Oh yeah
Not overly familiar with digital telly in Italy. The number of channels depends on how many muxes there are, their capacity and how high (or low) a bit rate you want to use to broadcast your service.
It's basically a balance between quality (in picture terms not content

) and quantity. If you care sod all about quality then you can have loads of quantity. If you DO care about quality however you can't have loads of quantity. Given the same total capacity of the system.
Changing from DVB-T to DVB-T2 would up the capacity so you could have increased quality at the same quantity (oh look a pig just flew past the window

) or more likely more quantity at the current quality level. Or if we are unlucky more quantity and less quality.
