초록

본 논문에서는 기존 Multi-Vision System(MVS)에서 지원되지 않았던 N-스크린 서비스를 구현하기 위한 시스템 구조와 시스템과 사용자간의 인터랙션 방안을 제안한다. MVS의 N-스크린 서비스는 사용자가 다양한 단말들을 사용하여 자유로운 위치에서 MVS 디스플레이를 제어하고 MVS의 컨텐츠를 연속성 있게 공유할 수 있게 한다. 본 논문에서는 MVS에서 N-Screen Service 의 인터랙션 서비스를 지원하기 위해 관리 서버와 에이젼트를 도입한 서비스 방안을 제안한다. 그리고, 어플리케이션 실행, 서비스 제어를 위한 사용자 인터렉션 그리고 N-스크린 서비스를 지원하기 위한 비주얼 캐스팅 등을 위한 몇 가지 프로토콜의 예를 제시한다. 추가적으로, N-스크린 세션 분할, 그리고, 위치에 구애 받음 없이 사용 중인 사용자의 다양한 단말을 사용한 메타데이타 컨텐츠 실행 등을 위한 프로토콜을 사용한 N-스크린 서비스 시나리오도 예로서 기술한다. 시뮬레이션 결과는 제안 된 메커니즘의 적합성과 성능개선을 보여준다.

In this paper, we propose the architecture and user interaction mechanism to implement N-Screen services on Multi-Vision System (MVS) that are not supported in existing systems. N-Screen services enable users to control the MVS displays through any of their devices and share contents among MVS displays and user's active-devices with service continuation at any location. We provide N-Screen interactive services on MVS by introducing N-Screen interaction & session management server and agent. Furthermore, we present some examples of the protocols such as application launching, user interaction for service control and visualcasting to support N-Screen services. In addition, we explain the N-Screen service scenarios for providing split sessions on user's active-devices and launching metadata content on any of his devices at any location supported by these protocols. The simulation result demonstrates the feasibility and performance improvement of the proposed visualcasting mechanisms.
