What are the benifits of new DVB-S2 Extensions?
Millette Manalo-Burgos of APB has interviewed Peter Siebert, Executive Director of DVB Project, and Steven Soenens, Vice-President Product Management of Newtec, for their January 2014 issue to get detailed answeres on this question.
In its quest to achive more efficiency on the use of satellite communications technology, industry players have acknowledged the need for a "successor" to the current DVB-S2 standard. The consensus is that having such "extended" technology would help accommodate the ever-increasing interoperability and growth in the satellite communications market.
"Satellite operators, broadcasters and manufactures require a technical standard for higher efficiencies without a fundamental change to the complexity and structure of DVB-S2," Peter Siebert, executive director of the DVB Project, tells APB.

These are the key quotes in APB's article:
Peter Siebert, Executive Director of DVB Project: "The forthcoming DVB-S2 Extensions will provide performance improvements of 30%-40% for the SNR range, usual for [professional] applications. In addition, the S2 Extensions will also support low SNR reception situations, which are typical for mobile or disaster relief applications."
Steven Soenens, Vice-President Product Management of Newtec: "We need the S2 Extensions in Asia to provide higher efficiency, more bits per Hertz and more content at lower Opex. In Asia, there is limited capacity on satellite, particularly in the C-Band, and having this new standard will be essential for applications including VSAT broadband, IP trunking and primary distribution."
S2 Extensions Offer Improvements
Additionally do not miss the list showing the improvements S2 Extensions offer compared with DVB-S2. Below you see 2 of the listed 7 improvements:
Improvement 1 of 7: Lower Roll-Offs (RO) - Reducing RO to 5%, 10% and 15% resuts in a direct gain in bandwidth.
Improvement 2 of 7: Advanced Filtering for improved Carrier Spacing - This innovation provides advanced suppression of side lobes such that carrier can be put more closley to each other on the transponder.
