Where do I find bbc_pmt_v6.py? I'd like to give it a try as I seem to have a mixed up lamedb probably full of redundant parameters. Should lamedb be different for OpenATV and OpenPli?

The script works correctly only in Py2.

Hi EnoSat.

Ive done a bit more testing, and i do see a signal on 11044V, and can see its a QPSK at 44110 SR and 9/10.
It is too weak to get a signal lock for channel search. There is a signal right below it with out any guardband, maybe thats a signal from the Medcentral beam.
I will do some more testing, and report back, if im able to get any more useful data.

Cheers

This morning the signal locks and I can now confirm the channels are there. But it's having a hard time keeping the signal lock.

Cheers

Thanks for the info, I found it and tried this morning on my Zgemma h9s with OpenPli but didn't get far.

 

 I would really like to find a comprehensive explanation of how lamedb is derived as I have two boxes that both decode 27.5w but have entries  that differ.

Here are 2 pictures of the V and H spectrum around 11043. Its clear to see there is another signal colliding with the Freeview TP, and that its not a skew problem. (yes my screen needs a cleaning)

[EnoSat]

The problem is not V/H, but 11043V North Sea vs. 11014V EuroSpot 2 (MedCentral)

Is f:4 equal to f:1005?

Is f:400 equal to f:1400?

[EnoSat]

1005 = f:1 + f:4 + f:1000
1400 = f:400 + f:1000

"f" means "flag".

 

I documented this as best I could a few years ago.

Thanks Huevos,

lamedb cached PID data
----------------------

c:00xxxx = video pid
c:01xxxx = audio pid (MPEG)
c:02xxxx = Teletext pid
c:03xxxx = PCR pid
c:04xxxx = audio pid (AC3)

c:100007 + c:11xxxx = audio pid (AC3+) ???
c:100004 + c:11xxxx = audio pid (HE-AAC) ???

c:10xxxx = cached volume level ???

c:11xxxx = audio pid (AAC)

----------------------------------------------------------------------------------------------

lamedb service flags
--------------------

dxNoSDT=1,    // don't fetch SDT
dxDontshow=2, // don't show service in all services list
dxNoDVB=4,  // dont use PMT for this service ( use cached pids )
dxHoldName=8, // don't change service name if label differs in the SDT
dxNewFound=64, // show in last scanned bouquet ( until next restart )
dxIsDedicated3D=128, // 3D channel
dxIsParentalProtected=256, // service with parental protection
dxHideVBI=512, // Hide VBI line (dotted line along top of screen on some channels )
dxIsScrambledPMT=1024, // identical to dxNoDVB when used in pmt.cpp and in servicedvbstream.cpp used to record cached pids
dxCenterDVBSubs=2048, // Centre DVB subtitles
dxNoEIT=4096, // disable EIT event parsing when using EPG_IMPORT

It is a bit different from what EnoSat is saying. 

Your "numbers" look binary. But f:400 and f:1000 do not seem binary but I am not a coder, so I may not understand it all.

Because Huevos wrote it for you in DEC, but you have to enter it in the file in HEX

[EnoSat]

as I wrote in post 1886, a simple description is also here on the forum, but no one is allowed to use the Search

The flags are in dec in the C++ code.

Just not in lamedb.

Do you get subtitles on ITV HD with these parameters in lamedb?

Yes, since you entered a different PID than Robinson

 I think I got it working but what should be happening to the data?

Is  "/tmp/camd.socket" the right place for OpenPLi 9.0?

 

The data is received if I run my own server.

Thanks. I had an error in my c:09 entry. 

[v12nut]

anyone else lost 27.5w? I have no signal in northern Spain

[bloke76]

same here. I first thought the signal has gone due to heavy storms over here and the dish has been moved. 

but unable to get it back, seems that the transponder has been switched off. 

we need to move to telstar now, well. if you are in the region for the footprint.
