  • Today, each broadcasting station makes the best use of CG (computer Graphics), which is the latest technology in election broadcasting, and competes to attract the eyes of viewers. This paper investigated the history of CG technology and design transitions in election ballot counting broadcasts from the perspective of CG designers. From the 1980s, when computer-based election ballot counting began, to the full-scale use of virtual studios, the image and technology produced by CG while watching the ballot-counting broadcast video of general elections, presidential elections, and local elections. We analyzed the utilization from various angles. In Korea, we started with the EDDS (Election Data Display System) developed in-house, created a database using a computer, and introduced manual animation CG every day from that time. After that, broadcasting stations focused on diverse and gorgeous CG image competition, and CG images were expanded from 2D to 3D while technology and design developed together. From 1985 to 1992, Korean broadcasting can be seen as a transitional period in which the image changes due to the emphasis on information power while utilizing digital technology.

  • While the management of digital contents is getting more and more important, many researchers have studied about scene change detection algorithms to reduce similar scenes in the video contents and to efficiently summarize video data. The algorithms using histogram and pixel information are found out as being sensitive to light changes and motion. Therefore, visual rhythm gets used in recent work to solve this problem, which shows some characteristics of scenes and requires even less computational power. In this paper, a new scene detection algorithm using visual rhythm by direction is proposed. The proposed algorithm needs less computational power and is able to keep good performance even in the scenes with motion. Experimental results show the performance improvement of about 30% comparing with conventional methods with histogram. They also show that the proposed algorithm is able to keep the same performance even to music video contents with lots of motion.

  • The purpose of this study is to activate the videorecordings in public libraries. The method of activation is to analysis of data which collected through questionnaire from respondent libraries. The results of the study are as follows : 1. The budget of videorecordings is absolutely short. 2 The acquisition policy of videorecordings is not planned because of short budget and little standard selection tool. 3. Most of public libraries wanted to exchange and use of videorecordings through interlibrary loan. 4. The subject of collected videorecordings was almost oriented to the education and motion pictures. 5. Specialized collection policy of public libraries in Pusan is not considered in videorecordings selection. 6. 87 percent of public libraries are not circulate videorecordings to the end-user. 7. Group watching planning of videorecordings in public libraries was done by monthly. 8. 70 percent of public libraries was not perform user reaction survey after watching. 9. 13 percent of public libraries has done the video tape recording of TV programming. 10. Most of public libraries had not a video to introduce themselves and user also had not a plan to create a video. 11. Most of public libraries recognized the copyright law but they wanted to reproduct the videorecordings for user with permission of authors.

  • The purpose of this study is to find trends in new media fashion content by analyzing the fashion content of the official Instagram accounts of domestic fashion magazines that are being transformed by digital media. The framework for these analysis of fashion content type and methods of production is based on one used in an earlier research project. Empirical analysis is conducted on Vogue Korea's official Instagram accounts, using the highest number of major views as the secondary measure of interest. After screening for fashion content in posts on the Vogue Korea account for four months, 291 short video postings were extracted to analyze the number of views the postings received. The results were categorized as 'star', 'show/exhibition', 'product', 'shop', 'fashion film', 'designer', or 'event', included in the data are the number of postings by type and the number of views by post. Based on the characteristics of the creator and the editing, the posts were classified into 'professional production highlight', 'professional production private', 'UCC' or 'GIF' videos, the number of views per post were also collected. The research results show different levels of interest depending on the type of fashion content, and also on the way the videos were produced. The study also investigated how the combination of these two factors affects interest. When producing a new media fashion content, combining a 'star' type post with 'professional production private' video content was most popular. The selection of production method is therefore important even given the same type of content.

  • In this paper, we implemented a terrestrial/cable PSIP converting system, so-called a PSIP converter, which is converting a terrestrial PSIP into a cable PSIP for a data broadcasting service in the interoperable network of terrestrial and cable, and define an interface between the PSIP converter and the OOB SI generator by using PMCP messages compliant to ATSC T3/Sl. The exiting PSIP converter just converts a terrestrial PSIP into a cable PSIP compliant to ATSC and OCAP standard and transmits by a MPEG-2 TS format. That is to say, it is not for the digital data broadcasting but for the digital broadcasting. In addition, the PSIP converter can support various types of PSIP information to the OOB SI generator by using PMCP messages defined by a hierarchical structure as per each channel, audio/video event, data event and so on.

  • Car blackboxes record the information and status of driving. Since blackboxes are commonly used in daily life, the usage of video data recorded from blackboxes is increasing for investigating. Investigators use a own analysis tool suitable for their blackbox provided by the manufacturer in order to check the data. But the tools are not enough to use in the digital forensic analysis because they are dependent on a specific model of blackbox and provides ungeneralized functions. Moreover, if the manufacturer is bankrupt, then their own tools can not be obtained also. Therefore, the way data are stored in the blackboxes which are now in the market are investigated and the features and limitations which have blackbox's own analysis tools are checked. And a comprehensive tool for the analysis of blackboxes is designed and implemented as in this paper.

  • The advent of the 4th Industrial Revolution due to the trigger of digital technologies such as artificial intelligence and big data has caused many changes in society, culture, and industry. However, traditional markets in each region are not responding quickly to new distribution environments and consumer changes. In particular, in the case of traditional markets in Jeju, regional characteristics such as marketing strategies for tourists visiting Jeju have not been utilized. Therefore, this study proposes the establishment of a smart traditional market based on big data and artificial intelligence that utilizes the regional characteristics of Jeju. The research contents include customer profiling through visitor big data analysis, providing tourist movement results through traffic analysis, providing real-time popular product charts, and developing video-based fire and crime prevention functions.
