TbGateway for HDc

ISDB-T/Tb Gateway

TbGateway operates at the head-end to generate a BTS stream for SFN broadcasting or ISDB-T/Tb multiplex over MFN or SFN networks

TbGateway

BTS GENERATOR FOR SFN BROADCASTING

Operating at the head-end after the multiplexer, TbGateway aims at generating a BTS stream from an MPEG-2 Transport Stream (SPTS/MPTS). It can receive the incoming TS over ASI or IP, generates IIP packet with TMCC data and output a BTS stream so that ISDB-T/Tb transmitters can broadcast over SFN.

1+1 SEAMLESS REDUNDANCY – TBGUARD

ENENSYS’ patented technology, TbGuard, is the unique 1+1 redundancy mechanism that guarantees a seamless switch-over in SFN and MFN modes to avoid any TV black-out during switch-over operation between two redundant TbGateways. The TbGuard applies with two TbGateways that are redundant either with ASIIPGuard seamless ASI switch, or with IPGuard seamless IP switch.

ONEBEAM – SATELLITE BANDWIDTH OPTIMIZATION

With OneBeam option, the TbGateway 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.With OneBeam option, the TbGateway outputs the incoming MPTS with some additional information (TbMarkers) so that a standard and optimized MPEG-2 TS is distributed over satellite. At the transmission sites, the TbEdge generates the BTS stream based on TbMarkers for MFN or SFN broadcasting. With OneBeam, the TbGateway and TbEdge allow to combine DTH and DTT services as well as the broadcasting of regional content in SFN environment.
