This is not a matrix-encoded channel, but a spatially-encoded digital channel. Atmos in home theaters can support 24.1.10 channel, but it is not an object-based real-time rendering. Filmmakers need to remix and render the TrueHD and Dolby Digital Plus soundtracks with Dolby Media Producer. TrueHD is base with the help of MLP, so it would be not far fetched if Atmos also depends on same codecs with Meridian techteams help.
Well I am definitely missing something here then. Why all the hype for home Atmos? Sounds like a big let down. Isn't spatial encoding kind of like Ambisonics? If so it's hardly revolutionary. Sounds like a damp squib to me. Not sure I would invest too much in it based on that. Certainly not enough to jump to 861v9 territory just to get it.

Cheers,
