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
