HER-2000은 8VSB Remodulator로서 ATSC(8VSB) 표준 규격에 부합하는 국내 디지털 지상파 재전송을 위한 최적의 솔루션입니다. HER-2000은 안테나에서 수신된 국내 디지털 지상파 신호를 Demodulation하여 송출 및 수신 중에 생길 수 있는 신호 내의 Ghost나 Noise를 제거하는 Error Correction 과정을 거친 후 ATSC(8VSB) 표준 규격으로 변조하여 RF로 송출하여 주는 장비입니다. 우리나라와 같이 지리적 특성상 방송음영지역이 많은 곳에서는 최적의 국내 디지털 지상파 재전송 솔루션입니다. 형식 인증 취득 제품입니다.
