Encoder MPG2 4x1 SD



Part Number : NTX2104-HI

NTX2104-HI encoder is a professional SD audio & video enconding and multiplexing device with powerful functionality. It has 4 channels CVBS video and unbalanced audio input interfaces, supporting MPEG-4 AVC/H.264 Hight Profile code format. This device can simultaneously encode 4 channels SD audio & video; moreover, it has an ASI input and can multiplex the input TS with the 4 enconded SPTS to generate a MPTS output. Also, the PSI/SI information can be inserted into MPTS output. In conclusion, its hight 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.
