+               <description>&lt;p&gt;The Norwegian nationwide open channel
+&lt;a href=&quot;http://www.frikanalen.no/&quot;&gt;Frikanalen&lt;/a&gt; is still going
+strong.  It allow everyone to send the video they want on national
+television.  It is a TV station administrated completely using a web
+browser, running only &lt;ahref=&quot;https://github.com/Frikanalen&quot;&gt;Free
+Software&lt;/a&gt;, providing a REST api for administrators and members, and
+with distribution on the national DVB-T distribution network RiksTV.
+But only between 12:00 and 17:30 Norwegian time.  This has finally
+changed, after many years with limited distribution.  A few weeks ago,
+we set up a Ogg Theora stream via icecast to allow everyone with
+Internet access to check out the channel the rest of the day.  This is
+presented on
+&lt;a href=&quot;http://www.frikanalen.tv/se&quot;&gt;the Frikanalen web site now&lt;/a&gt;.  And
+since a few days ago, the channel is also available
+via &lt;a href=&quot;https://www.uninett.no/iptv-tilgang&quot;&gt;multicast on
+UNINETT&lt;/a&gt;, available for those using IPTV TVs and set-top boxes in
+the Norwegian National Research and Education network.&lt;/p&gt;
+
+&lt;p&gt;If you want to see what is on the channel, point your media player
+to one of these sources.  The first should work with most players and
+browsers, while as far as I know, the multicast UDP stream only work
+with VLC.&lt;/p&gt;
+
+&lt;ul&gt;
+  &lt;li&gt;&lt;a href=&quot;http://video.nuug.no/frikanalen.ogv&quot;&gt;http://video.nuug.no/frikanalen.ogv&lt;/a&gt;&lt;/li&gt;
+  &lt;li&gt;udp://@224.17.43.129:1234&lt;/li&gt;
+&lt;/ul&gt;
+
+&lt;p&gt;The Ogg Theora / icecast stream is not working well, as the video
+and audio is slightly out of sync.  We have not been able to figure
+out how to fix it.  It is generated by recoding a internal MPEG
+transport stream with MPEG4 coded video (ie H.264) to Ogg Theora /
+Vorbis, and the result is less then stellar.  If you have ideas how to
+fix it, please let us know on frikanalen (at) nuug.no.  We currently
+use this with ffmpeg2theora 0.29:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+./ffmpeg2theora.linux &amp;lt;OBE_gemini_URL.ts&amp;gt; -F 25 -x 720 -y 405 \
+ --deinterlace --inputfps 25 -c 1 -H 48000 --keyint 8 --buf-delay 100 \
+ --nosync -V 700 -o - | oggfwd video.nuug.no 8000 &amp;lt;pw&amp;gt; /frikanalen.ogv
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;If you get the multicast UDP stream working, please let me know, as
+I am curious how far the multicast stream reach.  It do not make it to
+my home network, nor any other commercially available network in
+Norway that I am aware of.&lt;/p&gt;
