Miracast, Android phone to connect wirelessly to TV

Hi friends, today I will show you how it works Miracast. If the iOS (iphone, ipad, ipod) have Airplay Mirroring on some newer laptops have WiDi on Android we Miracast or screencast.
Miracast is a protocol that helps us on the TV screen without wires, just you see on your phone or tablet, a kind of HDMI Wireless.
To use miracast we need a phone that supports screen mirroring (Jelly Bean or KitKat), exactly who is operating system and hardware required for it, besides we need a phone Miracast compatible TV or a android MiniPCI you to use it in case you do not have a Miracast compatible TV.
The connection between devices is done via WiFi Direct (not local network), this means that do not need to have a router for whatever connection is directly between the transmitter (phone) and reciver (tv miracast or mini pc connected to tv) .
How does it work exactly?
To simplify everything, Miracast a mission to send the video signal displayed on the phone or tablet directly to the receiver. There are some software instructions that take the signal from the frame buffer, compress, pack it and send it to the receiver via WiFi Direct (not the router), just to eliminate downtime, the resulting stream reach (TV or MiniPCI connected TV), this stream is decompressed and displayed on the screen in real time (almost). Now of course, some devices will work better and others worse, depending on your phone compatibility and strength. Certainly time will finish instructions will improve the hardware and will decrease the lag, can we have a chip exclusively for Miracast, which then can be used for streaming, video encoding / decoding, archiving ...... However Miracast is useful sometimes can help us enjoy multimedia content on larger screens without cables even DLNA could do that, playing movies or photos from your phone or PC to your TV but with some limitations.
For those who do not know the phone can run DLNA TV only video, photo or audio, Miracast displays what is seen on the phone or tablet.
Even if your phone supports Miracast, and not necessarily work. I met this problem when I used the Nexus 4 for Miracast connection, connected and disconnected after a few seconds. There must be some compatibility between network faces the transmitter and reciver. In the same setup, with LG G3 not had any problems. Certainly the way the Nexus wifi 4 (Murata) is not well understood and wifi module of MK 908 (Broadcom).
Experience is pleasant to the gaming, where it is almost impossible to play in television watching, the lag is too high.
For movies, youtube, apps, facebook, web browsing and other light things go, unfortunately gaming is not a solution. I would have liked to work with a bluetooth controller connected was a dream mini console without wires.
If you need a fast wireless connection between TV and phone or tablet just for video, photos or music, we tutorial and about DLNA technology.

I guess the TV, sees the phone and vice versa, tries to connect, after which the message "device is disconnected" (on TV) The phone is saying that it is not connected via the mirror screen although it is activated on the phone. Is the TV a problem? Is it warranty and if this is the problem I will solve, but I do not want to make myself laugh if it's just from the settings .Pages can be seen from the phone on the TV, only the screen mirror function (phone screen) can not show it any way. This TV also often gives me the error "insufficient memory, the application has closed". Although outside of youtube and google I have not installed anything on it. That's what I guess yet.

  19. I tried a multitude of applications mating Phone-SmartTV, gender iMedia Share, Bubble UPnP, All Cast, Air Wire, WIFI Display, kinome Connect they use now, but none of these applications for Android, not read all movies with subtitles, you open the SmartTV
    If you have no idea who makes application to read subtitles to movies at the time when Android is paired with Smart TV will beg leave a comment if you have no idea.
    Um and another question! Do you know an application for android, transfer files Wifi, ANDRIOID-PC and PC-ANDROID, apart from the one you presented it in an older tutorial
    A good day!

    • Adrian Gudus said

      Tried MX Player? If not, you can integrate subtitles in the film, we already have tutorial on this subject, you find using the search box top right. Or search tutorial "How to watch movies with subtitles on Android phones and tablets"

      • Adrian Thanks for the reply, but I think I was not well understood or not I express myself better in writing!
        It is not MXPlayer! It is perfect with corresponding codecs, I watch movies directions on your phone or tablet with subtitles .... or direct the film about integration subtitle.
        MX player I know very well in all his settings and integration methods under the same.
        They have nothing to do with what I want.
        *** The method is like that of YouTube, when you are on the same wireless network and can to open a video on SmartTV directly from your phone or tablet via a single touch of icons ***

        I say: When I open a movie SmartTV by mating method Wifi devices with an application of the above listed me, can watch movies in perfect conditions but ... .fara subtitles.
        Players of this kind of applications tested me, can not read the subtitles, and applications of this kind do not leave me to set another player base, that would be great to be able to directly open in MX Player, the SmartTV, impossible momentary
        I folosec kinome Connect wifi was conducted to pair the phone or tablet SmartTV site, but the player base of this application can not read subtitles.
        From what I have seen, there are no settings to configure another player base, in applications you've tried it.
        !!! I wondered if you know an application listed in the kind of me, who can open movies with subtitles when mating wifi, phone or tablet with SmartTV site.
        Methods like put subtitles on the film directly with VirtualDub, Total Video Converter,
        a practice the days when phones were "stupid" not to take direct knew subtitles, do not want to go back to those times ..
        And ... sorry! ... Reiau question!
        Do you know a free application for Android, transfer files Wifi, Android, PC, Android and PC, apart from the one you presented it in a tutorial older.
        Thanks for your understanding if you understand something, should I not return again to the internet in Trencher
        leisure, until I find something useful.
        Have a good day!

  20.
