This How-To describes a procedure to harvest EPG data for MythTV using the nexTView protocol. This method is only interesting for those who have access to the European continent. This data is not sent in the rest of the world.

Required Software

nxtvepg - This software provides an interface to the nexTView protocol, both in console and as a GUI (X) application. 2.7.5 should be the lowest version that you should install.

[1]

Setup and Testing

Get the latest software as described above. Now start nxtvepg to do some tests. Try to get your EPG data. If this works, you can exit nxtvepg. Now try to harvest data to be exported to XMLTV format. This is done with the following command:

nxtvepg -daemon -acqonce full -provider d92 -nodetach

This runs nxtvepg without GUI and acquires the provider d92 (Kabel1 in Germany) and leaves the console locked until the harvesting is done. Be patient - this may take a long time (in the range of 30 minutes to an hour). Now we will try to export the harvested data to a XML file.

nxtvepg -provider d92 -dump xml > /tmp/nxtvepgtest.xml

You should now have a file in /tmp of about 1 Megabyte size. Open it up in your favorite editor to check for correctness. Note down the IDs for each channel, as you might need these later on.

Automatic import channel data

The following script should scan for channels and add these to MythTV. I recommend using this only if you have not added channels manually:

autochannel.sh:
Code:
#!/bin/bash
# Scan tv source for channel information and insert it into MythTV's database
# Written by zagibu@gmx.ch
# Distributed under the terms of the GNU General Public License v2
# Date: 21.05.2005

version=v0.1
command_list="scantv mysql head tail cut wc"
autochannel=scantvdump_$(date +\%d).txt

# Verify that each command we use exists
for command in $command_list; do
        path=$(which $command | grep "no $command in")

        if [ ! -x $(which $command) -a "$path" ]; then
                echo -e "\n\nERROR: $command not found! Check your \$command_lis
t and/or your \$PATH"
                exit -1
        fi
done

echo -e "\nScanner $version"
echo "============"

# Scan input for channel information and dump it into a file
scantv -a -f europe-west -n PAL -o $autochannel

# Count lines of scantv dump
lines=$(cat $autochannel | wc -l | cut -f1 -d' ')
# Subtract amount of header lines (7)
lines=$(expr $lines - 7)

# Read each channel entry of scantv dump
for (( i=0; i<$lines; i=$i+3 ))
do
        chanid=$(expr $(expr $i + 3) / 3)
        channum=CH$chanid
        freqid=$(tail -n$(expr $lines - $(expr $i + 1)) $autochannel | head -n1
| cut -f3 -d' ')
        name=$(tail -n$(expr $lines - $i) $autochannel | head -n1)
        name=$(echo $name | cut -f2 -d'[' | cut -f1 -d']')
        callsign=$(cat cnilist | grep "=$name=" | cut -f3 -d'=')
        xmltvid=$(cat cnilist | grep "=$name=" | cut -f1 -d'=')

        # Insert gathered channel info into mythtv's db
        mysql -umythtv -pmythtv mythconverg -e"INSERT INTO channel (chanid, channum, freqid, sourceid, callsign, name, xmltvid, tvformat) VALUES ($chanid, '$cha
nnum', '$freqid', 1, '$callsign', '$name', '$xmltvid', 'PAL');"
done 

Channel list

Add nxtvepg data and Sync Clock

The following scrip allows to automate the process we tested above of harvesting epg data. Make sure to change the provider code.

#!/bin/bash
# Get time and epg data from teletext, then insert it into MythTV's database
# Written by zagibu@gmx.ch
# Distributed under the terms of the GNU General Public License v2
# Date: 21.05.2005

version=v0.1
command_list="nxtvepg hwclock mythfilldatabase"
epgdump=nxtvepgdump_$(date +\%d).txt

# verify that each command we use exists
for command in $command_list; do
        path=$(which $command | grep "no $command in")

        if [ ! -x $(which $command) -a "$path" ]; then
                echo -e "\n\nERROR: $command not found! Check your \
                $command_list and/or your $PATH"
                exit -1
        fi
done

echo "Adjusting time (using teletext as reference)..."
# Set system time to current teletext time
nxtvepg -clock set
# Save system time to hardware clock
hwclock --systohc

echo "Acquiring NexTView EPG from provider SF 1..."
# Acquire [[Next View]] EPG from provider "SF 1"
nxtvepg -acqonce full -daemon -nodetach -provider 04C1
# Dump current EPG data into a file (xmltv5 format must be set in .nxtvepgrc)
nxtvepg -dump xml -provider 04C1 > $epgdump

echo "Loading [[Next View]] EPG data into MythTV..."
# Insert EPG data into MythTV's database
mythfilldatabase --file 1 -1 $epgdump

echo "All processes completed. Enjoy your [[Myth Box]]!"
