EAN: 4260217682192 - ArtNr.:711216 - Resi Headend DVB-T
A DVB-T headend station enables (via modulation conversion) satellite TV at cascaded cable/antenna sockets.
- A DVB-T headend station can be used as a replacement for a broadband cable connection. A satellite dish is sufficient for a large number of users.
- An older coaxial cabling can continue to be used with a DVB-T headend station.
- In combination with our distribution amplifier AMP X8 and EOC 1000/EOC 2000, the existing coaxial cabling can simultaneously be used to transmit GBit network data.
- Expensive new cabling is not necessary.
- The Digital Devices headend stations allow the conversion of 16 DVB-S/S2/S2X satellite transponders into 14 DVB-T transponders. This corresponds to about 100 SD channels, 48 HD channels of good quality. Using the best reception technology, even weak signals at the edge of reception areas can be received.
- The low power consumption ~30-40 W (at full capacity) helps significantly reduce operating costs.
- Our DDM software (Windows, Linux, and MAC OS) can securely manage and monitor any number of headend stations remotely.
- Our headend stations are delivered in a robust housing manufactured in Germany.
- The small housing has dimensions of 300 mm x 164 mm x 137.5 mm.
- The fan with adjustable speed ensures adequate cooling.
- We do not use electrolytic and tantalum capacitors in our components. This benefits environmental protection and ensures much higher durability (MTBF 500,000 hours and more).
Signal Input
- Two eightfold DVB-S/S2/S2X tuners enable the simultaneous reception of 16 full DVB-S/S2/S2X transponders.
- When using Unicable® or JESS®, all 16 tuners can be supplied via a single antenna cable.
Signal Processing
- The Digital Devices headend stations convert incoming DVB-S/S2/S2X satellite transponders into DVB-T channels.
- Other sources can also be fed as uni-/multicast streams, such as the self-presentation of a hotel.
- Via the DDM software for Windows, MAC OS, and Linux, channels can be reordered and reassembled as desired.
- Depending on the configuration of the headend station, input signals from 8 or 16 tuners can be processed.
- 14 transponders are available as output.
- For encrypted channels, 4 Common Interface slots are available (No CI+).
- If a Common Interface is used in the system, decrypted channels can be fed through it.
Signal Output
- The Digital Devices residential headend stations output a DVB-T compatible data stream.
- The newly assembled 14 transponders can be assigned to any of the 96 output frequencies from 114–848 MHz.

- Hotels
- Residential complexes
- Hospitals
- Rehabilitation facilities
- Multi-family houses

4 Maximum DVB-S2/S2X LDPC bitrate is limited to 720 Mbit/s.
This bitrate is defined as symbol rate * bits/symbol, i.e., 8PSK 30 M symbols = 90 Mbit/s.
The used bitrate is dynamically assigned by the driver.
DVB-S channels do not contribute to the limit.
