HDMI 2.1 Allows for Dynamic Metadata


In addition to increasing the bandwidth from 18Gbps to 48Gbps, allowing for 8K at 60P and 4K at 120P, and improved audio handling, the new 2.1 HDMI standard improves dynamic range and HDR potentials significantly by allowing scene by scene settings rather than a global setting at the start.  See this article for more.

No 4K Streaming Until 2020?

And by 2020 8K should be the new 4K.

This 2020 prediction for 4K comes from Thomas Edwards of Fox Networks.

With Apple’s lack of buy-in to 4K, and the general lack of 4K content, 4K still has more challenges than it should.

Jan Ozer expressed a similar sentiment in April of 2015:

UHD 4K is being encoded by Netflix at 15Mbps. Can they deliver 15Mbps? They had trouble delivering 2 1/2 Mbps. [They are] averaging 3.4Mbps over FIOS, which is one of the fastest systems out there. Even if the TV sets were out there, even if the content was out there, can you deliver 15Mbps video to these UHD sets? The answer is unless you have your own pipes, probably not.

Jan Ozer has a very interesting presentation you can read here.

The take home message appears to be that unless you’re willing to put in extra effort to take advantage of your 4K television, or unless you’re working in media production, it really isn’t 4K’s time yet.  There’s no rush for most people to get a 4K, and we’re saying that as 4K enthusiasts.

Google Chrome 4K Tip

Thanks to Francois Beaufort for this tip that works with the developer channel version of the Chrome Browser:

The chromium team is currently working on smoother video frame rendering for HTML5 videos in Dev Channel. You can try it now by enabling the experimental flag named “New video rendering path for video elements” at chrome://flags/#enable-new-video-renderer and restart Chrome.

In practice, that means that if your computer was on the edge of playing 4K60, 4K, 1080p60 videos on YouTube for instance (hiccup every few seconds), it should now play smoothly.

If that’s not the case, please report an issue at http://crbug.com/new or press + + i.

V-Nova’s Perseus 4K Streaming Technology Shows Promise

The BBC has recently released an article titled V-Nova streaming tech produces 4K compression ‘worth watching’ that is an important development in the adoption of all things 4K.  V-Nova is stating that they can stream 4K in 7-8Mbps as compared to the 12-16Mbps that Netflix presently uses for 4K.  V-Nova also has some big names behind it like Intel and Sky which is a good sign for 4K.
