SmartGate vT2
Software-based DVB-T2 Gateway
SmartGate vT2 is ENENSYS’ software-based Gateway for DVB-T2 Single Frequency Network operation. Running in a pure IP environment, it gathers multiple MPEG-2 TS over IP and encapsulates them into a DVB-T2 multiplex to be broadcast over IP.
Highlights
Pure IP
The SmartGate vT2 is running in pure IP, it can receive several MPEG-2 TS over IP, with main and backup management. It encapsulates them into multiple PLP and delivers a 1+1 output stream over IP. The SmartGate vT2 can handle several virtual network interfaces to comply with main/backup scenario. The time synchronization is handled thanks to PTP or NTP.
Software-based and Virtualized
The SmartGate vT2 is a pure Software-based T2 Gateway. It can run on any COTS (Commercial Of The Shelf) server. Dedicated to virtualized environment, the SmartGate vT2 can be deployed using Docker container or Virtual Machine. Being virtualized, it can be installed along with other head-end function, typically software-based multiplexer and SmartGate vT2 can be installed on a same server.
Single Frequency Network
Running at the head-end, the SmartGate vT2 encapsulates one or several MPEG-2 Transport Streams over IP into DVB-T2 BaseBand frames. It outputs the resulting T2-base multiplex using the T2-MI (T2-Modulator Interface) protocol through IP. The T2Gateway 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) feature to provide service-specific robustness, the SmartGate vT2 enables all the modulators to generate the same PLP data in a deterministic manner.
Seamless 1+1 Redundancy
ENENSYS' patented technology, vGuard, is the unique 1+1 or N+1 redundancy mechanism that guarantees seamless switch-over between redundant SmartGate software to avoid any TV black-out. The vGuard applies with 1+1 or N+1 SmartGate vT2 applications that operate in 1+1 or N+1 redundancy with IPGuardV2, ENENSYS' seamless IP switch.
