able to stream entire bou-
quets with an IPTV server
via Multicasting, make sure
you use compatible routers
and switches. To really test
the limits of the NetUP Dual
DVB-T/C-CI, we decided to
stream a DVB-T transponder
at the same time. The card
did not even blink when we
did this; it functioned per-
fectly as you might expect
from a professional product.
The NetUP Dual DVB-T/C-
CI is a professional card
perfectly suited for use
in IPTV servers. Because
of the ability to use two of
these cards in a server, the
operator can stream up to
two DVB-T and two DVB-C
transponders. Naturally, you
could also combine the Net-
UP Dual DVB-T/C-CI with a
NetUP Dual DVB-S2-CI card.
The advantage to building
your own IPTV server is that
you can customize it to the
needs of your customers. A
server like this can also of-
fer additional services such
as video-on-demand as well
as function as a DHCP server
and Internet gateway. This
type of flexibility is rare with
broadcasting equipment.
should set themselves apart
with this IPTV technology
since it has been more and
more playing a key role when
it comes to community-
based systems, multi-family
homes and hotels. A single
cable can provide IPTV, In-
ternet and VoiP telephone.
This card is not only meant
This software doesn‘t cost
anything to use and can be
loaded as source code or it
can be installed as a com-
plete package for most Linux
distributions. Aside from
that, Multicast, not Unicast,
is used to provide the IPTV
stream to large networks.
In this case the entire IPTV
stream is available in the
network and each client is
able to access this stream.
In order for this to work, the
network infrastructure must
include routers that can han-
dle Multicasting.
In order to test an actual
professional configuration
with Multicasting, we took
an entire DVB-C transpon-
der and streamed it into our
network with our own home-
made IPTV server with the
IPTV protocol “RTP”. This
had a real “broadcasting
feeling” to it! We were able
to open all 12 channels at
the same time on our PC.
One thing though, our switch
gave us some problems; as
it turns out, it wasn’t really
compatible with Multicast-
ing. If you really want to be
vide two individual adapters
that would support not only
DVB-T and DVB-C, but per-
haps also Mini-ITX mother-
boards as well. These come
with one PCI-e slot, if any at
all; up until now they weren’t
a very popular choice to use.
This all changes with the
NetUP card. Throughout our
entire test in which we put
the card through its paces,
there were no stability or
heat problems. It’s clear that
this card was designed for
long-term use.
We were very impressed
with the capabilities of the
NetUP Dual DVB-T/C-CI!
for professional applications.
It would also play an inter-
esting role in the set up of
a compact multimedia center
because it would take up only
one PCI-e slot and yet pro-
