DD is not a core component of DTHD. DD is a separate track and is a BD requirement.If the 7.1 is a 'core' component in a Dolby Atmos file, is not the 5.1 also a core, for legacy purposes? That is, for hardware with pre-Atmos Dolby decoders?
We can extract and analyse cores without Atmos enabled using tools like MakeMKV. Would it be right to say that the only way to objectively analyse Dolby Atmos output in 7.1 (or 5.1?) with Atmos enabled (i.e., with extra channels mixed in to it) would be to record the analog output? Or is there any software yet that does Atmos decoding and can output in multiple channel formats? Because it looks like the comparisons people are interested in include
x.1 core vs x.1 Atmos-enabled
DD vs DTS
Could the DTS cores look so similar yet distinct from DD due to having had Atmos channels mixed in to the DD core before DTS encoding? IOW, the DD 5,1 core + Atmos channels folded in = DTS 5.1 ? This might make sense because you could not get the *Atmos-enabled* DD 5.1/7.1 experience from DTS without doing that .
It would require Atmos-savvy software tools to demonstrate, though.
DD does not support Atmos.
DD+ and DTHD support Atmos.
