Thx again for all help guys.
Can DD+ be passed over optical?
Can DD+ be passed over optical?
Plays as DV on my LG Oled TV Prime app.
Which would you recommend around £200?Why? There are better players.
So you can’t turn the CEC control ‘off’ on the player?
I have an old Sony Blu-ray player at present, but want to replace it now I have an LG 4K tv. Nothing fancy, just a £350 43” model.
The Sony BD is terrible, very slow to read discs, horrible PlayStation style interface and now it has stopped sending Dolby Digital to my Onkyo. I vowed to never buy another Sony product again!
Is anyone using an xbox x for playing movies if so could you give a review on how it plays please thinking about picking one up ive got a ps4 pro but im thinking about getting an xbox x for the 4 k player many thanks
Denon and Marantz AVR's (maybe others) both show DV as 8 bit from Sony and Panasonic players too. It's not an issue with the players, like your LG they are outputting DV so don't worry about it.
If you want to check yourself connect player direct to TV and play a DV disc, then do same via your receiver. When I did this the picture is exactly the same.
Many thanks for this link, great info also on how the DV signal is passed along the HDMI chainMarantz SR7010. Shows 8 bit RGB for Sony X700 and Panasonic UB820.
Don't know if Denon/Marantz are just incorrectly reporting the info or if what is described below holds true for UHD discs. As noted at the end AVRs can report DV as either 8 bit RGB or YCbCr 4:2:2 12 bits. Both are stated to be correct
Dolby Vision RGB Tunneling
The method Dolby Vision (DV) uses to transport the signal over HDMI is referred to as “RGB Tunneling”. The 12-bit ICtCp DV signal + Metadata is encapsulated inside the regular RGB 8-bit video signal. The DV “tunneling” carries 12-bit YCbCr 4:2:2 data in an RGB 4:4:4 8-bit transport. This is possible because both signal formats have the same 8.9 Gbps data rate requirements.

DV requires dynamic luminance data which cannot be explicitly carried in an HDMI 2.0 (18 Gbps max) data stream, so it is designed to transport over HDMI 1.4 (8.9 Gbps max); at least up to 4K@30. DV base content and DV luminance (meta) data is encapsulated in an HDMI 1.4 compatible (except HDCP 2.2) RGB 4:4:4 8-bit video stream. That's why Dolby claims that DV can be sent via HDMI v 1.4, but in reality, HDMI v2.0 is needed due to the HDCP v2.2 encryption.
The DV metadata is encoded into the least significant bits of the chroma channels. Upon the HDMI EDID exchange (handshake), the sink (AVR, Display, or HDMI switch) signals the source that it supports Dolby Vision "tunneling". The source then signals the sink that it's transmitting Dolby Vision through an AVI Infoframe, which therefore triggers the Dolby Vision mode in the sink. The display DV engine extracts the components and produces a tone mapped image.
As a result, video pass-through components must be DV 'aware' to not alter the signal, which is in effect 'hidden' inside the 8 bit RGB 'container'.
AVR’s may report DV signals in one of two ways, but both are correct:
Resolution: 4k:24Hz ->4k:24Hz
HDR: Dolby Vision
Color Space: RGB 4:4:4 -> RGB 4:4:4 -OR- YCbCr 4:2:2 -> YCbCr 4:2:2
Color Depth: 8 bits -> 8 bits -OR- 12 bits -> 12 bits

Good morning!
I have a quick question regarding Dolby Vision and Sony Bravia TV's. The ubk90 and the Sony Bravia's have different versions of Dolby Vision, one is low latency, the other is not. Since there is no option on the ubk90 to turn off Dolby Vision and use HDR10 instead, what exactly happens?
Does anybody have any experience in this regard? I have found this player on sale for a reasonable price, I hear very good things, but this DV issue is holding me back. I don't care about DV one way or the other, but I remember reading one account somewhere that the picture get's messed up when the player attempts DV on a Bravia.
Any insight would be HUGELY appreciated.
Thanks!
Where?
Just avoid, get a player which support Sony's implementation of DV instead. Sony X700 or Panasonic UB820 and a few others.
My X700 is quiet. Check whether where you buy from would allow you to return if noisy.X700 is an option but i'm concerned about the loud noise it makes according to many people.
