Freesat channel mapping

[fausto]

I've just got round to updating to v1.3.7 and moving my Nova-S+ card over to my newer P4 machine. I've done a scan and now have to map the channels.
I can't get on with the drop down boxes in the tuning request table. They are not nice to work with. You can't see enough of the list at a time and the scrolling is too fast. I can't keep up with it. Coupled with the fact that the channel list name does not always agree with what should be on that freq/transponder, it's driving me mad :mad:. I don't even have any hair to pull out

Is there a slow but sure way of doing this by editing a text file somewhere maybe?? Suggestions please.

I don't think there is an alternative. I did make a request for a larger pulldown box for mapping but sub went walkabout.

What I often do is to manually edit the scan-?.cache file and get rid of the many odd channels that seem to be alternate languages, data or whatever, then if I feel like it, I sort the cache file on the channel name. Seems to help with the mapping.

Is it even possible to get it to ignore the encrypted ones so the list isn't as annoyingly long?

[martint123]

I must be possible from the scanning as dvbviewer can scan for only unencrypted channels. I see nothing in the scan cache file that would identify them though. Probably down to sub when the channels get scanned.

There isnt a setting in GB-PVR to ignore the encrypted channels during the scan, but you can identify them in the scan results with the "~E:T" part of the tuning request.

Ah, cheers thanks for that - will save lots of time next time I have to do a full mapping.

I modify gbpvr.db3 directly using SQL in a pair of batch files:
The first is:

Code:

:This is _set_tune4.bat and is called by _set4.bat file. It sets the tuning data for a source channel number
:You can use this directly by:
: _set_tune4.bat "SOURCE_CHANNEL_NUMBER" "T:13274 etc. tuning data from scan4.cache file"
:the SOURCE_CHANNEL_NUMBER is the pid (usually)
:Always put parameters in quotes.
:It matches on the channel number for source id 4
Echo UPDATE SOURCE_CHANNEL_MAPPING > _sqlscript.scr
Echo SET enabled="Y",tuning_request=%2 >> _sqlscript.scr
Echo WHERE capture_source_oid="4" and source_channel_number=%1;  >> _sqlscript.scr
SQLITE3 gbpvr.db3 < _sqlscript.scr

This is called by another bat file that lists all the channels I want mapped and the tuning data from scan-4.cache. Here are a few sample lines (the main file has over 250):

Code:

:This is _set4.bat
call _set_tune4.bat "104" "T:12370,V,20000,78~NID:4100~ONID:4100~TSID:11~P:104~V:7458~A:7459~L:eng~PMT:33~E:T~PCR:7458~N:>Unknown1"
call _set_tune4.bat "123" "T:12370,V,20000,78~NID:4100~ONID:4100~TSID:11~P:123~V:7458~A:7459~L:eng~PMT:33~E:T~PCR:7458~N:>Unknown2"
call _set_tune4.bat "137" "T:12370,V,20000,78~NID:4100~ONID:4100~TSID:11~P:137~V:6178~A:6179~L:eng~PMT:33~E:T~PCR:6178~N:>Unknown3"
call _set_tune4.bat "210" "T:12370,V,20000,78~NID:4100~ONID:4100~TSID:11~P:210~V:4898~A:4899~L:eng~PMT:33~E:T~PCR:4898~N:>Unknown4"
call _set_tune4.bat "212" "T:12370,V,20000,78~NID:4100~ONID:4100~TSID:11~P:212~V:5410~A:5411~L:eng~PMT:33~E:T~PCR:5410~N:>Unknown5"

I use UltraEdit to convert the scan.cache file into the second bat file. A macro grabs the PID from the tuning data (it's after "P:") and constructs each line in the second bat file. The whole process takes 5 minutes or so after scanning is finished. Make sure you spend lots of time getting familiar with the structure of GBPR.db3 (I used SQL Browser Lite) , and make lots of backups. You can screw things up badly doing this sort of thing.

You can also create a custom scan-?.cache file using this utility, just including the channels you want:

You need to have a 3rd party viewer (other than GBPVR) working with your card.

Struggling with this myself, as my Compro S350 is now up and running following the installation of a dish this morning. It tunes and everything fine but I seem to missing BBC 2 - it only has Scotland and Wales...so does anyone have a decluttered cache file I can start from, please? Thanks.

I have this in my list

Code:

T:10773,H,22000,56~NID:32~ONID:2~TSID:2045~P:6302~V:5100~A:5101~L:eng~PMT:263~TXT:5103~PCR:5100~N:>BBC 2 England
