  • In this paper, typical types of digital format were defined and digital format selection guidelines of US's NISO(National Information Standards Organization) and LC(Library of Congress) and Denmark's The State and University Library and the Royal Library were introduced. Five sustainability factors and quality and functionality factors were raised through analysing the three sample guidelines. The sustainability factors include descriptive, independency, consistency, widely adopted, and quality. Thus, digital format selection strategies for a library were developed.

  • GIS (Geographic Information Systems) technology is a necessary function to support location based on service by using GPS in the mobile environment. These mobile systems have basic functional limitations such as a low rate of processing, limited memory capacity, and small screen size. Because of these limitations, most of the mobile systems require development of a reduced digital map to overcome problems with large-volume spatial data. In this paper, we suggest using the reduced digital map format in order to use location based on service in a PDA environment. The processing of the proposed data format consists of map generation, redefinition of layers, creating polygons, and format conversion. The proposed data format reduces the data size by about 98% comparing with DXF format based on the digital map of Busan.

  • This paper propose the "Digital Format Registry(DFR)" to solve the problem related digital objects preservation system in the Korean Industry. Digital format registry is a kind of database that saves syntax and meaning informations of a digital file format and for giving help to make preserve in long-term even technical environment of a specific application has been changing. The role of the Technical Information Registry has been developed in this research and development is maintaining a technical information that is the foundation to maintain the long-term preservation and access to a digital objects. The function that can extract text information from a digital document object is implemented in DFR as a basic function at the first time in the world. This function make information consumers search a information that is needed easily and conveniently and can be used for development more effective records management system with retrieving the Key(index).

  • In this paper, we proposed the vehicle data format of digital tachograph to improve the vehicle data format of the MOLIT(Ministry of Land, Infrastructure and Transport). The vehicle data collection and analysis is currently available through digital tachograph mandatory installation for commercial vehicles. And public agency is used the vehicle data format as a transmission format defined by MOLIT's guideline for their vehicle data processing. However, Vehicle data format is different for each manufacturer and MOLIT's vehicle data format is also need to advance. We confirmed the proposed the vehicle data format improved based on the vehicle data format of MOLIT through the system implementation and experiment in this paper.

  • DVR(Digital Video Recorder) system stores video inputs in compressed digital formats and retrieve them. DVR system has several advantages over traditional analog tape recorder system which are (1) improved real-time monitoring, recording and searching capability, and (2) other capabilities such as watermarking and remote monitoring through network. AVI format is the most popular format used for DVR systems. However, AVI format has drawbacks in recording and searching due to structural problem. Some vendors develop and use their own format, do not open the format to the public. In this paper, ESP format is proposed. ESP format solves the drawbacks of AVI format, and the advantages of AVI format apply to ESP format. Moreover, ESP format provides multistream recording/replay and event-recording. In result, ESP format enchances functionality of recording and searching in DVR system.

  • Electronic records are merely series of bits without understanding the formats of content files. There are numerous types of formats and also possibilities of extinction. For long term preservation, it is essential to understand and manage formats. In addition to managing format itself, accurate information on the format needs to be stored for electronic records. In this study, various types of electronic files, without checking with the naked eye, has developed a tool to extract the header information in the format of electronic files with the file extension validation tool to compare format and validate digital component.

  • CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.

  • The study aims to analyze the characteristics and problems of raw image file formats, evaluate its suitability for the management of digital photographic records, and suggest the introduction method to utilize such format in public institutions. Raw image file formats feature reversibility and flexibility. However, most of them are proprietary file formats that depend on the digital camera manufacturer. The DNG format, which was developed to standardize raw image file formats, has received positive reviews from overseas public agencies. However, the DNG format is not fully recognized as a standard; hence, it is appropriate to use it tentatively until the standard raw format appears. On the other hand, the converted digital photo file format is not recognized as an original with legal authenticity. Therefore, in the short term, DNG files created by format conversion and original raw files should be encapsulated and preserved. Furthermore, it is necessary to redefine the baseline of the hash value and file size to recognize the legal authenticity only with DNG files in the long term.

  • GIS systems have gradually been utilized in life information as well as special businesses such as traffic, sight-seeing, tracking, and disaster services. Most GIS services focus on showing stored information on maps, not providing a service to register and modify their preferred information. In this paper, we present a new method which reduces DXF map data into Simple Geographic Information File format using format conversion algorithms. We also present the prototype implementation of a GIS search system based on ontologies to support associated information. Our contribution is to propose a new digital map format to provide a fast map loading service and individual customized information on the map service.

  • Since the first HDV(High Definition Video) camcoder, HDR-FX1 with 1080i resolution, had been launched at 2004, the image capture and record with HD resolution have been possible by the various types of camcoder and recorder which can support the HDV format. At a present day, a non-linear editing system, which is composed of only one computer, can capture, edit and export the image with HDV format. The HDV format has the same class of resolution with HD and the same data transfer bit rate of DV(Digital Video). Additionally, the image with HDV format can be recorded in 6mm DV cassette tape. It is possible because the HDV format uses the concept of Long GOP(Gorup of pictures) method for its compression. In this paper, the characteristic feature of HDV format, the essential factors in editing with HDV format and the concept of Long GOP method for its compression have been studied for the way of effective HDV editing.
