Product Overview

ZJ3214B multi-channel encoder is our newest professional SD audio & video encoding and multiplexing device with powerful functionality. It is equipped with 4/8/12 CVBS or SDI channels input supporting MPEG-2, MPEG4 AVC/H.264. It can multiplex  the encoded TS to generate IP output through GE output port. It adopts the slot structure with one device supporting maximum 3 DX214B encoder modules. Each module can work standalone. In conclusion, its high integration and cost-effective design make this device widely used in variety of digital distribution systems such as CATV digital head-end and terrestrial digital TV, etc.
