MPEG-2 SD Encoder & Modulator

Latency 800ms

Chroma Format 4:2:0

Introduction

As a representative model of CASTWIN, it is a new released evolutionary product. It is the professional and high class product combining Ultra low delay standard definition encoder and ATSC(8-VSB) or QAM modulator. or DVB-T Modulation. It shows advanced modulating performance after advanced compressing and encoding for Suitable digital transmission. Also it is very easy to control with high class front VFD.
