TxGateway

DVB-SIS Control Stream Generator

TxGateway is ENENSYS’ OneBeam orchestrator that operates at the head-end to fully control the DVB-T/T2 multiplex deterministic generation at the transmission site by the TxEdge, for SFN broadcasting. Until now two different distribution networks have been required to deliver a content bouquet to DTH and DTT (DVB-T/T2) viewers. OneBeam is the ENENSYS DVB-SIS solution to build DTT multiplex from one or two DTH sources. It relies on the same satellite transponder to deliver both DTH services and to feed DTT transmitters, reducing drastically the OPEX costs with fast ROI.

Applications

  • Use existing DTH services to build T/T2 multiplex
  • Backup DTT transmission site with DTH stream
  • Simultaneous FTA DTT and Pay TV DTH services
  • Covering DTT ‘black spots’ with DTH services
  • Regionalization support

Highlights

Proven Solution

Mature solution widely deployed since 2014 in several countries

High ROI

Reduce annual OPEX thanks to satellite bandwidth optimization

Standard Solution

OneBeam solution is fully compliant to the newly DVB-SIS standard, providing interoperability with any vendors.
