Once you have detected the black bars what you would ideally do is use that information to send RS232 or perhaps IP commands to control an electrics masking projector screen, to move the masks to correct position, and perhaps also to move an anamorphic lens infront of the projector lens and change the projector lens memories. Should also have capability to query bar information for custom applications.
The aspect ratio detection is available in the Lumagen Pro, but all the control aspects have to be implemented elsewhere. I have a Lumagen Pro and am using this function, I have a Raspberry PI hooked up to serial port on Lumagen to parse the information and set up my system. Would be nice to have other options.
There is at least one member on this forum who might have another use for this; @Dj Dee
has a full-shut-off shutter he uses to give full fade to black for black screens during projection. He has some quite complicated electronics to detect the black screen and then move his shutter in place.
As an aside, I was under the impression that DIVA was just MAESTRO without HDBT... but it seems like there is some architectural difference internally which makes some things possible on DIVA that can't be done on MAESTRO?
Yes should be possible by making changes in RS232 macro and add black bar detection over there, you still need to provide the rules, ex: is one RS232 enough or you need multiple RS232 commands sent in a row. you need to be very specific in description if you want us to add such feature.
Maestro is HDBT oriented, Diva doesn't have HDBT, but have HDR>SDR converter instead that Maestro doesn't have.

I’ll warn you in advance this is a very specific application.
I’m looking to possibly employ the use of a MiniDSP Nano Dirac Live processing unit. I’m also running an older Pre Pro that doesn’t accept HDCP2.2. The Nano needs 7.1 PCM and it needs a video signal to work, no greater then 1080 and 1.4 HDCP
So looking for this or another device, that is going to take the great output from my Panasonic UB820, my Apple TV 4K and my Roku Deluxe, switch between the 3 (could be limited to two if need be), separate the HDCP2.2 18Gbps 4K HDR 60fps 4:4:4 video of the selected input and send it via one output directly to my JVC RS400, and then separate the 7.1 PCM audio stream and a combined HD1.4a Hd video signal (MiniDSP needs this in the stream again to process the audio) and send it to the MiniDSP and then to my Non HDCP2.2 PrePro for audio assignment to my 7.1 XLR outputs.
What this does for me is gives me switching for 2-3 4K HDCP devices on my Jurassic pre-pro, gives me 7.1 Dirac Live room correction technology for those sources, and allows me to keep my current PrePro.
If you’re wondering I’ve decided to stick to 7.1 for a while due to somewhat low ceilings and sound dampening acoustic tiles as the ceiling (which would null any reflections of Atmos upfiring speakers). Not going to chase that format yet given those limitations.
Any added extra bonuses I get for the JVC video is a plus. Maybe audio or video felt to time align the signals may be required. However with the Panasonic UB820 tone mapping and SDR output it’s doing pretty fine on its own.
Thanks for the read on this.

That looks like basic 4K HDR passthru + downscaled signal or forwarding of full audio via self generated stream for HDMI/HDCP 1.x equipment so no problem, works out of the box.

It would be so much easier with all cables on one side.
I struggle already with Integral2.
You prolly mean why "don't you have" ... ?
If yes, then answer is easy, the product would look weird if it had all connectors on one side, basically twice as large, half less long, kind of soundbar style.
The device is not made to be rack mounted, it is made to provide real time info via OLED/OSD, on the fly configuration thru push buttons and OLED menu with inputs in front of you, typical desk usage.
