TbEdge

Local BTS Generation for ISDB-T/Tb

TbEdge is Enensys’ versatile solution to generate a BTS stream at the transmission site for the delivery of ISDB-T/Tb multiplex over MFN or SFN Networks. Acting as a Local BTS generator, it receives the incoming TS over ASI, over IP or directly from a DVB-S/S2 satellite input. Working as a standalone product, or in a conjuntion with a TbGateway, the TbEdge covers several use cases, BTS decompression, BTS generation from a DTH stream with OneBeam single illumintation option, and BTS generation.

Applications

TbEdge
  • ISDB-T/Tb broadcasting
  • BTS Decompression
  • SFN broadcasting support
  • Regionalization support
  • Use existing DTH services to build ISDB multiplex
  • Backup DTT transmission site with DTH stream

Highlights

BTS Generation

Operating at the transmission site prior to the ISDB-T/Tb transmitter, the TbEdge aims at generating a BTS stream from a MPEG-2 TS (SPTS/MPTS). It can receive the incoming TS over ASI, over IP or directly from a DVB-S/S2 satellite input. It generates IIP packet with TMCC data and outputs a BTS stream for the ISDB-T/Tb transmitter.

MFN & SFN Compliant

By default, The TbEdge is designed to deliver a local BTS stream for Multiple Frequency Networks (MFN) operation. It can support Single Frequency Network (SFN) broadcasting with OneBeam option. Based on a deterministic approach, all TbEdge will deliver the same content on the same frequency at the same time, to create an SFN cell.

BTS Decompression

Thanks to the decompression feature, upon reception of a compressed BTS coming either from a TbGateway, or from any equipment generating a compressed BTS, the TbEdge will perform the decompression to deliver a BTS to the modulator with the expected bitrate.

DTH and ISDB-Tb combination

With OneBeam option, a standard MPEG-2 transport stream is distributed over satellite to optimize the satellite bandwidth by delivering only useful information providing significant cost savings. Locally, the TbEdge generates the BTS stream based on TbMarkers generated by the TbGateway prior the satellite distribution. OneBeam allows to combine DTH and DTT services as well as the broadcasting of regional content in SFN environment.

Services Filtering and PSI/SI Update

The TbEdge supports multi-layer ISDB-Tb applications. It allows the filtering of incoming services, updates some SI information such as the service name, virtual channel number and enables to allocate the filtered services or PID to the different layers. Optionally, it can support BISS-1 descrambling. Combined with the ENENSYS TSDescrambler, it can descramble any services with a ProCAM module inserted in the TSDescrambler.

Emergency Warning System

As an option, it offers the support of Emergency Warning Broadcast System (EWBS) to inform about immediate dangers such as earthquakes, tsunami,... The TbEdge supports EWBS signaling and is capable to modify the emergency descriptor information.

ISDB-Tb and DTH combination with OneBeam Tb

With OneBeam option, TbEdge is capable to generate a BTS for SFN broadcasting based on DTH stream.
