While DVB-T2 is designed to be backward compatible with DVB-T, not all DVB-T tuners can receive DVB-T2 signals. This is because DVB-T2 requires more advanced hardware and decoding capabilities. In order to receive DVB-T2 signals, a tuner must support the DVB-T2 standard and be compatible with the specific transmission parameters used in a given
DVB-T2 udbredelse; lysere blå. DVB-T2 ( Digital Video Broadcasting – Terrestrial, anden generation ), er en forbedret version af standarden DVB-T for mastebaseret fjernsyn. Standarderne er blevet udfærdiget af det EU-baserede konsortium DVB. DVB-T2 muliggør mindst 30% højere datahastighed (i bit/s) end DVB-T over samme spektrale
DVB-T2 succeeds in achieving a capacity increase of 50% over its predecessor DVB-T and any other DTT system. DVB-T2 supports SD, HD, UHD, mobile TV and digital radio, or any combination thereof.
ATSC coexists with the DVB-T standard, and with ISDB-T. A similar standard called ADTB-T was developed for use as part of China's new DMB-T/H dual standard. While China has officially chosen a dual standard, there is no requirement that a receiver work with both standards and there is no support for the ADTB modulation from broadcasters or
The main differences between a DVB-T and DVB T2 system is that the multiplexer shall be connected to a T2 gateway. This T2 gateway receives one or several multiplex e.g one per PLP from the multiplexer and encapsulates these datas into BaseBand Frames. The T2 gateway send the content to DVB T2 modulators via the T2 Modulator Interface protocol.
The second generation Digital Video Broadcasting by Satellite (DVB-S2) is defined in European Standard EN 302 307-1, which details these improved modulation and coding schemes, enhancing the efficiency of the space segment and giving the basis for providing interactive services. The extensions of the DVB-S2 system, defined to enlarge the fields
