사용자의 고화질 요구와 사업자의 차별화된 서비스 제공 노력의 결과로 기존의 MPEG-4 기반이 아닌 고화질 전용의 MPEG-2 화질을 사용하는 VOD 서비스가 새로운 대안으로 제시되고 있다. MPEG-2 비디오는 높은 네트워크 대역폭을 요구하는 단점이 있는 반면, 사용자에게 양질의 화질을 제공할 수 있으며 표준의 사용으로 컨텐츠 유지. 보수에 유리하다. 본 논문에서는 상용 스트리밍 서버인 nCUBE 서버와 연동하여 MPEG-2 TS 데이터를 스트리밍 하는 VOD 시스템에 대하여 설명한다. VOD 제어 프로토콜로 RTSP(Real Time Streaming Protocol)를 사용하였으며, 스트림 전송 프로토콜로 UDP/IP 방식을 사용하였다. 지원하는 VCR 기능으로는 FF, RW, STOP. Pause가 있다.
