Miracast is a standard for wireless connections from sending devices (such as laptops, tablets, or smartphones) to display receivers (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.
The Wi-Fi Alliance launched the Miracast certification program at the end of 2012.Devices that are Miracast-certified can communicate with each other, regardless of manufacturer. Adapters became available that may be plugged either into HDMI or USB ports, allowing devices without built-in Miracast support to connect via Miracast.In 2013, Nvidia announced support for Miracast.
Miracast employs the peer-to-peer Wi-Fi Direct standard. It allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation – 16 bits 48 kHz 2 channels).The connection is created via WPS and therefore is secured with WPA2. IPv4 is used on the Internet layer. On the transport layer, TCP or UDP are used. On the application layer, the stream is initiated and controlled via RTSP, RTP for the data transfer. (by Wikipedia)
