The problem is that the Component Descriptor contains only the codec (MPEG2 / H264 / H265) - not the resolution.
So it's always a good guess that MPEG2 is SD, H264 is HD and H265 is UHD.
But for DVB-T this guess is not correct.
In my case it is clear that VLC reads codecs correctly when playing pure .ts file. That defines is transmission SD, HD or 4k. In VDR live these got mixed in a way that DVB-T2 based HD stream is shown in live as SD and DVB-S2 based 4K stream as pure HD like non 4K DVB-S2 streams. So clearly Live fails here a bit compared to VLC.
This is not very significant failure but failure still.
Here is my four separate info files from Tokyo olympics partly from Eurosport DVB-S2 and partly from Finnish national broadcaster DVB-T/T2. Value G follows SD/HD markings in VDR and that clearly fails with antenna based HD stream....which could be a broadcaster failure for sure.
