해상교통관제시스템(Vessel Traffic System: VTS)에서는 해상 사건/사고를 사후 확인하거나 해상 교통량 확인을 위해 사용하기 위한 목적으로 VTS에서 발생하는 데이터를 저장 및 관리한다. 특정 지역에 대한 장시간 교통량 확인에서는 녹화된 재생 데이터를 고속 배속으로 실행시켜 살펴보는 것이 시간 단축에 큰 도움이 된다. 그런데 일반 영상이 아닌 VTS 서브 시스템간 주고 받은 메시지와 영상이 포함된 VTS 녹화재생에서는 고속 배속을 지원하는데 자연스럽지 않은 문제점이 발생하고 있다. 따라서 본 논문에서는 VTS 녹화재생 기능이 고속 배속을 지원하기 위해 필요한 요구사항을 분석한다.
