The "+M" version added several new features, such as the ability to use "DVB-S2" burst in the uplink channel back to the satellite.

In contrast to other satellite communications systems, DVB-RCS was created in a open environment where any DVB member can participate. DVB membership is open to all companies willing to subscribe. The work group called "DVB TM-RCS" is currently pursuing other technical solutions for the approved commercial system.
In 2009 technical work started for a new version of DVB-RCS called "DVB-RCS NG" (Next Generation). In this more powerful version of the standard "RCS2" there will be support for Higher Layers for Satellite (HLS)... Read More
