EAN: 4260217681737 - ArtNr.: 713324 - RESI Headend DVB-C
Case-5-ASUS-Hell

A DVB-C head-end enables satellite TV (via modulation conversion) on cable/antenna sockets connected in series.
A DVB-C headend can be used as a replacement for a broadband cable connection. One satellite dish is sufficient for a large number of users.
With a DVB-C headend, an older coaxial cabling can still be used.
In combination with our distribution amplifier AMPX8 and EOC1000 / EOC2000, the existing coaxial cabling can also be used to transmit GBit network data at the same time.
Expensive new cabling is not necessary.

The Digital Devices headends allow the conversion of 24 DVB-S/S2/S2X satellite transponders into 24 DVB-C transponders.
This corresponds to about 192 SD channels, 96 HD channels or 48 UHD channels in good quality. By using the best reception technology, even weak signals at the edge of the reception ranges can be received.

The low power consumption ~50W (at full configuration) helps to reduce operating costs significantly.

Our DDM software (Windows, Linux and MAC OS) can securely manage and monitor any number of headends remotely.

Our headends are delivered in a rugged 19" 1U case of German manufacture. The small housing (440mm x 243,5mm x 44mm ) can also be used as a wall mounted housing. Up to 6 speed controlled fans provide sufficient cooling.

We do not use electrolytic and tantalum capacitors in our boards, which is good for the environment and means a much longer lifetime (MTBF 500.000h and more).

Signal input

Three eight-way DVB- S/S2/S2X tuners allow simultaneous reception of 24 full DVBS/S2/S2X transponders. When using Unicable® or JESS®, all 24 tuners can be supplied via one antenna cable.

Signal processing

The Digital Devices headend converts the incoming DVB-S/S2/S2X satellite transponders into DVB-C channels.
Other sources can also be fed in as unicast/multicast streams, such as a hotel's self-presentation.
Via the DDM software for Windows, MAC OS and Linux, the channels can be ordered and recombined as desired.
Depending on the configuration of the head-end, input signals from 8, 16 or 24 tuners can be processed.
Output signals from 8, 16 or 24 transponders are also available. For encrypted channels, 4 Common Interface slots are available. If a Common Interface is used in the system, decrypted broadcasts can be fed in via this.

Note: The regulations of the PayTV providers or the regional public broadcasters must be observed.

Signal output

The Digital Devices residential headend stations output a DVB-C compatible data stream.
The newly assembled 8/16/24 transponders can be arbitrarily assigned to the 96 output frequencies from 114 - 848MHz.

Note: our headend does not perform transrating for energy efficiency reasons, the output data rate of a TV station is the same as the input data rate.

Especially suitable for:
  • Hotels
  • Residential complexes
  • Hospitals
  • health resorts
  • Apartment houses
  • Renovation of old buildings

1) Symbolraten wurden bis 85 MSymbols/s getestet
4) Maximale DVB-S2 / S2X LDPC-Bitrate ist auf 720 Mbit / s begrenzt. Diese Bitrate ist definiert als Symbolrate * Bits / Symbol, d. h. 8PSK 30 M Symbole = 90 Mbit / s. Die verwendete Bitrate wird vom Treiber dynamisch zugewiesen. DVB-S-Kanäle tragen nicht zum Limit bei. 2) derzeit noch nicht implementiert
