초록

디지털 방송은 아날로그 방송에 비해 시청자의 선호에 기반한 방송 서비스를 제공함으로써, 시청자에게 개인화된 TV시청환경을 위한 기술적 배경을 제공할 수 있다. 하지만, 현재의 디지털 방송은 개개인에 따라 차별화 된 방송 서비스에 관련하여 전자 프로그램 가이드 (EPG) 나 초기 단계의 데이터 방송 정도의 한계를 보여주고 있다. 따라서, 본 논문에서는 진보된 개인화된 방송 서비스를 시청자에게 제공함으로써, 보다 시청자 개인에게 차별성과 편의성을 제공하는 방송 환경을 개발하고자 한다. 상기의 목적을 위하여, 시청자의 행위를 최소화할 수 있는 지능형 방송 시스템과 단순한 콘텐츠 부가정보가 아닌, 콘텐츠 레벨의 시멘틱(semantic) 정보에 기반한 방송 서비스들을 제안한다 지능적인 방송 시스템을 구현하기 위해, 지능형 에이전트 기술을 적용하고 콘텐츠의 시멘틱 정보의 생성을 위하여, MPEG-7 과 TV-Anytime Forum (TVAF)의 규격을 이용하였다. 콘텐츠 레벨의 방송 서비스들로써 사용자 단말에서 실시간 콘텐츠 필터링(filtering)과 개인화된 비디오 스키밍(skimming) 서비스들을 설계하였다. 본 논문에서는 제안된 시스템의 유용함을 증명하기 위하여 멀티 에이전트 플랫폼을 이용한 테스트 베드를 제작하고, 이를 기반으로 제안하는 방송 서비스들을 입증하였다.

Compared with analog broadcasting, digital broadcasting supports technical background to provide personalize the TV watching environment by offering broadcasting services that can adapt to viewers' preferences. However, current digital broadcasting shows limited services such as reservation recording, simple program guiding with an electronic program guide (EPG) on a personal video recorder system, and primitive data broadcasting by broadcasters. Therefore, the purpose of this paper is to suggest a new broadcasting environment which gives a person facility and a difference fur watching TV by serving enhanced personalized services. For that reason, we propose an intelligent broadcasting system which can minimize viewer's actions, and enhanced broadcasting services which are based on understanding of the semantics of broadcasting contents. To implement the system, agent technology as well as the MPEG-7 and TV-Anytime Forum (TVAF) are employed. For content-level services, real-time content filtering and personalized video skimming are designed and implemented. To verify the usefulness of the proposed system, we demonstrate it with a test-bed on which content-level personalized services are implemented.
