in SMPTE mode and changes
the entry fields for frequen-
cy and modulation mode in
the entry possibilities for IP
address and port of the re-
ceived data stream.
Naturally, the data can also
be used in other applications
and programs that can work
in Unicast or Multicast mode.
Using the web interface, the
transmission mode can be
set to RTP (Real Time Trans-
port Protocol) or UDP (User
Datagram Protocol) and the
parameters TP per IP and TP
size can also be set.
As part of our tests, we at-
tempted to receive the data
stream sent by the DTE-3137
using the very popular VLC
Player (
www.videolan.org)
on a Mac and a Windows PC;
as expected, it functioned
without any problems.
Regardless of which mode
was selected, the complete
transport stream is always
available on the DTE-3137’s
DVB-ASI output so that, for
example, it can be passed
on loss-free to a Re-Multi-
plexer or other professional
DVB data stream processing
equipment.
The LCD display on the
DTE-3137
continuously
shows information on the
status of the currently re-
ceived transponder (signal
level, SR, SNR and BER); it
allows a technician to moni-
tor the signal reception di-
rectly on the hardware.
A special section in the
DTE-3137’s web server
makes it possible to update
the firmware to the latest
version once it has been
downloaded from the manu-
facturer’s web site. In addi-
tion, critical DTE-3137 status
information is continuously
available via the web in-
terface such as the current
hardware revision, the cur-
rently installed firmware,
the current IP address or the
connection speed of the net-
work. By the way, if the net-
work doesn’t have a DHCP
server with automatic IP ad-
dress recognition, it can, of
course, be entered manually.
For our tests we put the
DTE-3137 through several
days of continuous opera-
tion and during that time re-
corded an enormous amount
of data via satellite (several
terabytes). And just as we
expected, the DTE-3137
worked perfectly without
any errors or crashes. At the
same time, the transponder
streams were consistently
transmitted to our PC with-
out any interference. Even a
simulated power failure did
not disturb the DTE-3137; as
soon as power was restored,
it went right back into ser-
vice without any interaction
by the user.
The DTE-3137 is a very
reliable DVB-S/S2 receiver
that was explicitly designed
for professional applications.
It takes the received data
and passes it on via a net-
work or DVB-ASI output.
Thanks to the two control
modes it has universal appli-
cations. For example, it can
completely record a DVB-
S/S2 transponder stream,
it can pass on a DVB-S/S2
transponder stream to other
devices, it can pass a stream
on via a network or through
the DVB-ASI output to, for
example, feed it into a DVB-
C cable network or to modify
and re-multiplex the tran-
sponder stream.
The manufacturer-provid-
ed C++ library available for
download also allows the
individual integration of all
Professional equipment with unsurpassable
features. Trouble-free operation of all fea-
tures, very easy control and configuration via
SNMP or web interface. Thanks to the down-
loadable C++ library, the user can integrate
all of the functions individually in his soft-
ware. The output of the received data stream
is carried over the network either directly to
the StreamXpert software or via Unicast/Multicast in RTP or
UDB.

available hardware features
in the personal control envi-
ronment of the user.
The built-in tuner is very
sensitive and demonstrated
in our tests that it could eas-
ily handle weak and narrow-
band satellite signals. The
automatic recognition of all
the necessary reception pa-
rameters functioned consis-
tently without any difficul-
ties.
Multiple reception tests
on, for example, TURKSAT at
42
° east, BADR at 26° east
or NILESAT at 7° west clearly
verified this to be true.
Thanks to the StreamX-
pert software as well as the
wide-ranging settings and
monitoring functions via web
interface or SNMP software,
the user can fully control the
DTE-3137 from remote loca-
tions.
