4. In a second window TS
Reader Pro shows the status
of the streams and especially
interesting is the display
showing the amount of data
being inserted into the network.
5. The stream can now be
received by any computer or
IPTV receiver. We’re using the
VLC software on the computer.
“Open Network Stream…” is
opened under Media.
6. Now “UDP://@224.2.2.2:1001”
must be entered; the IP and
Port number naturally have to
match what was entered into TS
Reader Pro.
7. VLC now starts the reception
of the stream and if everything
works as it should, you’ll see
the Play button change over to
a Pause button (lower left).
8. After 1-2 seconds a picture
appears.
To receive the stream,
open up the VLC application
on another PC. Obviously,
this computer has to be con-
nected to the same network.
Under “Media” in the menu,
“Open Network Stream…”
should be selected and in
the window that appears,
“UDP://@224.2.2.2:1001”
should be entered.
If you chose a different IP
and/or port number, then
of course you’d have to en-
ter in those values. VLC will
then start and you’ll be able
to surf between all of the
streamed channels.
If it doesn’t work, check
the usual suspects: Firewall,
Antivirus, Network. In our
test center we had a com-
pletely different problem.
VLC could not receive any
UDP multicast via the net-
work even though TS Reader
Pro was able to as a receiver.
Thanks to our signal ana-
lyzers we were able to con-
firm that the stream itself
was OK; even our PC was
correctly configured.
So what was wrong? After
a few hours the culprit was
identified: Oracle’s Open
Source Software VirtualBox,
with which we tested virtual
operating systems, installed
a virtual network card that
VLC apparently gave pref-
erence to. Since the stream
would be coming from the
real network card, the screen
remained black. Deactivat-
ing the virtual network card
from VirtualBox helped with
the problem. You just have
to find the problem first…
Another inexpensive so-
lution to implement IPTV in
private homes would be to
make a Linux receiver such
as the AZBox ME or AZBox
Mini ME available to every
user.
Instead of having one of
these receivers in every
room and running the nec-
essary cable for each of
them, place the receivers in
a server cabinet and connect
them to a Quadro LNB via a
multiswitch. Each user would
be given the IP address for
