Yay! Now to wait for the new receivers to come out

Thats laughable. Can any receiver handle the following.

• 4K@50/60, (2160p), which is 4 times the clarity of 1080p/60 video resolution
• Up to 32 audio channels for a multi-dimensional immersive audio experience
• Up to 1536kHz audio sample frequency for the highest audio fidelity
• Simultaneous delivery of dual video streams to multiple users on the same screen
• Simultaneous delivery of multi-stream audio to multiple users (up to 4)
• Support for the wide angle theatrical 21:9 video aspect ratio
• Dynamic synchronization of video and audio streams
• CEC extensions provides expanded command and control of consumer electronics devices through a single control point

So whats the point of 32 audio channels? How about 1536kHz audio sample frequency? Then you have 4K@50/60 which requires double the stream bandwidth, or twice the storage or CPU power? If one would take a step back and look at this from a commercial theater side, yes this simplifies cabling just like HDMI got rid of all those cables in a home theater.

But the big question is does HDMI 2.0 spec being released buy the consumer anything at this time or a year from now?

lol, isn't that why he said "Now to wait for the new receivers to come out"? Because none currently do?

I was agreeing with the poster, the situation is laughable, but also quite sad. Here we have the HDMI.org trying their darnest to keep ahead of technology, well congratulations they succeeded.

What's the point of 32 channel audio? Have you heard of Dolby Atmos or Auro3D 11.1? By upgrading the bandwidth, the possibility of bringing object placement surround is now a lot higher. Previously,we were only limited to 8 channels of audio. Anything more, and we have to settle for a matrix surround format. (Eg. DTS Neo:X)

The upgraded video bandwidth means that 2K/1080p HFR-48FPS 3D(eg. The Hobbit) is now possible at home.

1536 kHz is absolutely crazy at this point. I don't think there's any audio content recorded at that sampling rate.

Yes, all these specs sounds like overkill. But that doesn't mean we're not allowed to expand. There may not be any content that requires such bandwidth now. But the sky's the limit. This means that creative artists has a larger playground to express themselves without being limited by old technology.

The ball's in Blu-ray's court now, with their revision. I really hope to see 4K video, 3D HFR and Discrete 9.1 (or more) surround a reality from here.

Plus, it was easy for the HDMI Forum to do, as adding more channels of audio (and increasing sampling frequency) takes up a relatively tiny fraction of bit rate as compared to 4K video.

Don't know, IMO, there are very few worthwhile titles available 7.1

The 1536 khz, might be against 8 channels at 192 khz sampling?

I agree this means that creative content artists will have a large playground to express themselves.

I think anything above 7.2 for the home is nuts (and even though some receivers support 11.x today, but those are derived channels), but I'm sure there will be those audio/videophiles, if there's hardware and software to support it, who will rig up individual surrounds and ceiling speakers to support those 32 channels. Except for the super-rich, this means that most people who do this will buy smaller, cheaper components, which means that the overall sound will be worse, not better. Personally, I'd rather have fewer channels of higher quality. This of course will only work in dedicated home theatres and in geeks' bedrooms because no significant other, no matter how technically aware, is going to let those surround and ceiling speakers in her living room unless they're totally invisible.

I think the audio will, like Dolby Atmos, have to be an object oriented model, because the studios are not going to spend the money to mix a 32 channel mix for home consumption when so few homes even have 7.1. And when it comes down to it, there aren't that many films mixed in 7.1. Those that are are mostly animated films. They'll take an Atmos mix and use it for BD and that assumes that Atmos will be successful enough to be used for many films and not just some big blockbusters.

Good to see all the discussion of HDMI 2.0 indicating Blu-ray movie watchers are also interested in broadcast and sports (4K @ 50/60 fps being almost minimally mandatory). As an aside, my Baltimore Ravens are playing Denver this evening and I’m hoping for the best despite the fact I hear the team’s been gutted in the off season since they won the Super Bowl.

But, on the movie side of things, given that the HDMI 2.0 overview (18 Gb/s) has now been ‘officially’ announced, I find it curious that the video journalists (cnet, etc.) haven’t run the numbers to see if this data rate is sufficient to support 4:2:2 chroma @10-bit per channel. I mean are cinephiles satisfied with 4:2:0 chroma sampling @ 8 bits so a potential (or lack thereof) to upgrade the PQ in this area in the future is of no concern?

It is a concern, but IMHO, Hollywood will resist 10 bit, 4:2:2 and I would wager they will never release anything for consumer use in 10 or 12 bit, 4:4:4. Another problem is H.265, in the first round we only get 8 bit, 4:2:0. Other bit lengths may come with future extensions to H.265. We shall see.

Wendelllllll! Is there a difference between IMHO in post #19 as opposed to IMO in post #20….inquiring minds want to know.

Good wager on the 4:4:4. But as far as bits and sampling ratios, people should not rule out HDMI 2.0 support for 4k 4:2:0 @ at least 10 bit when the Forum reveals more details.

As to HEVC and one of the ways to implement it, attention to our friend vargo if he is following this thread. Varg - Jason Garrett-Glaser (lead developer of the x264 project) has publically supported Telestream in the founding of the x265 project (https://forum.blu-ray.com/showthread...rs#post7997874 )

I agree, that we will not see 4:4:4 in the consumer market, unless storage technology improves, that could actually store 4:4:4 or even RGB. I have belief that we may see 4:2:0 10-bit as part of the 4K Blu-ray spec, HEVC's main 10 profile supports 10-bit. As I read it, a device/decoder that conforms to Main 10 also supports Main, which could mean as you stated, 10-bit being introduced later on, providing that the player has the Main 10 decoder.

What's interesting is that HDMI 2.0 may support 4:2:0, so what will be the minimum outputted space and bit depth for 4K Blu-ray? 4:2:2 10-bit, same as current Blu-ray?

The 4K Blu-ray specs are going to be interesting.

Last night I was perfectly satisfied that we have no broadcast distribution or home infrastructure (HDMI 2.0) available yet to consumers for 4K 60fps, as I believe the thrashing that my Ravens took would have hurt more seeing it in 4K.

I was thinking they would lose but not that bad.

That Welker catch (or non-catch) is what did them in. They never recovered after it.

What about 3D improvements? Any chances for 1080p60 for 3D games?

[BozQ]

I remember someone around the forums here said Oblivion was mixed in Atmos first.

I understand that it's near impossible to recreate Atmos for home theatre. Which is why I said 9.1 would be the next logical upgrade for home theatre audio after 7.1.

I just checked again, the 9.1 bed that Dolby recommends is your favourite 7.1 soundtrack overhead left and overhead right.

Lucky guess, I guess.
