How to convert the DVB-T equipment that has already met the European standard to DMB-T?

How to convert DVB-T equipment that has already been implemented in the European standard to DMB-T?
National departments at all levels, especially the constituent units of the National Digital TV Leading Group, have emphasized on different occasions that
it is necessary to formulate terrestrial digital TV standards with independent intellectual property rights, rather than choosing other standards. This
means that the system that implements the European DVB-T standard will not only fail to meet the requirements of the national standard, but also face
the risk of paying huge patent fees to foreign countries after DVD.
So far, DMB-T has fully met the application of Chinese terrestrial digital TV in terms of technological advancement, industrialization, and operational feasibility
. For operating departments that have already installed European DVB-T equipment
, especially those that have already installed many terminal receiving set-top boxes, this part of the investment will mean great risks.
Since Tsinghua DMB-T standard and the European DVB-T standard use completely different technical systems, from error
correction coding, signal modulation, frame structure, synchronization technology, etc., it is impossible
to solve it .
From the perspective of engineering practice, the switch from European standard DVB-T to Tsinghua DMB-T system requires the replacement of
front-end equipment such as the exciter and single frequency network adapter, especially the receiving set-top box.
