This tab is used to configure the Electronic Program Guide (EPG) grabbing capabilities. Tvheadend supports a variety of different EPG grabbing mechanisms. These fall into 3 broad categories, within which there are a variety of specific grabber implementations.
The following functions are available:
Button | Function |
---|---|
Save Configuration | Save any changes made to the grabber configuration. |
Trigger OTA EPG Grabber | Force an immediate tune to the OTA EPG mux to request EPG updates. |
Help | Displays this help page. |
The cron lines looks like:
# * * * * * command to execute
# ┬ ┬ ┬ ┬ ┬
# │ │ │ │ │
# │ │ │ │ │
# │ │ │ │ └───── day of week (0 - 6 or Sunday - Saturday)
# │ │ │ └────────── month (1 - 12)
# │ │ └─────────────── day of month (1 - 31)
# │ └──────────────────── hour (0 - 23)
# └───────────────────────── min (0 - 59)
With the following cron special characters...
*
) : The asterisk indicates that the cron expression matches for all values of the field. E.g., using an asterisk in the 4th field (month) indicates every month./
) : Slashes describe increments of ranges. For example 3-59/15 in the 1st field (minutes) indicate the third minute of the hour and every 15 minutes thereafter. The form “*…” is equivalent to the form “first-last…”, that is, an increment over the largest possible range of the field.,
) Commas are used to separate items of a list. For example, using “MON,WED,FRI” in the 5th field (day of week) means Mondays, Wednesdays and Fridays.-
) : Hyphens define ranges. For example, 2000-2010 indicates every year between 2000 and 2010 AD, inclusive.#
) : Number-sign defines a start of a comment. The rest of line is ignored behind this character.Update channel name : Automatically update channel names using information provided by the enabled EPG providers.
Update channel number : Automatically update channel numbers using information provided by the enabled EPG providers.
Update channel icon : Automatically update channel icons using information provided by the enabled EPG providers.
Periodic save EPG to disk Interval : Writes the current in-memory EPG database to disk every x Hours (user defined), so should a crash/unexpected shutdown occur EPG data is saved periodically to the database (Re-read on next startup). Set to 0 to disable.
Module : Select which internal grabber to use.
Cron multi-line : Multiple lines of the cron time specification.
Force initial EPG scan at startup : … no comment
Cron multi-line : Multiple lines of the cron time specification.
EPG scan timeout in seconds : The multiplex (mux) is tuned for this amount of time at maximum. If EPG data are completed before this limit, the mux is released sooner.
Checkbox list : Checkbox list to enable/disable available modules. By default all grabbers should be enabled.
Checkbox list to enable/disable available modules. The path field contains the absolute path of the unix domain socket into which EPG data can be sent.
To send data to the socket use the command netcat -u SOCKET_PATH
.
Note: for some systems the netcat flags can vary so please consult the man page.
To apply any changes please use the [Save configuration button]
XMLTV/PyEPG - if you are using the internal versions of these modules then you must first configure them externally as Tvheadend provides no support for this. Nor does it provide the ability to pass command line options (for this use the external interface).
