The NDS3204I-4 4 in 1 MPEG-2 Encoder (with IP output) is a professional audio & video encoding device with powerful functionality. It adds the function of IP output SPTS on the base of common 4 in 1 SD encoder .It also has 4 channel CVBS video input interfaces, 4 pairs of unbalanced audio input interfaces and an ASI input interface, supporting MPEG-2 encoding format. This device can simultaneously encode 4 channel SD audio & video; and generate four SPTS through different IP address or IP ports; moreover, this device can decide to output one channel SPTS through the ASI port. All designs are totally comply with the MPEG-2 standard. In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as cable TV digital head-end, satellite digital TV broadcasting and terrestrial digital TV, etc.
