DVB-S2X is a digital satellite television broadcast standard. It has been standardised by DVB Project in March 2014 as an optional extension of DVB-S2 standard. It will also become an ETSI standard.
Compared to DVB-S2, efficiency gains up to 51% can be achieved with DVB-S2X.
Amongst improvements are:
- Higher Modulation Schemes (64/128/256APSK)
- Smaller Roll-off factors
- Improved filtering making it possible to have smaller carrier spacing
Due to a lack of downward compatibility with existing DVB-S2 decoders, Belgian(?) company Newtec has developed the 'DVB-S2plus/Extensions' technology, which tries to reconcile the benefits of the DVB-S2X with compatibility to existing systems. (http://www.newtec.eu)
