Re: xmltv-users Digest, Vol 64, Issue 5

Maybe I don't understand how this forum works.
I posted my question three weeks ago.
I see my question posted, but no one has answered it.
Am I doing something wrong?

Thanks Nick, I'll start taking a look at the debug output periodically.

Thanks again. I'll try and properly learn the correct fixup style and 
post in diff format in the future.

I was hoping for some sort of web form to fill in, but I suppose that 
has additional problems such as guarding against spammers, usernames and 
passwords, and so on...!

I keep getting the following messages when I run tv_grab_na_dd.

I ran a query a few nights ago on my then-current 14-days of listings
for my Virgin TV video source in MythTV to count flagged repeats and
was quite surprised by the findings. This query was clearly automated
and I haven't checked the listings manually to look for mis-flagged
repeats (I'll add premiere/repeat counts to the grabber's debug
output).

The query was:

SELECT
  `channel`.`name` as "Channel",
  count(*) as "Programmes",
  count(nullif(`program`.`previouslyshown`,1)) as "Unknown",
  count(nullif(`program`.`previouslyshown`,0)) as "Repeats"
FROM
  `program`,`channel`
WHERE
  `program`.`chanid` = `channel`.`chanid` AND `channel`.`sourceid` = '2'
GROUP BY
  `program`.`chanid`
ORDER BY
  `program`.`chanid`;


The following channels (ignoring any timeshifted versions) provided no
repeat flagging at all:

Watch
GOLD
Dave
Alibi
Comedy Central
Syfy
5*
5USA
Universal
DMAX
Quest
Blighty
Eden
Discovery
Animal Planet
Disc History

It's a bug in MythTV if it's using provided data incorrectly (or
worse, creating erroneous information when none is given). As Karl
mentioned, MythTV's listings infrastructure is heavily skewed toward
the TMS/Schedules Direct services and the very rich data they provide.
Other XMLTV sources - uk_rt included - do not provide such rich data.

Cheers,
Nick

That's interesting.  I guess it may have something to do with these
channels not being the original broadcaster / Programme Maker?

I don't think it's a but.  What MythTV (or more exactly the display
Theme which I use on my Frontend)  is doing is always displaying the
value in the 'airdate' field - and tv_grab_uk_rt is being a bit
inconsistent in what it puts in there.

(I haven't noticed if I would see the 'originalairdate' displayed
anywhere by MythTV, because don't think it is ever set by
tv_grab_uk_rt.)

Personally I think it would make most sense that, if a 'programme
origin date' is available (as it is for movies) then it would be put
in the 'originalairdate' field in MythTV, and the airdate is left as
the 'airing' date.  (So I could see that this is a 1976 movie,
broadcast in 2004)

I don't know whether the Radio Times data allows tv_grab_uk_rt to make
this distinction, or whether that would break anyone else's uses of
the data?

Regards,

D

Checking
http://miffteevee.co.uk/documentation/development/group__db__schema.html
states that " 'airdate' is a string representing the year of release
for movies and may have no meaning for other types of shows". This
agrees with how uk_rt presents <date> information in the listings.

I've checked today's uk_rt XML file to see how dates are being
included in the grabber data and whether there is any inconsistency.
The only programmes where the <date> element is present are theatrical
and TV films, one or two documentary films and multi-part TV dramas
presented as films, such as Columbo and Perry Mason. For such
programmes the date given is the release/copyright date - separate to
MythTV's concept of originalairdate - and they all seem to be fine.

Can you provide any examples of which programmes you are seeing
inconsistencies with?

I have a few years of archived data so I can look back for specific
programmes if you can provide them. Again, make sure that the data is
coming from the uk_rt grabber and not MythTV's import handling of the
data or its display in an OSD theme.

originalairdate is not available from the uk_rt grabber.

"If it were up to me" I would keep the release/copyright date separate
from airdate (year of this showing of the programme on TV) and
originalairdate (year of premiere showing of programme on TV in
locale), as the release date of a film or documentary is a different
concept to either of these other values.

One may have the scenario where a brand new documentary is released
and premiered on TV in the same year such that all three values
(release date, airdate and originalairdate) are the same, but these
values would be different often enough to warrant storing and handling
them separately.

To the best of my knowledge, all of the data that the Radio Times feed
provides is used by the uk_rt grabber in the way intended by the XMLTV
DTD.

Nick

Nick,

I should have read that document before I started this thread!

I don't think there is anything wrong with the xml data since there's
no way of knowing whether the 'airdate' has meaning or not.

I may look and see if there's a way of suppressing 'airdate' in the
MythTV theme for everything except movies; but I may not, now I
understand why it's there.

I agree.

D
