Abstract

The digitalization of a broadcast has caused the oversupply of the contents in order to fit the user's needs for various broadcast services. The massive contents could not help demanding one-sided watching without considering a taste and preference of a user. This situation is enlarging the demand about the personalized broadcast service to enable user to watch broadcast contents in anytime according to surplus provision of broadcast contents. TV-Anytime standard could be a solution for broadcast service to enable users to watch personalized broadcast contents according to their preference. The paper proposes the personalized broadcasting system for authoring, receiving and transmission of TV-Anytime metadata, the detailed information about the broadcast contents so that user could efficiently search a large of broadcast contents stored in the PDR(Personal Digital Recorder)receiver under the DCATV(Digital Cable Television) environment.

개인 맞춤형 멀티미디어 시대가 도래됨에 따라 점점 더 다양한 방송 콘텐츠를 소비하고자 하는 사용자의 요구는 콘텐츠 사업자로 하여금 콘텐츠의 과잉 공급을 부추길 가능성이 높다. 다양한 매체를 통하여 제공되는 다량의 콘텐츠는 사용자에게 각자의 취향 및 선호도와 관계없이 일방적인 시청만 할 수밖에 없다. 따라서 사용자는 넘쳐나는 콘텐츠 중에서 각자가 원하는 방송 콘텐츠만 선택하여 시간과 장소의 제약 없이 시청이 가능한 개인 맞춤형 방송서비스에 대한 필요성이 요구되고 있다. 상기 필요성을 충족시켜 줄 수 있는 대안 중에 개인 맞춤형 방송 서비스의 제공을 목표로 국제 표준화된 TV-Anytime이 좋은 대안이 될 수 있을 것이다. 본 논문은 국내 DCATV(Digital Cable Television) 환경하에서 사용자가 PDR(Personal Digital Recorder) 단말에 저장된 대 용량의 방송 콘텐츠를 효과적으로 저장 및 검색하기 위하여 방송 콘텐츠에 대한 정보를 기술하고 있는 TV-Anytime 메타데이터의 저작, 송출 및 수신하기 위한 방법과 이를 실제로 구현한 시스템을 제안한다.
