Is the Sony algorithm you speak of only in displays or is it part of their disc players as well?

doubtful
  • display manufacturers are generally in conflict in this regard
  • they are 'one or the other'
  • business priorities prevail
  • personally, i am with LG on this (no HDR10+ support) as they arguably have a superior approach/solution

LG have been in bed with Technicolour for a while now and the 'dynamic' system in their TVs is based on the 'Advanced HDR' processing tech AFAIK. It's a system that applies an inverse EOTF of whatever the incoming signal may be (HLG, PQ) to decode it into a raw state, analysing the image as it does so, and then rebuilding it for an HDR output best suited to the display.

Does it achieve the same thing as a dynamic metadata system? Yes. Does it have anything to do with actual branded HDR10+ content? No, because you wouldn't need an HDR10+ disc in order to activate this feature, the whole point is that it analyses the signal itself rather than looking at a suite of bespoke metadata.

Here's an example of what a 4,000 nit display on the LEFT can do with an image compared to current tech on the right.
This image is from CES 2018.

are consumer displays really going to get as high as 10,000 nits?

Don’t know if any current tech would hit that high, but it is the top end of the DV maximum mastering range I believe.

With the picture above, 4,000 seems like an admirable goal!

Default displays : 10,000-nits (coming)

yes (i have already seen it; early this year - almost a year ago)

note :: it's not what most everyone expects/thinks (ultimately an enhancement)

to the point :: display technology will get there - a lot sooner than currently expected

Default LG :: Active HDR :: 'it's not an HDR10+ workaround'

Active HDR

  • no :: this is 'untrue'
  • LG Active HDR is not 'fairly' referenced as an 'workaround'
  • LG Active HDR implementation 'predates any announcement of HDR10+ (as also did Sony Active HDR)
  • Active HDR 'is not an 'HDR10+ workaround' it was an earlier 'forward-thinking' solution to the inherent limitations/errors of HDR10 static metadata
  • Active HDR, by 'not using' the HDR10 metadata of respective content, rather an application of display/processor solution, within the display/processor of the display, predating the HDR10+ solution of similarly using computers to do the same (etc), but in contrast, via dynamic metadata, was 'pro-actively first', therefore should not be referenced as an 'workaround' having recognized a problem, solving it (early-on)
  • Active HDR is also an display/processor centric solution to transforming HD/SDR content to display HDR enhancements, on supporting UHD displays - for consistency of viewing
  • LG Active HDR, essentially, was intended that 'all content' be displayed in 'HDR' dynamically (i hesitate to use this 'charged term')

Default Active HDR :: how it does/does not function

update :: actually, i was wrong in this regard as originally posted
  • LG/Sony Active HDR 'do-not create' the dynamic metadata from the static metadata of HDR10
  • LG/Sony Active HDR :: do, reading/referencing the original content information, without reading/referencing the metadata tags, render an similar end-result HDR viewing experience akin to Dolby Vision and the possibility forth-coming HDR10+ solutions that rely on dynamic metadata tags, with their respective display/processor-centric designs

original post - - edited 12/6/18 @ 2am CST

actually, LG Active HDR 'creates' the dynamic metadata from the static metadata of HDR10 'essentially' as does 'any other approach' as Samsung/Sony

yes :: and, importantly, before Samsung (HDR10+)

essentially :: two different approaches to the limitation of HDR10 (make your choice?)

unfair and untrue :: the LG Active HDR (in production displays) 'pre-dates' HDR10+ (announcements) - you actually have it backwards

i disagree :: it is relevant to this thread/topics, unless censorship prevails, or mis-information for that matter

You can't have HDR10+ if the display and/or the player ignore the HDR10+ metadata

Default Active HDR & "metadata" (correction(s) & apology)

Active HDR & "metadata" (correction(s) & apology)
  • first :: my apology for 'mis-using the term metadata' in Active HDR processes/solutions :: i was incorrect (technically)
  • second :: Active HDR 'does not 'create dynamic metadata or process in it's functionality
  • third :: Active HDR is an 'display/processor' solution to the inherent limitations of both HD/SDR & UHD/HDR10, with an intent of consistency of viewing performance with UHD/Dolby Vision - picture quality, that does so 'without either referencing or using metadata', rather working otherwise with the original content

  • yes (now essentially in agreement?) "What you were talking about is internal processing. LG and Sony have their own algorithms to process incoming HDR10 material and dynamically (no though) adjust them."
  • Active HDR and HDR10+ :: essentially, they either in the content/read or within the display itself, offer an 'more accurate' HDR solution
  • so, the end result displayed (differing approaches), is essentially the same (result - as displayed/presented :: beyond that, the hype/PR/politics/information, etc - get 'very involved and convoluted - as i perceive it)
  • to be clear :: while Dolby Vision/HDR10+ embed 'into' the content and decode using metadata, Active HDR, whether LG or Sony displays, simply 'create' similarly in real-time (without using metadata) producing the same resulting picture performance
  • note (further thoughts) :: i think the Active HDR solution(s) in the display/processor to have obvious advantages, as over time the potential for improvements in technology (firmware/processors/displays/etc), refining the picture at almost any point in time :: (HDR10/HDR10+ are both 'embedded/baked in' which limits them to the moment of encoding - permanently, without any possibility of improvement)
  • Dolby Vision is forward-thinking, so it's already future-proofed (to the extent that future-proofed is possible - 2021+?) for the forcible future of content/display performance
  • note :: "dynamically adjust them" is either incorrect or not the best choice of words; is it not? :: they both (approaches/solutions), independently 'process from the non-metadata of both HD/SDR & UHD/HDR10 content to internally, improve/create HDR performance on-the-fly that is more pleasing to viewing than otherwise offered (is this not so?)

original posting :: edited 12/6/18 @ 1am CST


"What you were talking about is internal processing. LG and Sony have their own algorithms to process incoming HDR10 material and dynamically adjust them."

LG/Sony and Samsung HDR10+ (essentially, they're 'all' either in the content/read or within the display itself

regardless, the end result displayed, is essentially the same (beyond that, the hype/PR/politics/etc, get 'very involved and convoluting)

to be clear :: while Dolby Vision/HDR10+ embed 'into' the content and decode, Active HDR, whether LG or Sony displays, simply 'create' similarly in real-time producing the same resulting picture performance

note (further thoughts) :: i think the Active HDR solution in the display/processor to have obvious advantages, as over time the potential for improvements (firmware/processors/displays/etc) refining the picture at almost any point in time (HDR10/HDR10+ are both 'embedded/baked in' which limits them to the moment of encoding)

Dolby Vision is forward thinking, so it's already future-proofed for the forcible future of content/display performance

note :: "dynamically adjust them" is incorrect; is it not? (they both independently 'create dynamic metadata internally, on-the-fly)

Just an FYI.

Mis-information? You just don't know what you are talking about.

HDR10+ is based on metadata put on disc by the STUDIO (Fox, Warner whatever), not created on the fly by the display

It's not the same thing.

good point but in the end it turned out to be a workaround for HDR10+ even though that might not have its intention in the beginning...the LG displays are a rarity in that they really tried to give consumers a lot of very future proof features (Active HDR, Technicolor, HLG etc) instead of just doing what TV manufacturers normally do which is to fix a few bugs but leave the majority of new features and major bug fixes for the following years new model forcing consumers to buy a new TV

the point is that in the end the picture quality of a UHD Blu-ray with native HDR10+ implementation on a Samsung display and LG's Active HDR implementation is going to be prety much indistinguishable to the end viewer...that's all that really matters

Let me put it this way....

If HDR10+ is useless because of "Active HDR" then the same logic applies to Dolby Vision as used by Warner and Sony (metadata only layer)...

I'm OK with that logic, by the way....
