최근 다양한 단말기를 대상으로 동일한 미디어 콘텐츠, 애플리케이션 서비스를 제공하는 N-Screen 전략이 두드러지고 있다. N-Screen 서비스를 제공하는 방법의 하나로 단말 간 유사한 사용자 인터페이스를 제공하는 방법이 있다. 이는 사용자에게 친숙한 사용자 경험을 제공하는 장점이 있으며, 이러한 방법을 위해서는 단말 간 장면 동기화가 매우 중요하다. 기존의 N-Screen 서비스에서는 장면 동기화를 위하여, 단말 간 API 인터페이스 등을 사전에 조율해야 하는 문제점이 존재한다. 이에 본 논문은 상기와 같은 N-Screen 서비스의 동기화 방법의 문제점을 해결하기 위하여, 명령어 혹은 이벤트 중심이 아닌 자원 중심의 단말 간 통신 방법에 대해 제안하였다. 이를 위하여 장면 업데이트의 내용을 효율적으로 XML 형태로 기술하고, 전송하는 방법에 대해 연구하였다.
