NN6-T2 Gateway - DVB-T2 Gateway

NN6-T2 Gateway is ENENSYS DVB-T2 Gateway that allows network operators to broadcast DVB-T2 services, over Single Frequency Network (SFN) in particulary. Running at the head-end, the NN6-T2 Gateway encapsulates the MPEG-2 TS stemming from a typical DVB-T multiplexer into DVB-T2 BaseBand frames. It outputs the resulting DVB-T2 multiplex using the T2-MI (Modulator Interface) protocol through ASI and IP.

The NN6-T2 Gateway enables SFN MISO broadcasting over DVB-T2. It provides in-band and out-of-band synchronization information to all modulators to generate the same data at the very same time over the same frequency.

The ENENSYS' DVB-T2 Gateway supports the delivery of services over Multiple Physical Layer Pipes to define service-specific robustness. Thanks to the  NN6-T2 Gateway, Operators can now differentiate easily services on a PLP basis with an offering that varies according to the robustness level.
