Abstract: 본 발명은 디지털 방송 수신기에서 복수의 채널을 순차적으로 검색 시 각 검색에 대응하는 포커스 채널(focus channel)이 특정 기간마다 변경되도록 하다가 사용자의 선호 채널 또는, 기 설정된 주요 채널에서는 특정 기간보다 긴 기간 동안 멈추도록 하는 채널 검색 장치에 관한 것이다. 
     이와 같은 본 발명은 디지털 방송 수신기에서 복수의 채널을 순차적으로 검색 시 각 검색에 대응하는 포커스 채널이 특정 기간마다 변경되도록 하다가 사용자의 선호 채널 또는, 기 설정된 주요 채널에서는 특정 기간보다 긴 기간 동안 멈추도록 하여, 사용자가 복수의 채널을 순차적으로 검색 시 선호 채널 또는, 주요 채널의 프로그램 내용을 인지할 수 있도록 한다. 
     따라서 사용자는 자신이 선호하는 채널 또는, 기 설정된 주요 채널의 내용을 인지하면서도 채널을 빠르게 검색할 수 있다.
