You then have to send Absolute Mode metadata to kick into DV, and can then switch between that and Relative for calibration purposes and that's it (at least in CalMAN Home).
One would assume that this is all TV-Led DV.
Well yes but not really what I meant at all.
I guess the only way to compare Player vs TV Led DV is with a device that can force either with a specific option, such as a dedicated TPG (???) or a device with the option toggle (OPPO 203).
All I meant, was routing the Apple box through the HDFury, but manipulating the EDID with the tick boxes in the UI. The sort of thing that Projector owners do to workaround EDID issues.
If the HDFury had the two tick boxes which it doesn't have, then you could change the TV's capabilities as read by the Apple box, to force the Apple box to send either:
* TV-led (RGB 8bit with the 1 or 2 DV 10 bit streams tunneled inside),
* Player-led (decoded by the Apple box into a single 12 bit DV stream)
...at will, by ticking different boxes.
Currently, LG 2018-2020 (at least) TVs support both.
Older LG TVs (I don't know which years) support only TV-led.
Sony TVs support only Player-led
I was only ever talking about changing the EDID presented to the source device using the HDFury. Nothing about Infoframes, or AVI frames, or metadata, at all.
. All that stuff is untouched all the way from Apple box to TV (through HDFury). It's only changing the EDID of the TV
I still don't get this perceptual metadata though. I was always under the assumption that HDR (including DV) was Absolute? I've tried a quick search online a couple times but found nothing.
Agree, the very term "perceptual metadata" is alien to me
. I know that the LG has its special "I'm in Dolby Vision mode but not with PQ" mode that is only possible during Calibration, but I always understood that to be controlled by Calman commands, or special "secret sauce" in the patterns - but not the "metadata" as you and I understand it - which only really specifies MaxCLL, MaxFLL etc.
But I wasn't talking about anything like that at all! I was only suggesting a way to make the Apple box choose either TV-led and Player-led modes at will, even if you have a TV which supports both types which would normally default to only one of those. This would allow you to could do an A/B comparison on your TV of some Apple-sourced Dolby Vision movies. I should have been a bit clearer earlier, sorry
