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.

The columns 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

  • Disable: Disable the EPG scan

  • Enable (auto): Enable the EPG scan (when some services from this mux are assigned to channels)

  • Force (auto): Force the EPG scan (everytime when the EPG scan is triggered)

  • Only EIT: Do only EIT EPG scan (when some services from this mux are assigned to channels)

  • Only UK Freesat: Do only UK Freesat EPG scan (when some services from this mux are assigned to channels)

  • Only UK Freeview: Do only UK Freeview EPG scan (when some services from this mux are assigned to channels)

  • Only Viasat Baltic: Do only Viasat Baltic EPG scan (when some services from this mux are assigned to channels)

  • Only OpenTV Sky UK: Do only OpenTV Sky UK EPG scan (the TSID must match in the skyuk configuration file)

  • Only OpenTV Sky Italia: Do only OpenTV Sky Italia EPG scan (the TSID must match in the skyit configuration file)

  • Only OpenTV Sky Ausat: Do only OpenTV Sky Ausat EPG scan (the TSID must match in the ausat configuration file)

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.

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.

URL : Mux URL.

  • udp://: Raw MPEG-TS UDP packets

  • rtp://: MPEG-TS UDP packets with RTP header

  • http://: HTTP stream (MPEG-TS)

  • https://: Secure HTTP stream (MPEG-TS)

  • pipe://: Read standard output from an external program. If the program name does not have a forward slash (/) as the first character, the PATH environment variable is used to find the program name in all directories specified by PATH. Additional arguments may be separated using spaces. A raw MPEG-TS stream is expected. The string ${service\_name} is substituted with the service name field contents. The backslash character (\) means “take the next character as-is” (usually space or the backslash itself - what’s termed “escaping” a character).

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

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

PMT Descriptor 0x06 = AC-3 : Whether or not the empty PMT descriptor 0x06 defaults to the AC-3 stream. Some Chinese cable providers are using this. If unsure, keep this off.

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

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

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

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