You make a good point about SMPTE though I would mention that THX does give a recommended viewing angle of 40 degrees for home theater. 4K UHDTV will change that though I think that there are many...

Digital HDTV did well but the same can't be said for D-VHS, HD Laserdisc, and analog HDTV. That something is better isn't enough it has to be noticeably better and be sold at a reasonable cost.

The final specification for 4K Blu-ray won't be released until next year but the current plan is that it will use HEVC to support 10-bit video with resolutions up to 4K at 60 fps.

I hope that BT.2020 will be supported when they decide on the final specs for 4K Blu-ray. My great worry is that the CE companies will choose short term sales over long term success.

My guess is that the website which posted that it was backward compatible made a mistake.


4K Blu-ray, and future premium UHDTV services, will most likely require HDCP 2.2.
