Encode, 8-Input CVBS MPEG4AVC/H.264 SD, IP OUTPUT CDH8500-8M4ENI

CDH8500-8M4ENI, multi-channel encoder is our latest professional SD audio & video encoding and multiplexing device with powerful functionality. It is equipped with 8 CVBS channels input supporting MPEG-4 AVC/H.264 High Profile code format & main Profile code format. It can multiplex the 8 encoded TS to generate a MPTS and 8 SPTS output through GE output port. It adopts the slot structure with one device supporting maximum 3 CDH8500-8M4ENI 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, terrestrial digital TV, etc.
