Description Juhani Simola 2012-11-17 20:07:08 UTC

When scanning for DVB-C channels in Helsinki region using the scan data Kaffeine automatically downloads, at least the channels SubTV, Nelonen and JIM are missing.

The three channels were scanned correctly after I added the following line to [dvb-c/fi-HTV] section of .kde/share/apps/kaffeine/scanfile.dvb:
C 282000000 6900000 NONE QAM128


Reproducible: Always

Steps to Reproduce:
1. Download the initial tuning data using Television / Configure Television / Update scan data over internet
2. Start channel scan
3. Try to find SubTV
Actual Results:  
Scan finds many channels but not SubTV, Nelonen or JIM

Expected Results:  
Scan finds many channels including SubTV, Nelonen or JIM

The three channels were scanned correctly after I added the following line to [dvb-c/fi-HTV] section of .kde/share/apps/kaffeine/scanfile.dvb:
C 282000000 6900000 NONE QAM128

Use this http://www.linuxtv.org/wiki/index.php/Dvbv5-scan to scan your channels and then send the results to linux-media@vger.kernel.org

Let me know when this is done and Kaffeine source will be updated.

Tried with dvbv5-scan from ubuntu package v4l-utils and initial tune data from dtv-scan-tables, got this:

ojs@eris:/tmp/dtv-scan-tables$ dvbv5-scan dvb-c/fi-HTV 
INFO     Scanning frequency #1 274000000

I tried to build dvbv5-scan myself but got this:

and no generated Makefile

Looks like someone has added the missing and dozens of others to the scan file that is downloaded when you make Kaffeine download scan data from Internet, though.

Comment 3 Juhani Simola 2015-08-27 19:09:49 UTC

The current scan file still gets at least one line wrong: 
C 290000000 6900000 NONE QAM256
finds the bundle that contains Yle HD channels. The file comes with QAM128.

Comment 4 Juhani Simola 2015-11-08 22:32:23 UTC

I managed to get channel scanning to work with Arch. Here are the results from wscan -fc -c FI -x. I tested that this initial scan list finds all channels in Welho network (the identifier "fi-htv" is obsolete as well)

Comment 5 lasse.k.lindqvist 2015-11-09 21:13:59 UTC

The long term solution is to let the good people at linuxtv know about the frequencies.

Comment 6 Juhani Simola 2015-11-10 20:52:33 UTC

I did before posting the scan results above. No response so far, and the downloaded scanfile is still wrong.

Comment 7 Mauro Carvalho Chehab 2016-06-06 00:57:14 UTC

There is a commit for dtv-scan-tables tree updating the dvb-c/fi-HTV file.

commit 9d6094a7c41e1ad11b90e719be12592222d57f90
Author: Ville Skyttä <ville.skytta@iki.fi>
Date:   Wed Jan 6 15:47:35 2016 +0200

    dvb-c/fi-HTV: Update from http://dvb.welho.fi/hel5-sidump1.xml

On a quick look, it seems that it has already the channels you scanned. Anyway, if something is still missed, please send the dtv-scan-tables update to linux-media@vger.kernel.org.
