Configuration - DVB Inputs - Muxes

Muxes are locations at which services can be found. On traditional networks (DVB-C, -T and -S), these are carrier signals on which the individual channels are multiplexed, hence the name. However, Tvheadend also uses the term ‘mux’ to describe a source for multiple IP streams - so an IP address, in effect.

Menu Bar/Buttons

The following functions are available:

Button Function
Save Save any changes made to the mux configuration.
Undo Undo any changes made to the mux configuration since the last save.
Add Add a new mux.
Delete Delete an existing mux.
Edit Edit an existing mux. This allows you to change any of the parameters you’d otherwise set when adding a new mux, e.g. delivery system, frequency, polarisation, etc.

Grid Items

The main grid items have the following functions:

Play : Downloads a playlist file (M3U or XSPF, depending on your startup options) so you can tune to the mux from an external application.

Enabled : Whether or not the mux is enabled and thus available.

EPG : EPG scan setup

Network : The name of the network to which the mux belongs. Networks are defined in Configuration -> DVB Inputs -> Networks - DVB-S or ATSC, for example.

Network UUID : The internal UUID reference for the network to which the mux belongs.

Name : Short name for the mux - derived from the frequency and polarisation if applicable (e.g. 10788V or 578MHz).

Original Network ID : The ONID is a code which uniquely identifies a network.

Transport Stream ID : The TSID is a code which identifies the network origination source or transmitter.

CRID Authority : The group responsible for the Content Reference Identifier for this mux. This is effectively a URL/URI to an authoritative source for programme data (e.g. series link).

Scan Status : Whether the mux is being scanned (ACTIVE), is planned to be scanned (PEND) or has reverted to idle scan (IDLE).

Scan Result : Whether there were any problems with the last scan of this mux.

Character Set : The character encoding for this mux (e.g. UTF-8).

# Services : The number of services found on this mux.

# Channels : The number of channels mapped to services found on this mux.

AC-3 Detection : Enables alternative detection methods for AC-3 audio.

URL : Mux URL.

Interface : The network interface/card on which the IPTV source can be found.

ATSC : Whether or not this is an ATSC IPTV source.

Mux Name : Text...

Service Name : Text...

Priority : The mux priority value (higher value = higher priority to use services from this mux). Value 0 means use the IPTV network priority value.

Streaming Priority : The mux priority value for streamed channels through HTTP or HTSP (higher value = higher priority to use services from this mux). Value 0 means use the standard streaming network priority value.

Environment (pipe) : List of environment variables for pipe (like PATH=/bin:/sbin) separated by spaces. The backslash character is handled like in URL.

Respawn (pipe) : Respawn the executed process when it dies.
