최근 Full-HD보다 4배에서 16배 이상 선명한 초고화질 멀티미디어 영상을 볼 수 있는 UHD TV가 인기를 끌고 있다. 또한 휴대용 단말의 카메라를 이용하여 UHD 영상을 촬영하고 저장하고 있다. 그러나 이러한 초고화질 멀티미디어 영상을 스트리밍하고 재생하기에는 저사양 PC 단말이나 모바일 단말은 자원부족으로 서비스를 제대로 받을 수 없다. 본 논문에서는 클라우드 기반의 초고화질 멀티미디어 스트리밍 서비스 장치를 이용하여 저사양의 단말에서도 고품질 멀티미디어 스트리밍 서비스를 제공하기 위하여 클라우드 가상 데스크탑 서비스 기술을 이용하여 해결한다. 또한, 본 논문에서는 클라이언트 단말과의 네트워크 환경을 고려하여 다양한 비트율을 가진 영상으로 서비스를 제공함으로써 사용자에게 높은 QoE(Quality of Experience)를 제공하는 것을 보여준다.
