4 Channel HD Encoder & Modulator

Latency 1100ms

Chroma Format 4:2:0

Introduction

As a representative model of CASTWIN, it is a new released evolutionary product. It is the professional and hght class product combining low delay high definition encoder and ATSC(8-VSB) modulator. It enables to 4 channels encoding as well as modulating performance and to the direct digital frequency conversion after advanced compressing and encoding for suitable digital transmission. Also it is very easy to control with Hi-class front VFD.
