but for sports regarding anything other than a snail race, it will unequivocally present a visual quality improvement. And I for one, am a sportsman and a sports watcher . Tob, good luck Arsenal this weekend!

Alas, it will need to wait until tomorrow or maybe this weekend as I’d like to hunt down an illustrative YouTube from earlier this year to make the point, if I can find it.

So, PQ10 and HLG10 are new HDR formats.


Hopefully HLG10 are exactly similar to HEVC HLG HDR of the Japanese NTT (and others).
In particular, hopefully, there is only one HLG uncompressed video.

HLG10 content >> broadcast network / Internet >> HLG10 compliant streaming media player / set-top box > HLG uncompressed video >> HLG10 compliant TV

VP9-HLG content stored on YouTube cloud >> Internet >> VP9-HLG compliant streaming media player / set-top box > HLG uncompressed video >> VP9-HLG compliant TV

NTT Hikari TV 4K IP channel broadcast in HEVC HLG HDR >> IP network >> VP9-HLG compliant streaming media player / set-top box > HLG uncompressed video >> HEVC HLG HDR compliant TV



PQ10 = HDR10 without HDR10 metadata

PQ10 content >> broadcast network >> PQ10 compliant TV

PQ10 content >> broadcast network / Internet >> PQ10 compliant streaming media player / set-top box > Ultra HD Forum PQ10 uncompressed video >> PQ10 compliant TV


HDR10 content >> Internet >> HDR10 compliant streaming media player / set-top box > CTA HDR10 uncompressed video >> HDR10 compliant TV

VP9-PQ content stored on YouTube cloud >> Internet >> VP9-PQ compliant streaming media player / set-top box > CTA HDR10 uncompressed video >> HDR10 compliant TV

I am wondering if the Ultra HD Forum PQ10 uncompressed video can tolerate / include HDR10 metadata with blank / default value (i.e. PQ10 uncompressed video = CTA HDR10 uncompressed video) so that there is no need to use a special PQ10 streaming media player / set-top box for outputting CTA HDR10 uncompressed video.

PQ10 content >> broadcast system / Internet >> PQ10 compliant streaming media player / set-top box > CTA HDR10 uncompressed video >> HDR10 compliant TV

More signs 4k is just the stepping stone to 8k quality.

Apparently, a PQ10 compliant set-top box / streaming media player can send default value HDR10 metadata to a PQ10 compliant TV or a legacy HDR10 compliant TV.

PQ10 content >> broadcast system / Internet >> PQ10 compliant set-top box / streaming media player > "CTA HDR10 uncompressed video" >> legacy HDR10 compliant TV

The static metadata (SMPTE ST 2086) is optional for HDMI 2.0a so there is no need to send fake metadata. That is why he keeps saying that broadcasters don't want to use static metadata since he thinks you are asking for an explanation.

With Amazon’s The Grand Tour, I wonder how that offering will factor into all the consumer Dolby Vision versus HDR10 online 'debates'.

P.S.
In the 3rd paragraph of the farmgroup spiel, it should actually read Arri Amira as noted by Dan at the last IBC Neat little camera.

Thank you, Richard!


As metadata is not mentioned in the DECE HDR10 media profile, the HDR10 metadata could be also optional in HDR10 HEVC coding.
Then PQ10 is similar to HDR10, and a legacy HDR10 compliant TV could be compatible with PQ10.

PQ10 = HDR10 without HDR10 metadata

PQ10 content >> MPEG-2 TS broadcast network ("DVB-T2", "RTP/UDP/IP" …) >> PQ10 compliant TV
PQ10 content >> MPEG-2 TS broadcast network ("DVB-T2", "RTP/UDP/IP" …) >> legacy HDR10 compliant TV

PQ10 content >> MPEG-2 TS broadcast network >> PQ10 compliant streaming media player / set-top box > CTA HDR10 uncompressed video >> PQ10 compliant TV
PQ10 content >> MPEG-2 TS broadcast network >> PQ10 compliant streaming media player / set-top box > CTA HDR10 uncompressed video >> legacy HDR10 compliant TV

However, there could be some interoperability issues between HDR HFR PQ10 content and legacy HDR10 compliant TV due to different HEVC levels:
. HEVC Main 10 Profile at Level 5.1 is used for legacy DECE HDR10 compliant TV and for HDR PQ10 compliant TV
. HEVC Main 10 Profile at Level 5.2 is used for HDR HFR PQ10 compliant TV.

For those too shy to contact him, the answer is no, you do not necessarily need to grade your content on a Dolby Pulsar in order to meet their HDR deliverables requirements.

Also, a little advice with regards to achieving the best outcome in terms of picture quality (and avoid the pitfall of the inherent nature of MaxFALL and ABL with reference monitors vs. consumer TVs in a grading suite) - - While grading always keep your eyes on the reference monitor (BVM-X300), not the client monitor, as the former has a helpful Over Range indicator which lights up to alert you when the brightness level is exceeded and the ABL kicks in.....otherwise it's like swimming upstream against the current.

I’m not really entirely sure what it is with cars (I’m more of a motorcycle guy, occasionally some heavy duty adventure touring - https://forum.blu-ray.com/showthread...1#post12110781 ,
but mostly svelte off road riding/racing - https://forum.blu-ray.com/showthread...n#post10135188 , anyway, whaz up with cars and HDR….in any country?….

but I do think The Grand Tour just woke up the advertising guys in the auto industry. And I know of at least one cinematographer, namely Bill B. at the podium last Thursday night -



who is probably smiling at the thought of the potential HDR business from those well-heeled auto clients….http://www.wfb4.com/bill-bennett-asc-automotive--c1kc4. Bill, you just might have to expand the curriculum (HDR) of those fine ASC Master Classes at which you teach.
