Both the sending device (such as a phone) and the receiving device (such as a TV) must support Miracast.
Miracast supports both video streams and screen sharing (sending a live image of everything on the screen to another device.)
Miracast supports HDCP for protection of copyrighted content.
Miracast the main brand for Wi-Fi Display technology.
