There's this "report" but I should warn you, this guy makes frequent mistakes in all his videos.


I've tried leaving him comments before but I don't think he can read.

Scott, according to the owners thread, the LG UP970 got its firmware update today to enable Dolby Vision from discs.

Dissapointed to hear my brand new $2500 NAD T-187 didn't make the list. When I was at the dealer purchasing this processor, the dealer called his NAD rep on the phone and he indicated that it would be a firmware upgrade 'in the future'. Not sure what to believe. Nothing on NAD?

I have not done a side by side on my LG of DV and HDR10, but just comparing the Netflix DV titles to the HDR titles i've seen on Amazon or UHD 4K discs, DV seems to be worse for me as well. DV titles seem to exhibit more grain and appear too dark in some scenes...but that is just an initial impression.

It is not a typo. Onkyo PR-RZ5100 is correct. This is a pre-amp and not a receiver, and thus should be moved to the pre-amp section on your list.

I too am looking forward to the update, which I have to believe is possible since 'lesser' Onkyo receivers (ending in 20) have Dolby Vision already, and the PR RZ5100 is their flagship high end pre-amp.

Any word on the Panasonic UHD player getting Dolby Vision support? If I had been paying attention, I would have purchased the Oppo player, instead.

I watched Luke Cage on Netflix and it's in Dolby Vision. Even at lower bit rate it's really, really nice looking.

I am looking for 2017 model 49-50 inch Dolby Vision HDR smart TV close to $500, any tips.
TCL make only 55 inch P/damn it they cancelled 50 and 65 series that is too big for the space even though I would have loved bigger
The other option is SUPER LED LG and Vizio M55 E0, what you all say? or shall we wait till Black Friday

I have a Pioneer SC-91 which is not on the list, but do have a DV enabled television and player. What is the most effective way to overcome the AVR issue while still getting the best possible sound?

Use the dual HDMI outs of your player. Video directly to display, audio to AVR.

Same here, first I had heard of this anywhere, and I have been checking pretty steadily everywhere.

Maybe only relayed to customers who email them and not officially announced?

Dolby Vision is HDR. It's technically more advanced/capable than standard HDR10, but real world comparisons are a hit or miss when deciding which one looks better.

Basically, the brighter your TV, the less of a difference it makes.

Much of the advantage DV brings to the table is in standardized tone mapping for low nit devices.

HDMI 2.1/HDR10+ brings that meta data improvement for low nit devices.

Also note that standardized tone mapper might not be best for the display technology, panasonic made a key point about this as being the reason why they adopted HDR10+. Currently dolby doesn't allow panel makers to tweak/alter this tone mapping to best suit their display, using a one size fits all tone mapper maybe isn't the best approach.

I can confirm. I got it on Friday for my Denon AVR-S720W as well. My TV doesn't support HDR/DV, so I can't test it out. Stupid non-HDR/DV 4k TV!

Still would like to see a list of sound bars that pass through Dolby Vision. Or, at least, Atmos sound bars that PT DV.

I was reading this dolby vision white paper, I found it interesting that dolby vision content is still encoded using HEVC 10bit profile(main 10), the extra 2 bits appear to be a post process.

You can't magically produce detail out of nowhere, so to me it looks like currently the extra 2 bits are interpolated/smoothed. Much like YUV 10/12bit dvd players that interpolated at higher bits.

Much of the 12 bit potential of dolby vision can't be leveraged until media is encoded/decoded in HEVC main 12.

In my opinion you have misread the dual-layer Dolby Vision concept.
http://www.google.ch/patents/US20140050271
http://www.etsi.org/deliver/etsi_gs/...01v010101p.pdf
https://www.smpte.org/sites/default/...-Ecosystem.pdf











(Leaving out the SDR base layer,) a Dolby Vision content is encoded in 12-bit PQ.

At the encoder stage level, the Dolby Vision signal is split into a base layer and an enhancement layer:
. Base layer = 10-bit HDR10
. Enhancement layer = 12-bit Dolby Vision – 10-bit HDR10
Dolby Vision base layer and Dolby Vision enhancement layer are encoded by standard 10-bit HEVC encoder.

At the 10-bit decoder stage level, the 12-bit Dolby Vision is recombined.
12-bit Dolby Vision = base layer + enhancement layer (+ metadata)

At the end stage level, the 12-bit Dolby Vision signal is processed by a Dolby Vision Display Management.
The Dolby Vision display manager adapts the Dolby Vision video signal to the target TV.

Universal audio/video receiver (Dolby Atmos, DTS:X, etc.) is achieved.
Universal HDR TV (HDR10, Dolby Vision, HEVC HLG HDR, VP9-HLG / VP9-PQ YouTube HDR, Dynamic HDR) is required.

Push for universal HDR TV!

I think you're referring to dual layer streams, which involves using 2 HEVC encoders/decoders. I don't know of any SOC outside of the VS10 that can decode 2 4k HEVC streams, nor are the space/bandwidth requirements feasible.

All the dolby vision streaming encodes we have right now are single layer, 1 HEVC main 10 encode/decode with post process upconvert to 12bit.

When HEVC main12 comes of age, dolby will be able to more efficiently encode 12bit into a single layer without resorting to using a very processing/bandwidth wasteful approach of 2 streams.

For instance apple tv is using dolby vision profile 5.

https://www.apple.com/apple-tv-4k/specs/
"HEVC Dolby Vision (Profile 5)/HDR10 (Main 10 profile) up to 2160p"

https://www.dolby.com/us/en/technolo...ormat-v1.1.pdf

Go to section 2.1 Dolby Vision profiles.

Profile 5 is single layer HEVC 10 encode.

Q: How many HDR formats do you ultimately expect to be approved for broad-based use and with which delivery methods?

A: As HDR technology content comes to market, there could be several possible HDR content types available, including Dolby Vision. What’s important to note is that when mastering in Dolby Vision, creatives can master once to the highest quality and can then derive all other industry approved grades from this single distribution master. Therefore, in order to create a simple playback solution, Dolby Vision will support playback from all of these content types, to ensure the best quality experience with Dolby Vision. There is an industry desire for a single-layer HDR solution that works with the existing HEVC Main 10 profile. The new Dolby Vision Single-Layer profile allows for perceived 12-bit fidelity by providing metadata within a 10-bit profile which is used to provide state of the art tone mapping. As a result, Dolby Vision can deliver the best quality compression, quantization and 420 conversion using industry-standard 10-bit HEVC codecs for maximum compatibility. Dolby Vision is an option in Blu-ray offering the highest quality and is being deployed this year via OTT with a full 12-bit backwards compatible dual-layer approach.
So the 12bit is a perceived resolve with metadata and tone mapping in single layer. Interesting...

Once again, in my opinion you are misreading and jumping to the wrong conclusion.

VS10 is not a SoC.

There are several Dolby Vision profiles: 12-bit PQ / 10-bit PQ / single layer / dual layer using 8-bit AVC, 8-bit HEVC or 10-bit HEVC.
Universal HDR-compliant displays
It's up to each "service provider" to decide which profile to use.

For example, the BDA has decided to use the 12-bit PQ dual-layer profile.

"2.2.3.3.5.2 Dolby Vision
The Dolby Vision video stream is composed of a BDMV HDR [aka CTA HDR10] video stream and a Dolby Vision enhancement layer video stream. The enhancement layer is an HEVC video stream with embedded Dolby Vision metadata. The Dolby Vision video signal is characterized by the followings:
• color primaries: BT.2020 with non-constant luminance
• EOTF(Electro-Optical Transfer Function): SMPTE 2084
• Bit depth: 12bit (combination of BDMV HDR video stream and Dolby Vision enhancement layer)
• Enhancement layer video stream: 1920x1080 resolution, same frame rate with the BDMV HDR
video stream, 100Mbps or lower together with the BDMV HDR video stream"
http://www.blu-raydisc.com/Assets/Do...0729_clean.pdf

Universal audio/video receiver (Dolby Atmos, DTS:X, etc.) is achieved.
Universal HDR TV (HDR10, Dolby Vision, HEVC HLG HDR, VP9-HLG / VP9-PQ YouTube HDR, Dynamic HDR) is required.
