휴톤의 최신 3CH. 8VSB Remodulator는 ATSC(8VSB) 표준 규격에 부합하는 국내 디지털 지상파 재전송을 위한 최적의 솔루션입니다. HER-3000은 안테나에서 수신된 국내 디지털 지상파 신호 3채널을 동시에 Demodulation하여 원신호의 송출 및 수신 중에 생길 수 있는 신호 내의 Ghost나 Noise를 제거하는 Error Correction 과정을 거친 후 ATSC(8VSB) 표준 규격으로 변조하여 3채널의 RF로 각 각 송출하여 주며 1RU 크기로서 기존 Rack 공간의 활용도를 극대화 시킬 수 있는 최적의 비용 효과적인 장비입니다. 또한 Green Mode를 적용하여 방송이 중단 시 Sleep Mode로 전환하여 절전 효과를 가질 수 있는 장비입니다.
