Abstract

In this paper we introduce augmented broadcasting service scenarios which combines augmented reality service with broadcasting environment. As the broadcasting environment is different from mobile service environment, there are many restrictions in developing full AR services in TV. However TV has strong benefit of large screen, high quality contents, advanced user interface for motion and voice, and smart TV applications, which means that they will enhance the possibility of success for augmented broadcasting service. This paper proposes metadata structure containing information for augmentation region, time, augmented contents, and registration information for natural composition. We also implemented test bed system comprised of authoring server, broadcasting server, and user terminal for verifying metadata in broadcasting system.

본 논문에서는 최근 모바일 디바이스에서 제공되고 있는 증강현실 서비스를 방송환경에 접목할 수 있는 서비스 시나리오에 대한 소개와 이를 실현하기 위한 증강방송 메타데이터에 대하여 소개한다. 방송환경이 모바일 환경과 다르기 때문에 완벽한 증강 서비스를 제공하는데 있어서 한계가 있다. 한편 TV의 대 화면과 양질의 TV 프로그램, 스마트TV로의 발전에 따른 웹 환경 지원과 모션/음성 인식 인터페이스, 그리고 스마트TV 애플리케이션의 등장은 증강방송의 가능성을 한층 높이고 있다. 이를 가능하게 하기 위하여 증강방송 메타데이터를 설계하였으며, 증강방송 메타데이터는 증강영역 및 시간, 증강 콘텐츠, 정합 정보 등을 포함한다. 증강방송 메타데이터의 검증을 위하여 메타데이터 저작서버, 증강방송 서버, 그리고 방송단말로 구성되는 검증용 테스트 베드 시스템을 구현하였다.
