Main features
Compared to DVB-S2, efficiency gains up to 51% can be achieved with DVB-S2X.[3]
Amongst improvements are:
- Higher Modulation Schemes (64/128/256APSK)
- Smaller Roll-off factors
- Improved filtering making it possible to have smaller carrier spacing
Use cases
In particular for DTH, a possible use case is the launch of UHDTV-1 (e.g. 4k) television services in Ku-/Ka-band that will adopt HEVC encoding. (ref,p7)
