MPEG-2 Mediaplex
DMP-3910MS
단종예정

Video/Audio 아날로그 신호 및 디지털 입력 신호를 Digital 압축(Compression)/부호화(Encoding) 기술로 처리하여 Digital 전송에 적합한 Transport Stream으로 출력하는 MPEG-2 Encoder와 다채널 전송을 위하여 Encoder에서 출력되는 Transport Stream 신호를 최대 12채널까지 Remultiplexing 처리할 수 있는 Remultiplex를 결합한 MPEG-2 Mediaplex이다. PSIP/SI Server와 연동할 수 있는 TCP/IP 기능과 10채널의 Encoder Module과 2채널의 ASI Input Interface를 구성하여 Multi Stream으로 송출되는 MPEG-2 Mediaplex이다.
