ATSC Modulator System

8Channel IP to

ATSC Modulator

(NAMD-800A)

▶ 특 징

•Gigabit Ethernet Input, RJ45 interface

•TS over UDP, Unicast and Multicast 가능,

IGMP Ver.3 support

•8 Channel re-multiplexing, MPTS / SPTS Multiplexing

•정밀한 PCR Re-Stamping

•PID Filtering, Remapping 기능

•ATSC A/53 표준에 부합하는 8 채널 ATSC-T 8VSB

캐리어 출력 조정 기능

•RF 출력 주파수 범위 : 57MHz ~ 969MHz

• RF 출력 레벨 : 0dBm

• RF 출력 레벨 조정 : -30dBm ~ 0dB, 0.5dB Step

•네트워크 원격제어(NMS) 가능

•착탈식 Module Type으로 손쉬운 유지보수

NAMD-800A ATSC Modulator는 Ethernet Port로 전송된 UDP Format의 TS Stream 신호를 8VSB 로 변조하는 ATSC Modulator 로서 하나의 Module로 최대 8개 Channel의 TS Stream 신호를 동시에 변조할 수 있는 장비이다
