Two-channel tuner descrambler DTN-1/DTN-3
The dual-channel descrambling tuner is designed to receive two digital “trunks” in DVB-S / S2 format from a satellite and descramble the programs selected from them using standard plug-in decoder modules (CAM). In the DTN-1 / DTN-3 modification, DVB-S / S2 or DVB-T / T2 / C receivers are installed to receive satellite, terrestrial or cable digital broadcasting. Optionally, it is possible to demultiplex T2-MI streams on both channels. The multiplexer has a multi-channel BISS decoder. DTN operation can be controlled and monitored both from the front panel and remotely via 100 Mbps Ethernet (WEB control).
