Dolby Vision and Low Bitrates

...and our 4K bitrate maxes at 16Mbps


This Q&A doesn't address what happens to the picture quality of
DV encoded content at low bitrates.

Anyone have an OTT service and watched DV content on a DV
enabled TV during a time of high Internet usage (when the OTT
bitrate is likely to drop)?

Can I stream Netflix in Dolby Vision or HDR?

Netflix supports two different HDR streaming formats, Dolby Vision and UltraHD Premium (HDR).

What You’ll Need:

• A TV that supports either Dolby Vision or HDR and Netflix. (If you use a set-top box to stream Netflix, both the set-top box and TV must support HDR.)
• A 4 Screen Netflix plan. You can check which plan you're currently on at Netflix.com/ChangePlan.
• A steady internet connection speed of 25 megabits per second or higher.
• Streaming quality set to High. More information about video quality settings can be found in our playback settings article.

I was mainly interested in how the video codec artifacts appear
when DV is used, does DV make the artifacts more obvious?

When playing DV content, if you encounter heavy traffic, you more likely to have a drop session when buffer/stream speed cannot be maintained. That has happened to me a few times during unusually high demand Netflix streams. The artifacts appear really no different IMHO. The compression used by Netflix 4K makes artifacts somewhat present in very dark and very bright scenes, where as the actual BD or 4K media is without it.

Delivery of streaming UHD services in general should improve in the future with the development of the new video coding standard, Versatile Video Coding, of which over 30 organizations answered the call at the San Diego meeting including that of InterDigital Communications and Dolby having contributed their proposal as indicated a couple weeks back…. https://forum.blu-ray.com/showthread...x#post14962558

Interesting, was reading more about it at http://news.itu.int/versatile-video-...arts-strongly/

The new standard is expected to enable the delivery of UHD services at bit rates that today are used to carry HDTV. Alternatively, using VVC would enable twice as much video content to be stored on a server or sent through a streaming service.

And yet Dolby Atmos gets a major hit when encoded for streaming or broadcast... the studio use print-outs that are basically fixed channel versions without scalability or 3D positional objects as originally trumpeted to save bandwidth. These compromised Atmos mixes are starting to show up on UHD Blu-ray discs, not just streaming or broadcast versions.

Streaming is sucking the life out of everything... severely squashed video, lossy audio, substandard Atmos, etc.

The industry started with music and now this...

We're going backwards not forwards.

Yep, whats playin out is exactly like mp3 era. Took bandwidth catching up for lossless downloads and streaming, and even now, not fully there. Few bands i enjoy you cant buy a non mp3 of i got feeling were a good decade away from a true disc quality streaming capability for movies, and in the meantime we get to suffer

There is Kalidascape (sp?), but the cost of admission is steep, the files are DMR'd and tethered, and it almost went bankrupt once.

ITUnews didn’t report on this….https://forum.blu-ray.com/showthread...p#post14970910
for which we’ll take a little deeper dive into its adoption progress at a later date.

Of squeezing the life out of video and audio? That doesn't sound like technological progress to me.

It's convenience trumping quality.
