I decided to give my DVB-T usb dongle (Realtek RTL2838) another go with the Raspberry Pi and TvHeadEnd. As I thought the newer version of Raspbian if available might address the condition I had previously where I had no dvb device after plugging it in. Older post found here.
It would appear it was a good to check this out again.
I downloaded the latest Raspbian available from the Raspberry Pi site. The version available at the time of this post is the one below;
2013-12-20-wheezy-raspbian.zip
I installed to an SD card and booted my Raspberry Pi.
I plugged in my Realtek RTL2838 tuner and it detected fine and when I checked for the dvb device structure, it was populated all correctly, which never happened previously at all.

Next I configured other tools before compiling and installing the TvHeadEnd per the steps below;
sudo apt-get install unzip libcurl4-openssl-dev pkg-config git build-essential dvb-apps
cd ~
git clone https://github.com/tvheadend/tvheadend
cd tvheadend
./configure
make
sudo make install
At which point I executed the binary via “tvheadend -C” and I could now access the web interface for the TvHeadEnd software via http://raspberrypi_ip:9981/ where I could now see my dvb tuner was detected.
At this point you now have to configure the network and channels according to your region. Can be a bit tricky, but I followed the info available at the post here (step 14). This helped me make sense of the sequence of actions.
Below is a screen grab showing VideoLan Client from my Windows 7 desktop and a web browser in the background attached to the TvHeadEnd which is running on the Raspberry Pi with the RTL2838 tuner.
EDIT: And to get my TvHeadEnd to auto start with boot I performed the following additional steps.
Created /etc/init.d/tvheadend file with the contents below;
#!/bin/bash
### BEGIN INIT INFO
# Provides: tvheadend
# Required-Start: $local_fs $remote_fs $network
# Required-Stop: $local_fs $remote_fs $network
# Should-Start: $syslog
# Should-Stop: $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1
# Short-Description: start/stop tvheadend Server
### END INIT INFO
TVHNAME="tvheadend"
TVHBIN="/usr/local/bin/tvheadend"
TVHUSER="tvheadend"
TVHGROUP="tvheadend"
PIDFILE=/var/run/$TVHNAME.pid
start() {
if [ -e $PIDFILE ]; then
PID=$(ps ax | grep -v grep | grep -w $(cat $PIDFILE) | awk '{print $1}')
if [ -n "$PID" ]; then
echo "$TVHNAME already running (pid $PID)."
exit 1
fi
fi
echo -n "Starting tvheadend: "
start-stop-daemon --start --background --pidfile $PIDFILE --make-pidfile --user ${TVHUSER} --exec ${TVHBIN} --
-u ${TVHUSER} -g ${TVHGROUP} -f -C
echo "Done."
}
stop() {
if [ -e $PIDFILE ]; then
PID=$(ps ax | grep -v grep | grep -w $(cat $PIDFILE) | awk '{print $1}')
if [ -n "$PID" ]; then
echo -n "Stopping $TVHNAME: "
start-stop-daemon --stop --quiet --pidfile $PIDFILE --name ${TVHNAME}
echo "Done."
else
echo "$TVHNAME is not running."
fi
else
echo "$TVHNAME is not running."
fi
}
status() {
if [ -e $PIDFILE ]; then
PID=$(ps ax | grep -v grep | grep -w $(cat $PIDFILE) | awk '{print $1}')
if [ -n "$PID" ]; then
echo "$TVHNAME is running (pid $PID)."
else
echo "$TVHNAME is not running."
[ -e $PIDFILE ] && exit 1 || exit 3
fi
fi
}
case "$1" in
start) start ;;
stop) stop ;;
restart) stop && sleep 2 && start ;;
*) echo "Usage: $0 [start|stop|restart|status]" && exit 1 ;;
esac
exit 0
Now set the script as executable using below;
sudo chmod 755 /etc/init.d/tvheadend
Create a tvheadend group
sudo groupadd tvheadend
Create a tvheadend user that is part of the video group and tvheadend group.
sudo useradd -g tvheadend -G video -m tvheadend
And now set the initscript tvheadend to startup and shutdown as system does
sudo update-rc.d tvheadend defaults
