Stream can be anything :) But for DVB standards this anyway DVBS transport 
stream 188 byte. Most media-bridges can handle only this stream. Specific 
generic-continous DVB-S2/T2/C2 streams require extended bus for passing 
frame-based stream, so this out of V4L DVB.

Now MIS used often for distribution multiple digital terrestial muxes over one 
satellite carrier (implemented in my patch, now i make patches for VDR and 
TVHeadend for MIS). DVB-T2 PLP is same, but i not see any real-life 
implementation (have some tda18712/cxd2820r-based hardware and 
T2/256QAM-in-air, but only one PLP). Don't know anything about ISDB :)
