21. Summary • Introduction of DVB-T2 can be possible without modifying the GE06 Plan (taking into consideration some constrains for given system parameters) same number of layers, higher bit rate/MUX • Modification of the GE06 Plan based on allotment extension can be possible in limited cases additional layers, same bit rate/MUX • Modification of the GE06 Plan based on allotment extension and implementing DVB-T2 system can be possible in limited cases additional layers, higher bit rate/MUX Regional Regulatory Seminar on Transition to Digital Terrestrial Television Broadcasting and Digital Dividend for Europe, Budapest, Hungary
