Tvheadend

= Tvheadend with Telia IPTV =

This page will describe of how to configure Tvheadend to receive multicast TV streams via your Telia broadband connection, note that you must be subscribed to the TV service or else the service is not provisioned to your customer port.

TODO: Not using Telia switch, VLAN ID 825?

== Tvheadend ==

TODO: Add groups 239.16.16.1-255, link to file with channel names etc

== Ubuntu and Debian

Example configuration for {{{/etc/network/interfaces}}}
{{{
iface eth1 inet dhcp
vendor "TeliaSonera_VIP1910-9"
# rp_filter change is only needed if you have multiple network interfaces
# and the default route is not routed out on the multicast interface
post-up echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
post-up echo 0 > /proc/sys/net/ipv4/conf/eth1/rp_filter
}}}

== DHCP ==

The vendor class identifier must be change, a known working identifier is "TeliaSonera_VIP1910-9"

For dhclient this configuration line changes the vendor class:
{{{
vendor-class-identifier "TeliaSonera_VIP1910-9";
}}}

== Setup with multiple network interfaces ==

If the default route is not routed out on the interface used to receive the multicast stream you must disable [http://www.wlug.org.nz/ReversePathFiltering RPF] or add a route for the source IP used in the received stream. Otherwise the packets will be dropped by the kernel because of RPF and will not be passed on to Tvheadend.

You can disable RPF in Linux by changing the {{{rp_filter}}} file in the proc filesystem
{{{
# echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
# echo 0 > /proc/sys/net/ipv4/conf/$INTERFACE/rp_filter
}}}
It is imported to change both of them, if {{{all/rp_filter}}} is 1 the interface specific configuration is ignored

If you instead want to have RPF enabled you can add a route to the source of the multicast stream
{{{
route add -host $STREAM_SOURCE_IP gw $INTERFACE_GW dev $INTERFACE
}}}
