DVB-S2X is an extension of DVB-S2 satellite digital broadcasting standard.

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.[1] It will also become an ETSI standard.[2]

Main features[edit]

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

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)

Use cases[edit]

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)
