An easier approach is to use some new features in the post-0.20-SVN branch of MythTV to quickly look up the information. And, the best part is that you can use this new feature even if you're not using SVN--there's no need to upgrade ''any'' part of your MythTV installation.

* select "Channel Editor"

svn co http://svn.mythtv.org/svn/trunk/mythtv/contrib/master_iconmap

Starting with version 0.27, a single location for channel icons is used.

that runs ''mythbackend''. Typically, ''mythtv''. The location is defined

in the built-in ChannelIcons Storage Group (it's not necessary to create
 +
or change the ChannelIcons Storage Group.)
  
Doing so will create a directory called "master_iconmap" underneath the current directory. The master_iconmap directory contains a file called "channel_icons.pl", which can be used to retrieve channel icon information.

Channel Icon Download System

As of 0.21, MythTV includes a channel icon download system in mythtv-setup which will attempt to automatically download icons for channels in your database from services.mythtv.org. If it cannot find an icon it will present you with a list of options, an the ability to define your own search parameters.

To configure icon downloading in mythtv-setup:

  • run "mythtv-setup"
  • select "Channel Editor"
  • click on "Icon Download"
  • select either "Download all icons.." or "Rescan for missing icons.."


Universal Location

Starting with version 0.27, a single location for channel icons is used. By default, it will be in the .mythtv/channels directory of the user that runs mythbackend. Typically, mythtv. The location is defined in the built-in ChannelIcons Storage Group (it's not necessary to create or change the ChannelIcons Storage Group.)

Run mythtv-setup and get a new set of channel icons. They'll be stored in the directory above.

As of [6d10afe]cgitgithub mythweb will retrieve its icons from the same common directory.

The Services API (e.g. <backend>:6544/Guide/GetChannelIcon?ChanId=1021) endpoint works with this feature as of [85462fb]cgitgithub.

Symlinks added for prior MythTV versions, duplicate channels directories and any ChannelIcons directories and their contents can be removed.

Pre 0.27 Instructions

By default the icon will be downloaded to the /home/<user>/.mythtv/channels directory. This is not very friendly when you have multiple frontends and wish them all to share the icons. One method to get around this is to use a symlink for this directory that directs to a network located directory that all your frontends have access to, say /var/mythtv/channels for example.

Before downloading the icons, do the following, or similar as per your distribution:

rm ~/.mythtv/channels -rf
sudo mkdir /var/mythtv/channels
sudo chown <user>:<group> /var/mythtv/channels
ln -s /var/mythtv/channels ~/.mythtv/channels

You will want to run

rm ~/.mythtv/channels -rf
ln -s /var/mythtv/channels ~/.mythtv/channels

for all the users that can run MythTV as well.

Channel Icon Sources

One of the best sources of channel icons is http://www.lyngsat-logo.com/ . There, you can browse the available icons and choose those appropriate for your system. However, doing so can be a lot of work (requiring many page hits and a lot of time). Once downloaded you should put the resulting JPEG files into .mythtv/channels/ for the user running the front-end. To add them to a channel you will need to run mythtv-setup and go to the channel editor and specify the icon file name for each channel.

Another source of channel icons is http://www.iconharmony.com/ which is targeted for icons for the harmony remote. Some of the available icons are more stylized than the official icon (the person running the site is a graphic artist). As with the previous source, finding an appropriate icon can be a lot of work.
