I'm thinking of an app for Samsung SmartTV which, besides other information, displays the currently running TV program.
Since I haven't found any documentation about accessing and displaying the TV program inside of an app, I was wondering if this is even possible. Has anybody further information?
Thanks,
Markus
Yes, it is possible to show TV signal inside your SmartTv application. Guide to do that can be found here: http://www.samsungdforum.com/Guide/tec00103/index.html
However, make sure you read the note at the end of that guide. Mixing TV signal and app content needs approval from broadcasters, which can result in locking your app for only a specific TV channel. It goes the same for ticker applications.
Be really aware about the fact that in EU you cannot overlay even part of the screen of the broadcasted channel by TV application content -> such an application will not approved by TV vendors unless it is for specific channel only for which you must have an agreement - but this is typically more task for a HbbTV...
That regulation is quite limiting - because otherwise you can have nice eweather or sport betting widgets overlaying the screen during e.g. tennis or football match. I am however not sure about similar restrictions on other markets like e.g. MENA or Latin America.

Is there an LG tv app to display the list of messages from a text file or any other( xml...) from network or USB just like the breaking news in the tv?
The video must keep playing and the messages should pop up and repeat from the file.
I need it to display my office account informations on LG smart TV. Please reply. Thankyou.
If there aren't any such apps, please give me guidelines to build one from the sdk. I mean which components to focus more.
Thankyou.
Late answer, but anyway. I connect to my '14 LG smarttv over websockets on port 3000 and send the following as JSON after connecting:
{"id":"0","type":"request","uri":"ssap://system.notifications/createToast","payload":{"message": "Super mega awesome."}}
This will make it show a toast for a while.
But, first you must pair with the TV. It may be easier for you to simply use the ConnectSDK.
I'm trying to figure out a way to mirror an iPad screen to other iPads. This doesn't seem to be supported on the platform though.
Basically, a teacher would have an iPad, then the students would have iPads and see everything that is happening on the teachers screen, but on their screens.
Thoughts?
I have been attempting to find a solution to this problem myself. I have not found any apps that can mirror exactly what is happening on another IPAD, but some come close.
RabbleBrowser and Ideaflight both had potential. Ideaflight appears to be more for business. RabbleBrowser appears to allow the mirroring, except it only works as a browser and a file/picture mirroring.
Both iPads are linked to the same wifi and when you join a session, they will mirror the iPad that started session. Also allows chat (controlled by session starter).
It does NOT continue to mirror if you move out of browser and into another app however. I had dreams of leading a class through a a lesson on google earth, but no go .:(
Another option is attaching a laptop to a projector. Then you download Airserver on the laptop. Go to the menu bar at bottom of iPad and turn on AirPlay. The laptop will mirror the iPad perfectly and project it! It's wireless and works well. I tried the HDMI connector to laptop but it gives a poor quality, shaky image.
Hope they allow mirroring in future updates. The capability is there, don't know why they don't! Guess trying to sell more appletv!
A similar question was asked on the Apple forum (https://discussions.apple.com/thread/3118281?start=0&tstart=0), and the following app seemed to help them or answer their question.
Have a look at Replicate Pro on the app store:
http://itunes.apple.com/us/app/replicate-pro-for-ipad/id363286515?mt=8
One feature listed in the notes:
Share files between two iPads/iPhones that are running this app. (Pro
version only)
I'm not sure if this will cover multiple devices or simply between two, but it may be worth a look. Sadly, the only way to try would be to spend $5.99.
You'll need to create an application for the student iPad that emulates the screen of the teachers iPad. I would suggest that, although i dont know if its possible, the teacher somehow starts up and app that emulates their entire iPad. Meaning, from within the app named "teacher share" (or whatever it is), they can access the music, settings, notes and other apps found on their ipad. Then that information could be sent over a network to the students.
Nearpod is an app that will allow you to mirror a presentation on several iPads. I have had up to 9 at one time. Through the Nearpod program you can make a presentation similar to PowerPoint, and also incorporate interactive questions, which can be multiple choice, short answer, and even drawings. The only drawback is the full version costs $10/month. The free version is still good, you are just limited on the size of the presentation.
After doing lots of research, I found one app which shares iPhone device into another iPhone device. Really great logic they have applied for screen mirroring.
No idea about detailed how they have implemented but after installing and checking the app I came to know that I think they have used iPhone Screen Recording and broadcasting it on to their server and then on another device they are syncing from the same URL.
OliOli a free and simple screen sharing app for iOS.
iOS App: https://itunes.apple.com/us/app/olioli-screen-sharing/id1382253993?mt=8
WebSite: https://olioli.io/
I am researching how to create an app for my work that allows clients to download the app (preferably via the app store) and using some sort of wifi triangulation/fingerprints be able to determine their location for essentially an interactive tour.
Now, my question specifically is what is the best route to take for the iPhone? None of the clients will be expected to have jail broken iPhones.
To my understanding this requires the use of the wifi data which is a private api therefore not meeting the app store requirements. The biggest question I have is how does American Museum of Natural History get away with using the same technology, but still available on the app store?
if you're unfamiliar with American Museum of Natural History interactive tour app, see here:
http://itunes.apple.com/us/app/amnh-explorer/id381227123?mt=8
Thank you for any clarification you can provide.
I'm one of the developers of the AMNH Explorer app you're referencing.
Explorer uses the Cisco "Mobility Services Engine" (MSE) behind the scenes to determine its location. This is part of their Cisco wifi installation. The network itself listens for devices in the museum and estimates their position via Wifi triangulation. We do a bit of work in the app to "ask" the MSE for our current location.
Doing this work on the network side was (and still is) the only available option for iOS since, as you've found, the wifi scanning functions are considered to be private APIs.
If you'd like to build your own system and mobile app for doing something similar, you might start with the MSE.
Alternatively, we've built the same tech from Explorer into a new platform called Meridian which provides location-based services on both iOS and Android. Definitely get in touch with us via the website if you're interested in building on that.
Update 6/1/2017
Thought I would update this old answer - AMNH is no longer using the Wifi-based system I describe above, as of a few years ago. They now use an installation of a few hundred battery-powered Bluetooth Beacons (also provided by Meridian). The device (iOS or Android) scans for nearby beacons and, based on their known locations and RSSI values, triangulates a position. You can read more about it in this article.
Navizon offers an indoor positioning solution that works for iOS as well as any other platform. You can check it out here:
http://www.navizon.com/product-navizon-indoor-triangulation-system
It works by triangulating the WiFi signals transmitted by the device. Since it doesn't require an app to run on the phone, it bypasses the iOS limitations and can locate any other WiFi device for that matter.
Google recently launched an API called Maps Geolocation API. You can use it for indoor tracking of devices, which essentially can be used to achieve something similar to what AMNH's app does.
I would do this using Augmented Reality. There is a system sort of in place for this, the idea being that you place physical markers that have virtual information associated with them. I believe the system I saw was a type of bar code. When a user holds up the phone with the app, the app uses the camera to read the code and then display information. This could easily be used to make a virtual tour type app distributable through the app store and not even require a WIFI or 3/4G connection. This assumes that you simply load your information and store it locally with your app. Then to update it you simply push an update through the app store. Another solution is to use a SOAP/REST service and provide the information in that way, and this does not use private API's, though it does require some form of internet connection. For this you can see a question I asked about this topic a little bit ago:
SOAP/XML Tutorials Question
In addition, you could load a map of your tour location, and based on what code is scanned you can locate the user on the map and give suggested routes based on interests etc.
I found this tutorial recently on augmented reality, I haven't gone through it, but if its anything like the rest of Ray's tutorials, it will be extremely helpful.
http://www.raywenderlich.com/3997/introduction-to-augmented-reality-on-the-iphone
I'll stick around to clarify any questions or other concerns you may have with your app.
To augment the original answer for devs who were using Cisco MSE for indoor location - now they have an iOS and Android SDK which enables you to do indoor location using the MSE. A simulator can be used as well to develop the app without implementing the infrastructure to start with : https://developer.cisco.com/site/cmx-mobility-services/downloads/
For indoor location you can use Bluetooth LE beacons since it's a very accessible technology nowadays, there are several methods:
Trilateration: it uses 3 beacons, but with the noise and attenuation of Bluetooth signals, it gets quite difficult to determine the exact position and also it's not easy to use more than 3 beacons to increase accuracy.
Levenberg Marquadt method: used to solve non-linear squares problems showed good results on indoor positioning.
Dead Reckoning method: using the motion co-processor of the device, giving an initial position you can calculate the moving path of the device. Not that easy to implement anyway.
I wrote a post on the topic, you can find more info here: http://bits.citrusbyte.com/indoor-positioning-with-beacons/
And you can use this iOS app for your own indoor positioning experiments: https://github.com/citrusbyte/beacons-positioning
I doubt the American Museum is actually using private APIS; you'll probably find the routers that have been setup serve different responses to each other, so the app can detect it's position in the museum.
If you are looking for a cheaper to way to do the same task, you could have signs with QR codes, and use an open source library to let users scan these barcodes as they move through the museum, and update the onscreen content accordingly. On an even more low tech level, you can just tag each area with unique numbers, and distinguish that way.
I'm working on an enterprise iPhone application for a client, the issue at hand is customer information will show up on the phone. My client is worried that the information could be caught using the iphone screen capture feature (home + power button), then emailed or synced from the phone. Is there any way to disable the screen capture feature? Can this be done programatically or is is possible through a configuration profile?
if your customer could retain the ownership of a handset, they can restrict Screen Capture feature using iPhone Configuration Utility. Make sure you don't give these phones to any one outside of this organization, otherwise you are in violation of your Enterprise legal agreement with Apple.
Since this is for an enterprise app, perhaps you could put a transparent overlay view atop everything, that in a drawRect went opaque when it detected the layer was being asked to render for a screen shot (perhaps by looking back up the stack trace?)
You might try setting debug points in every possible view and layer drawing methods, and see if anything is triggered by a screenshot.
Screen capture can be enabled/disabled for iPads/iPhones that are managed via the iPhone OS Configuration Utility. See page 33 at http://manuals.info.apple.com/en_US/Enterprise_Deployment_Guide.pdf where it says:
** Allow screen capture: When this option is turned off, users are unable to save a
screenshot of the display.*
In other words, in enterprise deployments where the "customer" owns the iPads (or requires employee-owned devices to be configured by IT) screen capture can be suppressed at a device level.
It's also possible to detect if screen capture has happened and to record this (so perhaps a manager can pay a friendly visit).
It is not possible to suppress screen capture under program control. Apple prefers to exercise tight control and grudgingly yields a bit to enterprises. It doesn't yield much to developers. (How do you like being a sharecropper on Apple's plantations?)
Seriously, there are good reasons to control screen capture. In the education space, we'd like to use iPads as secure testing devices. In a proctored test environment, the proctor can make sure a student doesn't have a camera or notepapers to carry away test questions. Therefore the major remaining risk to test item security is the screen capture. If you couldn't suppress it, students could quickly snap every test question they encounter and email them to their buddies (or post them online or sell them to a test-prep company).
For random consumer iPads used under uncontrolled conditions, developers don't have this capability. Them's the breaks :-).
No, there isn't. The user is always able to perform this function.
Yes, you can do this in at least two ways. Internet Testing Systems (ITS) of Baltimore has an iPad testing app in the store, interestingly it is "PEARSON NNAT2 -Stanford 10 - OLSATS", a Pearson app that can be used to take any of these three tests. see https://itunes.apple.com/us/app/pearson-nnat2-stanford10-olsat8/id546817211?mt=8 -- it is free and you can download it.
If you simply require your user to put the device into Guided Access mode after starting the app and before proceeding, using UIAccessibilityIsGuidedAccessEnabled(), you can then prevent the user from using "print screen" -- OR from switching to any other task. Examsoft is a vendor that uses this approach.
These features are generally of concern to test publishers and assessment delivery vendors; I have a blog post and screen shots the ITS approach, and code to emulate the Examsoft approach, here: http://mindstormtools.com/2013/02/23/ipads-for-assessment-test-delivery-profile/ and http://mindstormtools.com/2013/02/20/ipads-for-assessment-guided-access/
