The successor to the DVB-S2 standard is a combination of
innovative technologies did improve overall efficiency over
satellite links.
The technologies Involved in DVB-S2X are:
• Low roll off, smaller carrier spacing and advanced filter
technologies
• MODCOD and FEC upgrades (more granularity,
adding 64, 128 and 256APSK, Improving FECs &
MODCODs and Differentiating linear & non-linear
MODCODs)
• Wideband implementation.
• Very Low SNR MODCODs to support mobile
(land, sea, air) applications
• Bonding of TV streams
• Additional standard scrambling sequences
Don't forget that it is an Arm processor, current addons and plugins will have to be rewritten for the receiver.
