CEA: UHDTV is 8-bit, 3840x2160

Quote:
NEW YORK—The Consumer Electronics Association has announced updated core characteristics for ultra high-definition TVs, monitors and projectors for the home. As devised and approved by CEA’s Video Division Board, these characteristics build on the first-generation UHD characteristics released by CEA in October 2012. These expanded display characteristics (CEA’s Ultra High-Definition Display Characteristics V2) – voluntary guidelines that take effect in September 2014 – are designed to address various attributes of picture quality and help move toward interoperability, while providing clarity for consumers and retailers alike. “Ultra high-definition TV is the next revolution in home display technology, offering consumers an incredibly immersive viewing experience with outstanding new levels of picture quality,” said Gary Shapiro, president and CEO of the CEA. “These updated attributes will help ensure consumers get the most out of this exciting new technology and will provide additional certainty in the marketplace.” Under CEA’s expanded characteristics, a TV, monitor or projector may be referred to as Ultra High-Definition if it meets the following minimum performance attributes: — Display Resolution – Has at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically. — Aspect Ratio – Has a width to height ratio of the display’s native resolution of 16:9 or wider. — Upconversion – Is capable of upscaling HD video and displaying it at ultra high-definition resolution. — Digital Input – Has one or more HDMI inputs supporting at least 3840x2160 native content resolution at 24p, 30p and 60p frames per second. At least one of the 3840x2160 HDMI inputs shall support HDCP revision 2.2 or equivalent content protection. — Colorimetry – Processes 2160p video inputs encoded according to ITU-R BT.709 color space and may support wider colorimetry standards. — Bit Depth – Has a minimum color bit depth of eight bits. - See more at: http://www.tvtechnology.com/article/...yFHLaZ.dpuf;;;

because one of the first ways consumers will have access to native 4K content is via Internet streaming on connected ultra HDTVs, CEA has defined new characteristics for connected UHDTV displays. Under these new characteristics, which complement the updated core UHD attributes, a display system may be referred to as a connected ultra HD device if it meets the following minimum performance attributes:

— Ultra High-Definition Capability – Meets all of the requirements of the CEA Ultra High-Definition Display Characteristics V2 (listed above).
— Video Codec – Decodes IP-delivered video of 3840x2160 resolution that has been compressed using HEVC* and may decode video from other standard encoders.
— Audio Codec – Receives and reproduces, and/or outputs multichannel audio.
— IP and Networking – Receives IP-delivered Ultra HD video through a Wi-Fi, Ethernet or other appropriate connection.
— Application Services – Supports IP-delivered Ultra HD video through services or applications on the platform of the manufacturer’s choosing.

CEA’s expanded display characteristics also include guidance on nomenclature designed to help provide manufacturers with marketing flexibility while still providing clarity for consumers. Specifically, the guidance states, “The terms ‘Ultra High-Definition,’ ‘Ultra HD’ or ‘UHD’ may be used in conjunction with other modifiers,” for example “Ultra High-Definition TV 4K”.

In addition, CEA is working with its member companies to develop a UHD logo to assist consumers in identifying UHD products in the marketplace that meet CEA’s guidelines. The logo will be made available for voluntary use by manufacturers for product packaging, marketing materials and promotional activities. The companion voluntary logo program is expected to be launched later this year.

*High Efficiency Video Compression Main Profile, Level 5, Main tier, as defined in ISO/IEC 23008-2 MPEG-H Part 2 or ITU-T H.265, and may support higher profiles, levels or tiers. by Deborah D. McAdams

CEA has specified new voluntary guidelines for 4K UHD TV including using 8 bit color ITU-R BT.709 standards.
I'm Understanding this is a new voluntary option in addition to the existing 10 bit ITU-R BT.2020 standards ?
Maybe this will allow for lower priced 4K panels and facilitate web streaming ?
I'm no expert at these matters so if anyone would care to add to this thats would be good.
Another discussion could be 10 bit vs 8 bit UHD 4K color

Hires Music formats ..............."Why does it sound like a CD ?" ............. can we make it louder "?

It says it's a voluntary standard, so probably. Are there any UDHTVs that accept/display the 2020 standard?

It looks like just a voluntary standard and listing the features for a new CEA UHDTV logo. They basically seem to be taking what quite a lot of this year's UHDTV TVs can do today and making those the minimum standards, updated on first generation ones. Weren't there HDMI 1.4 "UHDTV" TVs that could only accept UHDTV content up to 30Hz? It looks like they won't be able to call themselves UHDTV or at least not get the new logo as it's a minimum of 60Hz which is good, but it doesn't make 120Hz etc. a minimum. They will also be limited currently by what HDMI 2.0 can do (though wasn't it Vizio that could do 120Hz over HDMI 2.0?). Basically it just seems to be an updating of their standards from the previous year (or whenever it was last done). But it doesn't seem like they've made a proper effort on getting a high quality standard set. Though the other standards bodies are still deciding on various standards.

I think they (the CEA) should probably have created at least another UHDTV1 standard for TVs (eg. version B) with minimum requirements for a better version of this standard (eg. must allow 100/120H/150/240Hz input, rec2020, etc. high dynamic range various other things), which might help the manufacturers want to create UHDTV TVs with the better standards. But again they're also limted by HDMI and standards bodies still deciding on various parameters.

There are 3 phases to UHD standards. The first phase is happening right now 2014 where just resolution is being implemented by the manufacturers. They unfortunately want little by little increments to eventually round out what the standard is proposing or the full enchilada of UHD. Can you imagine, manufacturers, content creators, SMTPE , ITU etc. hammering it out in a room and trying to agree on what UHD will be, I would like to be the fly on that wall, LOL.

At some point a few years down the road they will likely move to 10 bit or even 12 bit depth color and possibly an agreed by all parties wider color gamut all across the board. 4K blu-ray now has been mentioned that it won't be finalised till at least the end of 2015 with the possibility of seeing a player out in 2016. The 4K TV's now are still hybrids, 8bit color, possibly 8bit processing , rec 709 color space etc. This will all eventually change so early adoptors be ware, UHD content is an issue to , lack of it that is. It's out there in the production side but still yet to be finalised with content protection issues, etc.on the consumer end of things. This is one of the main reasons content supposedly hasn't arrived yet to consumers issues to deal with content protection. Right now it all seems like it's a big "mess" , half assed, support of the manufacturers , and production side of things , standards, UHD blu-ray , color depth etc. Time will tell.

Well of course there are several phases to the rollout. They need to get you to upgrade your gear multiple times. They can't push it all out at once or why would you buy a new blu-ray player, receiver, and TV set in 2 years?

Do you have a link to where they are now saying that? This link http://www.projectorreviews.com/tech...te-april-2014/ from April this year is saying the players will likely be out in "holiday shopping season" of 2015.

This is a good move as long as if they later increase the standards. The closest thing to rec 2020 was the Laservue DLP TVs which were only around 90% rec. 2020

Watch the videos of Your Next TV Conference
By The Numbers: What are the trends and forecasts?. The one English gentle man mentions that it will be the end of the next year the earliest. This confirms what you were saying. Check out the video either way it's quite informational.

Actually what was said in the "Your Next TV - by the numbers" conference was Blu-ray 4K/UHD hardware would be out by the end of next year (2015) at the earliest while what I wrote for Projector Reviews was a forecast that that the first Blu-ray 4K/UHD players and software would come out for the holiday shopping season at the end of 2015. We were both saying the same thing, more or less. I would place the confidence in the players and software starting to ship by the end of 2015 at perhaps 60% and they may very well slip into 2016. However, late 2015 remains possible.
