최근 그린IT가 주요 사업으로 급부상하면서 다양한 분야에서 소비전력 저감 관련 연구가 활발히 진행 중이다. 특히, 멀티미디어서비스 발전에 따라 '국내 셋톱박스가 2,000만대 이상 보급되었으나 미사용 대기시간에도 상당한 양의 전력을 소비하여 국가 전력 수급에 많은 영향을 주고 있어 이에 대한 해결방안이 시급히 요구되고 있는 상황이다. 방송 서비스 사업자는 방송 콘텐츠의 활용성 증대, H/W교체 주기 연장 및 소비전력 저감 등의 이점으로 인하여 저전력 모드를 지원하는 셋톱박스에 가상화 서비스 제공 기술을 적용하기 위한 방법을 또한 모색하고 있다. 본 논문은 셋톱박스의 발전 방향이 하이브리드화, 고기능/복합화 함으로써 소비전력이 더욱 증가하고 있으므로 셋톱박스의 소비전력 저감을 보장하고, 가상화 서비스를 제공하기 위한 고려사항과 에너지 효율성을 보장하는 방법을 제공한다.
