[ViX_Misc] EPG Refresh, iEPG and VPS

[goRt]

If I have EPG refresh configured to use iEPG-1 to provide EPG data
VPS plugin no longer starts and ends programmes - there are 2 scenarios, the timer never starts and eventually gets cancelled after 3+ hours; the timer starts and immediately ends.
If I switch to safe mode, then I can see the start and end recording signals displayed in the recording (at playback time)

If I purge the EPG data and use EPG refresh on a per channel basis, then VPS plugin accurately starts and ends recordings correctly.

Is the data provided by iEPG-1 somehow wrong, does EPG refresh process it incorrectly or is there some other error?

Thanks

OK, now I've got time on my hands again:
1. If I clear the epg and then use crossepg to populate the sky epg then the programme EITs that work with VPS ie the EIT matches that of the now/next EIT used for programme signalling but,
2. If I clear the epg and then tune to IEPG-1 to populate the sky epg then different EITs are downloaded, EIT does NOT match the now/next EIT and recordings fail

This can be examined by downloading the timers.xml and the EITs are massively different for given programmes - EIT for pointless today (after channel swap for covid) from IEPG is 49684; whereas from crossepg it is 18580

So EPG refresh is not fit for this purpose

EPG refresh is just a channel zapper. The code to do the zapping is built into Enigma2, but people obstruct request to add the functionality to add timers using Enigma2 and suggests we use EPG refresh.

There are two types of EIT EPG. Now/next is one type and changes while you are on the channel. Can you explain more by what you mane by EIT?

Thanks for the quick response.
Yes EPG refresh is just a zapper, I get the same result by tuning to IEPG-1

The correct EIT is produced by crossepg - I'm unsure where this comes from (you know that black box that appears at the top of the screen)

If you look at the EIT number in timers.xml that comes from IEPG v crossepg (by adding a timer from one source, clearing the epg.dat) they are different numbers for the same programme, VPS uses the now/next EIT for programme signalling (it allocates the channel 10 mins before scheduled recording start by default) and waits for the EIT data to match that within the entry timer.xml; when that doesn't match you get a 0:00 recording or very short recording before VPS notices the EIT from now/next now no longer matches the now/next.

I come from a toppy background where EIT was used extensively

VPS, unfortunately, very unfortunately, does not work any longer under 5.4, even 5.4.004 as well as in OBH 4.4.004, its derivative.
This is an already discussed problem. I find VPS, for the channels where it work, one of the most useful plugins.
That's why I'm not using these two images and went back to ViX 5.3 and OBH 4.3.

Sorry, the changes made to VIX in 5.4.xxx have made VPS display and selection awkward (but it functions in webif and for autotimers), BUT the issue I describe existed prior to 5.4.xxx.
My original post is 10 months old predating 5.4.xxx, if you follow the steps to replicate on 5.3.xxx then the issue as reported (EIT mismatch between iepg-1 and the actual channels is there)

Thanks

Now I don't have ViX 5.3 installed any more but it surely under its cousin OBH 4.3 whilst it surely doesn't under ViX 5.4 and OBH 4.4, that's why I got back to OBH 4.3, at the moment, where I use it everyday.
About OWIF, it seems to work, in the sense you are there able to set it or edit an existing one. But then it doesn't really work.
Maybe it happens only if you just access the timer by the GUI (I can't remember now). But even if it were so, it'd be unbearable the same.

I'm referring to the eit on the ipeg channel v the actual channel transmission NOT the issue with VPS.

A crazy idea.

 

[goRt]

Just to add,
the EIT on sat (via crossepg) and terrestrial match for a given programme (as they should),
so either iepg-1 is transmitting the incorrect data *or* the inbuilt epg harvester is incorrectly populating the EIT field.

 

[Huevos]

There is no EIT on 28 east.

There is now/next, proprietary 7 day Freesat and proprietary 7 day Sky.

If you zap to IEPG directly, or use epgrefresh, or use CrossEPG the data source is always the same, i.e. 11778 V.

 

[ronand]

Crossepg doesn't download the EIT data (it downloads EPG data). EIT data is broadcast on the actual channel you are watching/recording and will be read by the EIT reader if enabled. Some channels just do NOW/NEXT while it is increasingly common to get up to 7 days data using this method. The data can (and usually will) be different from the EPG. EIT data is likely to be updated on the fly and will be more accurate at broadcast time. On satellite there are several sources of epg data (freesat/sky/EIT) so care must be taken not to mix them up. A proprietary box will be preset so no confusion arises. Comparing satellite and freeview EPGs is not valid as they have different providers (and different epg providers)

I'll say again... there is no EIT on 28 east.

 

[ronand]

Where does the Now/next data come from then? That is EIT data AFAIK

1. So what's the field in the timers labelled eit?:

<timer begin="1611478800" end="1611482520" serviceref="1:0:19:1B1D:802:2:11A0000:0:0:0:" repeated="0" rename_repeat="1" name="The Andrew Marr Show" description="Andrew Marr is joined by Nicola Sturgeon MSP, Matt Hancock MP, Lisa Nandy MP and Yuli Edelstein.

[28.2e and terrestrial]

2. And what does the VPS plugin interrogate then?

3. Why doesn't the eit field populated from iepg-1 match that from crossepg - if, as you assert, they are from the same source then the inbuilt harvester must be incorrectly populating the field:

Crossepg:

<timer begin="1610996400" end="1611000120" serviceref="1:0:19:52D0:814:2:11A0000:0:0:0:" repeated="0" rename_repeat="1" name="Channel 4 News" description="Channel 4&apos;s flagship news programme.

</timer>

iepg-1:

Not sure what you're trying to prove, you've shown 3 different programmes from 3 different sources?

 

[Huevos]

EIT Schedule is not present on 28 east so anything that is not now/next must come from a proprietary EPG, i.e Sky, Frresat or online download.

 

[ronand]

The only EIT data on 28e is NOW & NEXT data (but it is EIT data). Freeview (terrestrial) has full 7 day EIT data.

 

[goRt]

Not sure what you're trying to prove, you've shown 3 different programmes from 3 different sources?

and 3 different numbered questions - so we can see the answers to each question.

The first sample shows the identical eit data on DVB-S and DVB-T and asks where that comes from on DVB-S

The 2nd 2 samples show DVB-T sampled from iepg-1 and crossepg and that the eit field is different (and incorrect) on iepg-1
