Netflix in 4K and HEVC Decode
The NVIDIA SHIELD is currently the only Netflix 4K-certified set-top box in the market. This certification involves two important requirements:
- Presence of a HDMI 2.0 port with HDCP 2.2 capability
- Presence of a hardware decoder for HEVC Main and Main10 profiles
NVIDIA was the first in the PC space to bring HDMI 2.0 together with HDCP 2.2 support as well as a hardware decoder for HEVC in the GTX 960. They are also extending this lead to the SoC space with the Tegra X1. Thus, the NVIDIA SHIELD Android TV has turned out to be the first set-top box to meet Netflix's criteria for 4K certification.
The UltraHD-capable Netflix streaming plan is the highest-end one, coming in at $11.99 per month before taxes. If the SHIELD is connected to a HDMI 2.0 4Kp60 sink supporting HDCP 2.2 and the Netflix account is on a supported plan, the Netflix app's UI presents a row of Ultra HD 4K streams in addition to the generic categories. We tested out Netflix 4K on a Samsung HU6950 without an AV receiver inbetween.
Netflix has a special test stream that shows the characteristics of the currently playing stream. As expected, the SHIELD had no trouble in getting to the 4K encode.
In the adaptive streaming process, we came across a host of different encodes. They are listed in the gallery below.
Regular readers of our HTPC reviews might remember that the Windows 8.1 Netflix app tops out with a 5.8 Mbps 1080p H.264 stream. On devices with HEVC support, it appears that this is replaced by a 5.16 Mbps HEVC Main10 stream at the same resolution. There is also a higher bit-rate version (6.96 Mbps) with similar characteristics. Beyond that, we have the 4K stream at 9.6 Mbps. Unfortunately, we don't know the exact characteristics of the encode, but, based on the immediately preceding lower bit-rate streams, it is probably a HEVC Main10 encode too.
The Netflix app gives us an indication that the SHIELD has no trouble with HEVC. In order to confirm this, we put our HEVC test suite through Android's native Video Player.
The video shows perfect playback of 4Kp24, 4Kp25 and 4Kp30 HEVC Main and Main10 profile streams. For 4Kp60, we only have Main profile videos, and the SHIELD has no trouble with that.
On one hand, it is nice to see the SHIELD Android TV's 4K Netflix capabilities as well as support for high frame-rate HEVC playback in a power-efficient system. Though the 4K TV adoption rate is still very low - it's the start of what will be a long process - of anything and everything NVIDIA needed to do to secure their spot as the set top box to have for 4K TVs, getting Netflix 4K support in place is it.
On the other hand, it also reminds us of the sorry state of HTPCs with respect to HDMI 2.0, HDCP 2.2 and HEVC playback. For enthusiasts, it is imperative that PCs catch up soon, given that local media streaming is not a focus point for the SHIELD.

the chip and the wires (hdmi) have the necessary bandwidth, so shouldn't be a issue.Haydon987 - Thursday, May 28, 2015 - link
Shouldn't be in the case of dozens of currently existing devices, but in every case so far of any publicly available hardware I've seen, all encrypted content comes out 4:2:0 at 4k, so it would be nice for a vendor to acknowledge if it plays 4k hdcp 2.2 at 4:4:4 or just plays unencrypted stuff (like games, menus, ads, etc.) at 4:4:4 at 4k. Until a vendor specifically states it, I have my doubts. Sure all the features are listed to make it sound good to people who don't look too deeply into it, but they don't state when the features are interoperable.It's like a person listing for a spec sheet about themselves:
1. I can run 17 miles per hour
2. I can run 25 miles
This does not mean that this person can run 25 miles at 17 miles per hour. They are just 2 separately listed specs. Chances are they only maintain that speed for a few seconds.
In this case what is most likely:
1. I can play without color compression (4:4:4)
2. I can play protected content at 4k (hdcp 2.2), but I won't tell you if that is compressed or not.

That is definitely an interesting question, but it is somewhat moot.. let me explain:Getting specs out of the way, the SHIELD does support RGB 4:4:4 at 4Kp60 on the HDMI port.
Now, all video content that consumers play back - Netflix or Blu-rays and the like - they are all encoded in 4:2:0 - In this case, the consumer has nothing to gain or lose whether the conversion to 4:4:4 is done on the source side or the sink side. So, HDCP 2.2 with just 4:2:0 support is fine.
On the other hand, for professional applications, where content is processed in 4:2:2 or even 4:4:4 format, it will be a problem - but, it is likely that the workflow process in that case doesn't involve protected content - the protection is applied / needed only on the consumer delivery side.
Again, this is an interesting aspect, and one that I will definitely be questioning HDMI source / sink vendors on. It is just that it doesn't matter for consumer applications.

I'm interested in trying this with a hdhomerun prime with the live tv app. Does this android tv device support mpeg 2 decoding?457R4LDR34DKN07 - Thursday, May 28, 2015 - link
"The typical media library also includes TV programs that are interlaced MPEG-2 (for example). The SHIELD is currently not a good solution for such a case."Thanks, not for me then

The Live Channels app supports hardware MPEG-2 decoding, including deinterlacing. That functionality just isn't available to other media playback applications, since it was licensed for just the Live Channels app.DanCar - Thursday, May 28, 2015 - link
The recommendation row can be turned off partially or fully in settings -> System Preferences (3rd row) -> home screenYou can select which sources to enable and disable.

Somehow, I am not able to follow the path you are referring to..Under settings, I have Device > System, and under that nothing about Home Screen.. Do you have a video or set of screenshots showing the path?
I know that it is possible to go into the settings of a particular app and turn off the Notifications for that app - on Android TV, that turns off the 'Recommendations' - this is what I had done for the YouTube video showing the Android TV UI. The Recommendations row doesn't seem to have an option to turn it off completely..

I was hoping they spent the money and licensed the codecs but no HD Audio or DTS (or MPEG2 or VC1) is a bummer. At least in the case of the video codecs the CPU is fast enough to decode in software. Will not replace my HTPC. Its funny they license them for their videocards, including their cheapest passive ones but not their premium set-top box. And the box doesn't even have to decode it, just pass it through to a receive, that shouldn't require a license at all.One thing that was unclear in your review though, if I use HDHomerun/Live TV app will it decode and deinterlace MPEG2 via hardware since the app is licensed? If so is this supported on Shield like it is on Nexus Player?
At least they shipped with working Netflix, unlike Razor.

Why is a license needed if its just bit-streaming? If i connect it to my amp and my amp separates the hdmi video from the audio signals, why would the licensing matter on this box?
