TbEdge

Local BTS Generation

TbEdge is designed to generate a BTS stream At the transmission site for the delivery of ISDB-T/Tb multiplex over MFN or SFN Networks

BTS GENERATOR

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

MFN AND 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. The system’s deterministic approach allows it to handle the usual constraints of having the same content on the same frequency at the same time, vital with the predominance of SFN networks.

ONEBEAM – SATELLITE BANDWIDTH OPTIMIZATION

With OneBeam option, the TbEdge allows a standard (MPEG-2) transport stream to be used within the satellite delivery network, removing the need for proprietary equipment to access or monitor the content stream. But also, it optimizes 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
