From the perspectives of regulation and convergence, several debates on the industrial definition of smart TV service in the Korean broadcasting and communications market are currently in progress. The most heated controversy mainly depends on whether smart TV is controlled under broadcasting regulations or under communications regulations. This Korean- specific problem is summarized in regulation fairness or asymmetric regulations between smart TV and IPTV operators. Although both operators utilize very similar technology and share the same business model, the regulations for only smart TV operators are unfettered. This would be an intrinsic cause that prohibits fair competition in the new converging market. Currently we confront the matter of asymmetric regulations between smart TV and others including IPTV or ISP. The purpose of this study, thus, is to provide the strategic, regulatory guidance and theoretical definitions on smart TV service, as one of converging services, based on a qualitative approach through subjectivity methodology. The study identifies three issues net neutrality, regulation fairness and new media and new market and proposes desirable promotion plans regarding those issues. The study draws lessons learned through a Korean smart TV case and provides directions to strategic-policy studies for future emergent converging services.

본 연구는 TV광고음향의 사운드디자인에 대한 수용자 감성반응에 관한 연구이다. 연구방법으로 영상구조에서 음향이 없는 상태와, 음악설계사운드디자인을 제시 하였을 때 수용자가 받아들이는 음향감성반응을 뇌파측정을 통한 뇌 지수(BQT) 비교 방법으로 분석하였다. 본 연구를 통하여 영상에 있어 사운드의 시청각적 감성효과가 사운드디자인설계에 의하여 달라질 수 있음을 정량적 방법으로 확인할 수 있었다.

본 논문은 디지털 TV에서 시정자가 보고 있는 동영상에서 관심 있는 화면을 갭춰하여 저장하고, 그 저장된 이미지들을 미술관이나 박물관 같이 꾸며진 환경에서 감상하듯이 다시 볼 수 있는 자신만의 이미지 갤러리를 만드는 것을 목적으로 한다. 또한, 컴퓨터 안에 있는 이미지를 PDA나 휴대폰 등에 쉽게 업로드할 수 있는 것과 같이 디지털 TV에서도 이 이미지들을 가공하거나 이메일을 통해 다른 사람에게 전달할 수 있다. 본 논문에서는 디지털 TV에 이러한 갤러리 기능을 추가하기 위한 데이터 방송 애플리케이션의 설계와 구현을 기술한다. 이 애플리케이션은 디지털 방송이 시작되면서 가능해진 본격적인 데이터 방송을 응용한 독특한 예이다. 본 논문에서는 이러한 데이터 방송을 구현하는데 필요한 요소를 기술하고, 애플리케이션을 구현하는 과정에서 해결해야 했던 문제점들을 기술한다.

Modern TV public advertisements of China began in 1986. As messages were spread and expanded to the public through TV media, the society as a whole started to accept the public advertisements and the influence of public advertisements increased ever more. Successful persuasion is an important prerequisite for realizing the effects of TV public advertisements and this study sought to examine persuasion strategy at this moment when media, messages and the audience are becoming diversified. It sought to know of the present situation of China's TV public advertisements particularly from the standpoint of Chinese and analyze persuasion strategy and usage based on the theory of persuasive communication.

In this paper, we propose an emergency wake-up alert system (EWAS) for providing accurate and rapid emergency information. The proposed system can provide an emergency wake-up alert service without an additional frequency allotment by utilizing the guard band of the Advanced Television Systems Committee (ATSC) Terrestrial Digital Television (DTV) system. The design target of the proposed system is to match the indoor reception coverage of EWAS with the outdoor reception coverage of the ATSC DTV system. To achieve this, the proposed system should be about 35.65 dB more robust than the ATSC DTV system. The simulation results show that the proposed system offers an emergency wake-up alert service supporting a data rate of up to 23 bps.

Recently, elderly populations are coming out as the first magnitude consumers. The purpose of the study is to present the basic data on the use of television media of elderly people and help developing the consumer market for the elderly people. This study was based on a survey conducted on the use of television media of Korean people over 20 years old with a thorough review of literatures published worldwide. This study revealed that the elderly consumers are more often dependent on television media than younger populations. This results will be applied in establishing a relevant promotion strategy for elderly marketing.

In this paper, we presented the concept and some methods to watch online video clips related to a TV program on atelevision which is called lean-back media, and we simulated our concept on a PC system. The key point of this research is suggesting a new service model to TV viewers and the TV industry, which the model provides simple and easy ways to watch online video clips on a TV screen. The paper defined new tags for metadata and algorithm for the model, then showed simple example using those metadata. At the end, it mentioned the usage of the model in the digital broadcasting environment and discuss about the issues which should handle as future works.

This study deals with the effects of the extension of terrestrial TV VOD holdback on the viewing behavior focusing on IPTV & digital cable TV. And this study presents the implication by analyzing a time series trend of the digital media service. Thus researcher has analyzed the VOD performance trend of IPTV & digital cable TV, based on the real data of media player's internal fact sheet. First, researcher confirmed that the repetition of the peak value goes to January and August seasonally. Also, it was confirmed that the viewing rate of terrestrial broadcasting companies is affected by the hit drama program. And researcher confirmed that the terrestrial VOD, movie and kids VOD, and terrestrial VOD purchases is falling down by analyzing a time series relationship. Terrestrial broadcasting companies did an extension of the holdback for the purpose of trying to increase the viewership of the broadcast, but it was confirmed that it was reduced both purchasing desire VOD viewing and viewing of the broadcast audience rather. Thus the researcher expect the customer familiar policy of media players in the future.
