High-end descrambling tuner DTN-1KE is designed to receive up to 4 transponders in DVB-S/S2 format (including Multistream), their descrambling using a standard plug-in modules decoders (CAM), and their multiplexing and transmission of selected services to the output transport interfaces. The presence of input TS interfaces allows multiplexing of streams from external sources. Optionally, it’s possible to demultiplex T2-MI streams. The DTN-1KE can be controlled remotely via 100 Mbit Ethernet (WEB interface). Protocol Support SNMP (Simple Network Management Protocol) allows you to monitor the current status of the device.
|Input Interfaces||1xGbE / 2xASI|
|Output interfaces||1xGbE / 2xASI|
|Number of channels DVB-S/S2||4|
|Range of symbol rate||1-45 МS/s|
|GbE protocol||DVB over UDP, Multicast|
|Management and control||WEB-interface, SNMP|
|Power supply||100-240 V АС, 50/60 Hz, up to 50 W|
4 IF inputs (4 F-connectors) for connecting 4 LNBs with an independent LNB power supply at each of the inputs. DVB-S / S2 reception, including “Multistream” (EN 302 307 Annex H.2).
|Input impedance||75 Ω|
|IF frequency range||950 — 2150 MHz|
|Input Level Range||-65 – -25 dBm|
|Modulation type||DVB-S: QPSK
DVB-S2: QPSK, 8PSK, 16APSK, 32APSK
|Symbol Speed Range||DVB-S 1 – 62 Msymb/s
DVB-S2: 1 – 45 Msymb/s
|LNB power supply||13 / 18V, 300 mA max|
|“Multistream” stream selection||1 to 1 reception channel *|
* A separate tuner is required to receive each “Multistream” stream, even if several “Multistream” streams are transmitted on the same frequency.
Descrambling of scrambled programs is carried out by CAM installed into the device. Any of the accepted programs can be selected for descrambling with any of the installed in the CAM device.
|Number of slots for installing CAM||4|
|Max Number of Descrambled Programs||Up to 20 by one CAM *, but not more than 48|
* The actual number of decoded programs depends on the type of installed CAM set by the broadcasters and the conditional access system parameters set by the broadcasters.
