스케일러블 비디오 부호화(SVC: Scalable Video Coding)는 하나의 비트스트림 결과물로부터 둘 이상의 다중 비트율 및 해상도, 프레임율을 추출할 수 있도록 MPEG의 스케일러블 비디오 코딩 국제 표준을 준수하여 부호화한 비디오 비트스트림을 의미한다. 우리는 SVC(Scalable Video Coding)기반기술을 이용하여 하나의 콘텐츠를 통해 소비환경에 적응적인 비디오 스트리밍 서비스를 IP망을 기반으로 적용하기 위한 응용기술을 개발하고 있다. 본 논문에서는 단말로 부터 전송채널에 대한 상태를 전송받아 이에 맞게 콘텐츠를 적응변환 하고 다양한 품질의 단말에서의 스트리밍을 제공하는 SVC 미디어 서버를 관리하는 SVC 서버 관리 제어기의 설계 및 그 구현에 관한 내용이다. 이와 같이 SVC 서버 관리 제어기의 개발을 통해서 SVC의 다양한 콘텐츠 적응레벨을 설정하고 관리할 수 있다.
