HDMI 2.0 Officially Announced
jones_supa writes with news that HDMI 2.0 is out. From Engadget "The folks at HDMI Licensing are announcing HDMI 2.0 officially. Arriving just in time for the wide rollout of a new generation of Ultra HDTVs, it adds a few key capabilities to the standard. With a bandwidth capacity of up to 18Gbps, HDMI 2.0 has the ability to carry 3,840 x 2,160 resolution video at 60fps. It also has support for up to 32 audio channels, 'dynamic auto lipsync' and additional CEC extensions. The physical cables and connectors remain unchanged."
Just like HDMI 1.4, the specification is only available to HDMI Forum members.
!So we won't see a markup in price on 2.0 cables then. If only.
Waiting for an amusing sig.
The summary doesn't say...
Does HDMI 2.0 support new, improved, and even more delicious Digitally Restricted Media? Seems that it must.
I am selling platinum-tipped, lead-shielded, kevlar-reinforced Ultra Mega HDMI 2.0 cables for the low, low price of $200/ft.
Given that HDMI is all about DRM, how many new ways have they come up to limit what we're 'allowed' to do?
And as far as yet another HD 'standard', I can't say I'm in a big rush to get this. The media companies seem to think we'll replace all of our equipment every 2 years or so when they come out with the new hotness.
But replacing my TV, my Amp, my DVD player ... well, I'll get around to it eventually. Since my current stuff is only about 2 years old, I don't see caring about this new spec for some time.
Though, for a computer monitor, those resolutions sound pretty awesome.
Lost at C:>. Found at C.
See this is the sort of thing you see from laymen all the time. Listen to the GeekSquad expert next time. The gold connectors round out the 0s and sharpen up the 1s. This is really simple, come on.
"Version 2.0 of the HDMI Specification, which is backward compatible with earlier versions of the Specification[...]"
It is what it is.
HDCP!=HDMI
systemd is Roko's Basilisk.
Have they fixed the lack of closed captioning in HDMI? I haven't seen it mentioned anywhere.
"I'm a Genius!"*
*Not an actual Genius
And display port exists specifically so they don't have to pay the royalties for HDMI,
I should use this sig to advertise my book ISBN-13 : 978-1501515132.
1920 multiplied by 2 is 3820.
3820x2160 is merely Quad-1080p - which at least is sane.
4096x2160 is 17:9 (ish) - I don't see the point in this resolution.
I await the pointless 5040x2160 monitors (21:9, the "new shiny standard" for widescreen monitors).
You think BestBuy was greedy?
Just watch as Hollywood and TV producers try to shovel this crap on next! The 3D TVs, TVs with apps, and all sorts of ugly non sense to charge for premiums. Cox and Time Warner would love to charge $499 a month for TV with all sooo brilliant 5k!
You know there will be suckers lining for this too as always.
$199 a month per TV in addition to the $499 a month. At $700 a month you can fucking trade that in for a car! But consumers will of course pay for it with their 30% interest credit cards and then whine how they are soo broke and can't retire. Sigh ... ok going off topic here but just a dark observation I have made when it comes to consumables in the past 10 years I have seen.
Now I am considered a money waster by these people for buying $250 video cards and decent computers every 4 years too.
But when stuff like this comes out marketers always look for a way to exploit it. I am fine with regular HD and nothing else but perhaps I am a minority?

Still limited to 60Hz? Disappointing and annoying.
Well when i was working on RF stuff, there was a lot of silver and gold of course. Skin effect and all and good connections were important to avoid reflections. Since a HDMI cable is working as a high frequency broad band cable. I can see cheap cables not working. Reflection on incorrectly or poorly terminated sockets could really stuff things up. Digital in a computer is far from 1 or 0 at these kind of bit rates. Signal eyes from these can be .. unpleasant. Error codes are used for a reason.
Of course i don't buy the expensive cables either. But we are not talking about "warm sound from correctly polarized oxygen free isotopically pure" monster cables.
If information wants to be free, why does my internet connection cost so much?
HDMI is video and audio transport. Closed captioning works fine over it, since it comes from the video source. Be it your cable, DVD, Blu-ray, whatever, the CC information is processed on the relevant device, and then sent out as part of the video.
Asking HDMI to do closed captioning is like asking Ethernet to do packet filtering: You are looking at the wrong area.
my blu rays play just fine on my TV. what exactly am i missing?
You're missing the ability to access the HDMI channel, more specifically the HDCP channel, that your Blu-Ray disc is playing across. Many would use this access to record/copy the video stream, possibly for piracy which is what the DRM is designed to prevent. But, many others would like to be able to access the video stream to do things like:
* Add our own news crawler, or pop-up alerts from our home automation systems.
* We'd like to pop-up caller ID from our PBX while the video is playing.
* Allow the home automation system to mute the Blu-Ray's audio and make an announcement.
* We'd like the ability to switch video feeds on a particular HDMI interface in software, so we don't have to use convoluted mechanical HDMI switchers and computer controlled IR blasters to control the HDMI switch.
* Similar to above; switch our security cameras/gate video on the fly.
All of these things were possible with previously unDRMed interfaces. But, using those interfaces now cause the Blu-Ray player to artificially and significantly reduce the playback resolution. Instead of watching 1080p, the Blu-Ray restricts the video down to 720p or less.
Windows 7 does nothing at all with Blu-ray content. It doesn't understand how to play it. All it does in relation to any of this is provide a method for programs to inquire to drivers if everything is (supposedly) secure. A Blu-ray player can inquire as to the encryption status of the links and make sure things aren't being captured and so on. For that matter, so can other programs. It isn't Blu-ray specific, however only the media companies give a shit so that's all that really does it. Games don't mind at all if their output is being captured.
Doesn't matter the interface. DVI, HDMI, and DP can all encrypt the signal. There's nothing special, on a computer at least, about HDMI.
It is then up to the software how it acts on that. However, due to licensing requirements, the software has to disable the video out if everything isn't encrypted. If it doesn't they won't be able to get a license for the keys to decode the media.
Same deal on any platform. It isn't like Windows is special in this way. If your chosen platform doesn't support the necessary "protection" then there won't be any licensed Blu-ray playback software.
This is a media industry thing, not an OS thing. The OS provides the ability to have verified driver paths, but it does nothing at related to changing anything. That is up to the software, and that is dictated by licensing.
http://www.hdfury.com/ Makes any DVD player 100% compatible with any TV. And it removes ALL of the useless encryption and DRM.
Do not look at laser with remaining good eye.
HDMI is a pure digital signal, with error checking. But since there's no means of retransmitting a broken packet (and thus no valid reason for buffering) in actual practice it's less capable of error checking and bit regeneration than methods used by scribes in the ninth century. You can know you lost more bits than you can regenerate, but you can't do anything about it.
I think this is because HDMI is not really a method for clean digital signal transmission, but rather a way to stealthily carry HDCP into the consumer mainstream. The feature set is primarily aimed at preventing users from doing things (like making backups) rather than providing the maximum benefit to end users.
This is clearly either a misconfiguration on your TV, your computer, or a design flaw in the TV, or your computer based on the simple fact that many people who use HDMI to connect their TV to their computer don't experience this problem.
Someone explain to me again why 1920x1080 resolution is so horribly inadequate that we need 3840x2160 (4 times the resolution)? Are we all expected to have Jumbotron-sized televisions in our living rooms now?
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
It is not a problem with HDMI. Apparently the author doesn't like cleartype. Just disable it if you don't like it. The fonts will come in razor sharp, unlike the pictures of how it looks over VGA, which is just blurry.
