Local Media Playback Evaluation
The announcement of the SHIELD Android TV box generated a lot of interest amongst media streaming enthusiasts. It has continued to this date. Given that most of them prefer local media playback to OTT streaming, there has been marked interest in the local media playback capabilities of the unit. In this section, we attempt to set the expectations right on the various relevant aspects.
Display Refresh Rate
The Android TV framework forces the interface and most apps to run at 60 Hz. Obviously, a 24 fps film needs to be pulled-down with a 3:2 cadence to let the display be refreshed at 60 Hz. This creates a judder effect. Apps such as TVHZ were created to resolve this issue, but needs manual intervention prior to media playback. Kodi's currently existing 'sync refresh rate to playback frame rate' option doesn't work, but a fix is probably coming soon.
Codecs Licensing
Unlike a PC, the SHIELD Android TV is an embedded system. Therefore, codec support involves NVIDIA signing licensing deals. For example, support for Dolby Digital / Dolby Digital Plus requires deals with Dolby Laboratories, while DTS / DTS-HD support requires deals with DTS. On the video side, H.264 support, for example, requires a deal with MPEG-LA. Each of these deals ends up increasing the end cost for the consumer. In order to hit an acceptable price point while ensuring all necessary components for OTT streaming (SHIELD's primary market) are in place, NVIDIA has signed deals for the following audio/video codecs only:
- H.264
- H.265
- VP9
- Dolby Digital (Update: only bitstreaming, no internal decode to PCM)
- Dolby Digital Plus (Update: only bitstreaming, no internal decode to PCM)
This means that the native Android Video Player can only play back the above codecs (in addition to the free-to-decode / play ones such as PCM audio). This also means that the SHIELD Android TV will not be doing any HD audio bitstreaming in the near future unless things chance on the licensing front.
That said, players such as Kodi, MX Player etc. can opt to use pure software decoding when hardware decoding is not available. It is also possible for app vendors to purchase the license themselves and then work with NVIDIA to get hardware acceleration / support for that. For example, SiliconDust (the vendor behind HDHomeRun) is doing it with their Live TV app in order to get hardware decoding enabled for MPEG-2.
Attempting 480i60 MPEG-2 Playback with the Native Android Video Player
Video Post Processing
Deinterlacing and pull-down detection / IVTC are essential for watching certain live TV channels and other interlaced content. NVIDIA only guarantees video post processing for the licensed codecs that go through their hardwrae decoder. Third-party players will need to work with NVIDIA to ensure that any software decoded streams are correctly hooked up to the post-processing chain.
We tried processing the HQV Benchmark videos on the SHIELD to get an objective evaluation of the SHIELD's post-processing capabilities, but unfortunately the MPEG-2 encoded streams were not processed properly when decoded in software on Kodi.
Experimenting with Kodi
The Kodi 15.0 beta 1 APK is available for sideloading on to the SHIELD Android TV. On the bitstreaming side, we could only select DTS and Dolby Digital, and Kodi had no problems bitstreaming those streams.
We played back our test streams from a Samsung T1 portable SSD attached to the USB 3.0 port. HEVC streams played back with hardware acceleration inside the Kodi interface, but Kodi had trouble with TS files. For hardware-accelerated codecs, the power consumption at the wall was around 6 W. For software-decoded ones such as our 1080i60 VC-1 clip, the power consumption shot up to 11.5 W.
The SHIELD Android TV / Kodi combination has absolutely no trouble with the vanilla H.264 files that people usually rip their Blu-rays to. Fortunately, despite the lack of MPEG-2 and VC-1 licenses, Kodi's software decode is efficient enough to not cause frame drops. The absence of deinterlacing is an issue, but that should hopefully get resolved soon.
Based on our evaluation, the SHIELD Android TV is definitely not a comprehensive HTPC replacement - particularly from the local media playback viewpoint. That said, it does have support for all major OTT services and Live TV as well as future DVR capabilities (thanks to Android TV). For a certain set of users, it is possible that the SHIELD can replace their HTPC. However, one needs to remember that the unit is an embedded system with plenty of constraints and doesn't have the same openness and flexibility that a HTPC has to offer.

Certainly seems performant enough, but will it get any exclusives. Even to the entire shield platform at least. Android games are....Ok, but hardly take advantage of the latest and greatest chips, most run fine even on my Moto G. Streaming is also neat, but I'd really like to see some exclusives that really target these high end chips with controllers.ganeshts - Thursday, May 28, 2015 - link
Yes, NVIDIA has indicated around 20 exclusive titles are coming to Tegra K1 and X1-based SHIELD devices.Jumangi - Friday, May 29, 2015 - link
What titles. I hope no body thinks they will be even remotely close to AAA level experiences. No developer is going to risk that kind of money on this machine. They will be cheesed low end android crap.TheJian - Friday, May 29, 2015 - link
Not sure what you're talking about. With unreal 4 and unity 5 engine support on android now you'll start to see some REAL games and they already have real PC ports (serious sam 3, Trine2, Portal, halflife 2, KOTOR etc). You might say PC ports are old (but they are AAA games), but if you know the sales #'s of each of these you understand not more than ~10mil played any of these titles that NOW can easily be ported to Android for a FULL (albeit older) PC game experience. More of these will likely come first, but by this xmas or next we'll start to see what unity5 and unreal 4 can produce. We are already way past angry birds...LOL. Trine 2 isn't a great looking title? That's a 2011 PC game. What exactly do you want? Trine2 runs on K1, we're already at X1 and 14nm Samsung fabbed version is coming for xmas (likely with return of Denver cpu amped up and more polished). We are not even taxing X1 yet, and the xmas version at 14nm will eat it alive. You clearly don't browse android games much to see what is already ported or new out there.This console has more power than an xbox360 or ps3. Not sure why you'd think we're talking Minecraft here or something. If you called xbox360/ps3 AAA experiences what is the difference? You can call that barely beating last gen, but this is the new xbox360/ps3 experience for the poor (or alternative gaming for me that isn't PC etc) who can't afford xbox1/ps4 price tag nor the $60+ games prices that come with those.
On top of that, you don't need a $600-1000 PC to play at 1080p 60fps. For a monthly fee of even $15 (180/yr) you'd get FAR more than 3 console games at $60ea correct? Right now (free) you get 50 games that can stream like this and surely many more coming year after year. The sheer value of GRID gaming here is massive for a person who doesn't have $60 a month to keep their kid playing xbox1/ps4 games. I'm going to guess there will be a $10 fee for 720 and $15 for 1080p gaming but you can insert whatever numbers you want here, I'm just making the point about affordability for amount of fun you get. Mind you as graphics amp up, GRID keeps you from needing to upgrade. Nvidia can easily make sure you're always getting the fps that is being sold to you. They can keep dropping servers around also to keep latency in check.
To your dev point, incorrect. Worst case scenario they can make it exclusive for 6mo-1yr then if sales suck port to PC or allow regular android to use it. You are forgetting that 1yr from now ALL gpus (14nm by then everywhere) will have X1 levels of gpu and if that's not the case by then 10nm isn't far behind. Also if NV wins the suit, everyone will be paying for NV gpu IP (great for devs) at some point. IF you make an unreal4/unity5 game here, you can easily port the thing to PC probably in a few weeks tops and it is running the exact Nvidia hardware there for ~75% of the discrete market on PC's. You're mistakenly acting as if you make a TEGRAZONE based game (meaning special for NV tegra hardware effect), it can NEVER run anywhere else...LOL.
It took a few weeks to port most of these titles.

Just an example of your crappy games.. Looks pretty fun to me.

Listen to the dev. 1st time in 1080p on mobile etc. Can't beat the price of $6 either. Full 20+hrs just like all the other full games I mentioned that MOST of the world hasn't even played. We see some REALLY great PC games being made for $2-10mil, so I'm pretty sure a dev aiming at top tegra devices won't have a problem shifting titles elsewhere if needed 6 months-1yr later. They are coming with a shield update this xmas (or before) too, so at some point you're going to have millions on these anyway much like a console and that's not counting the fact that lawsuits may lead to all of mobile being NV/AMD at some point (on the gpu side, ARM whatever on the cpu side). I can see myself playing many games with key/mouse on BT when gamepads don't work right also (large rpg game like Baldurs Gate on TV for instance etc). Like I said, massive cheap ports first, then use the cash from those to fund BIG new IP. At worse making a potent game here, only means you'll wait for 2yrs for everyone to be able to play it as gpu power surpasses X1 for even the junker tablets/phones etc at 10nm. IF you don't like waiting that long port to PC etc. You seem to not understand 2Billion units are sold yearly from here on out, which means 2Billion can play any android AAA title very soon. Far faster than say, waiting for consoles to get even 50mil on either side of MSFT or Sony (what is that 5yrs from now?). I'll take the 2Billion side if I'm a dev as GDC 2014/2015 surveys both show they have.
NV can also pay $2-4mil x 25 games to get exclusives they perhaps OWN (say 20mil on 5 top exclusives yearly? Hopefully more?), and then do the same at a later date by porting to PC etc. It's not risky knowing they can port easily to the same gpu on PC. I really hope they start funding games in this range for AAA experiences aimed at X1+. At some point they'll tell us numbers sold on a unit (maybe xmas handheld or android tv here), but not likely until they have a million unit sales launch or something. Maybe they'll wait for an unreal 4 engine showcase game to give us that data. Imagine what 10nm HBM2 version of Tegra will bring to the table...ROFL. Hopefully something from AMD then too for this type of stuff.

EA, tablets will surpass consoles, and add more to the bottom line THAN consoles. Simple math. Starting 2017 consoles have a real problem if not before as better games launch. HBM2 with 10nm socs will make some waves in replacement devices for what we have today and many problems will be created even at 14nm shortly as everyone rolls that out probably a few devices using HBM1 too in this next gen of ARM devices etc. WiiU just hit 10mil devices sold, and they have some AAA experiences correct? ;) Vainglory from iOS just got ported to NV. Between apples next devices (A9), NV's current and their next model at xmas, qcom's next model (after 810), etc you will have a 100mil+ (likely far higher) that can do X1 gpu levels and likely with 128bit bus everywhere adding more fuel. I really don't get your point ;) Have you seen modern combat 5 blackout or asphalt 8, Order & chaos online, Dungeon Hunter 4 etc? Not angry birds and neither aimed at X1 levels. Haters gonna hate I guess...

I doubt he'll even read your comment but I can say, thank youJumangi - Friday, May 29, 2015 - link
It has nothing to do with capabilities. Try and understanding what I was actually saying. No developer is going to invest the time and money needed to make high end games for this thing. The return on investment isn't even remotely there.Odey - Friday, May 29, 2015 - link
I am really not sure what you are talking about. Border Lands, the new Metal Gear, Doom3, Half Life, Star Wars series, Portal, Shadow Run, and many more..and I am sure that they will get the newer games as well.heygeo - Friday, July 31, 2015 - link
I understand what your trying to say and also agree, its about having limited engineering resources and the IMMEDIATE return on having them churn out product that will have the best chance of selling the most... in other words when you look at who out there owns this thing (remember not talking about all Android users just the ones with the graphical horsepower) its minute vs say PCs and consoles... while gaming is a passion to us its a business to them and in a crowded gaming platform field this one doesn't have the user base or differentiation to stand out.farble1670 - Friday, May 29, 2015 - link
Xbox / PS4 for the poor?if you look at the reasonable model, the one with the 500GB drive, it's only $50 less than the Xbox One and the PS4, which are orders of magnitude more powerful than the Shield. for only $40 more, wouldn't you want a top of the line next generation gaming console with hundreds of games and hundreds more committed?
if you're looking at the 16GB model (with 10GB of usable space), you won't be able to load more than a few high-end games. you can load them onto an SD card, but that's slower, and you *can't* store game data on the SD card, so if it's a game that downloads content, you're screwed.
i wanted to love the shield, but the price is silly. there's just no way they can compete with the subsidized prices of the Xbox One and PS4.

"...orders of magnitude better..."I'm pretty sure they aren't. I'd be surprised if the consoles get more than 6x the performance.
(That would equate to something like a comparison between 10fps and 60fps for a given display size, so it's not like it means nothing, but that's not even ONE order of magnitude.)
