What is Miracast
Miracast is a wireless communication standard promoted by the Wi-Fi Alliance and supported by the vast majority of portable and non-portable devices (smartphones, tablets, Windows PCs, etc.) and by modern Smart TVs.

With Miracast you can wirelessly connect the screen of your portable device to the TV, playing any multimedia content: music, video, streaming, images will be available on the large television screen. Represents a valid for connection via HDMI cable.

Below you will find the standards supported by Miracast for sending the audio / video stream:

Video up to 1080p (H.264 codec).
5.1ch surround sound (with AAC or AC-3 codec).
WiFi Direct (direct communication between two devices).
The transmission is very stable, also offering a latency (delay between what happens on the mobile screen and what you see on TV) low enough to take advantage of the connection to play a mobile video game on a TV screen.

This technology can be exploited to transmit audio/video content (stored in the device memory or streamed via the Internet), dedicating the smartphone to the role of “remote control” of the contents sent and transmitted to the TV via Miracast.

Miracast compatibility
In order to use Miracast, it is necessary that both devices, both the mobile device and the Smart TV support this technology: they must be “Miracast certified”.

As for the mobile device, it is relatively easy to get support because:

Android natively supports Miracast from Android 4.2 (onwards).
Microsoft supports it with Windows 8.1 and Windows 10 (even on mobile devices).
Apple, on the other hand, for its iOS devices (iPhone and iPad) uses its “AirPlay” transmission standard (in fact a competitor of Miracast).

TV side most TVs with built-in WiFi support Miracast. The problem is how to enable support, as each manufacturer prefers to call this technologist differently.
