Virtual Broadcast Gateway

Virtualized MIP inserter and Single Frequency Adapter

Running at the head-end after the DVB multiplexer, the vBG is ENENSYS DVB virtual broadcast gateway enabling multiplex transmission of DVB-T over SFN networks. The vBG DVB addresses customers needs for full software environment. Future-proof and  based on standard architecture, the vBG is fully independent from specific hardware.

Applications

  • DVB-T SFN broadcasting
  • DVB-T rebroadcasting
  • Virtualized architecture
  • Pure SW and IP environment
  • High density

Highlights

MIP Inserter with IP Inputs/Outputs

The DVB Virtual Broadcast Gateway 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 DVB Virtual Broadcast Gateway 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 DVB Virtual Broadcast Gateway 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.

vBG architecture with redundancy

The vBG is installed after the multiplexer, it can be used 1+1 redundancy thanks to the vGuard feature
