Providing some general clarification here to avoid further confusion:
1.) The DVB-T2 stick contains two different receiver chips from Realtek and Panasonic. Both can be used to receive DVB-T, but only the Panasonic chip is capable of demodulating the more complex DVB-T2 signal. Current Vero 4K kernel does not yet support the Panasonic chip and thus only “sees” DVB-T multiplexes. Depending on the country (check http://en.dtvstatus.net/) either only DVB-T or DVB-T2 or both are active.
2.) For HD video decoding, independent of the transmission type, in many cases H.264 is used. H.264 is a rather old and not too complex video coding algorithm and thus even devices like the Raspberry are able to decode it. In contrast, DVB-T2 HD in Germany uses the newer and more powerful H.265 coding, also known as HEVC. This one is too complex for the Raspberry, whereas the Vero 4K is powerful enough to handle it.
