Miracast, created by the Wi-Fi Alliance, is a p2p wireless screen casting standard via Wi-Fi Direct connections. It enables wireless delivery of audio and video (up to 1080p HD video and 5.1 surround sound (AAC and AC3 are optional codecs) to or from desktops, tablets, mobile phones, and other devices. It allows users to echo display from a phone or tablet PC onto a TV, share a laptop screen with the conference room projector in real-time. Both the sending and receiving devices must support Miracast technology. However, to stream music and movies to a device, such as a TV or projector without Miracast support, a Miracast support WiFi display adapters in needed to plug into HDMI port, thus Miracast can be regarded as a Wireless HDMI cable.
Miracast support is built into Android 4.2 or later, BlackBerry 10.2, and Microsoft Windows 8.1. Another way to support Miracast in Windows is with Intel's proprietary WiDi v3.5 or above. Apple’s equivalent WiFi display technology is its own AirPlay mirroring on OS X, while for Linux desktop there was MiracleCast which provides early support for miracast but is not tied to that single protocol.
