NCS are the contents such as knowledge, technology, and culture demanded for performing the duties in the industrial field systemized by a nation classified with industrial divisions and levels. It is an ability standardized in the national level necessary for performing duties of industrial field successfully. Now, the society structure, due to abrupt change and development, has to secure core ability demanded to human resources in common, irrespective of kinds and positions, and lays an emphasis on vocational basis ability to softly cope with the accelerating change of labor market. This dissertation, on the basis of NCS-based vocational education curriculum, focuses on information ability, computer use ability(information management ability), one of vocational core competency used for the duties related at the department of video & broadcasting to develop learning module. In addition, this dissertation researches learning results such as satisfaction and accomplishment over learning on the object of the students who took the education.

This paper describes design and fabrication issues of the SiP(System in Package) one-chip for a portable digital broadcasting receiver. It includes RF tuner chip, demodulator chip and passive components for the receiver system. When we apply the SiP one-chip technology to the broadcasting receiver, the system board size can be reduced from $776mm^2$ to $144mm^2$. SiP one-chip has an advantage that the area reduces more 81% than separated chips. Also the sensitivity performance advances -1dBm about 36 channels in the RF weak electric field, the power consumption reduces about 2mW and the C/N keeps on the same level.

This paper presents a scheme that generates a caption file by extracting a Closed Caption stream from DTV signal. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be supported by an enforcing law in all broadcasting services in 2008. In this paper, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file (SAMI and SRT) using the extracted caption data and time information. Experimental results verify the feasibility of a generated caption file using a PC-based media player which is widely used in multimedia service.

The study discussed the link analysis for the Ka band satellite broadcasting service in Korea with respect to the transmission schemes based on the DVB-S2 standard. To analyze the effect of the rain fading to the link budget, we estimated the rain attenuation from the measured rainfall intensity in Korea. We analyzed the link budget for the Ka band transponders of Koreasat-3, and DirecTV BSS-99W, and showed the possible link availability with the DVB-S2 transmission schemes for each transponder. Based on the link analysis of the available satellites with the Ka band transponders, we suggested the required EIRP for the satellite which will be employed for the Ka band satellite broadcasting service in Korea.

We suggest that cultural differences among nations should have a significant impact upon the exports of Korean broadcasting contents due to the fact that production and consumption of the contents are influenced by their own cultural aspects. Based on Hofstede's cultural dimensions frequently cited in the literature, we perform empirical analysis to identify the impact of cultural dimensions upon the export amounts by investigating four-year export data of Korean broadcasting industry. In our research model, Hofstede's cultural dimensions and GDP per capita are independent variables and a genre of broadcasting contents is used as a moderating variable. We find in our analysis that three cultural dimensions such as individualism, uncertainty avoidance, masculinity significantly affect the export amount but do not find the impact of power distance.

It is expected that standardization framework for urban rail transit system will contribute to more convenient and safe traffic service and ensure higher reliability and availability of urban rail transit rolling stock and infrastructure. Since 1995, Korea Railroad Research Institute has been performing the project for standardization and development of urban rail transit technology to improve performance, safety and operational efficiency. Communication system in urban rail transit consists of various subsystems, such as radio communication system, digital transmission system, integrated monitoring system and broadcasting system and its standardization will be implemented based on these subsystem. Broadcasting system is to provide information related to operation and emergency to passengers and operators. In this paper, we suggest standardization scheme for urban rail transit broadcasting system through analysis on present state of the system.

최근 국내 여러 형태의 방송국들이 아날로그 전송에서 디지털 전송 방식으로 점차 변경하고 있다. 이러한 디지털 방송은 다양한 장점을 가지고 있으나, 동시에 고품질 콘텐츠의 불법 복제 및 유통이라는 단점을 안고 있다. 따라서 방송국에선 디지털 방송 콘텐츠에 대한 저작권 보호 기술이 필요하게 되고, 현재 연구되고 있는 여러 가지 저작권 보호 기술 중에서 워터마킹 기술이 공중파 방송 환경에서 가장 적합한 기술로 예상된다. 본 논문에서는 방송 환경하의 저작권 보호를 위한 비디오 워터마킹 기술을 제안하고 제안 기술에 대한 실험 견과를 보인다. 제안하는 워터마킹 기술은 MPEG-2 압축 전 비압축 동영상 신호에 저작권 정보를 삽입하고 전송된 동영상 신호에서 원본 동영상 없이 검출한다. 제안하는 기술은 워터마킹 기술의 3가지 기본 요구 사항인 강인성, 비가시성 및 보안성을 충족하도록 설계하였다

In 21st century, the world media marketing structure began to be re-organized. The development of the digital technology has been realized through new media, add the world markets were merged into one through the opening of markets, which opened the new age of unlimited competition and re-organization of media service providers. The purposes of this thesis are to develop domestic markets by reinforcing the competitiveness of domestic Internet broadcasting (webcasting) under the changes of the world media industry and the expansion of the Internet broadcasting, and to explore strategies to create domestic Internet broadcasting in the rapidly changing world media markets. In this study, the status and problems of Korean Internet broadcasting were analyzed and some strategies for improving current situations were proposed.

This study aims to explore the Internet personal broadcasting quality factors that influence viewer satisfaction and dissatisfaction based on the motivation-hygiene theory. Specifically, the quality factors that affect viewer satisfaction of Internet personal broadcasting are derived from the perspectives of extrinsic (contents usefulness and media usability), intrinsic (emotional/cognitive/behavioral enjoyment and creator characteristics), and social motivation (visibility, subjective norm, image, sociality). The data of 200 respondents was used to analyze the relative impact of satisfaction and dissatisfaction with the Kano model, which assumes that viewer satisfaction at both functional and emotional levels varies over quality attributes. In the empirical analysis, the quality factors were classified into attractive, one-dimensional, must-be, and indifferent quality. In addition, it was found that the customer satisfaction coefficient was high in the order of uniqueness, differentiation, and visibility. On the other hand, as a result of applying the dissatisfaction coefficient, it was identified in the order of donation, content reliability, and creator responsiveness.

It has able to be possible that expression and store visual image from analog to digital without picture quality damaged via improvement of video compression technology. And also, It is possible to broadcasting digital image via transmission of digital image on MPEG-2 standardization. for this reason, the broadcasting business owners have converted broadcasting service from analog to digital. But, local SO(System Operator) has a difficult point which secure HD(High Definition) broadcasting program. In this paper, we designed and implemented Scheduling System for MPEG-2 Digital broadcasting which gather HD broadcasting program from major broadcasting business owners(as like MBC, KBS, SBS, etc) and broadcast them.
