SkyEdge II DVB-S2 ACM Enhancements
Not all DVB-S2 implementations are equal .Gilat’s SkyEdge II is
more efficient than usual competing DVB-S2 ACM schemes. This
is due to the incorporation of the following enhancements :
Support of a wide range of ModCods including 16APSK and
32APSK with predistortion where required
Support for short and normal MPEG transport frames
Efficient packing and Concatenation
Advanced scheduling
Network-wide Frame optimization
