EPG Automatic Recording adjust

Added by markus frei almost 9 years ago

If I select to record a film via my DVB-C card using TVHeadend and the EPG (provided by my cable provider), and if the provider decides to change the time the film is broadcast, does the recording time automatically get adjusted provided the EPG data gets corrected by the provider to accommodate the new time of broadcast? Or are there any settings within TVHeadend that I need to change so this is done?

At the moment it seems that often the recording starts at the wrong time, with films starting much later than they should have and then being cut-off before they end, and I'm not sure about who is to blame, the Cable company who provides the EPG and doesn't correct it's timings, or TVHeadend. So before I go after the cable company and blame them for a bad service I'd like to make sure TVHeadend works properly... It is difficult to check the EPG data as usually when I realize it the problem has already happened and it is too late.

Thanks for your help.

If you're using OTA EPG then yes, more than likely it will adjust (certainly I see "time updated" messages) if tvh sees the change in time when it scans and matches events. However, a published EPG, such as an XMLTV scraper, and no - simply because it would never know about the change.

I believe recent (last few weeks) versions of tvheadend have EITpf enabled (it's "Use EPG running state" in the recording profile options, I think). If you're using an EPG that updates realtime, then, so tvheadend will keep adjusting it even if it's not looking for new events. That does assume your broadcaster supports it as well, though.

I think....!

Thanks for the comment.

Where can I check if "EITpf" is enabled? I can't see it using the Web Interface under "Digital Video Recorder Profiles". Do you know if EPG and DVR updates are logged somewhere, and if yes, which those log files are so I could have a look at them?

Cheers,

OTA EPG EITpf can be used to do "Accurate Recording"
Refer to my previous answer here https://tvheadend.org/boards/5/topics/17698?r=17725#message-17725
I am quite happy with the results I get.
If tvheadend is implementing this, as Prof Yaffle indicates, that would be very good.

It's already in git master & it works extremely well here in the UK :)

Thanks for the info, but what is "git master"? I installed TVHeadend on a MakuluLinux system using the following link:

https://tvheadend.org/projects/tvheadend/wiki/AptRepository

and the Official releases stable branch. Would I need to install one of the other releases (testing/unstable - which one)?

git master is the development code. So you're into installing a nightly or building it yourself.

Nightlies are in "master main", I believe - expect daily updates, though, and perhaps some breakage (although it's pretty reliable for many of us - it depends on what features you use, of course).

Thanks for the info. I'll try the "Master main" version. It will probably take some time to find out whether recording now works "on time".
