You could direct this question directly to Humax Support at uksupport@humax-digital.co.uk they are pretty good at responding.
My view is they will have to. The Aura is Humax’s flagship product and they will want to keep it current for a few years. As it is based on Android TV, which is very flexible to change, I can’t see why the current Live TV App (which runs the Freeview Play recording, tuning, Guide etc.) cannot be modified to account for the proposed changes.
