Managing T2-MI signals with the RANGERNeo 2 field strength meters

July 9, 2015.

In DVB-T2 broadcast technology, the multiplexers are delivering one or more MPEG-2 TS signals to a T2 Gateway. The T2 Gateway is assigning each MPEG-2 TS to a specific PLP (Physical Layer Pipe) and building up a more complex multi-layered signal known as T2-MI (T2 Modulator Interface).

The T2-MI signal includes synchronization data for SFN broadcast and furnishes the DVB-T2 modulators with modulation parameters setup for each PLP.

T2-MI is exclusively used in the link between the T2 Gateway output and the DVB-T2 modulators input, and transported via either TS-ASI or IP.

The RANGERNeo 2 field strength meters will allow the T2-MI reception through its TS-ASI, RF or IP (multicast) input, letting the user record the T2-MI signal into a file and play out that file containing the recorded T2-MI through the meter's TS-ASI output.
