DVB-T: Digital Video Broadcasting - Terrestrial is a universal terrestrial digital television standard in Europe.

DVB: Digital Video Broadcasting is a series of internationally recognized digital television public standards maintained by the DVB project.

DVB system transmission methods are as follows:


The main difference between these transmission methods lies in the modulation methods used, because they differ in the frequency bandwidth requirements they apply. DVB-S using a high frequency carrier uses a QPSK modulation method, DVB-C using a low frequency carrier uses a QAM-64 modulation method, and DVB-T using a VHF and UHF carrier uses a COFDM modulation method.

With the development of technology, Android TV box gradually replaced DVB as the mainstream TV product.
