Outline
The DEXIN NDS3224 encoder is a professional SD audio & video encoding and multiplexing device with powerful functionality. It has 4 channel CVBS video and unbalanced audio input interfaces, supporting MPEG-4 AVC/H.264 High Profile code format. This device can simultaneously encode 4 channel SD audio & video; moreover, it has an ASI input and can multiplex the input TS with the 4 encoded SPTS to generate a MPTS output. Also, the PSI/SI information can be inserted into MPTS output. In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
