Miracast is a peer-to-peer wireless screencast standard formed via Wi-Fi Direct connections in a manner similar to Bluetooth. It enables wireless or wired delivery of compressed standard or high-definition video to or from desktops, tablets, mobile phones, and other devices. Both the sending and receiving devices must be Miracast certified for the technology to work. However, to stream music and movies to a non-certified device there will be Miracast adapters available that plug into HDMI or USB ports. Miracast allows a portable device or computer to send, securely, up to 1080p HD video and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation — 16 bits 48 kHz 2 channels).However, it works only over Wi-Fi and cannot be used to stream to a router access point.It was created by the Wi-Fi Alliance and billed as an open alternative to Apple's AirPlay Mirroring. It allows users to, for example, echo display from a phone or tablet made by Company A onto a TV made by Company B, share a laptop screen with the conference room projector in real-time, and watch live programs from a home cable box on a tablet.
