What to do if tuning details have changed? (1 Viewer)

[crackdown]

Thanks, indeed that list worked out for me!

Great to hear I could help you out! You're in luck because now you can always find the new channels in a frequency change. Would you mind posting your edited xml file in the developers section so it can help out other users?
Now lets hope someone can help me on the topic above....

Q: What to do if tuning details have changed?
A1: Find details of the change on the internet, TV or STB.
A2: Do an NIT scan.

I think he came up with that idea himself, he has other issues with actually finding the changes

Well then I don't understand the question.
Need more specific information about exactly what aspect of the "changes" people want to be able to find (and why).

Tuning parameters for 9003 have changed as well. How do I make a new XML?

It would be much nicer if TVServer would detect and correct this automatically. TVHeadend doesn't have any problem with changing transponders.

OK let me try to be more specific. Every now and then ZIGGO changes the frequencies of their transponders. (Cable TV) Last week they changed tp 33 with the channels HBO HD 1,2,3 and Filmnet Premiere.
In this case normally you would do an advanced scan, and tick the option search for transponder list. This however did NOT work: the scan did find 33 transponders, but could not find the exact frequency of tp 33 with the channels that dissappeared because of the change.
So in this case I had to rely on info published on the internet, and do a scan with tvsource, a program wich did find the correct transponders.
So my questions is: Is there a way to find the exact frequencies of the actual transponders? A NIT scan won't give me the exact frequencies of will it? The reason why I want to find these transponders: I need them to find all the channels available.
What kind of scan do I need? I hope its a bit more specific now.

I found an old topic wich covers my needs as well but was never replied:

Okay... but I still don't understand what you mean "changed". This is important because I can't really give you good advice unless I can understand this.
So, were these channels added (ie. completely new)?
Were they moved from another transponder?
Did the frequency of transponder 33 change?

In this case normally you would do an advanced scan, and tick the option search for transponder list.

Yes. To be clear that is an NIT (network information table) scan.

This however did NOT work: the scan did find 33 transponders, but could not find the exact frequency of tp 33 with the channels that dissappeared because of the change.

Sorry but I don't understand this either.
What do you mean by "could not find the exact frequency"?
Also what do you mean by "channels that disappeared"?

So my questions is: Is there a way to find the exact frequencies of the actual transponders?

Yes, of course.
When you do an NIT scan, TV Server first scans for transponders and then scans for channels on each of those transponders. You should be able to see the transponder details in the output after the scan.
If not you can also check the TsWriter log file after an NIT scan.

1. Open TV Server configuration.
2. Click "open log directory" in the top left corner.
3. Open the TsWriter.log.
4. Look for entries like "cable NIT: frequency:XXXX modulation:X symbolrate:XXXX" (there are similar entries for satellite and DVB-T/T2).

I only have access to DVB-T and my provider sets the frequencies to zero so I can't give a good example, but it should be quite obvious.

...but in any case I still don't understand why this is necessary. You said:

The reason why I want to find these transponders: I need them to find all the channels available.

Well, as mentioned above the TV Server NIT scan first finds the details for all transponders, and then it scans each of those transponders for channels. Finding all the channels available should not require you to care about the exact frequency details (exception: you need to know one frequency in order to do the NIT scan).

A NIT scan won't give me the exact frequencies of will it?

How to answer this.
To start with I should say again that I don't understand why you want to know about the frequencies, but putting that aside...
If the provider doesn't broadcast the correct details then their STBs won't find the channels. So of course the NIT scan should give you the correct transponder details including frequencies. TV source is not magic; my guess is that it does an NIT scan just like TV Server. NIT is the only standard broadcast source for the provider transponder details.

Maybe I've misunderstood? If so, can you please confirm what you mean by "exact" and explain why you think the NIT wouldn't contain the correct details.

I found an old topic wich covers my needs as well but was never replied:

Well, TV Server has a built in NIT scan function now, so I can only guess that you mean you want to create a tuning detail file. Am I right?
If so I would say to you that creating a tuning detail file for your provider is not necessary. If you can do an NIT scan then you can get correct tuning details every time without needing a tuning detail file.
However if you really want to create the file then you can use the details from the scan output or TsWriter log information as explained above.

Does this answer your question?

PS: For people that use providers which don't broadcast NIT (strange providers!) you can always do an "exhaustive" scan by selecting country "global" and the correct symbol rate for your provider. Then if you want to create a tuning detail file just copy the working transponder details from the global file to a new file (ie. exclude the transponders where channels were not found).
