Aiming to enter the Latin American digital TV market, Enensys Technologies will present for the first time at Set Expo 2015 its OneBeam ISDB-T/Tb DTT optimisation technology which enables DTT signals to be transported through a satellite system.

onebeamOneBeam tackles key issues related to the specific nature of the broadcast transport stream (BTS) in ISDB-T/Tb, which is required for broadcasting ISDB-T/Tb signals. The BTS is composed of 204 bytes long MPEG-2 transport stream packets and requires a bandwidth of 32Mbit/s, regardless of how many channels or services are included.

OneBeam ISDB-T/Tb also allows a standard (MPEG-2) transport stream to be used within the delivery network, removing the need for proprietary equipment to deliver and receive the BTS stream.

Using OneBeam, the same MPEG-2 transport stream that carries content for direct-to-home (DTH) services can be reused for DTT services. From the DTH feed, the TbEdge system selects the services at each transmission site to build the new ISDB-T/Tb signal. The same solution can be used across multiple regions to offer service regionalisation.

"We have been exploring the LATAM market for some time, looking at how our technology can be adapted to deliver real benefits in an ISDB-T/ISDB-Tb environment," said Laurent Roul, product line manager at Enensys. "By re-engineering OneBeam to address the specific needs of the region, we're enabling network operators to effectively lower both Capex and Opex."
