Satellite communication is a multi-billion market, with dozens of satellites being launched each year, providing terabytes of capacity worldwide. Despite the growth of alternative and competing terrestrial and wireless solutions, satellite continues being a must-have for areas not or just barely connected and shows its full economic potential in supporting one-to-many connectivity.
DVB-S2 is the de-facto standard being used in direct-to-home (DTH) satellite TV distribution. DVB-S2 is also widely adopted in satellite broadband (»satellite internet«) for the user downlink and in many interactive or professional peer-to-peer networks. Compared to DVB-S2 developed and specified in the early 2000s, DVB-S2X is a state-of-the-art, backwards-compatible extension and superset, providing higher spectral efficiencies and new features to enable or promote new applications.
Fraunhofer IIS was actively involved in the development, specification and validation of DVB-S2X. The subsequent section provides further insight into
- how DVB-S2X differs from and extends DVB-S2;
- key additional features in DVB-S2X and their implication on performance and for new applications; and
- DVB-S2X technology and IP available at Fraunhofer IIS for specific markets.
