DVB-T, DVB-T2, HEVC, Mpeg2, Mpeg4

I am investigating the relationship between the broadcast formats, DVB-t and T2 and the codec formats HEVC, MPEG2 & 4 on TVs in Australia.
Unfortunately, the manuals supplied by most manufacturers are incomplete when it comes to this information, eg it will list the TV as being DVB-T2 but not mention anything about its MPEG4 and HEVC capabilities. But I believe that some of the broadcast standard go hand in hand with the codec formats. eg DVB-T capable TVs must be able to decode MPEG2, I also believe that a DVB-T2 TV must also be able to decode HEVC codec. Does anyone any information regards these relationships? For example, are my above beliefs, correct? Is there a similar relationship between DVB-T2 and Mpeg4.

DVB-T2 is backward-compatible, so all DVB-T transmissions will still be decoded.

HEVC, which is also known as H.265 is included.

There's heaps of info available via Google etc searches.
