SmartGate ISDB
ISDB-T/Tb Gateway
SmartGate operates at the head-end to generate a BTS stream for SFN broadcasting or ISDB-T/Tb multiplex over MFN or SFN networks
Highlights
BTS GENERATOR FOR SFN BROADCASTING
Operating at the head-end after the multiplexer, SmartGate 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 SmartGate ISDB. The TbGuard applies with two SmartGate that are redundant either with ASIIPGuard seamless ASI switch, or with IPGuard seamless IP switch.
ONEBEAM - SATELLITE BANDWIDTH OPTIMIZATION
With OneBeam option, the SmartGate ISDB 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 SmartGate 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 TxEdge ISDB generates the BTS stream based on TbMarkers for MFN or SFN broadcasting. With OneBeam, the SmartGate and TxEdge allow to combine DTH and DTT services as well as the broadcasting of regional content in SFN environment.
BTS Compression
Enensys SmartGate can operate as a BTS compressor, receiving a
standard BTS, the SmartGate outputs the incoming stream into a
compressed BTS stream with MPEG-2 TS packets of 188 bytes length.
In compression mode, the SmartGate will remove the null packets
and 16 last bytes from the BTS’ packets to obtain a standard TS.
