As the subscribers of the digital cable and IPTV broadcasting are increasing, the VOD service has established a solid foothold as a profit model of the broadcasting industries. And what's more, the VOD service is emerging as a key application of the N-screen technologies. In the circumstance, broadcasting companies are trying to provide mobile services to improve the satisfaction of their VOD services usage. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs printed on a VOD guide book, directly transmitting the information (e.g., book-marking, remote-control signals) generated by the VOD mobile app to a set-top box, and watching the video contents stored in the mobile device on TV.

The existing wireless village broadcasting systems use the method to connect to village broadcasting system using wire/wireless telephone to announce the important notices, public relations, and disater status. This type of systems have the problems that if broadcaster is facing rough going or forget the announcement time, it is impossible to inform village people important contents, urgent disaster status, evacuation method. This paper describes internet based village broadcasting system using mobile App to solve these problems. Broadcaster can save the voice and send the voice to App server using the mobile App to activate that voice specific day and time. This mobile App system can improve the efficiency and customer satisfaction of village broadcasting system.

The purpose of this study is to provide an effective program contents of information supplied by broadcasting media with the aim of developing health program models. Health programs which have been aired and are being aired on KBS I radio, KBS, EBS, Cable TV and SBS radio were analyzed in order to understand the issues of current health programs and to design a plan for improvement. In order to address current issues of health programs, the range of health information should be extended to meet various expectations from the public audience, in addition to dealing with diagnosis and treatment of illnesses. Programs should be capable of encompassing various issues such as health practice, prevention, information on medical facilities, public health policies, daily health information, and the role of patients. As health programs function as major information sources for health services, it is necessary to raise the quality and credibility of broadcasting. Broadcasting agencies has a responsible role for public health promotion through health programs. In order to make it possible for broadcasting to fulfill its social responsibility, it is advisable to develop programs that have a clear understanding of what is the cognition of the public and the level of demand in regard to health programs.

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.

현재를 '빅데이터' 시대라 부른다. '빅데이터', 그 용어가 주는 의미대로 우리가 처리해야 할 데이터가 매우 많다는 것을 의미 하며, 과거의 데이터 정제 기술로 유의미한 정보로 가공하려면 상당한 자원이 필요하다. 현재, 장비의 고성능화 등으로 가능성이 검증되고 있고, 일부 비즈니스에 활용되는 단계이나 여전히 혼돈의 문제가 존재하며, 이러한 문제의 해결책으로 제시되는 것 중의 하나가 바로 '소셜 큐레이션'이라 할 수 있다. 본 개발 서비스1)는 시청자들이 방송 콘텐츠를 소유하고 공유하고자 하는 욕구를 반영하여, 실시간으로 TV를 보면서 방송 프로그램을 캡처하고 공유할 수 있게 한다. 방송콘텐츠에 관한 '소셜 큐레이션' 서비스이며, 이는 각 사용자들이 캡처하여 생성한 수많은 콘텐츠 중에서 사용자들이 원하는 콘텐츠를 사용자들의 사회적인 관계를 이용하여 선별적으로 제공할 수 있도록 구성한 것이다. 본 논문에서는 서비스의 개발 방향과 시스템 구성 등을 설명한다.

Unified speech and audio coding (USAC) is one of the latest coding technologies. It is based on a switchable coding structure, and has demonstrated the highest levels of performance for both speech and music contents. In this paper, we propose an extended version of USAC with a single-mode of operation-which does not require a switching system-by extending the linear prediction-coding mode. The main concept of this extension is the adoption of the advantages of frequency-domain coding schemes, such as windowing and transition control. Subjective test results indicate that the proposed scheme covers speech, music, and mixed streams with adequate levels of performance. The obtained quality levels are comparable with those of USAC.

'빅데이터', 그 용어가 주는 의미대로 우리가 처리해야 할 데이터가 많다는 것을 의미하며, 과거의 데이터 정제 기술로는 유의미한 정보로 가공하기에는 상당한 노력이 필요하다는 것을 암시하고 있다. 현재 장비의 고성능화 등으로 가능성이 검증되고 있고 일부 비즈니스에 활용되는 단계이나, 여전히 혼돈의 문제가 존재하며, 이러한 문제의 해결책으로 제시되는 것 중의 하나가 바로 '소셜 큐레이션'이라 할 수 있다. 본 'TVzzik' 서비스는 시청자들이 방송 콘텐츠를 소유하고 공유하고자 하는 욕구를 반영하여, 실시간으로 TV를 보면서 방송 프로그램을 캡처하고 공유할 수 있게 한다. 방송콘텐츠에 관한 '소셜 큐레이션' 서비스이며, 이는 각 사용자들이 캡처하여 생성한 수많은 콘텐츠 중에서 사용자들이 원하는 콘텐츠를 사용자들의 사회적인 관계를 이용하여 선별적으로 제공할 수 있도록 구성한 것이다. 본 논문에서는 'TVzzik' 서비스의 개발 방향과 시스템 구성 등을 설명한다.

Traditionally R&D evaluation has been performed by experts who can understand the contents of the study area very well. Recently extensive application of quantitative evaluation methods have been attempted for introducing the administrative management system that poses greater importance on records and results. More objective reviews on the R&D outcomes are called for gaining public supports. In this paper a bibliometrical analysis is to be performed to evaluate satellite communication and broadcasting public R&D outcomes for last 7 years. Data envelopment analysis method is selected for evaluating the efficiencies of multiple outputs (papers, patents, royalties, technology transfers) where multiple inputs (number of researchers and R&D expenses) are given. R&D outcomes from 22 research institutes are being compared and satellite communication and broadcasting R&D efforts turn out to be highly efficient.

High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.
