My bad oztech, the sentence should have read the human ear cannot distinguish sampling above 44.4Khz. Its been a long afternoon at work.
I understand that the higher sample rates are used to preserve waveforms in the studio. As to whether the listner can actually distinguish in a blind test what the sample rate is, is audiophile territory and im not going there.
I'm just very annoyed of the massive missed opportunity for CE industry to adopt display port or some variant. I can predict a future with HDMI 2.0, 2.1, 2.2 .........and we all know how that went.
Time to look into getting some timeless mono-block amps for my theatre and just update the receiver for each new variant i guess (8k?). I'm over the upgradeites these CE company's love to force on us because there sales are falling.

I agree. This is the question I would like answered. I want to go beyond 8-bit color.

So if I'm reading this right, 1.4 HDMI will do 4K but not at 50-60 HZ so anything fast moving (sports, auto racing etc.) would be jittery. If that's true, I'd wait for 2.0 because I'll never fall into the upgraditis trap. I try and keep my equipment for years. It seems with 7.1/9.1/11.1 already out and all the new codecs that are now out, HDMI 2.0 would be nice to have and with all previously mentioned, would really future proof your sysytem for years.

If I'm understanding this correctly, full 1080p @ 24Hz requires 16 Mbps. My local cable company would have a hard to pushing that to most of their customers, let alone 4K content at 24Hz or more. So for cable and sports I wouldn't worry about 4K content for a long time.

The fact of the matter is UHDTV content is coming, simple as that. The gear has to necessarily precede it. The AVRs will. The sources will. The displays/projectors will (and already have). So then, here arrives the HDMI spec.

After the 2.0 AVRs become avail (although really not necessary), all one needs is a display (again, already here), a "blu ray" source that yields 4k (HAS to arrive soon), to watch 4K. Plenty will latch on. Including ME on the PJ front when they become "affordable" for us mere mortals in the next few years.

But no content.... 😡

Just my $0.02... 👍😉

Actually Sony has 4k streaming, new games support much higher res than 1080p, medical offices use higher res video and images, plenty of cameras support higher res, some sports channels are prepping for higher res and even 1080p content can look better when upscaled on a GOOD upscaler.

Just my 2 cents.

Not to mention no 4K content.

Reasonable is a very relative term - http://www.engadget.com/2013/09/06/lg-77-inch-curved-uhd-oled/ $15,000 for a 77" UHD OLED seems quite reasonable when compared to this years prices on much smaller non 4k OLED TVs. However the right price point for me is an 80" 4K OLED and under $9,000 (of course if 85" was available at the price, I wouldn't complain). I could see that happening within 2 years.

So who will be first out whit a HDMI 2.0 AVR?
post #39 of 44
I already have my money on Onkyo's top models to include it....the 10xx, 30xx. and 50xx. They (Onkyo) have never delayed their top AVR announcement this long and I don't readily see much of a reason for it (the delay) outside of throwing 2.0 into them. We'll see what develops.

Before we get too enthused about "easy firmware updates to HDMI 2.0" or "how soon new HDMI 2.0 capable AVRs might appear", it's probably worth re-reading some of the HDMI 1.4 FAQs...

Quote:
"Are manufacturers required to implement all of the new HDMI 1.4 features? (link)

No. HDMI technology is designed to enable a wide variety of manufacturers in different markets to implement the feature sets that work best for their customers."
Quote:
"How will I know which HDMI 1.4 features are implemented in a device? (link)

Shop for the specific features that interest you, rather than shopping for an HDMI version number and assuming that a certain feature is supported. Since many of the capabilities detailed in the HDMI 1.4 specification are optional implementations, it’s the responsibility of the manufacturer to tell you what features are supported in any given device."

There's a 99.9% chance that the first AVRs containing it will arrive in the next 2-9 months. My loose understanding of the "firmware upgradeable" devices is that they are "really" 2.0 hardware equipped and were simply shipped "non 2.0" until the spec was ratified and will be "updatable" at some point. I seriously doubt any avr will be included in this arena, but only some of the very recently released mega-buck 4K televisions and projectors.

Well, the Emotiva XMC-1 is shipping in 2 weeks with HDMI 2.0. If you are willing to drop $2k on a pre/pro (or $1199 with a discount card). Throw in a UMC-500 and you got yourself an HDMI 2.0 AVR, albeit at flagship AVR pricing.

The new HVEC file compression technology claims to be able to change the math for bitrates:

http://news.cnet.com/8301-1023_3-57501769-93/new-hevc-video-compression-wins-big-over-todays-standard/

"A new compression technology represents a significant improvement over today's standard, a new study found. The result could help pave the way for video with at least four times the pixels of today's 1080p standard."

Did you include this in your bitrate estimate?
