UMH160 Receiver/Decoder
UMH 160 is Wellav's standard DVB MPEG-2/H.264 receiver decoder. It can receives MPEG-2 and H.264 signals in DVB-S/S2, DVB-C/T, ASI and TS/IP format and convert signals to CVBS,HDMI, HD/SD-SDI, ASI and TS/IP. It also supports multi-channel DVB decryption and BISS descrambling. With web-based network management interface, it is an ideal equipment for large scale content contribution and distribution.
Features:
- Receive MPEG-2/H.264 signals in DVB-C/T/S/S2, ASI and TS/IP (optional) format
- Decrypt multi-channel programs via two common interface slots, which support descrambling of CAS such as Conax, Irdeto, Viacess, NDS, Verimatrix/Comvenient, CTI and etc.
- Support ASI-IP & IP-ASI real time conversion and transmission for signal transmission (UMH160 IP)
- Support program edition and AD insertion via SD/HD-SDI output
- Support program filtering and timer function
- Support BISS-1 and BISS-E function
- Support online and remote configuration via network management software and SNMP integration
