Product Overview
DEXIN NDS3226SA multi-channel encoder is our newest professional SD audio & video encoding and multiplexing device with powerful functionality. It adopts the slot structure with one device supporting maximum 3 DX3226SA modules. Each module can support 16 channels and work standalone. It is equipped with 16/32/48 CVBS channels input. It can multiplex the 16/32/48 encoded TS to generate a MPTS and 16/32/48 SPTS output through GE output port and one MPTS output through 1 ASI output ports. 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, satellite and terrestrial digital TV, etc.
