Can you decode this signal with a cheap consumer DVB-T2 set-top box?

If yes, the the question becomes "where can I find the standards definition
for DVB-T2 so that I can go about writing an SDR for it". If not, then the
question is whether in your particular area, the signal is really DVB-T2 at
all.

In the UK we use a mixture of DVB-T and DVB-T2. Older TVs and set-top boxes
have only DVB-T, and DVB-T2 is currently only being used for HD broadcasts.

As I understand it, DVB-T2 provides around 40% higher bitrate for the same
amount of spectrum and power, but uses a different modulation scheme so the
older receivers can't use it. I believe the UK also uses different codecs
(MPEG-2 for DVB-T, MPEG-4 for DVB-T4)

You can get some pointers to the technical specs at the ever-truthful
wikipedia:
