HDMI 2.0

post #1 of 44
Thread Starter 
"The board of the HDMI Forum has announced HDMI 2.0, which is expected to come out in the first half of 2013, with double the existing bandwidth -- enough for 4K at 60hz -- and support for the 21x9 aspect ratio, for example."

I just did the update on my 2 Denons and I wouldn't hesitate to do it again if they came out with a 2.0 upgrade board. I don't really need any more audio channels but I do want better support for 4K TVs as I'll be ready to get one next year if they make one big enough at a price I can justify.

Maybe I'm being a little pessimistic, but I can't see a big 4k TV reasonably priced anywhere in the next 3 years.

Not to mention no 4K content.

^Agreed.

Maybe you mean't 3 months instead of 3 years? =P

The 4K hardware may start to be available...
But no content.... 😡

Just my $0.02... 👍😉
post #6 of 44
4k Blurays are coming out soon

and my bet is digital media providers like Netflix and amazon will follow but to bad our Cable companies are still in the stoneage and prefer to nickle and dime is forever.

15-30 mb internet speeds and 1080i sources for our Cable TV and not true 1080P.

Give us high fiber optics already better yet. Get the 2gb versions from Japan biggrin.gif

I am hoping H.265 takes off pretty quickly (just like how H.264 did a few years ago). It is supposed to do better quality video for half the bandwidth or something like that. But, it is going to require more expensive and high power hardware at least in the beginning.

Theres lots of new 2013 AVR's comming out now, but no HDMI 2.0... Why not?
post #9 of 44
The HDMI 2.0 specification isn't out yet, so it would be a bit premature to see any devices implementing already.

The spec is still under wraps and they are working on it. It won't be until the end of the year or CES 2014 before we see the spec and then it won't be until 2015 or so that products with HDMI 2.0 show up as it takes at least one year before hardware can be finalized and bugs worked out.
post #12 of 44
And by then the video industry will have come out with a new, fantastic, video format or encoding and a new HDMI spec will be needed (which still will not be able to do what Display Port currently does)...
post #13 of 44
I plan on updating my AVR and TV (new TV won't be 4K) this year. To give some perspective, my current equipment doesn't have HDMI at all. From the above discussion, I take it that awaiting an AVR with HDMI 2.0 would likely be years, not months? I don't want to buy a soon to be "obsolete" or at least old technology if it means holding off for a reasonable period of time. Not more than about six months though. Thanks.
post #14 of 44
Look how long it took USB 3.0 to finally make its appearance somewhat widespread.
Thuderport would have been nice if the industry would have adopted it since it has plenty of bandwidth and can be daisy chained.

HDMI 2.0 was to be released in the second half of 2012. They then pushed it off to the first half of 2013. I suspect the official specs will finally be approved at the beginning of the fourth quarter of 2013, but that no consumer level AVRs will be available until the first half of 2014. If you do not have HDMI yet, waiting another year will not change your life any. At which point you will have an AVR that lasts you a long time.

Makes sense, I'll wait. Of course now I've worked myself into a frenzy obsessing about a new receiver. But as Spock said "it's the wanting, not the having". Sorry for the geeky, treckie moment.

Then the want really increases when the next model lineup does not include 2.0 then you realize you missed out on the features you wanted besides 2.0 for two model years.
post #18 of 44
The next models come out in April, right? Hopefully HDMI 2.0 will be complete this year so the AVRs can be manufactured in time for the normal release cycle.
post #19 of 44
Word has it that its been completed
post #20 of 44
My assumption has been consumer electronics manufacturers want to announce the availability of HDMI 2.0 products as soon as possible after public release of the spec. They may figure that, if HDMI 2.0 is announced, but products won't be available for another year, enthusiasts would hold off on purchases. (I realize that most people don't even know what HDMI is, let alone that there are different versions.) So, I'm guessing that by CES in January 2014, new products with HDMI 2.0 will be announced.

But, I'm just guessing here. No insider knowledge at all.
post #21 of 44
Hey! Just quick drop by question since I cant seem to find it and im curios if anyone else came across any info on it. Will the 2.0 hdmi actually support 1080p @ 120hz? Not as informed about the technicalities behind HDMI but I have been doing quite a bit of research recently. Thanks!
post #22 of 44
Technically HDMI supports any resolution that fit under the maximum bandwith, which for HDMI 1.3 and 1.4 is 340 MHz. Since 1920x1080 120 Hz with CVT-RB timings is within this bandwidth limitation, it's already supported by HDMI.

Whether any given device supports this resolution is entirely different quesiton. HDMI devices are only required to support 480p, support for any other resolution is optional. The 120 Hz non-3D modes are normally only supported by PCs and certain PC monitors, so you're unlikely to find any AV receivers or TVs that support any 120 Hz video mode. HDMI 2.0 isn't going to change this.
post #23 of 44
Official HDMI 2.0 announcement scheduled for Sept. 6th at a press conference at IFA in Berlin.
post #24 of 44
Nice, we will probably have HDMI 2.0 AVRs come the next April refresh time period. I suspect HDMI 2.0 video cards will come out pretty quickly since they have a fairly short product cycle.
post #25 of 44
HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specifications, significantly increases bandwidth up to 18Gbps and adds key enhancements to support continuing market requirements for enhancing the consumer video and audio experience. New functionality includes:

•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

Thank you HDMI org for including 32 channel audio in the HDMI 2.0 Spec, and thus making provision to accommodate the ETRI 30.2 channel theatrical speaker-configuration-and-codec . . . just in case that still only research lab concept gains (first) commercial acceptance, and (second) a consumer|home marketplace!

LEAD Technologies Inc. V1.01

But please tell me one more thing: Where the hell do I find an upgrade to convert my 8 channel audio limited WAF 1.4 into a 32 channel audio compliant WAF 2.0...? eek.gifcool.gifbiggrin.gif

Since the current pre/pro's and or AVR's around $750+ already handle 4K video, what does HDMI 2.0 in the real world really offer that is not currently available? Are 32 channels of audio really important to 99% of the people out there. I would bet 9/10 audio/video purchasers have never heard of AVS Forum and HDMI 2.0 will not effect 90%+ of video/audio purchasers. I'm looking to buy a Denon 4000 or Onkyo 929 and I'm trying to decide why I would wait for HDMI 2.0 and another six months before I buy. I've had my Sony TA-E 9000ES for 6-7 years so maybe I should wait since I keep purchases for quite a while! I do have a front projector, and will be buying a 4K projector in the next few years, but it seems the current pre/pros/AVR's already handle 4K video with the current HDMI.

In the real world, what will HDMI 2.0 do for me that can't now be done with the current HDMI spec. Is HDMI 2.0 more for the future than anything that can be currently used with it now?

How does a AVR change against 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

We have yet to see any broadcaster provides 4k content especially at 60 Hz. Look at the Hobbit shown in 48 Hz, not loved. You'll will see 20 Mbps 4k (24hz) streams early on, a HDMI 1.4b compliant AVR is fine with that.

The 32 audio channels sounds a lot like Dolby Atmos although that is for the theaters and can provide audio for up to 64 speakers. But yes extreme excess for a home theater application.

We had recent discussion about the benefits of 192 Khz 24 bit audio files, but now I suppose some would ask if a higher sample frequency (1536 kHz) would make any difference. This is way beyond any useful home/computer application IMHO. I imagine the file size would be huge. biggrin.gif

IMHO in the real world nothing in this new specification will impact you in the immediate future. wink.gif

Up to 1536kHz audio sample frequency for the highest audio fidelity

This is a very misleading statement. forget that the human ear cannot distinguish above 44.4Khz.
This figure is conjured up by using the 8 channel support at 192Khz. Pure marketing hype using big numbers again.

The question I want answers to but cannot find anywhere in the early specs is does HDMI 2 support 10/12bit colour at 4k 50/60hz?

Most humans can not hear above 20Khz but that has nothing to do with why we have currently 41,44,96 and 192 KHz for audio files now whether the listener can hear a difference between them depends.
