Ok, good point.

What about like this then:


Where "nPSK" represents whatever n=B/Q/8/16A/32A PSK, DELSYS=DSS/S/S2 
indicates that it is a DSS/DVB-S/DVB-S2 system type. Thereby all system specifics 
will be followed by eg: S2:*, thereby better readability.

Why nPSK should come ahead delivery system:

* delivery system is a subset of the modulation
* not all 8PSK modulation is DVB-S2.

Comments ?
