I wonder why EAC3-JOC isn’t like DTS-HD where if a client can’t play HD or DTS:X but can play basic DTS it just ignores the extra audio data and plays DTS Core. Why can’t EAC3-JOC just drop the Atmos metadata and play simple EAC3 on devices that don’t support Atmos? Then there is no need to transcode anything. DTS has done this for years so it cant be difficult. Dolby seem a bit backwards here. True HD should have had an AC3 core to fall back on too and doesn’t.
