DMB-90E Series 8/12/16/20/24 Channels professional Receiver, 4 Tuners ports per module, Up to 6 Modules in Back panel. It is integrated with tuner demodulation, which can demodulate from 8/12/16/20/24 tuners, then output the IP package through different IP address and ports. The Tuners support DVB-S/S2/T/T2/C/ISDB-T/ ATSC-T optional input, demodulate to TS and encapsulated output IP packet, IP Output Port by 256*SPTS and 4*MPTS channels. Meanwhile, it support 2*ASI independent input & output.
This is an ideal solution for environments where you have a large number of air Channel, and widely used in IPTV System, Hotel, entertainment facilities, education broadcasting systems at schools and government buildings or any kinds of Source signals convert to Cable TV broadcast System, largely cost down the source gathering of Digital TV Broadcasting system and IPTV/OTT system which based on IP construction. Being the ideal multi-channel professional receiver used for FTA (free to air) IP signal source capture from digital tuner.
