MPEG Multi HD Mediaplex
Introduction
Video/Audio 아날로그 신호 및 Digital 입력 신호를 Digital 압축(Compression)/부호화(Encoding) 기술로 처리하여 Digital 신호 전송에
적합한 Transport Stream으로 출력하는 MPEG-2/4 AVC(H.264) HD Encoder와 Encoder에서 출력되는 Transport Stream 신호를
DTV방송에 적합한 8-VSB방식으로 변조하는 8-VSB Modulator를 결합한 4Channel Multi HD Mediaplex이다.
