Professional PC Card
The NetUP Dual DVB-T/C-
CI is being offered as a pro-
fessional DVB-C and DVB-T
PCI-e adapter and is being
primarily marketed for use
in IPTV servers. When the
adapter arrived at our TELE-
satellite test labs in an unre-
markable package, we were
a little concerned at first
when we opened the pack-
age and couldn’t find any
trace of a user manual or
quick start guide; not even
a driver CD could be found!
As it turns out, if you pay
a visit to the manufacturer’s
web site you’ll find a brief
overview of how to install
this adapter under Linux. It
is necessary to recompile
the kernel in a NetUP modi-
fied kernel version 3.0.0-
rc7. Prepared software has
to be put together by the
customers themselves. The
card is tested with tzap and
czap.
It’s obvious that we’re not
dealing with a consumer
product here but rather a
professional product. Linux
experience is required so
that the card can even be
recognized by the operating
system.
The manufacturer wasn’t
neglectful in including a
written description, it’s just
a simple consequence of
the brand new hardware
components that are used.
The chips are very new
and boast high power in a
small space: A DVB-C or
DVB-T signal can be placed
on either of the two tun-
ers. There are also two CI
slots. The internal compo-
nents consist of a Conex-
ant CX23885 that can han-
dle two MPEG transport
streams and works with
an integrated Sigma-Delta
ADCs with 4:2 MUX.
There’s also an extreme-
ly energy efficient STM
STV0367 ultra compact
combination DVB-T/C single
chip receiver on board. This
comes with 6, 7 or 8 Mhz
bandwidth as well as QPSK,
16 QAM and 64 QAM modu-
lations. 16, 32, 64, 128 and
256 constellations are sup-
ported in DVB-C mode.
The tuners are Xceive
XC5000 Silicon tuners that
don’t need any kind of me-
tallic shielding thus making
them easier to incorpo-
rate onto the circuit board.
These tuners support all
the TV standards and have
exceptional sensitivity even
with weaker signals. For the
CI slots an Altera FPGA is
available. This chip is a pro-
grammable processor and
by that we mean the soft-
ware based arrangement
of the function structure.
This makes it theoretically
possible to modify the CI
interface to work with new
developments.
After the installation of
the hardware in the PC, a
Linux distribution must then
be installed. For our case
we selected an up to date
Ubuntu Distribution since
it can be installed rather
