​How about the DVB-T2



How about the DVB-T2:

DVB-T2 is a new generation of digital terrestrial transmission system standards recently developed by the DVB organization. It uses the latest modulation and coding techniques to efficiently use the terrestrial spectrum to provide video, audio and data services for fixed, portable and mobile receiving devices.

DVB-T2 uses OFDM modulation to transmit strong robust signals over a large number of subcarriers. Similar to DVB-T, DVB-T2 offers different modes, giving it great flexibility. For error protection, DVB-T2 uses the same error correction coding as DVB-S2. By using low density parity check coding (LDPC) and BCH coding, DVB-T2 can transmit strong robust signals in environments with large noise levels and interference.


DVB-T2 offers many options for parameters such as the number of carriers, guard interval, and pilot signal, so that overhead on the transmission channel is minimized. A new technique called "rotary constellation" provides it with additional robustness in poor channels. In order to meet the required receiving conditions (eg, indoor antenna or roof antenna reception), DVB-T2 also adopts a mechanism for robust adjustment of each service in the channel, ie, the transmission system can work in a suitable receiver. Power saving mode is achieved by decoding only a single program instead of the entire multiplexed program stream.
