UK Freeview HD channel EPG data corrupted

LS80 · Sep 9th 2015

I have a problem with nonsense epg data for UK Freeview HD channels. I don't know if this is a character encoding issue or something more sinister. All the SD channels appear to be fine.

Here is a problem part of my epg.data with the BBC ONE HD data
epg.data

The channels.conf line for BBC ONE HD is
BBC ONE HD:682000000:C23D0G32I0M256P0Q16434S1T8X1:T:0:6601=27:6602=eng@17,6606=eng@17:0;6605=eng:0:17540:9018:16515:0

w_scan would not find the HD channels so I had to create this line myself from a working tvheadend config. Is there anything obviously wrong with this line or does it look like a VDR epg bug?

I just noticed that the first two bytes of the T field are a CSI (Command Sequence Introducer) encoded in UTF-8 (0xc2 0x9b).

Hi,

I am a user of freesat and rely on vdr-plugin-eepg for proper EPG. I think eepg plugin is the way to go for you too as freeview EPG should be also supported by now.

Reason: http://projects.vdr-developer.org/issues/692

Thanks, I've been doing some research and apparently the UK Freeview HD channels use something called Huffman encoding for the EPG data which isn't supported by VDR core but is supported by tvheadend
https://github.com/tvheadend/t…blob/master/src/huffman.c

I've tried the eepg plugin but that didn't make any difference. The issue you linked to implies that support was added for Freeview so either something changed with the broadcasts or I am doing something wrong. Did you have to configure anything other than installing the plugin? I am compiling everything from source on Arch Linux and now have
/usr/local/lib/vdr/libvdr-eepg.so.2.2.0 which I presume should be loaded and used automatically.

This thread looks useful

All I can say is:

1) eepg works for me with freesat and freesat is also using the Huffman encoding (which is not an open DVB standard and therefore not supported by VDR core)
2) at some point it seems that eepg has worked with freeview (according to my link)
3) freeview epg can't be changed by provider without firmware updates to all STBs so I think it's unlikely they changed the format
4) Ask Tony Houghton as his name is all over the place when it comes to VDR + freeview / freesat

Cheers,

I agree with hepi. I have been a happy eepg user for more than a year, watching (among others) the BBC HD channels.

I am using Freeview (DVB-T2) not Freesat.

LS80: You can also ask user gandalf247 aka lanks as he has moved to the UK and is using freeview now: Umrüstung DVB-S/S2 -> UK ATV/DTV [ gelöst ]

I PM'd him but he hasn't switched to Freeview yet.

FWIW I've started using vanilla VDR again and have access to FreeviewHD so I've updated the patch to VDR 2.2.0, available here: http://rst38.org.uk/vdr/freesat_vdr2.2.0.diff It needs a bit of a tidy up but it does work.

Thanks, your patch has fixed my problem.

Do you have a working patch for 2.3.1?

d0m · Sep 27th 2015

I've not upgraded yet, however I've checked and the patch applies and compiles. Does it not work?
