This study aims to analyze the current status of records management in local broadcasting stations. To that end, it conducted interviews with personnels in charge of keeping records in KBS in J province, MBC in J province, and 2 local commercial broadcasting stations as well as KBS headquarter. The findings show that the local broadcasting stations keep digital files of born-digital broadcast records in a server in a relatively systematic way. However, they never digitalized their analog records and do not even know the exact volume of total records they own. In addition, they have significant difficulties in preserving and utilizing broadcast records because of outdated preservation facilities and information retrieval systems. Based on the findings, this study suggests ways to improve current broadcast record management such as preparation of record management guidelines, construction of an inventory for owned records, digitalization initiative, and provision of metadata education for PDs, etc.

In Korea, cable television(CATV) broadcasting has begun in March, 1995. This Paper aims at examining the location of CATV broadcasting station, and demand density(numbers of viewer houshold) of broadcasting area, and at clarifing the factors affecting subscription. The results are as follows: The number of CATV stations is 54 in 1996, and these CATV stations are mainly located in larger cities. The correlation between the number of established or planned CATV station and the number of household is very high. In sphered broadcasting area Permitted in 1997, the location of CATV station is about 73,000 household and 230,000 persons in the minimum values of household and population, and diameter of sphered broadcasting area is 40.6 km in mean. The factors affecting subscription rates of CATV are median age and supply rates of apartment of each dong in Chongju city and each myun in Chongwon county. The correlation between subscription rates of CATV and supply rates of apartment appears higher than correlation between subscription rates and median age other factors based on residual analysis of regression equation are established period of transmission network of CATV and acceptance attitude of dwellers.

본 논문에서는 방송프로그램 저작권 식별관리를 위한 방송프로그램의 Video Signature와 국가표준콘텐츠식별 체계인 UCI(Universal & Ubiquitous Content Identifier)와의 연계 방안을 제시한다. Video Signature는 UCI와 같은 식별자의 인위적인 부여 과정이 없더라도 비디오 콘텐츠 자체에서 직접 특징정보를 추출할 수 있기 때문에, 이미 배포 유통된 콘텐츠에 대해서도 식별 확인이 가능하다. 따라서, 본 연구에서는 UCI 표준식별체계와 방송프로그램의 Video Signature와의 지속적인 연계를 위하여, 바이너리로 표현된 Video Signature가 포함된 UCI 응용 메타데이터를 정의한다. 그리고 UCI 표준식별체계 기반의 Video Signature 전송 및 관리 메카니즘에 기반한 방송프로그램의 저작권 식별관리 시나리오를 제시한다.

본 논문은 디지털 방송 프로그램 진행 중 비디오의 특정 시점에 동기화된 특정 객체의 위치정보를 표현하는 data stream을 생성하고, 그 시점에 해당 위치 정보를 해석하는 해석기에 관한 것이다. 현재의 상용 스트림 생성기는 디지털 방송 표준에서 권고하는 스트림 이벤트의 발생 시각과 셋톱박스에서 디코딩 시에 사용할 참조값을 적절하게 생성하지 못하고 있다. 또한, 셋톱박스에서 동작하는 애플리케이션(Xlet) 역시 STC(System Time Clock), PCR(Program Clock Reference), NPT(Normal Play Time) 등의 시간값을 적절하게 읽어내지 못하고 있다. 더욱이, 현재의 디지털 방송 표준에서는 영상 내 특정 객체를 위해 정보를 제공하는 데에는 한계가 있다. 따라서, 본 논문에서는 다양한 연동형 디지털 방송 프로그램 제작을 위해 비디오의 특정 시점에 동기화된 객체의 위치정보를 표현하는 data stream을 생성하는 방법과, 동기화된 데이터를 처리하는 애플리케이션에 대해서 설명한다.

In this article, Channel 4 in Britain is the main theme since its alternative broadcasting system can shed the light to the Korean case. Korea is getting into the era of multimedia and including webcastings there are over thousands channels are available. However the infra-structure fur the broadcasting contents never seems to be matured to match its need. Instead Korean production system is rather vertically integrated into the Networks(KBS, MBC and SBS) which oligopolise the broadcasting in terms of supply. Even though 'Program Quota Regulation' has been established under the new Broadcasting Art(1999), the old habits die hard and still the independent producers have the unfair relationships with the Networks. Under this circumstance, Channel 4 can be the good example to show how well the alternative system can serve to the diversity of broadcasting and the taste of the minority. Channel 4 took almost 20 years to establish since there were enormous amount of debates about its public missions, ideal broadcasting system, whom it should serve for, etc. between all the social sectors including the independent producers. The social agreement was reached on the point that the new broadcaster should not produce but publish and it is called the 'publishing broadcaster'. In this sense, it can be managed effectively with comparatively little fund and at the same time, it can always have all different sorts of contents as well as genres very freely through 'commissioning process' or buying programs from even the most innovative producers. The 'commissioning process' is one of the key points which makes the Channel 4 so unique. The commissioning process is literally open to anybody, in particular, to the small scale producers with much innovative ideas. Channel 4 will support financially as well as with facilities and human resource to produce the program once after their program idea is accepted by the commissioning editor. Even better side of Channel 4 is about their financial success. From the beginning, the 'funding formula' helped in great deal to make the Channel 4 doing all sorts of innovative experiments. The history of 'funding formula' and its contribution are explained in the article, too. With all this effort, the article is hoped to bring discussion about the alternative broadcasting system which might help to prepare the new era of broadcasting.

Because the movie has the characteristics of a cultural product where experience is important, a promotional strategy is used to convert viewers into movie audiences by providing indirect experiences of movies through professional movie information programs. Considering that the movie information program is a strategic publicity medium that raises the audience's intention to watch a movie, a study on the data service that provides useful additional information to the viewer in conjunction with the movie information program is meaningful. Against this background, this study contains the core research contents in the development of data service linked with movie information program. Specifically, additional information of the movie information program was defined. And to provide the additional information to the data service, the digital broadcasting international standard DVB-SI-based additional information transmission method was devised.

TV broadcasting platform is evolving to the digital-TV, which is supporting data broadcasting service. Although the data broadcasting services (i.e., games, wether information, stock trading service) provide rich entertainment to viewers, they make the operation manners of digital-TV so complex that some viewers feel difficulty in using their TV sets. The paper tackles the problem by devising a method for constructing viewer-specific EPG configurations based on the viewers' ability of handling IT devices. The paper also propose an environment (e.g., EPG configuration transmitting method, EPG structure) that implements dynamically an EPG configuration based on the viewer's choice of EPG configuration.

It requires protection technologies to permit consumer to store a digital broadcasting content and at the same time to protect the intellectual property from illegal action. There is content encryption as one of protection technologies. In this paper, we proposed a protection scheme for digital broadcasting content that broadcasting server. Multiplexes the encryption key into MPEG-2 TS(transport stream) to be able to encrypt received TS at set top box. The proposed method is to modify PMT(program map table) for the information related encryption key and to multiplex key as TS packets. After then the encryption key is extracted from TS stream which is encrypted in set top box.
