MPEG Transcoder
Introduction
Digital Stream(DVB-ASI, IP) 신호를 입력 받아 MPEG-2에서 MPEG-4 또는 MPEG-4에서 MPEG-2로 Digital Stream Format을 변환시켜 주는 Transcoder이며, 또한 다양한 RF 방송 신호를 수신하여 Video 및 Audio Stream을 송출 하고자 하는 Digital Stream Format으로 Transcoding 할 수 있는 Professional MPEG Transcoder입니다.또한 Video 입력의 Resolution, Frame Rate, Image Enhance, Noise제거, 색상보정, 감마조정 등의 Scaler 기능을 지원한다.
