Transedit does not power Unicable LNB


Recommended Posts

While trying to analyze a stream or update a transponder list (or simply trying to tune a transponder) the application doesn't power my unicable LNB. I have to turn on another receiver and then I am able to do anything with Transedit. The similar situation is in DVBViewer but there is option Retune on missing stream after (sec.) and it works with this parameter set to any value > 0. But in Transedit there is only choice Retune attempts which in fact doesn't help much in such a case.

Here it works flawlessly with an Inverto Unicable LNB and several DVB devices. It's up to the DVB device driver to switch power on in time.


Issues like this depend on the DVB device, the outdoor equipment and how they interact. Please attach the file TransEdit.ini from the configuration folder.

I use Inverto Unicable II lnb (IDLU_32UL40-UNBOO-OPP) with TT-budget S2 4200 dual tuner card where unicable lnb is connected to the second tuner. There is a universal lnb with diseqc actuator connected to the first tuner. Maybe this combination makes such problems but doesn't matter whether I disable first tuner or not, I cannot get unicable lnb working. But As I wrote only in transedit, DVBViewer can handle this.

That's a relabeled DVBSky device. DVBSky devices usually switch the LNB power off while they are unused. As soon as an application starts using them the LNB power is switched on again.


Issues are frequently caused by lazy switches that need a long time for power up, which means, they may not be ready to receive a DiSEqC signal when it is sent. Please try the following steps:


(1) Open the Positioner Console in TransEdit

(2) Select "TT-budget S2_4200 DVB-S/S2 Tuner 2" as device (the one connected to the Unicable LNB)

(3) Click the "Go to Preset" button in the positioner window. This will let TransEdit send the corresponding DiSEqC command via the selected device, which means, the device will be initialised and switch the LNB power on (the DiSEqC command is meaningless in this case). After that the Positioner Console will keep the device in an active state as long as the window is open.

(4) Try if Unicable works.


If it works we can try some tweaking in TransEdit.ini that (hopefully) will fix the problem.

This works. Yes, it looks like similar "retune on fail" tweak in DVBViewer works the same way. It seems that I need that analyzer has to wait until LNB power is ready or not to switch off the lnb while application is open (to be able to use Restart of the analyze).


Edit: I tried last situation (to restart analyze) but it doesn't work once it failed before. I have to open it when the power is ready otherwise it won't start.

Regarding your TransEdit.ini, [Hardware] section:




is wrong. The value must be =1 for both tuners. It's a bug in our hardware database. This flag does not control the device behaviour, but informs TransEdit about how it behaves. Please correct it.


Additionaly you can try to increase




to 2 or even 3. The value specifies how many times DiSEqC commands are sent. Repeating them may fix the "lazy switch" problem.


Please note that TransEdit must be closed while TransEdit.ini is changed. The tweaks can also be applied to DVBViewer Pro in the file hardware.xml (and to the Recording Service in config\svchardware.xml if it is installed) by adding a line


<entry name="AutoLNBOff">1</entry>

for both tuners and changing the DiSEqCCount entry if it proves to be successful.

I have added all to the proper configs. I had to set DiSEqCCount.1 = 4, but still analyzer starts 50/50. It means one time yes and then no in accidental order. Increasing of this number did not bring further improvement. But I can live with this situation, the most important thing is that I can run Analyzer Independently from the other devices. Thank you.

      When I play this stream: https://www91.zippyshare.com/v/HpXZhE2M/file.html and try to run Teletext/Subtitle Analyzer on PID 8125 (Teletext subtitles for channel WP) - TransEdit will freeze, need to kill it.
      I think this is something new, started to happen on 4.2.4, might be related to this fix, but not sure...

      Dass ich nach einem Rechnerneustart stets die Hardwareerkennung ("Geräte suchen") in DVBViewer Media Server neu starten muss ist zwar ärgerlich und kann bein einem automatischen Neustart schon mal zu unangenehmen Überraschungen führen, aber damit kann ich irgendwie klarkommen.

      Nicht wirklich klarkommen kann ich aber damit dass gefühlt ohne Vorwarnung und mitten im laufenden Betrieb ein oder mehrere Tuner "vergessen" werden sodass nicht alles aufgenommen wird. Die Einträge erscheinen dann rot und ich muss die Geräte dann neu suchen und denen stets einen Unicable-Kanal zuweisen denn das hat der DVBViewer Media Server dann stets auch "vergessen".

      Und man kann das auch nicht "on the fly" korrigieren, weil dann laufende Aufnahmen unterbrochen werden.

      Wenn alle Stricke reißen: könnte ich mir ein externes Tool bauen welches das ausliest und ggfs wieder repariert? Gibt's auch für den Media Server ein API?

      I have problem with TransEdit v. and ATSC 8VSB WinTV-HVR 950Q tuner.
      I don't see "Bandwidth" option anymore and I have error "Invalid or incomplete input".
      For example, in TransEdit v3.9.8.0 I can choose "bandwidth" and no problem to add channel.
      Please check attached screenshots for both versions.
      I'm using Windows 10 x64.
      Please suggest.

      After a lot of time requesting the Streaming button in the TransEdit tool, finally the last version 4.2.1 has it! THANK YOU! :-)
      Now, I have another suggestion. If you use SAT>IP servers as your tuners, you know for sure that a lot of servers doesn't support the Full Transport streaming. Yes, almost all support "pids=all", and this it's great. However, when the TS has a high bandwidth, or it goes over a specific bitrate, in this case the resulting RTP streaming has a lot of Continuity Errors. This, isn't a problem for the internal Analyzer of the TransEdit, as the PSI tables can be readed multiple times. However, if you like to do an streaming, this can be a problem.
      So, here it's my suggestion: At time, when you select with the mouse multiple pids in the Analyzer and you start the streaming (CTRL+S), then you're sending only the selected pids. And this it's great! Thank you! However, the TransEdit are in fact receving the full TS. So the filtering it's internal. But, if you include in the configuration some option, it should be possible to request to the tuner to only send the selected pids. And when the streaming stops, or some change occurs in the pid list, then update the list (and when no streaming, then restablish the "pids=all").
      This will be a must have for SAT>IP servers! With this any external tool can be used for TS analysis, using the TransEdit as a TUNER.
      Please, consider it.

      Hallo zusammen,

      laut Information des Herstellers Hauppauge ist die WinTV-Box für den Unicable-Betrieb geeignet, wenn als Software der DVBViewer verwendet wird. Daraufhin habe ich den DVBViewer Pro gekauft und installiert.
      Die Installation der WinTV-Box verlief ebenfalls problemlos. Sie wird im Gerätemanager als Hauppauge WinTV-NOVA SAT (Model 139100) erkannt und mit dem Status „Das Gerät funktioniert einwandfrei“ angezeigt.
      Seit 3 Wochen gelingt es mir jedoch nicht, Sender mit dem Sendersuchlauf zu finden und die mittels Button „Senderliste laden“ geladenen 436 (free) bzw. 1015 (all) Sender „abzuspielen“, d.h. kein Bild, kein Ton, keine EPG-Daten.  

      Dazu habe ich den DVBViewer x-mal deinstalliert und wieder neu installiert, verschiedenste Veränderungen bei den Empfangseinstellungen (LNB-Typ, DiSEqC) und bei den Geräteeinstellungen/Hardware-Optionen (Unicable- Kanal und Frequenz) vorgenommen, wobei die Meldung „Dieses Gerät ist nicht komplett Unicable tauglich. Fortfahren?“ erscheint und nur mit Klick auf Unicable-Button+Strg geöffnet werden konnte.
      Bei einem der vielen Versuche wurden dann zuerst 2 und mit anderen Einstellungen noch 6 weitere Sender (spanische, französische) gefunden, ohne Bild und Ton zu haben.
      Unter Optionen/Hardware wird die Box als „Hauppauge Model 139xxx SAT Tuner“ erkannt (s. Bild_01 Optionen_Hardware)!

      Beim Sendersuchlauf wird das Gerät als „Hauppauge Model 139xxx SAT Tuner“ erkannt (s.Bild_03 Sendersuchlauf).

      Die Medienwiedergabe (.mp4- bzw. .mp3-Dateien) funktioniert aber im DVBViewer.

      Zum Test, ob der Anschluss/das Kabel funktioniert wurde ein digitaler TechniSAT-Receiver S2 angeschlossen. Alle auf dem Receiver eingestellten Sender wurden auf dem angeschlossenen Fernseher mit Bild und Ton angezeigt.

      Meine Suche nach Lösung des Problems im Handbuch und bei DVBViewer Wiki blieb erfolglos. Im Forum, in dem bereits eine Unmenge ähnlicher Probleme abgehandelt wurde, konnte ich die für mich zutreffende Lösung nicht finden bzw. brachte nicht den gewünschten Erfolg. Da ich nicht mehr weiter weiß, bitte ich auf diesem Weg um Hilfe und Unterstützung durch die Community.
