본 논문은 ATSC2.0 기반 8-VSB/MH 융합형 3DTV (A/104 Part 5 Service Compatible 3DTV using Main and Mobile Hybrid Delivery, A/104 part 5) 방식의 서비스 커버리지 및 음영지역을 예측할 수 있는 측정 및 분석시스템 개발에 대하여 기술 한다. ATSC2.0 기반 고정/이동 방송시스템은 8-VSB 로 전송되는 고정 TV 방송서비스(좌영상 전송)와 ATSC-MH 로 전송되는 in-band 모바일 방송서비스(우영상 전송)를 모두 수신하여 좌/우영상의 재생 및 동기화를 통해 융합형 3D 영상을 복원하게 된다. 따라서 융합형 3DTV 수신기는 고정 및 모바일 방송신호를 모두 수신하여야 융합형 3D 영상복원을 할 수 있으며, 방송사 입장에서 서비스 커버리지 측정을 하기위해서는 8-VSB 및 ATSC-MH 신호의 수신여부를 모두 측정하여야 한다. 본 논문에서는 이와 같은 RF 수신전계강도 파라미터 및 GPS 정보등을 실시간으로 모니터링하여, 시스템 사용자에가 융합형 3DTV 서비스 커버리지 측정 및 분석을 통해 서비스를 위한 RF 방송망 셀 구성 및 음영지역을 예측할 수 있는 ATSC2.0 융합형 3DTV 서비스 커버리지 분석기 구현에 대한 내용을 기술한다.
