      Possibly a silly question but is it known whether this will just be available on apps or through HDMI as well?

      I'd be very surprised if it wasn't via HDMI. Dolby Vision UHD Blu-rays and compatible players are popular at the high-end, where the Sony A1 is aimed.

      Finally! I'll also add a silly question. Is Dolby Vision only for video content or can it also be used for gaming?

      I guess cut-scenes in games could use it, but I'm not sure the automated generation of DV Metadata is something people are using for gaming. DV is more based around sending metadata on a scene-by-scene level allowing the display to base display decisions with more information about the way the source 'should look'.

      I think - though can't be absolutely certain - that some of the metadata requires the entire scene to be known about before the metadata can be derived - which is tricky for live gameplay (and is also why DV is a terrible fit for live TV production)

      Yep. There have been some tests for live DV productions (this year's French Open tennis, I think?) and Dolby are still trying to shill it to broadcasters now that the metadata has been standardised somewhat as SMPTE 2094-10 but HLG will take care of broadcast HDR, the BBC have created a set of LUTs which can integrate even SDR cameras into the HLG workflow (but I'm sure you know that Stephen, this is more for us mere mortals! :D) and a relative luminance system just makes more sense.

      And even on a pre-recorded TV broadcast the dynamic metadata of DV gets a bit tricker to manage when all those 'coming up next' boxouts are overlaid because it's jumbling different sources together.

      Yep - Dolby are still trying to push it, but I really don’t think there is any appetite for it. HLG was designed by broadcasters, for broadcasters, and makes a whole lot more sense for live and as-live multi-camera production.

      Once you end up with multiple DV-metadata sources on-screen at once (say wiping from a server slowmo replay to a live camera, or split screening a commentator in a box with a live shot) things get complex very quickly. Then what happens when you run an end credit squeeze? Heck - what happens when you just mix between two cameras ?

      HLG works very effectively as a live production format - I don’t see a rush for Dolby Vision for live. DV MAY get some traction as a post format for multicamera productions - but that’s a post thing...

      HDR10 with fixed metadata chosen in advance has been used for some US HDR TV production (2016 Rio Olympic Opening Ceremony) but it offers no major benefits over HLG AIUI, introduces some issues, and doesn’t offer any of the benefits of DV either.

      If Sky or BT start doing UHD HDR production, I’d be surprised if it weren’t HLG.

      The BBC have a set of LUTs for conversion between HLG and HDR10 PQ at different HDR10 nit levels (PQ bites you that way) as well as 709<->2020 SDR stuff.

      The update is available in the US now and apparently no HDMI support, only internal apps :(

      Do you have any sources for that information as it seems very unlikely to me.
      Only today HDTV Tests put a video on YouTube showing Sony’s New DV enabled X700 player at CES running DV on a ZD9. How would that be possible if the update doesn’t include HDMI support?

      There's various people on the American forum complaining about it plus it is mentioned in the Sony OLED owners' thread on here.

      Hopefully it's something that will be resolved soon.

      Let’s hope it’s a bug, otherwise DV support will be almost pointless.

      From the US website it does look like HDMI support was or is proposed:

      [​IMG]

      But one user here has been told emphatically by Sony support that DV is for Apps only, but could be a missinformed sony representative:

      If this proves to be the case, I can see (in the USA at least) a class-action lawsuit against Sony for misleading buyers.

      Wow if this is true and it remains via app only with no HDMI I will be devastated and feel very mislead by Sony. Full DV support was a critical reason I picked the XE93 model over LG. It was my first piece in a full Home Theatre revamp :mad:

      I for one would have been quite happy with it only working in Netflix in the short term whilst they sorted the problems out as I'm waiting on a marantz update anyhow.

      My gutting feeling says that with this problem it will be many months to any EU update happens now :(
