DTN-1/DTN-1t Dual channel descrambling receiver

DTN-1 designed to receive two digital transponders in DVB-S/S2 format from satellite and descramble selected programs with standard plug-in decoder modules (CAMs). Using built-in multiplexer, services from both receivers and transport stream input can be combined into output transport stream.

Unlike DTN-1, equipped with DVB-S/S2 receivers, DTN-1t has DVB-T2/T/C receivers for receiving digital terrestrial or cable broadcasts. Otherwise DTN-1t is not different from a «satellite» DTN-1. There is a multiservice BISS descrambler built-in in device’s multiplexer.
