DVB-S2X is a digital satellite television broadcast standard.
DVB-S2X is an extension of DVB-S2 satellite digital broadcasting standard. It was standardized by DVB Project in March 2014 as an optional extension of DVB-S2 standard. It became an ETSI standard.
Main features
DVB-S2X increased efficiency up to 51% over DVB-S2.
Improvements include:
Higher order modulation schemes (64/128/256APSK)
Smaller roll-off factors of 5%, 10% and 15%
Improved filtering enabling smaller carrier spacing
Channel bonding in order to combine several carriers, increasing efficiency in 'Direct-To-Home' (DTH) applications
Channel bonding helps, particularly for UHDTV services. Statistical multiplexing is often used to allow more television services to fit into a single satellite channel. Statistical multiplexing works best when many television channels can share bandwidth. With UHDTV services, it may be possible to fit only 3 services in a single satellite channel, which reduces the effectiveness of statistical multiplexing. Bonding channels increases the number UHDTV services within the bonded channel, allowing statistical multiplexing to work more efficiently.
Because of a lack of backwards compatibility with DVB-S2 decoders, Belgian company Newtec developed the 'DVB-S2plus/Extensions' technology.
Use cases
A possible use case is the launch of UHDTV-1 (e.g., 4k) television services in Ku-/Ka-band with HEVC encoding.

DVB-S2X (Second Generation Satellite Extensions)
The S2X system offers the ability to operate with very-low carrier-to-noise and carrier-to-interference ratios (SNR down to -10 dB), to serve markets such as airborne (business jets), maritime, civil aviation internet access, VSAT terminals at higher frequency ranges or in tropical zones, small portable terminals for journalists and other ...
What’s the Difference Between DVB-S2 and DVB-S2X Standards?
Aug 3, 2018 · DVB-S2X supports very low C/N (down to −10 dB) for mobile applications like marine, aerospace, trains, etc. Like DVB-S2, DVB-S2X uses LDPC FEC schemes and BCH FEC as an outer code. DVB-S2X incorporates additional features and technologies, such as: Shown is a comparison of DVB model performance.
DVB-S2X (Second Generation Satellite Extensions) - Guidelines
The present document gives an overview of the technical and operational issues relevant to the system specified in ETSI EN 302 307-2 [i.2], and is intended to provide guidance to broadcasters and operators considering the adoption of DVB-S2X.
Difference between DVB-S2 and DVB-S2X | DVB-S2 vs DVB-S2X
DVB-S2X is the extension of DVB-S2 standard. It adds many new features to DVB-S2 standard. The ETSI EN 302 307-2 (part-2) document defines specifications of DVB-S2X. DVB-S2X uses LDPC and BCH as inner and outer code FEC techniques similar to DVB-S2. The major features of DVB-S2X are as follows.
DVB-S2X Technology - Rohde & Schwarz
DVB-S2X enables a higher performance and extends the functionality of the DVB-S2 standards and its applications such as direct-to-home (DTH), DSNG and professional VSAT applications and related services.
