MPEG DUAL SD Mediaplex

Introduction

Video/Audio 아날로그 신호 및 Digital 입력 신호를 Digital 압축(Compression)/부호화(Encoding) 기술로 처리하여 Digital 신호 전송에 

적합한 Transport Stream을 MPEG-2/4 AVC를 동시에 출력하는 Dual SD Encoder이며 Encoder에서 출력되는 MPEG-2 (DVB-ASI)

신호를 DTV방송에 적합한 8-VSB방식으로 변조하는 8-VSB Modulator를 결합한 SD Mediaplex이며 MPEG-2(RF)와 MPEG-4(IP Stream)를 동시에 출력하는 Professional Dual SD Mediaplex이다.

또한 Video 입력의 Resolution, Frame Rate, Image Enhance, Noise제거, 색상보정, 감마조정 등의 Scaler 기능을 지원한다.
