Abstract

MPEG-21 has identified the need fur Event Reporting in its vision for an interoperable multimedia framework. Event Reporting is required within the MPEG-21 multimedia framework in order to provide a standardized means for sharing information about Events amongst Peers and Users. Such Events relate to Digital Items and/or Peers that interact with them. Arising from an each Event, there is the opportunity to describe what occurred. However, there are a number of difficulties in providing an accurate report about an Event. Different observers of the Event may have vastly different perspectives, needs, and focuses. They may emphasize certain elements to the detriment of others, or they may describe an Event in a way that others may find confusing. In this paper, we design how to express Event Reporting message structure and system architecture in compliance with ISO/IEC 21000-15. And we implement the system for MPEG-21 Event Reporting service.

본 논문에서는 유${\cdot}$무선망의 결합, 방송${\cdot}$통신망의 융합 등의 환경에서 디지털 아이템의 생성, 분배, 소비 등과 관련된 MPEG-21 이벤트 리포팅 서비스를 제공하기 위한 시스템을 구현한다. MPEG-21 이벤트 리포팅은 MPEG-21 멀티미디어 프레임워크에서 피어와 사용자 간에 발생하는 이벤트에 대한 정보를 공유하기 위한 표준 통신 수단이다. 본 논문에서는 방송${\cdot}$통신 융합망에서 MPEG-21 이벤트 리포팅 서비스를 구현하기 위하여 IS0/1EC 21000-Part 15 규격을 준수하는 메시지 구조 및 시스템 구조를 설계하고, 이를 바탕으로 REL, IPMP, DIME 등 MPEG-21의 다른 요소 엔진과 연동 가능한 이벤트 리포팅 시스템을 구현한다.
