Since I got a device which is both IPTV Player and DVB-T2 receiver, I'm guessing if I could compose an hybrid m3u list containing not only stream channels, but some DVB-T2 channels frequencies as well.
This way I would have something like this for the common stream channel:
#EXTINF:1, tvg-id="MyStreamChannel.com" tvg-logo=img/mystreamchannel.png" tvg-name="My Stream Channel HD" group-title="Favourites",My Stream Channel HD
http://my_stream_font.com/mystreamchannel.ts
... and something like this, for a DVB-T2 channel:
#EXTINF:1, tvg-id="TerrestrialChannel.com" tvg-logo=img/terrestrialchannel.png" tvg-name="Terrestrial Channel HD" group-title="Favourites",Terrestrial Channel HD
1_0_1_218C_4_13E_EEEE0000_0_0_0
Is it technically possible, maybe typing the code differently?
