8-VSB Mediaplex

DVM-1904MUX
  • 4 Channel
  • PCR Re-Stamping
  • DDS(Direct Digital Synthesis) 변조방식

Introduction

ITD, IRD, Encoder, PSIP/SI Server등에서 출력된 Transport Stream 신호를 4채널까지 Remultiplexing 처리하여 TS신호로 출력하는 Remultiplex와 DTV전송에 적합한 8-VSB 방식으로 변조하는 Modulator를  결합한 8-VSB Mediaplex이다.

Digital CATV System 구성함에 있어 다 채널 전송을 위한 System 구성을 Compact화 하는데 매우 효과적인 제품이다.
