Abstract: 수신 장치(3)는 디지털 복조부(12)로부터 출력되는 압축된 디지털 신호를 디지털 비디오 및 오디오 신호로 변환하는 디지털 회로부(13), 디지털 회로부(13)로부터 출력되는 디지털 비디오 및 오디오 신호를 아날로그의 비디오 및 오디오 신호로 변환하는 비디오/오디오 출력 회로(14), 및 중간 주파수 신호를 오디오 중간 주파수 신호로 변환하는 중간 주파수 처리 회로부(15)를 구비한다.  이에 의해, 비디오 디스플레이 장치(4)의 회로 기판에는 디지털 신호 처리를 위한 비디오/오디오 처리 IC를 더 이상 실장할 필요가 없어지기 때문에, 간단한 구성의 비디오 디스플레이 장치를 이용해서 수신 시스템을 실현할 수 있다．

Abstract: A snorkel duct structure is provided to filter foreign material and to reduce noise and vibration by installing noise prevention material with a pore or a diaphragm on an inner wall and reducing speed of inhaling outside air. A snorkel(100) duct structure is formed like a hexahedron with one surface opened and has an extension part(101) connected to an air duct on a bottom surface. Noise prevention material(110) is attached to both side surfaces, an upper surface, and a rear surface. The noise prevention material is made of non-woven fabric, sponge, fabric, paper, or felt, with a pore. The noise prevention material is installed at a certain distance from an inner wall. A snorkel can have ribs protruded at a certain interval on an inner surface.
