Booth no: SU6325 and in the ATSC 3.0 Broadcast/Workflow Area (NAB Futures Park)

ENENSYS Technologies is a leading designer and manufacturer of digital TV transmission systems. Its products sit between encoding/multiplexing and transmission, facilitating signal distribution over a wide variety of networks including IP. ENENSYS is the world leader in broadcast network technology, providing powerful optimization and regionalization solutions. The company covers the key standards such as DVB-T, DVB-T2, LTE Broadcast, ATSC and ISDB-T. It develops the technology embedded in its products and has released 15 patents to protect its intellectual property.



ENENSYS is using its global DTT experience and understanding of ATSC 3.0 to announce its entrance into the market for the new DTT transmission standard. As with its DVB successes, ENENSYS’ initial products – a ROUTE server, the ATSC3.0 Scheduler and an ATSC3.0 Modulator – sit between encoding and transmission. Using these products, broadcasters can deliver live streams directly from an encoder outputting DASH segments, while managing the ATSC3.0 physical parameters: MultiPLP allocation, SFN synchronization and so on. The technology, based on ENENSYS’ well-known modular platform HDc, has been developed to comply with the new standard, allowing broadcasters and network operators to take advantage of the benefits provided by it.


As well as its South Upper booth, ENENSYS is also exhibiting in the ATSC 3.0 Broadcast/Workflow Area (in the NAB Futures Park), where executives will be available to discuss in more depth the possibilities that ENENSYS’ technology opens up.


OneBeam ISDB-Tb – ENENSYS will also highlight its OneBeam ISDB-T/Tb DTT network optimization technology, designed for Latin American markets. OneBeam 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. Using an unusual 204 bytes MPEG transport stream, this also requires a bandwidth of 32 Mbit/s, regardless of how many channels or services are included, making it costly for content delivery over satellite to DTT headends. OneBeam ISDB-T/Tb 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. The BTS stream is generated in the last mile – i.e. at the TX site – supporting SFN. This also means that services can easily be monitored across the delivery network because of the standardized MPEG signal.


Using OneBeam, the same MPEG-2 transport stream that carries content for 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 regionalization.OneBeam ISDB-T image
