TxEdge OneBeam
DTH to DTT adapter
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 end-to-end 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, drastically reducing the OPEX costs with fast ROI.
Highlights
DVB-T and DVB-T2 SFN Operations
Operating in conjunction with SmartGate units at head-end, the TxEdge is instrumental in building national or regional DVB-T or DVB-T2 multiplexes. The TxEdge receives one or two MPEG-2 TS at the input (ASI, IP or DVB-S/S2 ) and outputs a deterministic TS (in DVB-T) or T2-MI stream (in DVB-T2) to operate over Single Frequency Networks (SFN). It is supported by ENENSYS’ HDc chassis platform, enabling maximum density, flexibility, scalability and cost-efficiency.
Services Filtering and PSI/SI Update
The TxEdge selects the services from the DTH streams, allocates them to the different PLP in DVB-T2 and performs advanced PSI/SI processing to update PSI/SI information (PAT, CAT, PMT, BAT, NIT SDT, EIT) related to the filtered services.
Emergency Warning System
As an option, it offers Emergency Warning System (EWS) support, providing information about immediate dangers such as earthquakes, tsunami, etc. The TxEdge replaces all the services in the SFN/DTT multiplex by one EWS service under EWS trigger-control, generated by ENENSYS EWSCaster.
Standard solution
OneBeam solution is fully compliant to DVB-SIS standard, providing interoperability with any vendors. The TxEdge rebuilds the DTT Multiplex based on a standardized DSACI and Framing & Timing packet.
Applications
- Simulcast DTH services and Terrestrial DTT
- Create DTT multiplex from existing DTH services
- Secure DTT site feeds using DTH signal as redundancy
- Covering DTT ‘black spots’ with DTH services
- Deploy regional service broadcasting
- Implement Emergency Warning System
Other Benefits
- Straight-forward OPEX cost reduction
- Short-term Return on Investment (ROI)
- Unmatched field-proven technology
- DTT SFN roll-out
- Fully compliant with DVB-SIS standard
- Transparent for DTH receivers
- Reuse existing head-end system
