#9480 assigned Patch - Bug Fix

National characters in polish EPG (Cyfra+ and Polsat) won't work :(

Reported by: marcin.jachurski@… Owned by: dekarl
Priority: minor Milestone: 0.27.1
Component: MythTV - EIT Version: 0.24
Severity: medium Keywords:
Cc: Ticket locked: no


Polish (Hotbird) DVB-S operators give EPG encoded in the ISO-8859-2 (Polsat)
and in ISO-6937 (Cyfra+). Unfortunately does not give information
about encoding. Polsat is not suitable byte identifying coding.
Cyfra+ gives the wrong marker.On the programs broadcast together
we get different coding, both wrong.

MythTV allows to specify the encoding, but only for the transponder,
which is transmitted program (in eithelper.cpp). In this case it is
necessary to specify the encoding to the network or the transponder
from which the EPG has been received.

I wrote an patch, which adds forcing iso-8859-2 and iso-6937, depending
on the source transport and/or network id, not on TSID() and
OriginalNetworkID() from existing DVBEventInformationTable.

There is someone who had similar problems and have any comments?
Maybe I am wrong to do?

This new encodings:
ISO-8859-2 for source network id 113
ISO-6937 for source network id 318

Also other channels from Hotbird:

TVP Kultura
TV Biznes
Mango 24
Rebel TV
Eska TV
VIVA Polska.

But it was at Mon Dec 29 11:44:02 UTC 2008 and no one fix the problem until 0.24 version. If you need screenshots or database backup or any log. Please let me know. Polish people are frustrated at polish forums. And said that "We don't have full support for polish language :( "

Please fix it in the future version of MYTH TV. I am happy with that software so that's why i am asking you.

Good solution will be create field in channel table in database with EPG encoding from the air. After that all problems with any encodings in EPG will be solved.

Im attaching a patch originally wrote by Wagabunda, this is old thread and description:
I only fixed this to patch cleanly against 0.24-fixes.
This is not best possible solution because it *might* break on other satellites, its using some probably reserved bits. However works great for me.

It is great to have addressed PL chars on polish sat EIT. This patch works great for me with passive scan (2 weeks of tests). However with active scan I have quite frequent random errors with PL chars in prog titles or desc. I'm almost sure it is correlated with active scan as last 2 weeks I was on passive mode without any issues. Last evening I turned on active scan and now I have a lot of progs. with bad pl chars. I'm on 0.24-fixes 20110415. I'll be more that happy to help debug problem.
