1) In my opinion, while DV would continue providing dynamic metadata for pre-HDMI 2.1 sets, I think DV will get obsolete with HDMI 2.1 sets. Do you agree?
2) People tend to use the phrase "Dynamic HDR10" on the internet but as far as I understand, its tech specs is not yet finalized as DV. Who knows, once finalized, it will be named HDR+ or HDR10+, which is Samsung's naming in its attempts to bring dynamic metadata. How ever it would be named, is it going to be finalized with the final version of HDMI 2.1?
3) Let's say it would be named "D-HDR10". Once it is finalized, will the current HDR10 TVs be able to be upgraded to D-HDR10 through a simple firmware update or if it will require a hardware upgrade? In this regard the last paragraph in the below link has confused me:
At present Samsung was merely demonstrating that dynamic metadata can be added to HDR 10 and that their TVs are capable of supporting the technology.
, which, to me, implies that this can be made through firmware update;
[I]They still need to build industry support and to deliver dynamic metadata over HDMI will require HDMI 2.1, the final version of which was announced at CES.[I], which, to me, implies that while Samsung seems to be the major player in developing D-HDR10, it will be adopted in a standard form and be available to all manufacturers that use HDMI 2.1.
Or is it going to be up to the discretion of the manufacturers? E.g., perhaps they may lead us to the way of buying a new set despite upgrading via firmware update be possible.
4) HLG could be upgradable, so logically I cannot think of any reason that this would not be possible for D-HDR10. Do you agree?
1. Dolby Vision will continue to be the most premium type of HDR, even in the HDMI 2.1 era, it's popularity is likely to continue to snowball. It's quality is set to remain unrivaled for years to come.
2. There are 4 distinct types of HDR-10 with dynamic metadata. Dolby, Technicolor, Philips, and Samsung all have unique HDR-10 formats, all which use dynamic metadata. Samsung and 20th Century Fox worked together to create their format, 'HDR10+'. 'HDR+' on the other hand, is Samsung's name for SDR to HDR conversion in their tv sets. Samsung and Fox's ST 2094-40 aka 'HDR-10+' is the only new open source, royalty free HDR format, so it's the only true successor to basic HDR-10 with static metadata, it should soon become an industry-wide standard. The format is launching this summer on Amazon, then Netflix and others. Samsung expects their format to become ubiquitous. They expect other tv manufacturers to embrace their new format, and it's also expected that the BDA will soon update the UHD Blu-ray spec to allow for Samsung/Fox's format to become a required part of the BDA spec. After the spec is officially updated by the BDA, and once it is then implemented, it will bring dynamic metadata HDR to all new disks, while still remaining backwards compatible with static HDR-10 and older HDR tvs. I fully expect this to happen, as it's royalty free. It's coming out this summer, so it's 'being finalized' before HDMI 2.1, yet only on 2016-2017 Samsung tvs so far. Those Samsung tvs can internally decode HDR-10+ on the tv's internal streaming apps, but not through HDMI, so you'll need a 2018 model tv or newer, if you want HDR-10+ via UHD Blu-Ray or set top box. Other manufacturers will likely announce support at CES, along with "FreeSync 2" support on some models.
3. The name of Samsung's forthcoming opensource HDR standard has already been settled, it's HDR-10+. Samsung 2016-2017 models will get a firmware update. Do not expect a firmware update for non-Samsung model tvs either. It's going to be a big feature of HDMI 2.1. HDMI 2.1 is going to require a hardware upgrade.
Samsung is not 'the major player' in HDR. The technology was largely invented by Dolby, they made some technology opensource, that allowed for tv companies to embrace the technology, 'HDR-10', they kept some premium features for their premium format and they charge royalty fees to manufacturers for that premium format, Dolby Vision. Samsung and Fox Studios wanted an opensource HDR format with dynamic metadata that could replace HDR-10 moving forward, yet remain backwards compatible. They used Dolby's technology to build upon. Technicolor has a dynamic metadata HDR format too, as does Philips. Philips and Technicolor merged HDR technology, they already have at least one format that is on the UHD Blu-Ray spec from BDA, according to a BDA spokesperson in 2015, both Philips and Technicolor HDR are optional on the BDA spec already. Technicolor's formats have not been officially publicly acknowledged very much, but they do exist.
In the future, expect many UHD Blu-Ray disks to have Dolby Vision, expect many to carry Technicolor's formats, and expect all to carry Samsung's format as a baseline. Samsung and Fox have developed a 'vanilla', 'scene based' HDR format. Philips and Technicolor formats feature unique superior technologies, as does Dolby Vision. So we'll continue to have more premium HDR formats, which charge manufacturers fees, right alongside Samsung's new opensource format. Expect Samsung to continue to blow off all premium HDR formats in their tv sets, but expect Sony, LG, and others to have full support for all forthcoming HDR formats. If Sony will pay for DV, they'll pay for Technicolor's stuff too, they may wait until the format is flourishing with content, but they'll eventually pay the fees and add the technology.
Some may doubt that there is room for Technicolor to introduce another premium 'HDR content-encoding' format, but that's a myopic understanding. Technicolor does a lot of the HDR grading for films as it is, it's not a huge leap for them to grease the wheels with the studios they already work with. Some studios will inevitably embrace the Technicolor formats, and the future revision of HEVC that supports all dynamic metadata formats is imminent, as is HDMI 2.1. Note that Technicolor's upcoming unique HDR formats for streaming content and UHD BD disks are not to be confused with "Advanced HDR by Technicolor" which is a tv/broadcast technology that works with all the tv specific HDR formats, as a vehicle to allow backwards compatibility with SDR and HDR tv, will be used in ATSC 3.0 broadcasts, and also in future cable, and satellite channels.
