NN6-T2 Gateway is ENENSYS’ DVB-T2 Gateway that encapsulates a DVB/MPEG-2 Transport Stream into a DVB-T2 multiplex, inserts synchronization data to allow Single Frequency Network broadcasting and generates T2-MI packets over ASI and IP. Running at the head-end, the NN6-T2 Gateway encapsulates the MPEG-2 TS stemming from a typical DVB-T multiplexer. It outputs the resulting DVB-T2 multiplex using the T2-MI (Modulator Interface) protocol through ASI and IP. The NN6-T2 Gateway is the central body of the operational DVB-T2 network as it provides in-band control and signaling to all the DVB-T2 modulators. When using Multiple PLP (Physical Layer Pipes) to provide service-specific robustness, the NN6-T2 Gateway enables all the modulators to generate the same data in a deterministic manner.
