General description
DRD 700 is an DVB-Quad receiver. He can be user defined equiped with 2 Twin DVB frontend boards
(DVB-S/S2, DVB-T/C or DVB-T/T2). The four independent MPEG-2/MPEG-4 SD/HD input signals are
demodulated, descrambled and are available as 4x2 ASI interfaces.
For the descrambling, DRD 700 has four DVB-CI slots, which enables appropriate CAM modules to decode
the complete transport stream. Multidecryption is available by default.
The DVB-S/S2 twin frontends allows the receiving and demultiplexing of transport streams regarding
EN 302307 Annex H.2. By using two twin frontends four transport streams can be provided at the ASI
interfaces. In total there exist 4 x 2 ASI output interfaces, two interfaces provide the same signal.
Max. four transport streams as 4 x MPTS can be provided by the IP-GbE-SFP interface. In addition the
DRD700 is able to provide 60 x SPTS data streams, in total 64 transport stream channels are available
via IP interface.
Optionally the IP-GbE-SFP interface can be used as IP input. For redundancy applications the second IP-
GbE-SFP interface is available. For both options a license key is necessary.
An additional option is Processing, inclusive Service- and PIF filtering as well as multiplexing of max. four
new transport streams from the input signals with table generation.
The device is operated locally, either via a LCD display and an additional wheel or with the implemented
web server via a web browser. A SNMP agent with the corresponding MIB is built in for the integration in
a network management system. The device is controlled via a separate LAN connection, which has a
separate IP address; thus, the device can also be accessed from a distance.
The basic version of the DRD 700 comprises:
2 internal slots for Twin-DVB-x frontend boards
2 x ASI input
4 x 2 x ASI output
4 DVB common interface for the CAM modules
2 x IP-GbE SFP interface for IP input or IP streaming
o
Dual configured for signal redundancy
o
SFP-interfaces to 100/1000BaseT Half-/Fullduplex manuell configurable
10/100 Mbit LAN interface for web browser and SNMP
Isolated / potential-free switching contacts
LCD display with wheel and status LEDs
2 Wide-range power supply units (Redundancy)
The basic device can be extended with additional hardware / software options:
DVB-S/DVB-S2 Frontends (with LNB supply and 22kHz switch signal) design, SCPC filter
DVB-S/DVB-S2 Twin-16APSK-/32APSK-Frontends, SCPC filter
DVB-T/C Frontend
DVB-T/T2 Frontend
IP Frontend (Gigabit-Ethernet) with electric / optical SFP module
Service filter, PID filter
NDS CA Decryption
