The DT-302 (dual) modules are digital satellite receivers compatible with DVB-S and DVB-S2 standards. They can receive a satellite transponder and deliver the transport stream in the form of TS-ASI.
Each satellite receiver has two identical TS-ASI outputs. This is because satellite transponders can typically allocate a higher number of services than DVB-T mutiplexes and therefore more than one COFDM modulator may be required if we want to deliver all services of the transponder to the TV distribution system.
Each satellite receiver allows inserting a Conditional Access Module (CAM). Several types of CAM can be used for de-encrypting one or more of the available encrypted programmes and being distributed (see DT-902).
