UMH160R Receiver/Decoder

UMH160R can receive digital signals from various of inputs (DVB-S/S2, DVB-C, DVB-T/ISDB-T, ASI and IP), decrypt, process/select programs to various outputs including CVBS, HDMI, SD/HD SDI, ASI, TS/IP and QAM/OFDM. It supports multi-channel descrambling, multiplexing, external table/data insertion, transcoding and transmodulating. It also supports video decoding with two audio channels. With remote web-based management interfaces, it is ideal to support advanced content distribution, real-time signal conversion and transmission via IP. 

Features:

  • Receive MPEG-2/H.264 signals from two transponders (DVB-S2) or two frequencies (DVB-C, DVB-T or ISDB-T).
  • Decrypt multi-channel programs by Conax, Irdeto, NDS, Viacess, Verimatrix, BISS-1/BISS-E or other DVB-based condition access systems via dual independent CI slots.
  • Optional four-channel Annex A/B QAM output or two-channel OFDM output, ideal for transmodulation
  • Support program multiplexing, filtering, AD/EPG insertion and cherry picking.
  • Support two pairs of audio decoding
  • Support balanced/unbalanced analog audios, GPI and cue tone
  • Optional 4 channel MPEG2 to/from H264 transcoding ( 2 for HD programs)
  • Web-based management interface
