SmartGate T2

DVB-T2 Gateway

SmartGate T2 is ENENSYS’ DVB-T2 Gateway module (T2-base or T2-lite) that encapsulates one or several MPEG-2 Transport Streams into a DVB-T2 multiplex, inserts synchronization data for single frequency network broadcasting, allocates data into different physical layer pipes (PLP) and generates T2-MI packets over ASI and IP.

Highlights

Over 800 SmartGate T2 deployed worldwide

Since 2009, the world's first DVB-T2 Gateway has been deployed in all the continents to enable the roll-out of DVB-T2 services in single PLP and multiple PLP. All the major transmitter manufacturers have bought the ENENSYS SmartGate T2 to guarantee the interoperability in the network.

DVB-T2 Gateway with Multiple PLP support

The SmartGate T2 supports the encapsulation of MPEG-2 Transport Streams into up to 8 PLPs. As of today, the SmartGate T2 has been deployed in several multiple-PLP DVB-T2 services to enable regionalization but also fixed and mobile services in the same T2 signal.

SFN Management

The SmartGate T2 enables SFN broadcasting over DVB-T2 throughout several reference clock mechanisms.
It provides in-band (T2-MI) relative or absolute timestamp information to all modulators to generate the same data at the very same time over the same frequency. It also supports MISO broadcasting to increase SFN performance.

High density solution

The SmartGate T2 runs in the ENENSYS HDc chassis that can embed up to 6x SmartGate T2 modules in 1U: the same chassis can output up to 6 T2-MI streams over ASI or IP. The SmartGate T2 can be embedded in the same 1U chassis with other modules such as the InverTS, the ASIIPGuard or the IPGuardV2.

1+1 and N+1 seamless redundancy

ENENSYS' patented technology, T2Guard, is the unique 1+1 or N+1 redundancy mechanism that guarantees seamless switch-over between redundant SmartGate T2 to avoid any TV black-out. Combined with the ENENSYS seamless switch ASIIPGuard or IPGuardV2, the SmartGate T2 offers a unique seamless SFN or MFN switch-over.
