Hughes Leads the Industry in Promoting Adoption of DVB-S2X Standards for Satellite Transmission 


Company Contributes Essential Patents to New Licensing Pool, Making Standards Available Widely.

Germantown, MD, March 27, 2019Hughes Network Systems, LLC (HUGHES), the global leader in broadband satellite networks and services, today announced its participation as a founding member of and major patent contributor to the DVB-S2X joint licensing patent program (“patent pool”). DVB-S2X comprises the technical standard for satellite transmission, an extension of the DVB-S2 standard, that enables higher throughputs and greater bandwidth efficiency. The new patent pool makes essential DVB-S2X technology easily accessible to innovators regardless of industry, ensuring engineers around the world can leverage the extended industry standard. 

“Built into all satellite terminals (VSATs) of the Hughes JUPITER™ System, DVB-S2X covers a wide range of transmissions – from UHD television broadcasting to Internet traffic, enabling the high performance of the industry’s HTS (High-Throughput) satellites,” said Dr. Lin-Nan Lee, vice president, Advanced Development at Hughes. “By contributing to the patent pool we hope to encourage innovation both inside and outside the satellite industry, leveraging DVB-S2X technology to optimize transmissions as bandwidth demand worldwide continues to skyrocket.”

Developed originally by the DVB Project and incorporating a number of key patents from Hughes, DVB-S2X is an extension of the DVB-S2 specification adopted by the European Telecommunications Standardization Institute (“ETSI”), which offers improved performance and features for core applications, including VSATs, Direct to Home (DTH) video and DSNG (Digital Satellite News Gathering). Hughes led the effort to develop DVB-S2X, which is backward compatible to DVB-S2 and improves performance without having to replace it.

Employing DVB-S2X yields higher performance, interoperability and more efficient bandwidth utilization (bits per second per hertz) than previous standards. As a case in point, its integration into the Hughes JUPITER System for the wideband forward channel means operation of a single carrier is closer to the theoretical Shannon curve compared to DVB-S2.
