Tvheadend

h1. Tvheadend with Telia IPTV

This page will describe 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?

h2. Tvheadend

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

h2. Ubuntu and Debian

Example configuration for @/etc/network/interfaces@ 

<pre>

iface eth1 inet dhcp

        vendor "TeliaSonera_VIP1910-9"

        post-up echo 2 > /proc/sys/net/ipv4/conf/eth1/force_igmp_version

        # rp_filter change is only needed if you have multiple network interfaces and the default route

        # is not routed to the interface receiving the multicast streams

        post-up echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

        post-up echo 0 > /proc/sys/net/ipv4/conf/eth1/rp_filter

</pre>

Example configuration for @/etc/dhcp3/dhclient.conf@ 

<pre>

interface "eth1" {

        vendor-class-identifier "TeliaSonera_VIP1910-9";

}

</pre>

h2. DHCP

A vendor class identifier used by the Telia "STB":http://en.wikipedia.org/wiki/Set-top_box must be present in the "DHCP":http://en.wikipedia.org/wiki/DHCP request, a known working identifier is "!TeliaSonera_VIP1910-9".

For dhclient this configuration line changes the vendor class identifier.

<pre>

vendor-class-identifier "TeliaSonera_VIP1910-9";

</pre>

h2. IGMP

<pre>

echo 2 > /proc/sys/net/ipv4/conf/eth1/force_igmp_version

</pre>

h2. 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 "RPF":http://www.wlug.org.nz/ReversePathFiltering or add a route to 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.

<pre>

echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

echo 0 > /proc/sys/net/ipv4/conf/$INTERFACE/rp_filter

</pre>

If you instead want to have RPF enabled you can add a route to the source of the multicast stream.

<pre>

route add -host $STREAM_SOURCE_IP gw $INTERFACE_GW dev $INTERFACE

</pre>
