Lately, airborne digital camera and airborne laser scanner in field of airborne surveying is used to build geography information such as DEM generation and terrain analysis. In this study, 3D position accuracy is compared medium format CCD camera RCD105 with high resolution airborne digital camera DMC. For this, test area was decided for aerial photograph and ground control points was selected in 1/1,000 scale digital map. In Result, Root Mean Square Error(RMSE) was analyzed between RCD105 and DMC after aerial triangulation.

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.

In this age of multimedia, the content of media works as an important factor rather than the format of media. Popular television programs are being supplied cross-border and they go through the process of adaption to the local viewers which is called "formatting". This kind of "formatting" industry had begun in the States, then the Europeans have taken the inactive from 1990s. Since then, it has been settled firmly by the "super-formats". It now has the assumed value of 31 hundred million Euro per year. Especially after 2000s, England has been the center of world broadcasting format industry, and its case has lots of suggestions to Koreans trying to foster the cultural content industry. So this study aims to find the suggestions to Korean content industry by considering the history of broadcast format industry chronically and examining the industrial background of English as a powerful nation of content.

Nowadays the enormous growth of modern information communication technologies and its massive use have influenced information users all over the world. Such a digital environment has drastically changed the information seeking patterns of information users of every community. These also tend law students to use various legal information sources and services in digital environments while seeking information. But there have been few empirical user studies on the aspect of digital information seeking behaviours of law students in either law or library and information science literatures. This paper aims to draw out patterns of information seeking behavior of students of law in digital environments at the University of Dhaka. A stratified random sample survey was conducted for this study. The results show that students prefer the electronic format of information rather than printed format. Major e-resources used by them and the influential factors of use were also identified in this study. This study also identified some crucial problems for seeking information and provides suggestions for the development of electronic legal information systems.

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.

Digital display products are gradually becoming diversified and pursuing high-quality image display. Digital TV supports various video signal formats from conventional SD to digital HD because the format conversion of video image is required. Traditional format conversion of the video image is achieved by a 1-dimensional linear interpolator applying both horizontal and vertical direction. Jagging artifact can be expressed as the linkage of line segments in several directions. In this paper, we present the method that removes jagging artifact effectively using PCA (Principle Component Analysis) and reserve the detail in a given image.

With the National Archives of Korea's establishment of the Selection Criteria for Preservation Format of Digital Records (v1.0) in 2022, criteria have been formed to facilitate the selection of appropriate preservation formats for various types of digital records. With the advancement of technology, diverse electronic file types are produced. However, no specific criteria exist for records other than document types, such as PDF/A-1b. Therefore, the purpose of this paper is to derive intrinsic criteria for selecting preservation formats for audiovisual records, particularly focusing on video-type digital records, to expand the scope of the preservation format selection criteria. Initially, significant properties of video-type digital records were determined, forming the basis for the intrinsic criteria. According to these properties, the video types were categorized into container type and codec type, and three and six evaluation criteria items were derived, respectively. By structuring evaluation criteria for each attribute, this paper proposes intrinsic criteria for selecting preservation formats for video-type electronic records.

As digital images combined with various types of information became popular, the development of transmission format standard for effective application of imageries is demanded. The purpose of the format standard is to provide a universal format that facilitates the exchange of images and related information. In this paper, we found optimal requirements of imagery transmission format standard after reviewing current state of both military and commercial products and studying functions of various types of format standards including NITF (National Imagery Transmission Format). In addition, future research direction of the imagery transmission format standard that complies with current trend of high-resolution and mass storage imagery data is proposed.

LBS(Location Based Service) and GIS (Geographic Information System) are supporting necessary services for system which provides geographic information using location information based on various platforms. However the mobile computing environments such as PDA system have serious limitations in functional viewpoints compare of general computing environments, it has problems for developing GIS system which is providing various information. In this paper, we suggest the reduced methods of digital map and format of web-linked digital mao in order to fit in mobile environment. As a result of map generation, the total capacity of the supported digital map was diminished about $99.34\%$ than the original map.
