Future digital receivers for DAB+/DRM+ only
At present DAB is only available as additional function in form of mere DAB-receivers.
The market for Hybrid Receivers is only poorly developed.
Today, advanced CMOS processes already allow highly integrated one chip solutions.

Digital radio in Japan
Based on the Japanese terrestrial TV-system, the so-called „Sound Broadcasting“ system was supposed to be launched already three years ago.
On enquiry a NHK Manager explained:SB in Japan is the same nightmare as DAB in Europe.
According to our information the system has „fallen asleep“.
Kids watch 1 segment video/audio TV programmes on their mobile phones.
