EPG Data for 'niche' channels ?
OK - so I have my EPG grabber script working well
(http://www.gossamer-threads.com/lists/mythtv/mythtvnz/513747).
Trouble is, the freeview.xml.gz data only covers the 'main'
Freeview|HD channels (1, 2, 3, 4, Maori, U, TV3 Plus 1, C4, Prime,
Parliament, Radio NZ and Basefm).

With so many 'niche' channels starting up (ChoiceTV, TV33, TV9,
CentralTV etc), is there any way of getting their program data in to
Myth? I assume they send EIT data, which would give me at least
short-term program info. I'm on DVB, with no satellite card or aerial.

So: how to set up my backend so the channels without grabber epg data
can still pull some programme info?

I have never tried it, but there is now some MHEG5 EPG support, but
not built in yet. All FreeviewHD channels are supposed to have a full
EPG in MHEG5. Look in the archives for this mailing list to find out
how.

So who here is using this for the DTT channels?

I've had a play with mhegepgsnooppy and what I really need is a way to
provide a mapping file rather than have it probe the MythTV database. The
box i'd usually be running this on has a tuner card, but isn't running
MythTV.

I'm using mhegepgsnooppy. It works great for me with my DVB-T only
freeview system. Seems to get guide data for all the channels I can
receive.
I did have to tweak the channel names that I had to get a good match
all on all channels.

Cheers
Bruce

I use it but then I wrote it. :) An option to use an external channel map file is doable. I'll have a think and let you know if/when I can do it.

Just uploaded version 0.3.3 with option to specify a channel map file.
File format is two fields per row, tab separated, with MHEG channel name
first and xmltv channel ID second. Only briefly tested so quite likely
buggy.

Nice work. Provisional testing worked for me.

I generated the mapping file off a channel scan as follows

cat ../dtt/dtt.conf | cut -f 1,13 -d ":" \
| sed "s/:/ /g" | sed "s/$/.dvb.guide/g" > mheg.list

Then once the card was tuned I could run the EPG grabber and get all the
freeview|HD channels.

I guess mhegepgsnoopy does not work for a hdhomerun?

(there is no dvb device to specify)

You need to specify a file descriptor that behaves like a DVB demux. Don't know if that's possible over a network with an hdhomerun.

I wonder if myth does something similar? Is there something hiding in the /dev tree? Or does myth create a socket? Can it be used (non-blocking)? Just thinking out loud.

I understand the mythtv guys compile in the hdhomerun open source code
with a few tweaks from here and there along the way so that its all in
mythtv. Some people may not be aware of

OK I still have a minor issue. The generated data doesn't include a GMT
offset for the times and is confusing the data load.

For example

<programme channel="1407.dvb.guide" start="20120512203000"
stop="20120512213000">
<title>32 Brinkburn Street</title>
<desc>32 Brinkburn Street has been home to the Ogilvie
family for generations. Loved by most of its occupants,
the house will always be a home at the heart of the
family.</desc>
<episode-num system="dd_progid">TWBS01_01</episode-num>
<rating system="Freeview">
<value>PGR</value>
</rating>
</programme>

VS

<programme channel="1035.dvb.guide" start="20120511163000 +1200"
stop="20120511165500 +1200">
<title lang="eng">ONE News at 4.30</title>
<desc></desc>
<category>tvshow</category>
<category>News/Current Affairs</category>
<!-- Cat:2-0 -->
<!-- Unknown rating:0 -->
</programme>

Ideally this could be based on the timezone of the host, or could be
another command line option.

Sadly the freeview MHEG data isn't based off UMT.

UMT? Never heard of it until you mentioned it. Gives me the shudders
after a quick read on the web. Can't really see why we need it.

Anyway I guess it wouldn't be too hard to include an option to produce
GMT/UTC times with offsets for NZ timezone.

So instead of
20120512203000
you would get
20120512083000 + 1200.

Is that what you need? Actually I suppose the best thing would be
options for local time, plain UTC and UTC with offset to specified
timezone. Make sense?

Hi Steve,

The time issues of Freeview do not end with the absence of Timezone offsets.

All programme start times in the EPG from freeview are expressed as wall clock
time in the system that would be applicabe at the start of the programme.

That means that 2 programmes could have started on the same channel at 2:00am
on Sunday 1st April 2012 when the clocks wentback to end NZDT.

I can only guess that the Freeview / MHEG protocols send a clock change
command whenever it is requied on a MyFreeview DVR device..

I have been working on my own version of a MHEG grabber and I have assummed

a) All times in the EPG are wall-clock time (subsequently confirmed by
careful observation).

b) At end of Daylight Savings, programmes that are due to end at a time
between 2:00 and 3:00 then NZDT is used for the start time and NZST is used
for the end time. Potentially this means that a programme is recorded for 60
mins to long but least nothing is lost.


Regards

Tony Sauri

Hi David. In your MythTV setup for the freeview source what time zone do
you set for the EPG. In my case I default to using AUTO as I import
multiple EPG feeds for different timezones, for example SBS (now sadly off
air).

When I generate listings with epgsnoop the data contains the +1200 offset
based on my local system vs the DVB data.

In the case of DTT I merge DVB and MHEG data so that my DTT and DTH
channels are being provided with identical EPG information. For the DTT
exclusive channels I just pull them from the MHEG file using tv_split and
tv_cat.

Oh the joys of using local timezones. Everything should be UTC.

There's some timezone classes in base.py of epgsnoop that may be of help
for local offset.

Hi Steve. My setting is "none" for the EPG timezone. I only have DVB-T
so it works fine with the MHEG EPG local times. I'll probably do a quick
fix just for you :) that gives you the option to generate UTC +1200 (or
+1300 for DST). Then I'll think about a more general solution. /David

The attention this thread is getting from you script-guys is great! I
look forward to trialing your efforts when they are available and I
have some spare time to tinker. Cheers!

Version 0.3.4 just uploaded. Turned out to be not so simple because (a)
I decided to try and do it right rather than quick and dirty and (b)
surprisingly Python doesn't do time zones very well. Anyway I think it
works. Just add "-z" command line arg. Enjoy.

Just pointing out that accroding to the mythtv DTD the prescription
for date/time formats is:

All dates and times in this DTD follow the same format, loosely based
on ISO 8601. They can be 'YYYYMMDDhhmmss' or some initial
substring, for example if you only know the year and month you can
have 'YYYYMM'. You can also append a timezone to the end; if no
explicit timezone is given, UTC is assumed. Examples:
'200007281733 BST', '200209', '19880523083000 +0300'. (BST == +0100.)


http://xmltv.cvs.sourceforge.net/viewvc/xmltv/xmltv/xmltv.dtd

I haven't followed this thread properly, but the impression I got was
that one of the scripts was not adding a timezone string to the
date/time string, but I was unclear to me whether that script was
creating UTC or localtime.

Doh! I should have RTFM. Would have been easy to add the NZDT or NZST
string to the UTC times or just produce UTC with no timezone string/offset.
FYI the default is/was to produce local times.

Nice try but times are off by a couple of hours.

For example take from DVB-S i get

<programme channel="1035.dvb.guide" start="20120512180000 +1200"
stop="20120512190000 +1200">
<title lang="eng">ONE News At 6pm</title>
<desc>The nation's leading team of journalists brings viewers the
latest news and sport, plus the most comprehensive weather
report.</desc>
<category>tvshow</category>
<category>News/Current Affairs</category>
<!-- Cat:2-0 -->
<!-- Unknown rating:0 -->
</programme>


From MHEG I get

<programme channel="1200.dvb.guide" start="20120511060000 +1200"
stop="20120511070000 +1200">
<title>ONE News At 6pm</title>
<desc>The nation's leading team of journalists brings
viewers the latest news and sport, plus the most
comprehensive weather report.</desc>
<episode-num system="dd_progid">10272257</episode-num>
<subtitles type="teletext" />
</programme>

Well it looks like the DVB-S date/time is wrong to me. The UTC time for
news at 6 pm should be 2012mmdd060000 because we're 12 hours ahead of
UTC. The MHEG UTC time 2012mmdd060000 +1200 equals 6 pm local. Are you
using a time offset of 12 hrs in the myth EPG config or just the auto
setting with no offset?

I have a minor tweak ready to upload which just produces UTC times with
no offset. Maybe that will help.

The following patch fixes it. If the times are UTC you don't need to
specify the offset. If the times are local you need to specify the offset..

*** mhegepgsnoop-0.3.4.py 2012-05-10 18:20:48.000000000 +1200
--- mhegepgsnoop-0.3.4a.py 2012-05-11 12:11:28.000000000 +1200
***************
*** 649,655 ****
hh = int(offset/3600.0) # Divide by float to get correct values for
negatives
mm = (offset - hh*3600)/60
offset = hh * 100 + mm
! start_time = time.strftime("%Y%m%d%H%M00",
time.gmtime(time.mktime(date2)))
start_time = start_time + ' {0:+5}'.format(offset)
else: # If times should be local
start_time = time.strftime("%Y%m%d%H%M00",
time.localtime(time.mktime(date2)))
--- 649,656 ----
hh = int(offset/3600.0) # Divide by float to get correct values for
negatives
mm = (offset - hh*3600)/60
offset = hh * 100 + mm
! #start_time = time.strftime("%Y%m%d%H%M00",
time.gmtime(time.mktime(date2)))
! start_time = time.strftime("%Y%m%d%H%M00",
time.localtime(time.mktime(date2)))
start_time = start_time + ' {0:+5}'.format(offset)
else: # If times should be local
start_time = time.strftime("%Y%m%d%H%M00",
time.localtime(time.mktime(date2)))

No no no, the timezone is +1200 and the date/time is specified in the
that timezone, in other words 1800 hours NZ time (which is 1200 ahead
of UTC).

For example here is the output of date -R on my pffice server just a

On april fools day we had a thread about the timeoffset set to auto vs
none, seems that "auto" doesn't cope with DST time transitions but
"none" does. May or may not be relevant to point out here. It only
affects 12 hours each day of transition however if you are recording
then and expecting some WAF.....
