Scan checks out in the spec-
trum all of the transponders
that were found and displays
the individual reception pa-
rameters in the graphic. That
happens very quickly – faster
than any other signal ana-
lyzer that we know of. Even
more impressive is the speed
when the “Blindscan2” option
is activated. In this case the
CrazyScan Blindscan algo-
rithm is not used; instead it’s
the hardware implemented
Blindscan in the tuner. And
it’s here where the TBS 6991
shines with its high speed. All
the reception parameters of
the current satellite are listed
in record time.
The displayed graphic can
be exported in PNG picture
format, PDF document format
or SVG browser format. Un-
fortunately, the transponder
list cannot be exported in
INI format for normal TV ap-
plications. Sooner or later
the author of CrazyScan will
undoubtedly implement this
but it’s really not all that
important since CrazyScan
still has a lot more to offer.
If you double-click with the
mouse on a transponder, a
new window opens in which
the corresponding frequency
is already preset. The colored
key with the alien face acti-
vates the constellation dia-
gram. This has it all; it will
reset the reception param-
eters through the Blindscan
function and then in just a
few seconds the constella-
tion diagram will appear. The
user does not need to set the
modulation, symbolrate, FEC,
etc. Excellent!
If the production of the
constellation diagram is
stopped, the currently ac-
tive transponder can then
be streamed such that it
can be further processed by
TSReader. The result is un-
believable: now we can me-
ticulously analyze the stream
that was just determined
and even display the desired
channel using VLC. This is so
powerful that we simply have
to describe the process again
so that we can believe it our-
selves:
1) You align the antenna to
a desired satellite. Using the
Loop function and a small
span you can optimally align
the antenna with CrazyScan
and the use of the spectrum.
On the other hand, a com-
plex system can be controlled
thanks to cascading DiSEqC
commands.
2) Next initiate the scan
function across the entire fre-
quency range.
3) Continue with the Blinds-
can function. If, for example,
you find a new transponder
that you would not normally
find on this satellite, you need
only double-click on it to see
the constellation diagram
with all of its reception pa-
rameters.
4) Lastly the transponder is
streamed directly to TSRead-
er where you can then see a
multitude of information re-
garding the PIDs in the tran-
sponder.
5) From TSReader you can
further stream the desired
channel to VLC so that it can
be displayed.
It is our opinion that even
professionals will appreciate
this solution; we as DXers
are very impressed and can
now understand how some
other DXers manage to find
new feeds (and before us no
less!). But we didn’t even tell
you the best part yet! Crazy-
Scan is free!
TSReader has been around
for some time now and its
programmer Rod Hewitt was
introduced in the TELE-sat-
ellite 06-07-08/2012 issue.
This program is a transport
stream analyzer. The vari-
ous sources for the transport
stream can be incorporated
including BDA-compatible TV
cards as is the case with all
TBS cards.
In our last test of TBS DVB-
C cards (TBS 5680 and TBS
6618) we thoroughly checked
