[Q]DVB-H Wifi on Android

I'm an Android Developer from South Africa and only now we got this technology that is 'Mobile TV'. Some phones support the DVB-H Directly, but for those that don't there is a device that receives the DVB-H and then relays a different signal over wifi for PCs running windows and there is also an app already for iPhone running iOS to connect to this device.
Is there any way to have a similar app for Android ? How would I interpret the signal over the wifi from the device (called Drifta here in South Africa)?
I want to see if it is possible if I can develop my own app for this device or if someone else already did.

This may or may not help you:

You would basically have to know about the data being sent out. What format the packets are in, etc...

Any news on this? Did you manage to get it right?

so is it certainly no hdmi or mhl ?

as the topic there are no way to connect from phone to tv?

there is no HDMI type-D port.
There is no MHL support through USB that we know of.
They really want to sell the Q. I think it's a great device, and Made in the USA too.

sadly, i live in australia so and they dont sell the Q here yet, but... it would be nice to hook the phone up straight to the TV

I certainly hope the Q bombs or you'll probably see fewer devices with hdmi in the future.
And it's just streaming from google play store that's it. Not local files, I'm not sure about games, and say you want to use your tablet as a barebones pc for a spare room and just browse the web, email etc on your hd tv. I don't believe you can do those things with the Q.
So tell me, why is worth it to lose the above for 300 bucks? So I have more audio outputs and friends can queue their music from the cloud?
Cause google knows if hdmi was included, most people would say this is good enough and wouldn't bother with the Q. Or am I missing something magical this device does?

Note lack of anything mentioning HDMI or MHL.
This is a cheap device, Asus\Google probably didn't want to pay the licensing fees.

this is holding me back a little before pre-order it
damn it

Keep your fingers crossed for products that can mirror the screen to the TV using WIFI. xBounds comes to mind. that would be even better than a cable hooked up to the tv as those cables are usually not that long.

But with wifi, i must have a tv-ethernet port

As far as I know Asus has never had MHL on one of their devices.
Samsung yes (Think Nexus). Asus no (Think Nexus 7).

no. there is a wifi dongle that plugs into the hdmi port of the TV. the nexus would sent the data to the dongle which converts it to a TV signal.
its actually quite genius if you ask me, but not quite sure why its not available yet?

Miracast on the Nexus 7?

In articles released today, Nvidia said the Tegra 3 chipset will support miracast (an open streaming tech similar to DLNA) for mirroing/streaming to other devices/ monitors. Will the Nexus support this and would this be their workaround for forgoing the MHL/HDMI? Or would it only be on future models? -Ara

I'm very curious about this too.

I've looked into this briefly and from what I gather, any device that supports WIFI direct should be able to do this. I think I read somewhere that the N7 has wifi direct. Miracast is only a standard. There are other non-standard devices out there that can also do the same thing, but requires changes to the core android files.
Search for xbounds on youtube and the internet. You will see some demos of it. it requires an hdmi dongle that has wifi on it that communicates with your device.
In any event, if the N7 doesn't support miracast, it will support xbounds via a custom ROM (if and when somebody decides to build a custom ROM with xbounds integrated). Then all that is required is the xbounds dongle. Unfortunately, there is not much information on xbounds and when it will be released.

What would I need to purchase to get this working?

Hopefully, we don't need to buy stuff, we just need to update our devices when miracast comes down. There's a list of compatible devices on the Wi-Fi Alliance website. -Ara
EDIT: here's a link to the tegra explanation of miracast, taken from an article on the issue. Yeah, a dangle may be involved depending on the setup. http://www.nvidia.com/content/PDF/tegra_white_papers/tegra-miracast-whitepaper-final.pdf

I've not found any hardware that you could plug into say an HTML Monitor that will work with this yet. I do think it will be coming available soon though.

hope so
I reckon it will work with a Nexus 7. Hopefully the dongle isn't too expensive and my Nexus 7 will be my new PSone.

Shouldn't need a dongle. Maybe a Raspberry Pi but everyone should have one of those anyway Search "Android Transporter" for more info.

Nexus Q might get Miracast support
Nexus 7 and most Tegra 3 (also Galaxy S3) phones/tablets can get a fw upgrade to enable miracast (most that support WIFI Direct probably can have Miracast enabled).
Now that google is having another round of tinkering on the Nexus Q before release we might end up with Miracast support in it as well.
Personaly I think Miracast will be added out of the box and maybee even Google TV.
I only hope that it won't be possible to disable mirroring from inside an app using the API, if so I'm sure some streaming services will disable mirroring of the screen while using there apps lika HBO Go have done to Airplay

Using a Raspberry Pi would be like a dongle... I'd like to get my hands on one to play, currently, there is a 12 week delivery time on those as well and you most likely would want it in some sort of case for it as well.
While most likely a solution, not a real clean one for mass marketing. That will come though.

Hopefully it does include support, but that is still a bit pricey and also not very portable.
Think of something you put in your briefcase, take out for a meeting, plug into the HDMI port of whatever display is in the room and play. So it needs to be portable, reasonably priced and easy to use out of the box without a lot of fiddling with it.

widi and Miracast adapters
I am thinking that these will do what we need on the display side. Now to enable it on the Nexus 7.

Has anyone heard any updated news on miracast? I tried Google but all I found was old news. I'm really tired of waiting.

Does Miracast Require Dual Band Wifi?

Miracast is missing from Nexus 7's Android 4.2 release and we are all sad... and now you are seeing people say that Miracast will never come to Nexus 7 because it doesn't have Dual band wireless which is required.
Well I don't believe that Miracast requires Dual Band and here is why (good intro right?.. I wrote it myself)
Quoted from the Miracast whitepaper:
To be certified for Miracast, a device must also be Wi-Fi CERTIFIED for:
• Wi-Fi CERTIFIED n
• WPA2
• Wi-Fi Direct
• WMM
• Wi-Fi Protected Setup
While it is expected that TDLS certification will be commonly pursued for Miracast–certified devices, it is an optional component of the Miracast certification process. Miracast and TDLS are complementary, and vendors seeking Miracast certification for their products have the flexibility to choose whether they want to support TDLS.
Click to expand...

The only thing I see see in the required list that would possibly have a bandwidth requirement would be Wi-Fi Direct (please correct me if i'm wrong) and Wi-Fi Direct doesn't require 5Ghz
Quoted from Wifi Alliance's FAQ page (http://www.wi-fi.org/knowledge-cent...-wi-fi-direct-certification-program-work-both):
Does the specification underlying the Wi-Fi Direct certification program work on both frequency bands?
Yes, the specification underlying the Wi-Fi Direct certification program supports operation in both 2.4 GHz and 5 GHz. Devices operating in the 2.4 GHz frequency band only and devices operating in both the 2.4GHz and 5 GHz frequency bands can be certified under the Wi-Fi Direct program. Not all Wi-Fi Direct-certified devices will support both frequency bands, however, so you should check which bands your devices support.
Click to expand...
Click to collapse
The TDLS Comment is interesting however as it does deal with Dual Band devices (see below). But again TDLS is optional for Miracast.
Quoted from TDLS Whitepaper (https://www.wi-fi.org/sites/default/files/uploads/20120808 TDLS White Paper FINAL.pdf):
In addition, TDLS also provides support for devices to negotiate an alternative channel. For example, if the two TDLS-linked devices are dual-band they may choose to dynamically switch to a 40MHz 802.11n channel in the 5 GHz band. The net result is a significant improvement in performance, latency and network capacity.

It may perform like crap or have to be set to a hidiously small resolution (which could explain why Google decided to not include it off the bat) but there seems to be no reason why it won't work once some custom ROMs/APKs come out for it... Deep breath everybody.
Also, I'm a newb here and can only post every 5 mins till I get some "Thank-Love." If this helped anyone I'd sure appreciate a thumbs up.

To add to this, esrlabs made their own variant of miracast called android transporter and it's only currently for the nexus 7. It doesn't have sound current as it was just a tech demo.

OP sounds right to me. Dual band is just nice to have because you could hypothetically segment Miracast from non-Miracast traffic. It's not necessary so I can imagine the N7 will support Miracast in due time.

The more I think of it, the major rom builder may shy away from building miracast into future builds for fear of infringement. Not sure how its all licensed but its very likely that the miracast portion is proprietary.
Our best hope may come from independent ports. Time will tell.

I don't think so, Miracast is an open standard by the Wi-Fi Alliance. It probably costs money to be Miracast certified but ROM builders don't care about that.
Miracast is built into the 4.2 firmware for N4 but not yet N7 and N10. Why is that? Look to to the quote below from the Miracast wikipedia page.
Miracast software needs low level access to hardware supporting Wi-Fi Direct, there is no portable Wi-Fi Direct API for different SoCs and platforms. The lack of a single Application Programming Interface compatible with different Wi-Fi Direct supported hardware platforms makes it difficult for software developers to design portable Miracast Source or Sink applications.

I think it will just take some time. Less than six months, hopefully.

You are right Wi-Fi Direct doesn't require 5GHz. I have the PTV3000 and I am stuck on my Nexus 7 at the same point I am with my 3 month old ASUS laptop with 3rd Gen Ivy Bridge i5. My laptop has a Qualcomm Atheros AR9485 wireless network chip. The Atheros is only 2.4 GHz but the AR9485 also includes 150 Mbps Data Rate, Atheros Direct ConnectTM peer-to-peer technology and is Wi-Fi Alliance CERTIFIED.
Intel's site is full of people ticked off that lost Wi-Di when they upgraded from Windows 7 to 8 that stopped working on their PTV2000/3000. I didn't get the PTV3000 before I upgraded to Windows 8 so I was doing a lot of research on my AR9485 that as I said is only 2.4 GHz.
So now I have a PTV3000, Nexus 7 and Laptop that none of them play together.

Netgear has sold so many of these damn ptv3000s on the basis of it being precertified for miracast and the expectation that the N7 would be. I'd love to see the sales numbers. Betting they spiked in the last two weeks and are back to almost nada. The whole situation is pretty frustrating.
Sent from my DROID X2 using xda app-developers app

Just to confirm, the ptv3000 is not certified for miracast? Doesn't it advertise that? I was going to pick one up if I saw one cheap (although with n7 currently not having miracast my interest has waned) but if it definitely doesn't I'll look elsewhere.

The ptv3000 is pre-certified. It needs a firmware update to be miracast. As of right now it doesn't even work with an N4. Best to just not buy anything until the smoke settles. Unless it's a crazy good deal... lol

miracast not working with asus infinity tf700 either, that has tye
So, after the last firmware update, my Samsung s3 can project to ptv3000 ( though i had to use triangle away on my rooted s3 first). However, no such luck wih my asus inffinty tf700, which has the same isue as nexus 7 -stuck on 2.4ghz... i read somewhere that miracast requires 2.4 ghz to connct and 5 ghz to screencast. This might be true as my tf700 does show connected sometimes, but does not creencast. Asus tech support do not confirm or deny this.

Bubble up player is great to stream from the tablet..
I use it because you can pick the device where the files are at. Say on a network computer share folder. Stream them thru the tablet to a Tv on the same network..
You can also select where the video is rendered .. Local ON THE SHARE Device or on the ..
MY Samsung shows up as a DLNA /Media device on all my networked devices . Its great feature..
YOU just have to play with the settings to find what works best with your tv and network shares.. There is also a SAMSUNG ALL SHARE App and program for windows pcs. that does NOT Require a samsung device..
As far as miracast who knows if or when....

The thing is, I don't want just DLNA playing to another device/computer/television. I want mirroring. I want exactly what Miracast is supposed to give me. And even now if you Google how to use Miracast you will find *nothing* about actually *how* to use it. You see a whole bunch of hype about people saying how it's going to beat AirPlay and how it's the best thing since sliced bread -- yet nobody has actually used it.
It's appalling how biased people can be without any evidence of the feature working (short of a video given to us by the friggin manufacturer). I feel like I purchased an iDevice. This feature is a ghost.

Exactly, feels like there are more Andro Sheep than iSheep. For now, 4.2 only brought amazing Bluetooth-NFC connectivity. As well as some UI stuff which there are plenty of custom on Android.

Well I, for one, wouldn't even be connecting it to a TV. My home theater PC, however, should easily be able to have some sort of software running on it that would be able to receive the signal. The problem is that the functionality is only half-baked at this time no matter where you look.
And without any device currently on the market, how can people swear by it?

Before we all start a witch hunt, remember miracast is still in development. You can't have something that hasn't had an official release yet.
Android Central has had a few articles on it, so far there are no official streaming devices for it (although some companies have claimed their upcoming streaming devices will support it).

Our best hope is that Google enables Miracast in a future update, and that compliant Miracast devices are released. I'm not holding my breath, since I would have thought that they would have included it with the 4.2 update if they planned on including it at all. I could be wrong of course. It's still early days with Miracast. Maybe it can be enabled via custom ROMs.
It would have been awesome to be able to stream games to my TV. Along with a bluetooth connected PS3 controller it really could have been an awesome experience.

Lazy, bad reporting.

They don't mention the 7 in the article, just the 10 and 4. I don't mind living without mirroring (my phone has MHL, if I ever bother to buy the adapter), but the wireless mirroring was a selling point on this tablet for me, even if I have to go custom to enable it.
As a filmmaking student, the capability to control and mirror screens on, say, a movie set, or a classroom, without plugging everything up just so, sounds pretty sweet. And I'm personally just tired of collecting single-use cables and adapters.
Patience, however, is a virtue, and I am willing to wait for Google to get off their asses once the mob realizes the shortchanges they're giving us. -Ara
