#1074323 Reading EPG data from OpenTV (28.2E and 13 E)

Posted by Huevos on 27 June 2019 - 00:55

The only advantage I can see is the data could be added directly to the epg-cache.




#1065841 Unicable LNB in legacy setup

Posted by Huevos on 4 June 2019 - 23:41

UB?

 

Look at the manual for the controller.

 

You either set up some fixed transponders and these are sent all the time. In this mode all the STBs are passive, Just listening. This is nothing to do with Unicable. It is just a feature offered by that LNB.

 

Or you can supply up to 32 tuners. This is Unicable (2). The controller allows you to assign an LNB number in this mode. By default the LNB always responds to every command irrespective of position 1-4, but you can customise it with the controller to only respond to one position number. This allows 4 LNBs over one cable.

I don't think you have understood. You can either:

 

1) configure the LNB as Unicable II

2) or preconfigure it.

 

1) means up to 32 tuners. and I think 4 positions (4 LNBs but the LNBs have to be configured with the controller so they understand positions)

2) means up to 32 transponders from as many LNBs as you like to any number of STBs.

 

The above is related to the Inverto LNB and controller tool.




#1065393 Unicable LNB in legacy setup

Posted by Huevos on 4 June 2019 - 01:43

Example is the Inverto 32 output Unicable II. Using the controller you can map each SCR to a transponder. 32 transponders total. Once save these will be remembered across power cycles. Then you can connect an unlimited number to STBs to it. They don't even need to be Unicable capable.

 

I guess you could attach 32 transmodulators to it but wouldn't it be easier to have a television set with built in DVB-S tuner or DVB-S STBs?




#1059753 Vu+ 4K multistream

Posted by Huevos on 19 May 2019 - 18:03

Maybe Lyngsat was "requested" to remove the PLS values (for the reason in the post above). In that case we should grab it otherwise or we could adjust the grabber script to insert them explicitly.

 

Regarding making bouquets, LCN, etc. I don't like them inside enigma, that would mean a pile of code for every provider, no thanks. So a plugin makes perfectly sense.

After exchanging a couple of emails the values have now returned... so no need to do anything.




#1056985 Vu+ 4K multistream

Posted by Huevos on 15 May 2019 - 20:39

It is very basic. It just reads the LCNs from the SI tables and creates a bouquet file. Enigma does the service scan.

 

Source is available on oe-alliance-plugins. I put it there today so no feedback yet. Will be in the feeds of any image that builds that git.

I made a scanner to make some sort of order out of the MIS chaos.

#1054485 Vu+ 4K multistream

Posted by Huevos on 11 May 2019 - 18:36

No, it is simply said a multiplexing mechanism to put multiple channels in a single datastream. I can only assume it has to do with transponder bandwidth saving.

Main use is to package several terrestrial multiplexes onto one satellite transponder. That way they can be unpacked and broadcast without SI tables being inserted locally. NIT table is for terrestrial. Also LCNs are present on 5W transpondrs so it would be possible to create an automatic bouquet.

#1028785 Blindscan for all models

Posted by Huevos on 10 March 2019 - 11:03

Wouldn't it be useful if somehow the blindscan plug-in code read the frontent capabilities and auto configure the range values from that?
Granted SRs below 1000 are not plenty but in the other hand newer tuners can handle these quite easily if their driver and firmware support them, so why wouldn't blindscan reflect these capabilities too? For instance Availink reports a minimum SR of 0 (although it seems there's a firmware restriction that cuts all SRs below 1000) and now a new test driver for Silabs extends the range to 80000.
And besides blindscan is supposed to find everything, so why argue if that has to be audio and video? In that logic it shouldn't find data transponders either!

Sounds like a good idea, but in practice it is not. For example the sf8008 reports the tuner as 800-46000, but it was the supplier of this STB that requested the blindscan plugin range be extended to 60000.

And now we know that STB will receive as low as 285 (well below its 800 bottom limit). The tuner range is what is considered reliable operation, not what the DX guys can squeeze out of it on some transponders if they are lucky.

 

Also some receivers output SRs outside the range of the blindscan search parameters. Attached image is with the search set to 1 (1000) but it has reached below that to 874. This is what we have to contend with because the executable is closed source, and one of the reasons the Python filters are present. Others don't respect the SR limits at all so 100% rely on the Python filters.

#1010801 Yet another commit that needs reverting

Posted by Huevos on 1 February 2019 - 11:34

I think the reasoning was that hardware depends on drivers.

Yes but every enigma receiver can do this without any changes to the drivers just by using astra-sm.

 

Also, for some reason this commit links T2MI to multistream capability. That is wrong. This commit should not need to touch the multistream code.

 

And the user still needs to know pid details just to be able to scan. What other scan ever requires the user to enter pid details? And even if those pid details are known by the user they are not saved in lamedb so how is it supposed to work across reboots?




#983041 satellites.xml is wrong !

Posted by Huevos on 16 December 2018 - 23:17

 

It looks like there is something wrong with entries for 21.6E satelite.

Some of the SR's are too short.

 

The short SR's are OK, It are low symbol rates (radio stations)
symbol_rate="255000" = SR 255
symbol_rate="376000" = SR 376
symbol_rate="512000" = SR 512

 

Yes they are correct. The SR is low because there is no point wasting bandwidth having a higher SR for such a small amount of data. But such a low SR is beyond the scope of most satellites tuners as these are designed for TV transport streams so not able to filter such a narrow bandwidth.




#947714 Unicable / simultaneous recordings

Posted by Huevos on 14 October 2018 - 16:35

Tell me where/how and I can add and test.




#937815 Unicable / simultaneous recordings

Posted by Huevos on 23 September 2018 - 16:13

Just to avoid confusion...

<  1041.106> [eDVBResourceManager] allocate channel.. 0802:0002
<  1041.106> [eDVBResourceManager] available channel.. 080e:0002

0x0802 is the TSID to be recorded.

0x080e is the TSID of the currently playing service.




#925883 Enigma2 and BBC/ITV at 27.5W Intelsat - a big challenge

Posted by Huevos on 28 August 2018 - 17:21

Robertooo, I have these but need to check this evening if they are still working:

I

 

How can that be valid?

c:0917d90101

Cached data. Field tag [lower case] c: followed by two decimal digits and four hexadecimal digits. For example c:010282 is composed of 01 decimal cache id, 0282 hexadecimal value to cache.

 

As far as I see in the DVB standard the PID number is a 16 bit integer, i.e. in the range of 0x0000-0xFFFF.




#922835 satellites.xml is wrong !

Posted by Huevos on 22 August 2018 - 14:44

I am against offering code to individual users that will increase load on Lyngsat. My script does the download over several hours to try to avoid causing any load issues on that website. If for some reason a captcha is added to that site it will be a nightmare for everyone. People that want an individual customised xml can easily download it from satellite-xml.org. And anyway the file offered by OpenPLi and OE-Alliance is a pretty good file for the majority of uses.

 

I swap the position data before putting it in the database. That way the positions in the database will always be the same.

 

The basics of my code to pull the positions is as follows. Note there are no collisions in this list but the complete code has a workaround just in case a new satellite causes an unexpected one (unlikely due to allocations, e.g. 0.8ºW and 1.0ºW share the same page so will show as one satellite).

 

List of fixed sats:

$fixed_slots = array(
						'57.0E', '56.0E', '54.9E', '53.0E', '49.0E', '45.0E', '42.0E', '39.0E', '36.0E',  
						'31.5E', '30.5E', '28.2E', '26.0E', '25.5E', '23.5E', '21.6E', '20.0E', '19.2E', 
						'17.0E', '16.0E', '13.0E', '10.0E', '9.0E', '7.0E', '4.8E', '3.0E', '0.8W', '4.0W', 
						'5.0W', '7.0W', '8.0W', '11.0W', '12.5W', '15.0W', '18.0W', '20.0W', '22.0W', 
						'24.5W', '27.5W', '30.0W', '31.5W', '34.5W', '37.5W', '40.5W', '43.1W', '45.0W', 
						'50.0W', '53.0W', '55.5W', '58.0W'
					);

Convert the slots to positions:

function slot_2_orb_pos($slot)
{
	$orb_pos = intval(substr($slot, 0, strlen($slot)-1)*10);
	if(substr($slot, -1) === 'W')
	{
		$orb_pos *= -1;
	}
	return $orb_pos;
}

And then to check if the current position is in the fixed slots and migrate if necessary:

function check_against_fixed_orbitals($orb_pos, $orbitals)
{
	$tolerance = 3;
	foreach($orbitals as $pos)
	{
		if($orb_pos <= ($pos+$tolerance) and $orb_pos >= ($pos-$tolerance))
		{
			$orb_pos = $pos;
			break;
		}
	}
	return $orb_pos;
}

If you want the whole script I'm happy to send it but would like it kept private.
