TxEdge

DTH to DTT adapter

TxEdge is ENENSYS’ DVB-SIS Adapter for DVB-T/T2 that operates at transmitter sites in the OneBeam system. Running on the transmission site prior to the DTT transmitter, the TxEdge aims at receiving a DTH stream to build a new DVB-T/T2 multiplex. Operating in conjunction with TxGateway units at head-end, the TxEdge applies for building national or regional DVB-T or DVB-T2 multiplex.

Applications

  • Use existing DTH services to build DVB-T/T2 multiplex
  • Backup DTT transmission sites with DTH stream
  • Simultaneous FreeToAir DTT services and Pay TV DTH services
  • Covering DTT ‘black spots’ with DTH services
  • DVB-T/T2 regionalisation support
  • Emergency Warning System

Highlights

Standard solution

OneBeam solution is fully compliant to the newly DVB-SIS standard, providing interoperability with any vendors. The TxEdge rebuilds the DTT Multiplex based on a standardized DSACI and Framing & Timing packet.

Satellite bandwidth optimization - Reduce OPEX costs

Until now two different distribution networks have been required to deliver a content bouquet to DTH and DTT viewers. OneBeam is the ENENSYS end-to-end solution to build DTT multiplex from a DTH source. It relies on the same satellite transponder to deliver both DTH services and to feed DTT transmitters, reducing drastically the OPEX costs with fast Return On Investment (ROI).

Commercially Deployed

Since 2014, the TxEdge has been widely deployed all over the world to fasten the availabilities of DTT services and to cover at once 100% of the country. Over 2000 units are generating deterministic DTT streams to enable DVB-T/T2 services over SFN.

Covering 100% of population

The OneBeam solution is the unique solution to cover 100% of population with Digital Terrestrial Television services through satellite and terrestrial networks without duplicating network distribution bandwidth.

Regional Emergency Warning Service (rEWS)

As an option, the TxEdge offers the support of Emergency Warning System (EWS) to inform about immediate dangers such as earthquakes, flood, tsunami, It replaces all services in the T2 multiplex by one EWS service under trigger control. It can alert for the whole country or for a specific region. It allows to deliver several regional alerts at a time.
