Abstract

This paper is a study on the implementation of MAM(Media Asset Management) to utilize UHD contents as high quality broadcast material. The implementation method of this paper is to separate MAM roles with content management functions and transmission workflow functions from workflow, metadata and system interface related work, which are divided into core MAM and MAM-Ex structure. Through the method proposed in this paper, we improved the content management method by applying the page menu method to the material metadata modification and applying the template method to the material structure API. In addition, the storage of UHD material and the configuration of the component server are pooled without any distinction of channels, thereby enhancing the security of UHD transmission assets by minimizing the movement of contents together with broadcasting material protection.

본 논문은 UHD 콘텐츠를 고품질 방송소재로 활용하기 위한 MAM(Media Asset Management) 구현에 관한 연구이다. 본 논문의 구현방법은 워크플로우, 메타데이터, 시스템 인터페이스 관련 작업을 콘텐츠관리기능과 송출워크플로우 기능으로 MAM 역할을 분리하여 코어 MAM과 MAM-Ex 구조로 이원화하였다. 본 논문에서 제안하는 방법을 통해 송출소재 관련 메타데이터 수정은 페이지 메뉴 방식을 적용했고, 소재 구조체 API는 템플릿 방식을 적용함으로써 콘텐츠 관리방식을 개선시켰다. 또한 UHD 소재 스토리지 및 컴포넌트 서버의 구성은 채널 간 구별없는 풀(pool) 방식으로 통합하여 방송소재 보호와 콘텐츠 이동을 최소화하여 UHD 송출자산의 보안성을 강화하였다.
