SmartGate vT
Software-based SFN Adapter for DVB-T
SmartGate vT is ENENSYS’ software-based SFN adapter for DVB-T. Running in a pure IP environment, it inserts synchronization data into a MPEG-2 TS to enable Single Frequency Network broadcasting.
Highlights
MIP Inserter with IP Inputs/Outputs
The SmartGate receives an MPEG-2 TS over IP, inserts MIP packet to synchronize all the DVB-T transmitters to broadcast the DVB-T multiplex over Single Frequency Networks. It performs bit rate adaptation and PCR restamping to match with DVB-T transmission parameters. It outputs the new MPEG-2 TS with MIP packet over IP.
SFN Management
The SmartGate provides synchronization (timestamp) information to all DVB-T transmitters to generate the same data at the very same time over the same frequency. It can also control individually each DVB-T transmitter to set remotely frequency offset or time offset information.
Software Based
The SmartGate runs in a pure software architecture independent from the Hardware. The virtual appliance which can be installed on standard servers allows high density and scability.
1+1 seamless redundancy - vGuard
ENENSYS' patented technology, vGuard, is the unique 1+1 or N+1 redundancy mechanism that guarantees seamless switch-over between redundant vBG DVB software to avoid any TV black-out. The vGuard applies with 1+1 or N+1 vBG DVB applications that operate in 1+1 or N+1 redundancy with IPGuardV2, ENENSYS' seamless IP switch.
Applications
