No Miracast in N7 3G (or plain N7) either:

http://arstechnica.com/gadgets/2012/11/googles-nexus-7-gets-a-fresh-coat-of-paint-for-the-holidays/

"Android 4.2 on the Nexus 7 has no major surprises: all of the features we mentioned in our review are here, with the exception of Miracast (which is only supported on the Nexus 4 for the time being) and the new camera features (which are present if you install a third-party camera launcher for the front-facing camera). Multiuser support and lock screen widgets, two features that weren't ready in time for our main review, are also here, but we'll be examining them more closely in a separate article."

Miracast will be available after the update. Which happen last night. Now all you need is a receiver to do the handshaking. The netgear one would do and after it is on you wireless network you would just stream to it like you would a windows media extender. By 2013, so early next year tvs once they start calling them smart tvs :cyclops: will have this feature built into it. Here we come google tv. wouldnt that be sweet to have a nexus 60 inch tv?? or bigger.

n4, n7, n10, ntv, n60 maybe?? i see it happening.

Just to be clear to any readers out there, whether or not there will be Miracast support for the Nexus 10 is unknown and anyone stating otherwise is speculating. What is known is that there will be Miracast for the Nexus 4, but no official reports from google have come out for the Nexus 10.

Copied from Exynos 5250 thread -

"Came across this while researching Exynos 5250. Looks like the hardware is very capable to handle the WQXGA resolution with memory bandwidth and power to spare. This white paper also mentions the support for 1080p 60fps wireless display. So I hope Miracast will be reality as well, just Google needs to step up and utilize the hardware to its full potential.

Here's another piece of evidence to support that it's coming to the Nexus 10 (found this from another forum). On Google's Nexus 10 Support page it mentions Miracast. Scroll down to the Wifi-Direct section:

I phoned Google Tech Support this morning and asked if the Nexus 10 would have Miracast functionality "out of the box".

Tech guy couldn't answer for sure and promised to respond back to me later via email.

5 hours later, amazingly (to me anyway), I received an email back from him stating that he got clarification on this question and that, yes, Miracast is good to go "out of the box" on the Nexus 10.

I still won't believe it until someone with a unit confirms it. ;)
[Nexus 10 General] Croak:
Miracast is basically just a superset of WiFi Direct, doesn't require any additional hardware on the broadcast device...if it can use WiFi Direct, it can do Miracast with the proper software.

So I'm not worried about it being on the N10, if the software isn't there just yet, it will come.

http://en.wikipedia.org/wiki/Miracast
[Nexus 10 General] MSmithXDA:
Yeah, I had called them and asked them too. He had no idea what Miracast was and so I explained it to him. He said he'll have to ask his supervisors and put me on hold. He came back and said "Yeah, you can stream and watch movies on your tv from your tablet and stuff." I said, "Yeah, but specifically Miracast...Does the Nexus 10 support Miracast?" He then said that's more of a hardware question and I'd need to call Asus. Asus huh? Interesting. Are they taking Samsung support calls now. I just ended it there knowing I wasn't going to get anywhere.

---------- Post added at 05:34 PM ---------- Previous post was at 05:30 PM ----------

My understanding is that while the capability might be there if Wifi-Direct is there, it still doesn't mean that it will be Miracast certified and thus might not be supported by Android.

[Nexus 10 General] gserp4sox:
FWIW, I have a Galaxy Nexus running Jelly Bean 4.1.1, which supports Wi-Fi Direct. I also have a Netgear PTV3000 WiDi/Miracast capable adapter. My phone sees the adapter, but there is no mirroring to a display.
[Nexus 10 General] crazy talk:
you must have missed the part where Miracast is a 4.2 feature?
[Nexus 10 General] gserp4sox:
No, just sharing that a WiDi/Miracast capable adapter recognized a Wi-Fi Direct device, a substantiation of Croak's earlier post.
[Nexus 10 General] MSmithXDA:
I'm now of the belief that the reason we haven't heard something official from Google is because the Nexus 10 has been submitted for Miracast Certification but is still under review. Makes complete sense. They can't say it supports Miracast until it passes Miracast Certification. They don't want to say it doesn't because they think they'll ultimately get the certification. So for now they just stay silent. Whereas the Nexus 4 has already completed Miracast Certification so that one they could officially announce. Perhaps the same reason they've been silent on the Nexus 7, which being that it has a Tegra 3 in it and Nvidia says Tegra 3's have built in support for Miracast and are working towards certification, should mean that theoretically it is capable.
[Nexus 10 General] thebballkid:
That actually makes a ton of sense. I also read somewhere that Netgear is working on updating the software on its PushTV3000 to support the Nexus devices that have Wifi Direct/Miracast. They hope to have that done by next week, apparently.

I don't know if it will become available as part of a future update, but I know I won't plunk down my hard earned money until I can get a tablet with 1080p Miracast support (preferably in a 7" form factor). I would have pulled the trigger on the Nexus 10 if it had Miracast support.

>I don't know if it will become available as part of a future update, but I know I won't plunk down my hard earned money until I can get a tablet with 1080p Miracast support

That may be a long time for tablets. There was a recent article where the authors had used N4 and Optimus-G with Miracast (at LG's facility). One finding was that the phones can only access the net via their cellular link while using Miracast, as wifi is tied up for the Mira link.

This makes sense, as you can't normally connect to two different networks with a single NIC. What it means is that wifi-only tablets can't do Miracast, not unless vendors start putting a dedicated NIC just for that purpose (not likely). Along with various other constraints on the tech itself, my assumption is that Miracast won't happen on N10, ever. It's hardware thing, and isn't something custom ROMs can fix. Major bummer.

More detail below, along with link to the article:

Although true that a network adapter can only be connected to one network at a time there are ways to virtualize adapters that would allow this functionality. If there is enough bandwidth on the one adapter to pull an HD movie from the net and send it over simultaneously to a wireless display is another question however.

If there is enough bandwidth on the one adapter to pull an HD movie from the net and send it over simultaneously to a wireless display is another question however.

This begs the question of whether there's any existing implementation of virtual NIC on Android. I couldn't find one from a cursory search. I would like to see one in action if you have a link, since it would be useful for more things than just for Miracast.

A workable solution would be to do the same as Apple AirPlay and Intel WiDi, and route Miracast through the existing network rather than create a new ad-hoc direct link. The downside being that this lacks the robustness of a direct link at short wifi range. Apple can get away with going through the home network since it has more end-to-end control. (Apple users are more likely to use Apple networking hardware, as vs the usual mish-mash of crappy 2.4GHz equipment.)

This--the vagaries of consumers' wifi quality--was likely why WFA opted for the direct-link rather than AirPlay's method. Even if it were to change course and add infrastructure connection as a Miracast addendum, modifying the standard would mean at least a few months' delay.

Another solution would be to use a USB wifi adapter (taped to the back of the tablet, say) for the second link.

OK, I retract my assertion that this won't be doable for an enterprising custom ROM'er. Still, it would be a major undertaking that would be best handled by Google. Given Goog's track record on wifi direct, I'm not terribly optimistic. Let's all hope it'll be a headliner feature for KLP, although by that time we'll be looking at Nexus 10 v2.0.
[Nexus 10 General] miiike:
I'm only saying it's feasible from a software standpoint as it's been used by all of the major virtualization companies for desktop/server systems. If there is any sort of implementation for Android i'm unaware.

Can Miracast be added in the future or does it require some sort of hardware and it just wasn't added to this device?
[Nexus 10 General] borchgrevink:
So many theories. To me it just seems like nobody really knows.
[Nexus 10 General] MSmithXDA:
Nobody does know. It's all just theories and guesses based on the available data.

What we do know is:

1) Android 4.2 supports it when installed on the proper hardware

2) Device must at least contain a Wifi-Direct chip

3) To work, device will most likely need to be Miracast certified

4) Nexus 4 officially supports it

5) Google posted official support pages showing Nexus 10 supporting Miracast, but recently pulled them.

6) Google officially says that "CURRENTLY" only the Nexus 4 officially supports Miracast

What we don't know is:

1) Whether Nexus 10 or 7 will ever support it. However, Nexus 7 has the Tegra 3 chip, which Nvidia is promoting as having been designed to allow it to be compatible. And also Nexus 10 has a Wifi-Direct chip. So, promise is there for both of them.

2) If it's true that for it to work you will need either a second Ethernet on the device, or 1 Ethernet and 1 Cellular. It's possible single Ethernet devices will still work but will just lose their network connection, or maybe dual band Wifi can be harnessed to keep the connection alive (Nexus 10 has dual band), or maybe a software solution overcomes this problem.
[Nexus 10 General] e.mote:
Well, maybe there's hope yet. From the article below, Goog is serious about getting its AirPlay on, so the Miracast (mis)step apparently won't be the last word. The piece has no specifics other than a few words from Goog's Product Dude, but taken at face value, we can expect TV connectivity to be a headline feature in 5.0 for next I/O. BTW, this would be a shot across MS SmartGlass' bow as well. Competition is good.

My inner cynic says the new toy is already old, and this will need new hardware. But I'll err on the side of optimism and hope for either vNICs or some other software solution for current toys (N10 mainly). It's worth a New Year's wish, no?

There is no Wifi Direct chip. Wifi Direct is a standard which to date has only been deployed for NFC use, AFAIK.

Airplay vs Miracast

Have I understood this correctly?

Miracast is true screen mirroring which means the complete desktop as well as games are visible on the Miracast enabled TV

AirPlay is just like a TVbox with DLNA client which gets the video file from Iphone? It also seem to have some playlist/browsing capabilities and so on which you can control from your Iphone but in that case, what you see on your Iphone is not displayed on the AirPlay screen?

Not possible to show the Iphone desktop or games?

Is this correct?
[Nexus 10 General] e.mote:
>Miracast is true screen mirroring which means the complete desktop as well as games are visible on the Miracast enabled TV

From abovementioned "N4 & Opti-G hands-on" piece, Miracast in Android is also an app-level function that allows app-specific output, in addition to display mirroring (aka screencasting). Practically, it's hard to say, since there's yet no working Miracast adapter, and thus no working Miracast setup in the wild. It'll be a 2013 thing.

Miracast does real-time H.264 encoding of screen content (as are AirPlay and WiDi), thus latency will be an issue. Highly interactive activities like action gaming and typing won't work well due to lag. Moreover, since Miracast's max spec is 1080p@30fps, large-res screens like N10 will incur a loss in fidelity as display is downscaled to 1080p. This may impact text-intensive uses. The solution to this would be non-compressed or lightly-compressed data beaming, but that would require higher bandwidth, which should be forthcoming in WiGig and similar techs.

>AirPlay is just like a TVbox with DLNA client which gets the video file from Iphone?

AirPlay started out as AirTunes and gradually expanded to include video. With AirPlay Mirroring introduced last year, it now does screencasting. Functionally, it's a superset of both DLNA and Miracast. The most important feature of AirPlay is that configuration is automatic, which is one less headache for the non-techie user. "It just works--as long as you buy Apple hardware." This ease-of-use is reflected in Miracast's own auto-config, and would presumably be mandatory for any tech that hopes to capture the living room.
[Nexus 10 General] MSmithXDA:
True. I didn't explain that correctly. What I should have said was that Wifi-Direct requires certification. From what I understand, the wireless chipset used in the device must be certified for Wifi-Direct in order for it to qualify for it ever becoming Miracast certified.

New Miracast toys

Some interesting new toys, reportedly of Miracast tech, from an Chinese outfit at http://tmindtech.com . Not much info on the site. I've sent for a RFI.

Latency in this 1st vid is 1+ sec, and framerate obviously struggling at 1080p. But as the saying goes, it's not how well the dog can sing. Weird that a mouse is needed on the TV/dongle side to connect. "Miracast" may be a borrowed label-of-convenience for a different underlying tech.

Edit: Dongle is apparently a stick PC (Android) with wifi capability.

This second vid is interesting in that the TV is the source and the phone is the sink, even as the phone is controlling the TV. The tech displayed (in vids below) is apparently fairly flexible, allowing for a variety of devices as input and output.

I was thinking about what someone noted in a previous post regarding the N4 having 3G and Wifi. The speculation that Miracast takes over the wifi and that is why it's not on the N7/N10 does not make sense when you consider that the Galaxy Note 10.1 do AllShare Cast sharing with supported Samsung TVs and it has been stated that AllShare Cast is Samsung's version of Miracast. The S3 is actaully Miracast certified but uses AllShare Cast probably because Miracast stardard was not ready yet.
[Nexus 10 General] MSmithXDA:
I don't buy it either. I would find it really odd for an entire industry to get behind a technology that has such an obvious fatal flaw, especially when the flaw doesn't exist in the major competing technology.

Thanks for the search term. <tap tap in Googly box>

Well, G.Note 10.1 does have cell connectivity, so conceivably it could've used that for net connection.

But apparently you're right. Everything looks to go through wifi.

I suppose next step is for N4 peeps to get a working Miracast adapter, then we'll see what happens for N10 & co.

I did not experience any loops as he was afraid of, no errors at all and it seems stable.

The OTA package seems stable but Miracast may or may not work.

I do have "Wireless display" in the menu now. I also believe searching for miracast receiver was working the first time I booted the tablet. Unfortunately I didnt have a miracast receiver nearby then and when I got home it seemed like I had lost the possibility to search for receivers.
