Product Overview
Product Overview
The DEXIN NDS3218A 8-in-1 MPEG-4 AVC/H.264 HD encoder is our newest professional HD
audio & video encoding and multiplexing device with powerful functionality. It is equipped
with 8 HDMI (or SDI) channels input supporting MPEG-4 AVC/H.264 High Profile code
format & main Profile code format, and also 1 ASI input for re-mux. It can multiplex the
ASI input TS and the 8 encoded SPTS to generate a MPTS output with the inserted PSI/SI
information. 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.
