Wireless display technologies

AirPlay is a proprietary wireless communication protocol stack/suite developed by Apple Inc. that allows the streaming of multimedia and device screens, together with related metadata, between compatible devices. Originally implemented only in Apple's own software and hardware, the company has since licensed the AirPlay protocol stack to third-party manufacturers and it has been implemented on devices such as television sets and home audio systems. AirPlay works through either a direct peer-to-peer connection between devices or through an infrastructure local network.

Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound from devices (such as laptops or smartphones) to display receivers (such as TVs, monitors, or projectors). It uses Wi-Fi Direct to create an ad hoc encrypted Wi-Fi connection and can roughly be described as "HDMI over Wi-Fi", replacing cables in favor of radio waves. Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows&n

Wireless Display (WiDi) is discontinued technology developed by Intel that enables users to stream music, movies, photos, videos and apps without cables from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or computer monitors. Intel WiDi supports HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications sent to the TV from a PC running Windows 7 or later.

WirelessHD, also known as UltraGig, is a proprietary standard owned by Silicon Image (originally SiBeam) for wireless transmission of high-definition video content for consumer electronics products. The consortium currently has over 40 adopters; key members behind the specification include Broadcom, Intel, LG, Panasonic, NEC, Samsung, SiBEAM, Sony, Philips and Toshiba. The founders intend the technology to be used for Consumer Electronic devices, PCs, and portable devices.
