Ok, had a bit of time to read the (somewhat limited) technical
document and it appears that it is basically component audio +
background soundscapes (aka "beds"), with final render done in the
theatre by panning the individual audio objects according to the sound
trajectories defined in the mixing stage. The beds are channel based,
i.e. (I guess) pretty well standard panned to speakers 5.1/7.1/9.1....
arrays. There's no info about how panning is done in cinema renderer
but maybe VBAP? Anyone have any more detailed technical info?

And probably still more...
Seems that there is a common trend in cinema audio.
Anyway, as "everybody knows", "surround is dead". ("Case closed.")
At least this is the impression if any young person is following the
teachings of this list. :-[
(Or: surround is < maybe > not dead if you cram 3 matrixed channels into
2 channels of Apple- compressed AAC iTunes files - which is actually a
worse solution than we already had in the 80s. :-D )
Dolby's "beds" seem to be 5.1/7.1 mixes, or submixes. The system seems
to be hybrid, and definitively backward-compatible to 5.1 and 7.1.
(Makes a lot of sense, from a Dolby perspective.)
