NDS3224A low bitrate MPEG2/H.264 iptv encoder

 

Outline

 

The DEXIN NDS3224A 4 in 1 MPEG-2 H.264 SD Encoder is our newest professional SD audio & video encoding and multiplexing device with powerful functionality. It has 4 independent channels of unbalanced audio &video input interfaces, supporting MPEG-2 and H.264 encoder type. Furthermore, it can support the MPEG-1 Audio layer 2, LC-ACC, HE-AAC, and each channel can support ultra low bit-rate (0.25~15Mbps for H.264 encoding, and 0.5~15Mbps for MPEG-2 encoding). 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.
