So everyone should buy the 4k tv's that will be on sale in 2015 before buying. ?

Even that will not guarantee 100% compatibility. You need to look at the specs. closely and possibly hold off for a competent, professional review of the display you might be interested in. Gotta cut through a lot of marketing B.S. to get to the tangible capabilities of the set.

If your 4K TV has HDCP 2.2 that should be sufficient for copy protection protocols - this covers a number of TVs released in the last year.

AV Watch has posted some details about Ultra HD Blu-ray. The article includes several Japanese slides from Panasonic and here is a short summary:

Bit depth: 10-bit for HEVC. 8-bit for AVC.

Chroma subsampling: 4:2:0.

Color space: BT.709 (standard dynamic range only) and BT.2020. Also has SMPTE ST 2086 metadata (tells the player what color space the video really uses and for 99% of current movies that would be DCI P3), MaxFALL metadata (maximum frame average light level and the BDA recommends that it not be above 400 nits), MaxCLL metadata (for HDR video).

Compatibility: A slide shows a Ultra HD Blu-ray player converting the color space and/or the dynamic range so that the video can be seen on different displays.

Disc sizes: 50 GB at up to 82 Mbps, 66 GB at up to 108 Mbps, and 100 GB at 128 Mbps.

Frame rates: 23.976p, 24p, 59.94p, 60p for HEVC with 25p and 50p required for areas that use 50 Hz TVs. 23.976p and 24p for AVC.

HDR system: SMPTE ST 2084 which is the HDR system that is defined in the second version of HEVC. Some of the slides say something about 1,000 nits and 10,000 nits.

Peak video bit rate: 100 Mbps for HEVC and 40 Mbps for AVC.

Resolutions: 1920x1080 and 3840x2160 for HEVC. 1920x1080 for AVC.

And not just this last year but 2013 sets too. Without HDCP 2.2 a 4K TV will not be able to display UHD BD @ UHD res, it's as simple as that. But as long as it's got the right HDCP then you'll still be able to play back the most basic elements of 24fps 4K video, even if the TV isn't equipped with any flavour of HDMI 2.0.

As for the subsampling being at 4:2:0, I called it a while back, and Penton's reply of "I can neither confirm or deny" when I asked him about it was all but a confirmation. (I would search for the relevant posts but I'm sending this from my phone lying flat on my back in the Trauma ward at Poole hospital, having shattered my ankle while out walking on Monday, they operated on it yesterday and put lots of plates and screws in.)

Ouch! Get well soon, friend!

Don't bother searching. Indeed you did as you clearly understood my early hint back in-the-day. For those having compression knowledge, I became more specific with regards to chroma subsampling just a few days ago on Jan. 9, as that spec was not revealed in the usual CES 2015 interviews….too nerdy.

Sometimes it’s a precarious balance between what I can…and can not clearly reveal, but for those having interest/high hopes in seeing dem Hobbits in 48Hz frame frequency, months ago, I was a bit more forthright, see last paragraph

Extremely sorry to hear about your mishap . Hang in their mate! Best wishes for a quick and complication-free recovery. The only serious advice I can offer you is not to try to be a hero and tough out the pain or be too shy/embarrassed to ask Nursing for pain meds. You’re not going to become addicted to anything doctor prescribed over the course of your hospitalization. When you’re up to it, we’d love to see even a cell phone pic of the x-ray(s). We’ll take the one(s) prior to surgery so as to appreciate the significance of the injury.

Best wishes for a speedy and pain free recovery... You'll Be Back and running in the Boston Marathon in no time!

All the best, I'm just down the road from you then in Bournemouth. Small world....

And if the marketing spiel doesn't help you out, advanced users in professional facilities could test for 10 bit monitor capability by generating their own 10 bit gradient from left to light and then take the file into a program like this freebie…. http://www.thefoundry.co.uk/products...ning-editions/ to see if you are getting all of the code values you’d expect.

Any simpler way of determining if a display is 10-bit? A UHD Calibration or test video?

Hm. Still no 30p support, nor 48p for HFR.

[KubrickKurasawa]

Still sounds like a mess if you ask me.

No interlaced modes? So I'm assuming the inevitable Hobbit UBD (is this the abbrevation they're going with?) will be 60p with doubled frames from the original 48fps?

And still no 18fps (or similar, nor VFR) for silents. Maybe one day the technology for arbitrary frame rates will exist... outside of a .mkv container.

What's crazy about this list of support frames rates is that digital displays can switch to any frame rate automatically, so there should be no need to convert PAL TV shows that are shot at 25 fps or 50 fps to irregular cadences. However, they still only allow those rates for PAL countries!

Stupid, stupid, stupid!!

[Tech-UK]

Really interesting information on that page. The diagrams explain a lot.

HD SDR AVC 8-bit (current Blu-ray), HD SDR HEVC 10-bit, HD HDR HEVC 10-bit, UHD SDR HEVC 10-bit and UHD HDR HEVC 10-bit.



Looks like consumers are going to need to learn a lot more about this new technology on top of existing Blu-ray.

If they even do HFR, it will only be 2D.
The Hobbit was in HFR 3D. 48 frames per second per eye. So in total, it has to deal with 96 frames. Unless it's possible to pull this off in 1080p instead of 2160p.

Oh man, I feel your pain . Take care dude and follow the doctors and physical therapist programs for recovery. I spent several months in a hospital style bed with a really messed up left knee, it has several pins, screws and plates in it. I am VERY grateful to be able to walk without mechanical assistance.
