What is the difference between
Miracast and WiDi
What is Miracast
Miracast is a standard for wireless connections from devices (such as laptops, tablets, or smartphones) to displays (such as TVs, monitors, or projectors), introduced in 2012 by the Wi-Fi Alliance. It can roughly be described as “HDMI over Wi-Fi”, replacing the cable from the device to the display.
On 29 October 2012, Google announced that Android version 4.2+ (from updated version of Jelly Bean) are supporting the Miracast wireless display standard, and by default have it integrated. With Android 6.0 Marshmallow, released in 2015, Miracast support was dropped.
But there are a lot of Android phones also support it, such as Samsung which called “smart view”, HUAWEI which called “wireless projection”, XIAOMI which called “Cast”.
What is WiDi
Wireless Display (WiDi) was technology developed by Intel that enabled users to stream music, movies, photos, videos and apps without wires from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or monitors. Intel WiDi supported HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications sent to the TV from a PC.
In Intel Wireless Display version 3.5, the Miracast standard was supported up until it was discontinued with 6.0.
Main difference
So we can see, the WiDi on Windows is supported Miracast standard. and the WiDi has also supported User Input Back Channel (UIBC) support to allow for human interface devices (touch screens, mouse, keyboard), and Inter mouse cursor protocol.
So we can call “Miracast” on Windows 10 “WiDi”. And they can supported on Windows 10 and Windows 8.1. This post calls “Miracast”.
