaboration between social science libraries in Korea. This Online Union Catalog System is seen as a problem solving mechanism, as it helps to maximize efficiency in utilizing labor, finance, and data, by sharing library resources. This study focuses on the process of converting databases in a non-MARC format to a MARC format.

In this paper, we propose a new deinterlacing algorithm based on weighted wide vector correlations. This algorithm is developed mainly for the format conversion problem encountered in current HDTV system, but not limited to. By having wide vector correlations, visually annoying artifacts caused by interlacing, such as a serrate line, line crawling, a line flicker, and a large area flicker, can be remarkably reduced, since the use of wide vector correlation increases the detectability of edges in various orientations.

In the integrated systems, that is integrated digital TV(DTV) internet and home automation, like home server, is needed integration of digital TV video signal and computer graphic signal. The graphic signal is operating at the high speed and has time-divide-stream. So the re-request of data is not easy at the time of error detection. therefore EDAC algorithm is efficient. In this paper, we show a scheme, that is integration of graphic and dtv format signal for DTV monitor display. This paper also presents the efficiency error detection auto correction(EDAC) for conversion of graphics signal to DTV video signal. A presented EDAC algorithms use the modified hamming code for enhancing video quality and reliability. A EDAC algorithm of this paper can detect single error, double error, triple error and more error for preventing from incorrect correction. And it is not necessary an additional memory. In this paper The comparison between digital TV video signal and graphic signal, a EDAC algorithm and a design of conversion graphic signal to DTV signal with EDAC function in DTV system is described.
