General overview of DVB-T2 Lite
DVB-T2 Lite tutorial
The DVB T2-lite profile was added in June 2011 to the DVB-T2 standard v1.3.1 as Annex I.
The T2-Lite profile is mostly a subset of the DVB-T2 standard which is called now "DVB T2-base" profile.
Two additional code rates were added for improvement of mobile performance.
DVB-T2 Lite |
|
| FEC block size | LDPC 16k only |
| Code rate | 1/2, 3/5, 2/3, 3/4, 2/5,1/3 |
| Constellation | QPSK, 16QAM, 64QAM, 256QAM (up to code rate 3/5) |
| Rotated Constellation | Only for QPSK, 16QAM and 64QAM |
| Guard Interval | reduced set of combinaisons of FFT size, guard interval and pilot pattern. |
| FFT size | 2K, 4K, 8K, 16K, 16K ext. |
| Scattered pilots | PP8 not allowed |
| Max. Bandwidth | 4 Mb/s |
| P1 Signalling | new signalling for T2-mobile SISO/MISO |
| L1 Scrambling | optional scrambling of L1-post only or entire L1 |
The T2-Lite signal may either be transmitted as a stand-alone signal ie. in a regular PLP, or as a T2-Lite signal with FEF parts.
When a regular PLP is used the maximum data rates for the T2-Lite PLP shall not exceed 4 Mbit/s
The Future Extension Frame (FEF) carry a T2 Frame dedicated for mobile services and may have different modulation parameters (FFT size, Guard Interval, SFN/MISO, Pilot pattern) than the other T2 Frame to improve mobile reception. The FEF interval and size of the T2-Lite super frame can be defined in the T2Gateway. The maximum duration of a FEF part is 1 second.
In March 2012 the DVB-T2 Validation and Verification (V&V) task force, coordinated by the Technical Module TM-T2 working group, has organized the first plug fest dedicated to the validation and the verification of the T2-Lite profile of the DVB-T2 standard.
This plugfest was the opportunity for some manufacturers to perform interoperability testing of T2Gateway, modulator and receiver implementations using advanced DVB-T2-Lite profile.
