DESCRIPTION
Output TV listings in XMLTV format for many channels available in the United Kingdom and
Republic of Ireland. Source data comes from machine-readable files made available from
the Radio Times website.
USAGE
First run tv_grab_uk_rt --configure to choose which channels you want to receive listings
for. Then run tv_grab_uk_rt (with optional arguments) to get around 14 days of listings
for your configured channels.
OPTIONS
--help Print a help message and exit.
--version Show the versions of the XMLTV libraries, the grabber and of key modules used
for processing listings.
--capabilities Show which capabilities the grabber supports. For more information, see
<http://wiki.xmltv.org/index.php/XmltvCapabilities>
--description Show a brief description of the grabber.
--config-file FILE Specify the name of the configuration file to use. If not specified, a
default of ~/.xmltv/tv_grab_uk_rt.conf is used. This is also the default file written by
--configure and read when grabbing.
--output FILE When grabbing, write output to FILE rather than to standard output.
--days N When grabbing, grab N days of data instead of all available. Supported values
are 1-15.
--offset N Start grabbing at today + N days. Supported values are 0-14.
Note that due to the format of the source data, tv_grab_uk_rt always downloads data for
all available days and then filters for days specified with --days and --offset.
Specifying --days and/or --offset in order to speed up downloads or reduce data transfer
will therefore have no effect.
--quiet Suppress all progress messages normally written to standard error.
--debug Provide detailed progress messages to standard error. Due to the volume of debug
information produced, it is not advised to use this option during normal grabber use.
--gui OPTION Use this option to enable a graphical interface to be used. OPTION may be
'Tk', or left blank for the best available choice. Additional allowed values of OPTION
are 'Term' for normal terminal output (default) and 'TermNoProgressBar' to disable the use
of Term::ProgressBar.
--configure Prompt for which channels/lineup to download listings for, where to store the
cache directory for retrieved listings, what character encoding to use for output, and
whether to enable programme title and bad character fixups.
--list-channels Outputs an XML document containing all channels available to the grabber.
--list-lineups Outputs an XML document containing all channel lineups available to the
grabber.
--get-lineup Outputs an XML document containing the configured channel lineup.
SOURCE DATA TERMS OF USE
All data is the copyright of the Radio Times and the use of this data is restricted to
personal use only. Commercial use of this data is forbidden. <http://www.radiotimes.com/>
In accessing this XML feed, you agree that you will only access its contents for your own
personal and non-commercial use and not for any commercial or other purposes, including
advertising or selling any goods or services, including any third-party software
applications available to the general public.
CHANNEL LINEUPS
A channel lineup is a list of TV and radio channels that are available in a particular
location on a particular TV platform (e.g. Freeview).
Whilst configurations containing individual "channel=..." entries are still supported, the
grabber allows a user to select their location and TV platform at configuration time and
have their channel lineup generated dynamically at runtime. This means that if a new
channel launches or a channel ceases broadcasting, an update to the relevant lineup
(stored on the XMLTV server) will result in listings containing such channel changes
without any reconfiguration by the user.
CHARACTER ENCODING
During configuration, the software asks the user to choose the character encoding to be
used for output. Currently supported encodings are UTF-8 and ISO-8859-1.
TITLE PROCESSING
Over time, listings may contain inconsistent programme details, such as the programme
title combined with episode details for some showings of a programme, but separate for
others; or the episode title being given as the programme title, and the programme title
given as the episode title. Some programme titles may also change slightly over time, or
across channels.
Enabling title processing during configuration enables this software to process programme
titles against a list of flagged titles. The software will correct such programme titles,
which in turn should result in better performance of PVR software which rely on consistent
programme data. Please be aware that enabling title processing will result in the grabber
taking slightly longer to complete its operation due to the extra processing overhead.
N.B. Please note that title updates can clearly alter programme titles near to
transmission time, and it is therefore quite possible for PVR schedules to fail if they
have been configured using an old title. Whilst care is taken to ensure title updates are
made as far ahead of transmission as possible, be aware that last minute updates can be
made.
MIS-ENCODED UTF-8 SOURCE DATA
Prior to the transition of the XMLTV service to metabroadcast.com in December 2011, there
was an ongoing issue with source data containing mis-encoded UTF-8 characters. Since the
transition, the source data should be UTF-8 safe and automatic processing of the data may
not be required. A configuration option is provided to permit detection and correction of
such character encoding errors and users are recommended to enable this option during
configuration.
PERFORMANCE
Improvements to date and time handling in the grabber have increased performance 6-7X.
Grabbing 14 days of listings with utf-8 and title fixups enabled should take about 2
seconds per configured channel on a typical machine.
ERROR HANDLING
tv_grab_uk_rt will only terminate early if it is impossible to continue with grabbing
data. This can be due to a lack of channel configuration data, a bad/missing configuration
file, or filesystem permission problems. Running the grabber in non-quiet mode should
report why the grabber failed.
Non-fatal errors are reported during a grabber run, and can result in listings for a
channel being skipped either in part, or entirely. Progress messages will state why data
is missing when it is possible to do so. A non-zero exit status will normally be given
when the grabber has encountered problems during listings retrieval.
ENVIRONMENT VARIABLES
The environment variable HOME can be set to change where the configuration file is stored.
All configuration is stored in $HOME/.xmltv/ by default. On Windows it might be necessary
to set HOME to a pathname containing no spaces.
The environment variable XMLTV_SUPPLEMENT can be set to change where the supplemental
XMLTV files are retrieved from. By default, the file is retrieved from the XMLTV
supplement server. See XMLTV::Supplement for more information.
If you want the grabber to use customised local copies of the supplemental files, you
should set XMLTV_SUPPLEMENT to the path of the directory containing a tv_grab_uk_rt/
directory containing the supplement files. For example, if your local supplement files are
stored in /usr/local/share/xmltv/tv_grab_uk_rt/ you should `export
XMLTV_SUPPLEMENT="/usr/local/share/xmltv/"` before running the grabber.
RADIO LISTINGS
Ironically, the Radio Times feed does not offer listings for radio. They have been asked
about the possibility of adding radio listings, but stated that this would require
significant development effort. It has not been ruled out entirely, but is unlikely to be
added soon.
Users who would like to obtain BBC radio listings in XMLTV format are advised to
investigate a new grabber that obtains listings from the BBC Backstage service. See
<http://wiki.xmltv.org/index.php/BBC_Backstage> for more information.

BUGS
If you encounter a reproducible bug, please report it on the XMLTV bug tracker at
<http://sourceforge.net/tracker/?group_id=39046&atid=424135>, making sure you assign the
bug to the tv_grab_uk_rt category. Please check that the bug has not already been
reported.
The source data on the Radio Times website is generated daily before 0600. Occasionally
the source data may not get recreated, leaving the source files for some (or all) channels
empty. Users are encouraged to wait at least 1 day before reporting an issue with missing
listings, as they frequently reappear in the next update or later the same day. If
listings continue to be missing from the Radio Times website, please report the fact on
the XMLTV users mailing list.
There have been several occasions in the past when the Radio Times channel index has been
missing from the Radio Times website. This file is essential to being able to run the
grabber, as it contains the list of channels having available listings data. If this file
is missing or empty, and there is no locally-cached copy of the file, it will not be
possible to run the grabber. The file usually regenerates automatically over the course of
the next day, at which point it will be possible to run the grabber successfully.
There are no other reported ongoing issues.
