T2Gateway for HDc

DVB-T2 Gateway (T2-base or T2-lite)

T2Gateway for HDc 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 the different physical layer pipes and generates T2-MI packets over ASI and IP.

DVB-T2 Gateway

Running at the head-end, the T2Gateway for HDc encapsulates the MPEG-2 TS streaming 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.
Also the T2Gateway for HDc enables SFN 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. It also supports MISO broadcasting to increase SFN performance.
The ENENSYS’ DVB-T2 Gateway supports the delivery of services over Multiple Physical Layer Pipes to define service-specific robustness. Thanks to the T2Gateway for HDc, operators can now differentiate easily services on a PLP basis with an offering that varies according to the robustness level. They can also improve coverage and offer regionalisation or ultra-local services.

ENENSYS’ patented technology, T2Guard, is the unique 1+1 redundancy mechanism that guarantees  a seamless switch-over in SFN and MFN modes to avoid any TV black-out during switch-over operation between two redundant T2 Gateways. The T2Guard applies with two T2Gateways that are redundant with ASIIPGuard, ENENSYS’ seamless ASI switch.

Applications

T2Gateway
  • DVB-T2 SFN/MISO build-up
  • DVB-T2 Mobile broadcasting
  • DVB-T2 Multi-PLP management
  • Seamless 1+1 and N+1 redundancy (patented technology)
  • DVB-T2 Regionalisation

Highlights

DVB-T2 Gateway with Multiple PLP support

Encapsulation of DVB/MPEG-2 Transport Stream(s) into a T2-MI stream

SFN Management

The T2Gateway for HDc enables SFN broadcasting over DVB-T2. It provides in-band (T2-MI) and out-of-band (T2-MIP) synchronization information to all modulators to generate the same data at the very same time over the same frequency.

1+1 and N+1 seamless redundancy

ENENSYS' patented technology, T2Guard, is the unique 1+1 or N+1 redundancy mechanism that guarantees a seamless switch-over in SFN and MFN to avoid any TV black-out during switch-over operation between 1+1 or N+1 redundant T2 Gateways.
