Description

in a not so distant future (2022) DVB-T Italy transmissions will move to DVB-T2 and use the codec HEVC.
In the last few days two HEVC test channels started transmissions with the new HEVC codec (at the moment on a DVB-T mux), but with a resolution of 1280x720.
Mapping the channel results with the UHDTV tag being auto-associated with the new channel.

2020-01-17 07:50:29.336 service-mapper: DVB-T Italy/177.5MHz/Test HEVC main10: success

So in this case the assumption from line 41 of the file src/input/mpegts/dvb_psi_lib.c

{ 0x1F, ST_UHDTV }, /* HEVC (assume all HEVC content is UHD?) */

would not be correct.

I'm sorry not to have a correction suggestion, but I thought anyway useful to point out this potential issue.

The required new feature would be to discriminate, if possible, channels using HEVC codec between UHD and HD (or even SD channels).
